Default How To: 2.0l Cam install/General cam install (w/pics)

Topic: 2.0l Cam install/General cam install
Difficulty: Moderate to hard
Amount of Time: Set aside at least 8 to 10 hours, a weekend is better as to prevent the possibility of rushing the job and screwing something up.

NOTE: Critical engine area is going to be modified. Extreme care if to be used when doing this install.This tutorial is under the impression that the installer has some basic mechanical skill/knowledge.

All right, i have seen many people state an interest in the 2.0l cam install and the same questions pop-up over and over again. Im doing this how to to help cut down on redundant questions and as a guide for when installing the cams.

Lets start with the common questions:

Q: What cam gears do i need:
A: You need to purchase the 2.4l cam gears. Just because you are installing 2.0l cams doesn't mean you need 2.0l gears. As a matter of fact the stocks gears are the same for the 2.0l and 2.4l engines. Just flipped over. AKA one side is 2.4l the other is 2.0l It has to do with the offset of the mounting area of the gear. Much like a rim for your car. If you were to put a 2.0l gear on a 2.4l motor the offset would be too deep and the gear would rub the timing cover behind it.

Q: Can i run the stock gears.
A: Yes you can, but you wont get the maximum power out of the cams. As a matter of fact you may even loose power without tuning the cams. If your going to do the job might as well do it right and get the gears. Atleast this way if you upgrade cams to a larger set then you wont have to buy gears then.

Q: What is the best setting for the cams.
A: This is hard to say. There is too many differences to set a base line setting. The best way is to tune the cams on a dyno to maximize power. Otherwise you are tuning blind and could actually be hurting yourself.

Q: Will these cams cause the motor to lope.
A: Yes they will, if tuned right. But remember just because it lopes doesn't mean you are going to be making alot of power. All your doing is increasing valve overlap. Which in a sense could hurt you more on a turbo car then help.

Ok, now that thats out of the way. Lets get onto the install.

Tools needed: A set of metric sockets 8mm-19mm (shallow and deep well), A 1/2 inch t55 torx bit socket. 1/2 inch impact and 3/8's drive impact(not necessarily needed but makes the install easier), 8mm-19mm wrench's (ratcheting helps but not necessary), 1/4 inch ratchet. In/Lb toque wrench (able to reach 250 in/lbs) 3/8 drive ratchet, 1/2inch drive ratchet, 3 jaw crank pulley puller w/ inserts) 3/4 inch deep well socket. 7/8 's deep well socket(if your using the puller i am), Angle Grinder/dremmel with a grinding disk/bit, Jack w/ Jack Stands, a 1 ft piece of 2x4, 25mm torx bit socket. Alot of these are your basic tool's that can be bought at sears. Like a craftsman kit.

Parts needed: New valve Cover gasket w/sparkplug tube seals, timing belt (optional, really depends on the mileage your at 50k and below your fine but your call). 2.0l Cams(or what ever cam you choose to install), 2.4l adjustable cam gears(needed to maximize power gain of the cams) Rtv - Black (I used Mopar Atf Rtv works great)

Note: Some of these images will be different than your car. I already had the gears installed along with a 2.0l exhaust cam. I'm going back to do the intake cam this time as well.

Remember take your time with this. Don't rush this job or you will be hating yourself. I cant stress that enough.

Step 1: Disconnect the negative battery cable
Step 2: remove your intake(cold air or stock)
Step 3: Next remove your coil pack and plug wires.
Step 4: Disconnect you injector wires and pcv line. (you do not have to remove the fuel rail or fuel feed line) When done it you should look like this:

Step 5: Remove your valve cover. there are 9 bolts total that hold it down. Just lift up and slide to the driver side to take out.

Step 6: Remove the upper torque arm and mounting bracket. Along with the mounting block on the motor as well. There are 2 18mm bolts that hold the actual braket in place. One is a bolt and the other is a nut. Take those out along with the toque arm itself. Do not disconnect the main portion of the mount from the mounting block on the motor. remove it all as an assembly. Bolts/areas highlighted in red.

Step 7: Disconnect your temp sensor connector just below the thermostat housing.

Step 8: Loosen the 15mm bolt on the alternator. Also back off the 13mm nut so that the alternator can pivot and relieve belt tension. The alternator wont move until the lower pivot bolt is loosen. That will come later.

Step 9: Remove Coolant overflow hose and set it out of the way.

Step 10: Remove upper timing cover. There are 3 bolts in total that hold it in place. The are 8mm. Set the timing cover aside.

At this point your engine bay should look like this:

Step 11: Jack up your car and remove the passenger side tire. Be sure to use jack stand for safety and because you will need your jack later on to support the motor.

Step 12: Now remove the cross member support, and slash shield. There are 4 10mm bolts and 2 push pins that hold the shield in place. Once you get the bolts out just push back on the shield(towards driver side close to where i marked) to release the push pins. When remove the cross member support remove the 2 15mm's. And the 18mm long stud/bolt below the lower 15mm. Not the location of the washer. The engine will move because you now have release all torque struts. Don't be alarmed the motor wont drop.

Step 13: Now remove the lower toque strut completely. Then loosen the 15mm pivot bolt on the lower portion of the alternator. Remove the Serp. Belt via releasing the tensioner by pulling towards the fire wall with a 15mm wrench on the tensioner bolt. Once all belts are removed. Remove the 19mm bolt on the crank pulley.

Step 14: Take your 3 jaw puller and medium extension and insert the extension into the hole where the crank pulley bolt came from. Insert the 3 jaw puller onto the pulley making sure each jaw of the puller is inside the pulley and seated flatly to the pulley surface. If you are not careful you can shred the pulley itself and possibly damage the crank. See images below




Step 15: Remove the lower timing cover. There are 2 or 3 8mm bolts that hold it on. Once that is removed reinstall the 19mm crank pulley bolt to the crank. Do not reinstall the pulley just the bolt. You will need the bolt installed to turn the crank to set TDC.

Step 16: Now its time to remove the power steering pulley. There are 2 ways you can do this. Either A: Remove the intake manifold (the Long way). B: Cheat and squeeze around it. There are 3 bolts that hold it in place. You do not have to remove it from the car completely just remove the 3 mounting bolts and get it out of the way. This can be done from below the car without removing the intake. You will need a 13mm socket with a swivel head/universal joint, and a really long extension or multiple extensions. Remove the highlighted bolts and move the power steering pump out of the way. Note: Be sure to notice the pulley alignment It needs to be aligned correctly on reinstalling it or else you will have a belt squeak when the car warms up One of the three bolts is hidden in the pic. I highlighted the general area it should be in.

Step 17: Now you need to put a jack under the motor. using the 1ft 2x4 Put it on top of the jack surface (as not to damage the oil pan). And jack the motor up. Make sure the piece of 2x4 goes long ways across the whole bottom of the oil pan so as to potentially crack is from stress.

Step 18: once the motor is supported You need to remove the main motor mount bolt. You can access the bolt through the fender well by removing the cover with a small screw driver. Then take a 55mm torx bit socket and remove the motor mount bolt. Depending on how much tension you put on the motor the motor might drop a little. As long as it is supported it wont hit the ground.

Step 19: Now you need to Remove the bolt that hold the motor mount itself in place. There are 4 13mm bolts. With the motor in its natural position remove the bottom 2 bolts of the mount. Then jack the motor up as far as it will go. (take care not to break anything when jacking up the motor. Make sure you do it slowly.) Once the motor is jacked up remove the top two bolts on the motor mount. Once the mount is free to rotate. Rotate it to where the lowest part of the mount is closest to you. It will be the area that is almost flush with the body itself. This is to help ease the removable of the front mounting bracket. You'll see in the image.


Step 20: Once you have the mount in position, its time to remove the front mounting bracket. This part is somewhat of a bitch, so just have patience. It will come out of there. There are 3 15mm bolts that hold it onto the motor. Remove the top one completely. loosen the bottom 2 completely but dont not worry about removing them. There is no way you can without removing the bracket. Not enough clearance between the fender and the bracket. Once you get the bracket loose from the engine now you have to fight. You want to lift it up yet outwards towards the front of the car to get it out. Once you get the front two bolt holes past the timing belt then getting the back one free will be easier. If you crack the back portion of the timing cover thats ok. It wont hurt anything. Just take care not to damage the idler pulley or water pump pulley. You may have to rotate the mount itself around a little to clear it. If you start getting frustrated walk away for a little bit then come back when your calm.

Step 21. Once the Mounting bracket it out, Rotate the crank clockwise to where your timing marks on the gears line up. and the crank is at TDC. There is a little arrow on the crank pulley. Make sure it lines up with the little arrow on the block itself. This is VERY critical and if not done correctly you could fubar the rest of the install. The marks are highlighted in red.


Step: 22: Before removing the timing belt. Loosen the 18mm bolts on the cam gears. Its important you do this before removing the belt so that way you wont turn the cam shaft by itself. Doing so could result in having valve to valve contact and will damage the valves. It easier if you have an impact gun. If not you may have to hold the crank bolt so that the crank doesn't turn instead of loosening the cam bolt. Once loosened make sure you are still line up correctly on your timing marks.

Step 23: You can now remove the timing belt. Take a 13mm wrench and loosen the lock bolt on the tensioner. Then rotate the tensioner plate clockwise to where it is now facing downward. Then remove the timing belt.

Step 24. With the timing belt removed, remove the cam gears from the cam shafts.

Step 25: Now remove the cam shafts. Loosen the cam bearing caps one at a time. but dont remove any from the head untill they are all loose. Once all the caps are loose remove them one at a time taking care NOT to mess up their orientation and order. doing so can result in premature bearing wear on the cam bearing caps and result in a noise and excess metal going through the motor. Set them on a piece of cardboard in the exact order/orientation the came out in. Once they are removed remove the cam shafts themselves.


Now you should have a bare head: Make sure none of the rocker arms fell out of position


Step 26: Now transfer the cam seals and intake cam magnet from your stock cams to the 2.0l cams/Aftermarket Cams.

Step 27: Clean up the head surface with a razor blade. Remove all excess RTV/red sealant from the cam bearing caps and head. Once clean put some black rtv on the 2 cam bearing caps that had the 10mm bolts in it. Anaerobic sealer (the red clear stuff) is the factory sealer and is he best to use. However, using RTV SPARINGLY will get the job done, but it has to be a VERY thin coat of rtv. Otherwise you will affect your cam journal clearances and possibly block oil passages. You can get the Anaerobic stuff from Mopar and is the same stuff that comes with the LSD install kit.



Step 28: Lube up the camshafts with oil on the lobes and bearing surfaces then set the new cams in place. For 2.0l Cams make sure the holes in between the number one cylinder cam lobes and the number 2 cylinder cam lobs are facing up. For aftermarket cams make sure your dowel pins are both facing up or down. Then install the bearing caps. Start from the middle bearing caps on the cams and work your way out untill the cam shaft is fully seated. Do not tighten them as you go. Just seat them down fully. Once the cam is fully seated THEN go back and torque each bolt. For the 8mm bolts torque them to 105 in/lbs. For the 10mm bolts. Toque them to 250 In/lbs


Step 29: Now that your cams are installed, install your cam gears. Make sure your adjustable gears are set to 0 then just snug the bolts down dont try to torque them. TAKE EXTRA CARE NOT TO TURN THE CAMSHAFT! Turning the camshaft one at a time can result in damage to the valves due to valve to valve contact. I cant stress this enough. You can turn the cam slightly for aligning your timing marks but DO NOT make a half to full revolution on the camshaft.

Step 30: Once your timing marks are lined up on the gears. Make sure the crank is still at TDC. If it is then install the timing belt. Once the timing belt is installed Tighten the tensioner. Take a 1/4 inch ratchet and install it in the square hole on the tensioner plate. Turn it to where the timing belt is the tightest and then tighten down the lock bolt on the tensioner. If all goes well you should be perfectly in time. If your timing marks all line up then rotate the crank shaft 2 times clockwise to seat the timing belt and tensioner. Recheck timing after the second turn.

Step 31: Before reinstalling the mounting braket. Take care to remember to grind down the flate area on the back side of it. There is a lip just below the upper area of it where the upper torque arm would mount. That lip is what needs to be dround down a little further. Forgetting to do so will result in the adjustment bolts on the fidanza gears to rub against it.

If all goes well, you should now be ready to reinstall everything. Just reverse the order in which you took everything off and you should be good to go. When installing the crank pulley. You will need to center it up on the crank. Then tap it down with a hammer. Once you are more than half way down then run the crank pulley bolt in to pull the pulley the rest of the way down.

When installing the valve cover. Put dabs of RTV in these six locations


Once you are completely back together Start your motor. If everything was done correctly and your gears are set for 0. Your idle vacuum should be at 20. (May not be the case with aftermarket cams depending on how big you went) If your vacuum is less than 20 and you arn't running a large cam then your cam timing is off by one tooth. Anything more than one tooth and the car wont start (assuming the timing is off in the orientation of the intake came and crank). Once you have verified the car starts and runs and your vacuum is ok. Then you can start adjusting cam timing. It is best to do it on a dyno though. Never go more than one degree increments each time you adjust them.

I hope this helps everyone.
Bryan

Thanks guys.

I wrote this up shortly after finishing my install. Took about 3 to 4 hours to write up. And it was about 4:00am when i was done, so if anyone catchs any mistakes let me know and i'll edit it.

This write up is mostly geared towards 2.0l cams but will work for aftermarket cams as well. Just a few things will be changed.
