how to check if you block is cracked?

hey all as some of you may know I have not been able to fully drive my srt since may of this year due to a warped head, and blown gasket.... but after I rebuilt the motor(forged pistons , arp bolts , resurfaced head w/Port & polish) I bought a first run SCE NON-TITAN ICS gasket, and as I know plenty on cars this was my first self applied sealant head gasket install... so I may of made a mistake on how much sealant i put on , or what not... but oil & coolant were still mixing.... now since the car has been reassembled I think the car has only been able to run a total of maybe 2-3 days..... so a vendor had mentioned that it could possibly be a cracked block(which I hope its not since you cant buy a bare block from mopar you have to buy a short block for around 1500shipped from MPSC) I'm just wondering what are a few ways that I could check and know if there was a crack in the block?

and to all that like to answer with this "I have used the search feature",lol
thanks for all the help...-James-

If you remove the engine, disassemble it, and take the block to a real speed shop, they will know where to take it to have it magnafluxed... If you can't find anyone up there, we can do it for you down here...

Stick with the OEM multi-layer gasket in the future, it moves with the head pretty well...

Magnaflux or dye penetrant are your options to find a crack. As stated above you'll have to tear the engine down to perform the test.

We use either depending on the metal we are testing. We test mostly austenitic stainless steel so the dye penetrant test is used.

A lot of machine shops can also pressure test blocks and heads for leaks, v-8s at least. Have you checked to make sure the block deck and head surface are both flat? Maybe it wasn't machined properly; it's easy to check.

if you're using a non-titan headgasket are you using an O ring ?

cracked block ??what happened before that made you rebuilt the motor ? Was the motor running good and you just did the rebuilt as an upgrade or did the motor at anytime overheat or knock badly ?

Was the head cheaked to be flat and was the block decked of checked as well ?

Help me see the full picture and I may be able to help you out .

well, first off no I havent done a leakdown, mainly because its been pretty cold here in illinois(i dont have a garage) and it has been snowing... so that ruined any real aspects to get it all checked...

as far as the head I'm pretty sure it was/is flat I had the head done by Nick at NRGY so I'm sure the utmost care went into my head before it was returned.....

I'm gonna be relocating the car to a friends garage in the next few days.. where I will have access to a cherry picker..and such ... but thanks for all the support guys.....

and just so you all know the car would idle fine,temp was fine,only till I would go into boost which I only did 3 times, once I'd go into boost the temp would start to rise, so does anyone have any ideas on what else it could be?

I'm sure that Nick took great care in doing your head but that does not mean 100% that it was checked , but lets just say that the head was indeed checked and its ok . So I'll ask again are you using an O ring in your engine build ? If not thats your problem !!! The head will not seal without an O ring or if its not on right and that will be more evident when you boost and the car heats up .

That head was definitely milled flat while it was here. If I recall correctly it had to have .008" taken off to get it straight again.

Thanks for posting Nick that takes that out the basket !

So if that the case then we're looking at the head no being installed right or gasket failure due to 1 : improper install of the gasket . 2 : the gasket is unable to make a seal due the to lack of an O ring .

Thats said , theres still a chance the block may need to be decked but that will be unlikely if the engine has not been driven much after the rebuild .

which is normal procedure anyway...when dealing with professionals of course.
i'm sure you can get a '15 min. special' head port job for much less these days where stuff like that would be overlooked...but you won't get that with people who take pride in their work.

PS. if it ends up the motor's toast, i can hook you up...

thanks nick and frank.....I appriciate all the help.... and just so you know I worked out a deal with steve at sce, and currently have a new SCE ICS titan sitting waiting to be installed... no I did not have the block O-ringed, cause I was told it was not necessary.....

and to get the origion of the rebuild out of the way, I was working on my car and a friends car at the same time (boostedR/T)on here and I asked him to top off my coolant since he was doing his... and apparently he topped mine off then topped his off, and forgot to put the radiator cap on all the way(like one turn, but not locked so it could pressurise... and we took his car for a test drive then mine, once it heated up it was evident something was wrong so when I popped the hood the first thing I noticed was the steam and coolant coming out of the cap, and I asked him if he double clicked the cap.. well he said he must of forgot after he topped it and closed my hood without doing so....so after that day the car was starting to overheat , so once I figured it was a headgasket I just figured I would do a complete rebuild while I had the head off..... so I now have a ICS titan .. and I'm sure that will remedy the problem.....but none the less the peace of mind that you all are giving me is helping me alot.... thanks all for responding to my post...-James-
