csufdrew · 11-24-2012, 06:11 PM

160-162 across the board.fully warmed up engine and throttle open.

How does that rank? I do have a slight leak from the valve cover gasket in cylinders 2-3. I'm getting my timing belt changed next week and also gonna do the valve cover gasket

Did mine right at 100k. 165 across the board. Leak down was 7% in each cylinder.

csufdrew · 11-24-2012, 07:53 PM

What tools are needed for a leakdown test?

Advans · 11-24-2012, 08:01 PM

Compressor, leak down testing kit...think that's it.

Been a while.

And your numbers are.

csufdrew - there's your reason for a healthy engine right there - oil changes and no overheating I'll bet

This is why I tell everyone general maintenance and fixing shit that's broke goes a very long way.

Worth checking turbo shaft play

If you can just get people you know or friends, etc - to just get the oil changed - they'll end up saving so much time, money and headaches.

Even sending people to Jiffy Lube (or similar) is better than no oil changes. The J-team idiots will often check air filters and things - at least to prevent a disaster - but otherwise they techs are often full of horsesh**.

And when you tell people about something, they can act on it or ignore it!

Correct. Oil analysis actually says to try 9-10k between changes. Also have had 180* thermostat for a long time.
