I did a compression and leakage test yesterday and this is what i got for my results.ca18det240hatch wrote:i wanna know what you get for compression lol, and your break-in technique
1. 125-130psi2. 130-135psi3. 130-135psi4. 125-130psi
Now this was done with the engine cold. I also havent driven the car or used the engine very long so im pretty sure these numbers will go up as everything starts to wear in a little. Once the piston rings heat up and expand i should get better results.
As far as the leakage test, usually you want to see somewhere in the 15-20% area. My percentage exceeded this for each cylinder. I had to use a ratchet and socket to hold the crankshaft from moving and each time the gauge kept going down past 20, 15, 10 even 5% when i did this. Im happy with the results so this is good for now. Ill recheck both of these within a few months.
Now my only problem right now is that damn intake manifold gasket! Im talking about the one that goes in between the head and the sub-manifol! I thought i had fixed my problem by tightening all the bolts real good but apparently it wasnt good enough. I didnt have the vacuum leak but i still have the coolant leak right by the thermostat housing. The leak is from the one and only coolan passage in the manifold and it sucks that im going to have to remove everything just to replace that gasket! This time im going to make sure everything is tight, flat and maybe use a little bit of gasket sealer to help out. I doubt my surfaces are warped but ill check it once i disassemble it.
Another thing im going to have to find are some power steering lines because it looks like mine are done for. Im getting oil all over the place!
