Did the cylinder leak down test and got the following results (bought the tool from harbor freight).
Air compressor pressure out was at 80psi
The pressure guage on the tool seemed to be at a constant 25-28psi
The loss guage showed the following:
Cylinder 1 - 3%
Cylinder 2 - 5%
Cylinder 3 - 2%
Cylinder 4 - 1%
Cylinder 5 - 7%
Cylinder 6 - 1%
Seems pretty good for a car with 92k but would like to make sure that I did this right before I celebrate. Here's what I did:
Removed the coils,
loosened the plugs and re-tightened them just enough,
re-installed the coils without the bolts,
warmed up the car to operating temp,
disconnected the battery,
removed the coils and plugs,
set the engine at TDC and locked it,
started test with cylinder 6 and moved up.
The tool instructions says to leave the oil dip stick and coolant cap out. I did hear a faint hiss thru the dip stick hole but the coolant fill hole was quiet.
I did have to rotate the engine 360 for cylinder 4, 3, 2 & 1. Otherwise the pressure wouldn't hold. The instructions by Wayne are for a 911 so I hope the above is how it needs to be done.
I could not hear any leaks on the exhaust either. I didnt have access to the top side but no audible noise that I could tell.
Could the experts please chime in? Appreciate any comments. thanks
