Leak down test was done today on my motor with the compression issues, Upon further examination it turned out to be Cylinder 2 with the problem. Valves and all other Cylinders checked out fine. #2 is believed to have a bad ring hence the 90-100 less compression. My question is this: once the motor is torn apart should my tech find that the cylinder bore is not scarred or damaged in #2 can he not just replace the ring's and re-assemble. It's my understanding that the block can only be sleeved and it's not possible to machine the block.
What in the name of god could have caused a bad ring after 14,500 km? I did not do a baseline or compression test on the motor prior to installing an SC. The SC at the dyno showed very conservative A/F ratio's and I'm quite certain that is not the cause.... Any suggestions?
I purchased the car with 8,400km, is it possible that the prior owner did something to cause this? Can driving the **** out of this motor in cold Canadian weather for 6,000km do this? I always waited for it to warm up but still. I'm lost for ideas....
I don't want to build the motor again without correcting a possible problem and having the same thing happen.
Are there things I should look for when torn apart?
If the bore is ****ed should I buy a new OEM block or sleeve it with better pistons?
