Today I tried to finish up reinstalling my roller rockers after re checking the lash and realizing that cyliners 6 and 3 weren't shutting the valves all the way. After realizing how much of a ***** it is adjusting rockers with the lower intake on I decided to go and try and make my life a little easier.
Went and picked up a compression tester at Sears. Came home and was excited to finsih up, follwed the directions in the haynes manual for a compression test, and what I found made me want to leap off a very tall building.
Three of my cylinders wont build compression over 60psi and they are nowhere near each other. Cylinder 3 is at 45, 6 is at 30, and 4 is at 60. I loosened the rockers on those cylinders and retested only to get the same results. So I did what the manual said and troubleshot for a bit. After pouring a little oil in the defective cylinders compression built slightly but not nearly enough.
Does this mean my rings are shot?
Thats what I get for dissassembling it and letting it sit through PA's winter without the heads on it...
So if this does mean my rings are shot, I'd like to know what my options are right now. Im going to have it professionally fixed, I'm done screwing with this thing, it has fought me the whole way and this is the icing on the cake...
SO, is it possible, to pick up a new set of gapless rings and a bearing set and reuse my old rotating assembly. Or would I need to replace the pistons and crank. My car has only 48k miles on it and I didn't ever really beat on it too much. I don't want to overbore the block if I don't have to, and it's to my understanding that a surface hone will renew the cylinder walls without taking off too much material.
So if I had the motor pulled apart, honed, and reassembled professionally, do you think I would build the compression I need without new pistons and a crank?
Sorry for the length, I'm a little emotional right now. Thanks for your help guys.
