Hey dude, it's me again. Well i think i've had enough with this continual problem. I took my car to a shop to do the leak down test and i really feel that they did'nt even do it. When i picked the car up, the mechanic told me that the problem was the rings. He proved this to me by showing me the black carbon buildup from the inside of the mufflers. I asked if he had done the leak down test and what he found from that, and he said he didn't find anything, but that it was the rings on the drivers side of motor. If in fact he had done the test, i believe he should have been able to not only tell me if the problem was the valves or the rings, but which valves and or rings were bad, correct! I called one of my tech sources to get a final word before i began my disassembly and they said to take the car out on a empty road and leave the car in first gear, bring the RPM's to 5000 and let it come back down on its own. They said to do this six times. With pleasure i did it ten times and i rechecked the compression and it had gone down rather than up on two of the cylinders. The sparkplugs were dry but the compression sucked, so i did it again. The second time around the compression got better from 110psi to 125psi. I'm still not satisfied with it seeming to get better because the next day i started it up and just like before, the same three plugs on the same cylinders were wet with oil and it still smoked like crazy in park. I have made my decision to tear motor down, rehone block, replace rings with file-to-fit cast or plasma moly type rings, new rod bearings,do some port work on intake, port and polish heads. I don't know if i should put a HV oil pump, the new pump i have works well, but i hear many people use them. I have a 7 qrt deep sump pan, but i'm afraid the HV pump will cause more problems like filling the valvecovers with too much oil and cause other problems, what do you think, stay with new stock pump, or go to HV. By the way is my compression in normal range (130psi). The cam profile is int/exh @ .50 214/224 sae duration 292/302, cam lift 295/310, valve lift 510/536, lobe center 107/117. what do you think of the cam i'm using, is there an better one you know of for both torque and hp? Thanks really for all your help, i appreciate it very much.
