Re: still ticking (archive)

I adjusted the valves today, 5 were above .008. I also tightened the exhaust manifold to the down pipe, which was loose. I still get ticking and it doesn't seem to have changed much. The oil is fairly clean still, I had an oil change about 300 miles into the rebuild and another at 1400. The engine was rebuilt about 1700 miles ago. My rings have not seated yet, I think, because it smokes when the revs get up there on deaccelaration. The mechanic said it was the vacum sucking oil past the rings. I had the head reworked about 50 miles before I parked the car for the rebuild. Could I have a problem with the rings, broken or something? Do I check this with a compression gauge? Any answers welcome. Thanks in advance.

Did you adjust your valves cold, as in let the car sit overnight and then adjust them? If your engine smokes on decel, I would suspect the oil is getting past the valve seals due to worn or loose valve guides. Oil could be getting past the rings only if not seated in. You can determine if the rings are to blame by doing a leak down test. This is done by adding compressed air into the cylinder and then listening in the intake or exhaust or crankcase for air leakage. This will determine where your leak is at.
