Here's an update on my smoking problem.
Recap - Blue smoke at idle and low speed. Disappears at higher throttle.
I ordered a leak down tester, which arrived today. I bought a cheapo unit from Harbor Freight, and leaned once again that you get what you pay for. The thing simply would not calibrate or give anything even remotely resembling consistent results. I'm sending it back tomorrow.
I did go ahead and pressurize each cylinder and listen for air leaks all the same. What I discovered was that all cylinders exhibit leakage through the rings. I assume some leakage would be normal, especially considering I performed all testing with the engine cold.
None of the cylinders exhibited leakage into the coolant (no sound at the radiator cap).
None of the cylinders exhibited leakage through the intake valves.
Cylinder 1 had significant leakage through the exhaust valve (listening at the tail pipe). All other cylinders exhibited no leakage through the exhaust valve.
I made sure each cylinder was at TDC with valves closed for each test.
Could this be my problem? I assume that for oil to actually get in there that it would have to be a problem with the valve guide and or seal, and not a burned valve. Is this correct?
