On my timing gear thread I alluded to needing to do some work on my engine. This is the 383 I put together and got on the road in the summer of 2022, just two and a half years ago.
It has been going through oil at a rapid rate. I had some pan leakage early on, but even with that resolved I and going through too much oil.
The engine is losing oil, but not showing high amount of white smoke. The exhaust tips do show the evidence.
This past weekend I decided to do a compression check (I know a leak-down test would be better), but what I have on hand is compression only.
All 8 cylinders come in between 180+ to 190-. Easily within the 10% range across the eight cylinders.
With the dead cranking while doing the test (fuel line and coil disconnected for the test) when I fired it up after testing I was blowing clouds of white smoke. It took some running but it did clear up.
I am thinking that oil build-up in the cylinders would more likely have come from the valve seals above as opposed to up through the rings from the bottom.
Any opinions on this conclusion?
