Hello.
I own an all aluminium 482 FE (pond) built by Brent Lykins in 2012 with 13500 miles.
Since weeks I noticed excessive
oil consumption and smokes at start-up.
I've checked all cylinders compression and find 246 psi except on N°2 at 188 psi.
I removed all spark plugs and found
oil on N°2 spark plug.
After disassembling engine I didn't find piston rings broken / no damages on cylinder walls.
==> I'm going to measure all cylinder bores and pistons diameter.
When I removed the intake manifold and cylinder heads I found all intake valves plenty of burned
oil and in intake tunnels.
Some valve seals are worn and I discovered one worn valve guide.
I don't have a PCV valve / just 2 breathers on valve covers.
Questions are:
- if ring gaps of first piston ring (top) and second piston ring are very close (5° to 10° and not 180° as they should be can it be the source of the low compression in N°2 cylinder ?
- how can I get oil in intake tunnels and intake valves in that excess ? not sure it could only be due to a worn valve guide and 3 or 4 worn valve seals....
Here are pictures to illustrate my problem.
Thanks for your help.
