The first step is to check the compression. Also do a leakdown test. You can tell a lot based on these results. You may just have a ring or valve problem (best case). You'll of course need to know why which will take a bunch more disassembly and digging. There is also the possibility of a broken piston cooling jet. This causes oil to build up in the sump and creates all kinds of issues. You can check for oil in the sump by pulling the crank sensor and looking down in the hole or by removing the case drain plug and noting how much oil comes out. Anything more than a few ounces indicates a problem. This can be a very expensive problem to fix so let's hope it isn't that. I hope this helps. Please let me know if I can be of further assistance. Thanks, P.J.
