Rear main seal leak is at this stage mostly cosmetic for the floor. Personally, I would not plan to have it addressed unless something else forces your hand to access it.
Agree. I'm still weighing my options. So far I went to 3 repair shops. Each opened their books to find out the average amount of time it takes to replace rear main seal on a 2001 Lexus RX300 AWD. The results were - 11 hrs ($1500), 16hrs ($2300) and 7 hrs ($700).
Maybe I'll just get a cardboard box ($free) and stick it under car to catch leaking oil and fuhgetbouit.
The leak slowed significantly, almost to a stop. I have not done anything. But my buddy (a car mechanic) told me that sometimes when there's a leak related to the crankcase seal - check the PCV. He said if the PCV is old, it can get clogged then increases the pressure causing oil to leak out thru the seals. In any case, I replaced the existing old PCV. The old one was greasy and dirty and hardly made rattling sound when shaken. I will monitor area for anymore leaks. I hope this resolves the rear main seal leak issue or non-issue. Red top is the new genuine Lexus part. Black top is the existing old dirty PCV.
My 01 RX 300 just started leaking from that same exact spot at 172k miles and I'm not much of a car guy and don't know what to do, idk if u still get on here or not since this was like 5 years ago but If you happen to see this could you please respond to jcorbin2021@gmal.com thanks man
Sorry for the late reply but yes it stopped after I replaced the pcv valve. You should try replacing yours and see if your leak stops. The pcv are not expensive to replace. Good luck.
