I have already changed the crankcase unit last year.
Now I see oil leaks from the timing cover and/ rear main seal.
( I went to the dealer, and the dealer said change the head gasket which is $5000 in repair) .
what should I do next?
IMy car leaks as you move car and after driving I can smell burnt oil and leaks on ground
oil coming out of the oil cap
Oil leaking from throttlebody
oil was leaking mostly showing up around throttle body. Having to add oil regularly which I had not been doing. Mechanic said too much crankcase pressure even though I have pcv update. Checked and cleaned out oil separator which he said was stopped up and it seems oil leaks have stopped.
Leaking oil when driving from front passenger side..
leaking front passenger side of engine. had the timing chain seal replaced. kept leaking, mechanic said it was over filled with oil--blowing out ventilation pipe
leaking near timing chain tensioner. had seal replaced and still leaking
Went to get my oil done and they said they couldn't service me because there was a oil leak and it's blowing white smoke when I got home there was no oil it was bone dry
oil leak around oil pan
Started noticing oil level drop at a faster rate. Started adding oil every 3 to 4 weeks. Under carriage was checked and saw oil across the bottom of engine, but no leaks on top or sides of engine. Can you perform a color test , change color of oil to see where leak is.

Bad oil leak front passenger side and have replaced the serpentine belt 4 times
After serpentine belt slipped off I noticed that it was saturated in oil. Had timing cover and oil pan gaskets replaced, but problem persists.
