Hello everyone, so my 02 Montero Sport with the old 3.0 really leaks oil, it started happening after my mechanic did spark plug change on it 4 months ago, since then, the car drips 4-5 drops of oil on the FLOOR after driving it. The timing belt and valve cover gasket work is done on it less than a year ago, but this is a big oil leak as there are 2-3 drops of oil on the floor just 5 mins after turning it off after a drive. Mainly the leaks are on the passenger side and a couple of them in the middle. What could it be, my mechanic said it could be the Crank and cam seals and to fix it he quoted me 450 bucks! Please advice...

 

My bet is on the valve cover gaskets.

 

Thanks for the reply, I think those were replaced not long ago by my mechanic because don't they kill the Alternator first if they are bad? The alternator has been good but the oil leaks on the ground from the right passenger side after a drive. Whatever it is, I will get it fixed in a week because I have a buyer lined up for it for $2100, I bought it for 2200 2 years ago and put 42000 miles on it since, it now has 208k and timing belt and tune up has been done on it couple months ago. Will enjoy my new 04 Montero Limited I just bought for the next 2-3 years.
