Guys- need your opinions with oil leaks on my fleet of Toyotas! I just sealed the valve covers on my 97 4-Runner- both sides were pissing oil. Turned out to be a fairly easy job! Cleaning the motor from top to bottom, I have noticed oil leaks from my oil cooler, oil pan, rear main seal, and various other points on the block. The truck only has 190,000 miles. Still runs very strong! I also have a 2000 Prerunner, and a 95 Camry- both have similar oil leaks in the same basic places. Is this normal for Toyotas? My Camry has only 88,000 original miles and the valve covers are also pissing oil. Installed new valve cover gaskets in my Prerunner as well. Local Advanced stocks all the seals so this to me indicates it is a common problem. I also have two Honda Pilots, both with just over 100K miles and both of them have zero oil leaks. I also have a 1990 Mustang with over 300K miles (5.0) with very few leaks- mainly the rear main seal...Why so many leaks with my Toyotas? Thanks!

 

No not really!!

I could understand if they might have sat unused for years .

Then it could be the weather where you live but I really doubt it.

just your luck.

 

Sealed the rear cam plugs on the back of each cylinder head as well as each valve cover- this stopped the the leaks from going on to each header- Oil is still pooling on the bottom of the exhaust shield that covers the exhaust pipe going from the drivers side header to the passenger side then to the rear of my truck- where else can oil leak from the rear of the motor? freeze plugs? or the gasket between the head and the block?? Any idea??

 

They are old cars. Some old cars leak from their gaskets, others don't from my personal experience.

Fix the leaks and drive on.
