I have a 1998 chevy blazer that I bought recently and noticed it has an oil leak, but I dont know where its coming from. I took it to a shop and they said they couldnt see where its leaking, and all they could do is run a few tests for like 150 dollars. So I was wondering if anyone could help me out...... thx

 

take it to the car wash, spray and re check

 

ok thanks i will have to try that, i thought it was the oil pan gasket, but i couldn't find any oil leaks there, so i was wondering if it was the main seal leaking...

 

Sounds to me they just want your money!!!! $150? Jesus I can only imagine what they'll want once they find it....

 

Soo u noticed it's leaking just not sure where? Is it 4wd? If so, a very common problem is the oil cooler lines.......surely u know of the general area right??

 

maybe the previous owner did a sloppy job on the lower intake manifold gaskets.
that's where mine was leaking from. My mechanic couldnt find the leak either with just a quick inspection. you going to have to crawl under the blazer with a flashlight and see how high up you can see the oil.
It would be leaking from the back of the gasket by the distributor

 

Yeah I have been under it and found out where its leaking and it looking like the oil lines are bad, the condom looking thing on the line is pretty bad. Im gonna have to replace them, is it hard and is it exspensive?

 

its not that hard,just messy.
make sure you get the ac delco lines, not the aftermarket junk
they cost around 80 bucks
you will need a 20 inch long extension to get a socket onto the bolt
on the engine side

i read that some guys eliminate the whole oil cooler system all together
and where the lines go into the block will put a adapter
for a oil filter there.
i will do that myself if next time happens again.

 

It's not that bad.....get u a block of wood and a jack to raise the motor up so u can pull the lines out, otherwise they will get hung up on the motor mount!!!!! btw., do a search I personally would just go have u a couple of high pressure lines made up and cut the aluminum lines where they are crimped .....then just put the replacement lines on and clamp them down!!! I ended up using the aftermarket onewell I already replaced them once, next time I'm gonna cut the rubber lines off and have some high pressure hydraulic lines made to replace them.........

 

^^ Yup, been there, did that, no more leaks. Aftermarket and OEM lines are not the answer, they will leak again, guaranteed. Cut the old aluminum crimps off, (not the aluminum tube) and use compression fittings and hydraulic line. Good to 3000psi... plenty good for 80psi of oil pressure Cost about $60.
