I just called an auto parts store to order oil cooling lines for my 1995 GMC Sonoma 4.3FI. They are telling me that there are only two lines, but from my research I have two (inlet and outlet) that run from above oil filter to [engine](/topics-engine-gmc/), and two (in and out) that run from engine to radiator. Am I looking at the wrong thing?

Hi my name is \*\*\*\*\* \*\*\*\*\* I'll be more than happy to assist you. Please allow me a few minutes to review your information. Thank you
Automotive Expert
only 2 lines. (see pic)

Gotcha. So does this run from the engine to radiator or is it the oil filter to engine?
Automotive Expert
is this 2 or 4wd?

2wd
Automotive Expert
ok then from the radiator to the oil cooler (see pic)

Got it. What is the line that runs from above the oil filter? That is where the leak is coming from.
Automotive Expert
is it oil or [coolant](/topics-coolant-gmc/)?

Oil
Automotive Expert
from this pic what line are you talking about?

To be honest, I am not completely sure. I could be talking about something totally different. The only thing that I know for certain is that I got an oil change at a jiffy lube and they told me to check the area above my oil filter because it was leaking oil fairly rapidly. I'm sorry for not having more to go off of.

My best guess is somewhere around the 5,6,8 region.
Automotive Expert
standby please

10-4
Automotive Expert
that would be the oil filter adapter, there's an ORING behind it that has a tendency to leak.

That makes sense. I will look into it.
Automotive Expert
ok, very good. keep me posted.

Just got out from under the truck. I see no signs of leaking from anywhere, especially where it usually came from.
Automotive Expert
is the oil full and did you check it after running the engine for a bit?

The oil level is good, and I waited until the engine cooled.
Automotive Expert
ok well if there isn't a leak, I'm not sure what you need me to do

I was just keeping you posted, per your request...
Automotive Expert
ok. I appreciate that.

No problem. Thank you for the suggestions.
Automotive Expert
did you already replace the lines? or you didn't because you can't see a leak?

I didn't replace anything. My neighbor (a backyard mechanic) took a peek as well and agreed that there is no leak. I'm not sure what happened, but it seems to have magically stopped.
Automotive Expert
did the oil change place show you the leak or just told you ?

They showed. I looked closer when I got home and saw a significant leak. I figured it was the oil filter, so I changed it myself. The leak was still pretty bad, and lasted for about two weeks. Now we are here.
Automotive Expert
hmmmm

The thing that makes it even more weird, my cooling system did the same thing. I went through a four year long process with it and it just stopped leaking one day. I still check the fluids once a day, and it never goes down.
Automotive Expert
if you want to, dump a bottle of Lucas in the crankcase. you would need to drain a quart of oil out though.

Lucas stop leak I assume?
Automotive Expert
it's not stop leak. I never recommend any kind of stop leak. its engine treatment

Gotcha. I’ll give it a try tomorrow!
Automotive Expert
ok sounds good

Still not sure what you need?
