Noticed huge oil leak sigh...

Featured Replies

So car is driving great and all but I do not like to see drops of oil in my driveway. If i look below i usually see a tiny bit of oil on the front of the oil pan. Now I see so much oil that the driver side control arm is coated in oil and the whole rack and crossmember look to be completely covered in oil hmmmmm. Recently weather has been -20C without windchill. Possibly started leaking large amounts when cold then once warmed up stops leaking? I will try and role myself under the car although any possible theories?

 

It's a 94 legacy turbo. Replaced valve cover gaskets, and rear cam support gaskets. Everything else left at w/e the previous owner left it. Plan for spring timing belt, pump, cam, crank, oil pump seals.

Your spring reseal should take care of it.

Not much to leak on the drivers side except the valve cover gasket or the front cam seal.

 

Automatic transmission? The cooler lines run on the drivers side and they could be leaking. You could check the levels in the auto tranny (not the front diff) and the power steering to see if they're the culprit.

 

On the turbo cars the oil drain hose from the turbo back to the head can start leaking, but that would be on the passenger side.

Thanks for the replies, definitely see oil from the timing covers and I guess when driving down the highway for hours it was dripping along a bunch of things. It appears I overfilled my oil alot. Possibly creating a issue? Going to drain a bit of oil, then do a oil change when it gets warmer. Rotella T 5w-40 was amazing oil this gtx crap sucks on cold starts it loud engine doesn't sound nearly as happy as it did on 5w-40 synthetic.

How overfilled? Half a liter? Liters?

 

One other thing to check is your PCV valve. Replacing it with a subaru one can help if it hasn't been done in recent memory. Check the tube that leads up to it. Make sure you can see down into the pipe going into the block by the bellhousing. They get carboned up sometimes and a good cleaning can help a lot.

 

If the PCV system isn't working properly, the positive pressure in the crankcase can push oil past seals it wouldn't otherwise.

Well heres a update started car and noticed oil dripping steady. Turns out when I swapped the drivetrain forgot to tighten the clamps for the cooler lines and was dripping down the crossmember. Tighened clamps washed oil underneath. Seems good but there is still a oil leak. I did a oil change motor sounds better. Less oil leaks too I hope with 5w-40. Will check out that pcv valve since the motor did sit for a bit. Thanks!
