My first guess would be the oil cooler lines, yes.

Oil cooler lines are on the passenger side. Engine oil leak on the driver side possibilities: fill cap, pcv hose, valve cover gasket, head gasket. Get a jack and a flashlight – no reason to need a lift to trace down an oil leak.

I went back and pulled the notes from my first one and that was one of the track failures.

The sender is on the passenger side i believe. The oil pressure relief valve is located on the right side of the timing cover though. You’re positive it’s oil and not power steering fluid right? The power steering line is a more common leak in that area.

Will poke around tonight and report back. My 57 Cadillac took a huge oil dump on the floor a few weeks back when a cooler line finely let out so it seems par for the course. Waiting for one of the other cars to start leaking as well.

Could still be the cooler lines – oil has a super fun habit of running all over the place before it finally arrives on the ground 😉

oil lines….

Kind of in a bind I have some track time in two weeks and my ACR decided to start piddling all over the garage floor. I would really like to not leak all over the track or blow a line.I have a leak about 4 tablespoons of so a week on the garage floor and only after running the car, only happens when the motor is hot. It looks to be happening near the driver side engine mount and then rolling back towards the exhaust and starting to burn off there. Is this the dreaded oil return line failure or is it something else. I remember on my last one that I had the lines upgraded but the leak was more towards the transmission bell-housing.
Is there some sensor in that area that could be leaking. Any idea's. I cannot get it on a lift till next weekend and if its something like the lines I would like to order them now to save on time.

OK anybody got a photo of a ACR up on a lift from underneath the car. It almost looks like it is leaking form the pan and oil drain area and getting blown up into the car.
But on the oil pan next to the factory oil drain plug on my pan it looks like there is a patch. Its a piece of metal, its not welded ni place that sticks out and has some crosshatch on it near the part number stamping. Its really odd.
Oil is on the lower suspension mount for the front driver side and no further forward. I got a bit that is near my shock remote resivours which are tuncked in near the rear of the driver wheel as well. But there is dripping oil on the pan itself.

Ok Oil leak kind of found, got it up on a lift, thought that it was leaking form the pan but looks like that is not the case. Power washed the oil off and went for a quick drive.
Its on the driver side of the car in this area.
So right near the from bolt on the header next to the big AA there is definitely some oil. might have been blown up the big compresser underneath is dripping with it.
Freshly cleaned floor straight down and there is the drip on the floor. So it must be coming from near the head and the header right?

Feeling very very dumb right now are the valve covers on this car decorative or actual valve covers because every single bolt on the driver side was backed out and ever single bolt on the drivers side and not the passenger. Sssuming like 10lb’s on the torque wrench.
