Hello all. I've got an 85 1.6L Golf. She's losing oil at an alarming rate. I drive 120 miles a day at 65 mph. The back of the car is covered with a black oily substance, which i'm assuming is oil, since my dad's diesel golf (identical to mine) doens't do that, so i know its not diesel fuel. I'm going thru at least a quart a day. Any idea what i need to fix. Valve seals maybe? Or is my motor gone? Thanks for any help!

compression check, and then leak down test.
You are refering to the very back of your car being covered in oil, not the firewall correct?

Yes, the back of the car is oily. I'm not familiar with a leak down test.

Does it appear to be coming out the tail pipe or from under the car?
You can have a leak from the engine and still get oil all over the rear of the car.
Does it leave a puddle when you park?

Consumption that high usually means worn rings/cylinders. My pickup used about 2-3 qts every 400-500 miles and the rings were roasted. I suspect you're in the same boat.
I'd pull the crankcase breather tube, and check for heavy blowby and/or white smoke puffing out of the tube. If you have one, the other, or both, then you're probably looking at a rebuild.

Yes. I hadn't checked before, but the whole underside of the car is coated in oil.

there are a lot of gaskets that can leak, I wash my engine to locate them more easily.

oil dipstick usually leaks a lot when it goes, other then that there is all the crank/cam seals and the VC gasket. Upgrade to a rubber one if it is leaking

b_y_$, when you say dipstick, do you mean at the top where you pull it out, or down in the pan?
Supposedely, when i had the IP pump done, the valve cover gasket was replaced as well.

down where it meets the block, it should have a oring. when that fails ( common) lots of oil is lost.

that's the one I meant.
Losing that much oil it should be easy to find. Pressure wash the engine and top up the oil and just sit there reving it from the engine bay.
