Hi, I recently bought a 1986 Scirocco Deluxe 1.8 8v 5MT, and when driving it home from the place I purchased it from, had a oil pressure light come on when cruising at 80 km/h. The oil pressure light came on after about 10 minutes of driving, and turned off when I slowed down (30 seconds later, (I didn't pull over because I was near my house)). The engine was rebuilt by the previous owner, and he put a new oil pan on the vehicle (has cooling fins), I'm wondering if the dipstick is applicable with the new oil pan he got. I did an oil change today and about 4.75 quarts came out of the engine, when looking up the recommended amount of oil to put in the engine it was 4 quarts, would this cause a oil pressure issue? I'm also thinking it might be one of the oil pressure sensors, but I came on here to get some suggestions on what it might be.
