The most common but most unrecognized oil leak - ZR-1 Net Registry Forums

MuRCieLaGo · 06-09-2021

This job is a major pain. I discovered oil pretty much all over the place on the ground this morning (especially from passenger side). I tried to access the 2 bolts from above, underneath, from the side... A big hour later, no luck. I had to remove my headers to tighten them with my (left!!) hand. I've got no clue how you do this without removing your exhaust manifold.

Now the car is out of order until I get a new exhaust manifold gasket.

I run the OBX headers but I can get to the bolt closest to me on that cover. On the one furthest away, I happen to have my rack out for service anyway so I was able to reach in through the front to tighten it.
