Valve cover leak.. I think
Valve cover leak.. I think
So I have a 2000 Honda civic si, b16 and I have a pool of oil what seems to be coming from my valve cover and its leaking right next to the ignition pack. I'm pretty positive it's the gasket but I just need some confirmation from some one that has a little more experience than myself

Got pictures?
All rubber gaskets are suspect. Distributor O ring, valve cover gasket, VTEC seals, etc.

You could clean the area off first and see if any stains come back. For that vintage of car more than one may be leaking.
Mine is a '97 and I replaced the valve cover gasket, spark plug tube seals, valve cover bolt grommets and oil pan gasket and distributor o-ring. Did all this in summer 2014. I remember the old gaskets, they were nowhere near as pliable as the new ones. I tried bending them just a bit and they just cracked and split apart.
I cleaned around everywhere the gasket goes so I could tell if there was a leak after. It's hard to clean around the distributor area with the distributor in place. If you take it off, use a sharpie and mark its position on the bracket so it goes back on in the same place. Also be careful about spinning the distributor shaft when it's off the engine. The end of the distributor shaft is such that it only goes on one way on the end of the camshaft, but some people have managed to force it in the wrong way.
Valve cover is one of the easier ones. Take note of the way the spark plug tube seals go into the recesses and make sure the new ones go in the same way. Also be careful when putting the valve cover back on, you can easily tear the tube seals. This happened to me and I ended up getting a second set of just the tube seals and redid those. When I put the cover on, I put a bit of oil on the inside edge of the seals to help ease the seals over the tubes. You will know when they are all properly through. Then you can tighten the cover bolts to the torque, which isn't much.
The cover bolt grommets are kinda tough to change but it is doable. Use a bit of fresh engine oil to help the grommet get past the bulge on the bolt.
Oil pan gasket isn't that bad, but requires dropping the front exhaust pipe. On mine, I managed to get the 3 nuts off the front flange without breaking anything. At the rear joint, the bolts and nuts had become unrecognizable blobs of rust, so I just cut those off and put new ones on. Hacksaw can work, though angle grinder is very fast. The springs were still reusable. New gasket at each end.
