leaky cam cover

My 1.6TD is mounted at the stock 55degs. The cam cover leaks oil making a mess wherever I go. I've replaced the cork and rubber gaskets with the one piece rubber one but the oil continues to drip out. Can anyone help me?

Sure it's not the oil fill cap?
Those gaskets get brittle.

Could also be the valve cover was over tightened and is slightly warped, not allowing the sealing surfaces to seal.

Very good chance of this. The cover leaks over the years, people tighten up the nuts to the point that the cover and tension bars get so warped that replacing the gasket does nothing. Take the cover off flatten it and the bars. Place a little silicone at the corners of the half round seal [the long thin one] .Also make sure the 8 studs are tightened all the way into the head.

I just finally used a gasket sealant to avoid this problem.. Seems to be holding.

This has been talked about quite a bit. My personal opinion is to use Yamabond #4 or equiv, but only on the cam end plugs and only if they are new. If they are removed for any reason or otherwise come loose during disassembly, don't bother reusing an old hardened piece of rubber because it will leak again every time. It may be a day or a year, but they will never seal. On the gasket, put it on dry and it can be reused indefinately.
