I just replaced my timing chain, oil pan gasket, timing chain gasket, and the front crankcase seal. The problem is I'm now getting a sporadic oil leak from under the pulley. It looks like the front seal is leaking but I'm not sure why. It's leaked about 1 qt in the last 600 miles or so. Anybody got any ideas? <img src="/forums/images/graemlins/scared.gif" alt="" />


You didn't mention anything about pulling the head and replacing the head gasket...so I assume you didn't?

If not, and assuming it's not the front oil seal, then that's the problem. The headgasket seals the top of the timing cover with the bottom of the head. In some cases, you can get away with not removing the head if you RTV up this area, since it's a low pressure area, but otherwise you'll have a slow leak here.

I've had one there for years after I did the timing chain job the "easy" way. After it leaked and I pulled it apart again to fix it, I really bungled the headgasket, so I just said screw it and cut off that part of the headgasket (hate to admit that) then a RTV'd the crud out of it and have been living with a slow leak ever since.

One of these days I'll do something about it. But I say, if it ain't broke, don't fix it. That's why my truck is completely stock. <img src="/forums/images/graemlins/smile.gif" alt="" />
Brian, no I didn't remove the head but I did use some RTV and it doesn't appear to be leaking from there.

That's what's so weird about this leak. Before the timing chain swap it leaked a little around the oil pan but didn't leak at all around the timing chain cover. So I know it was something I did or didn't do.
