Fixed my leak!!
I had a leak around the front of the oil pan where the timing chain cover and oil pan meet. I knew it leaked but I didn't think it was that bad. I found out how bad it was on my last board meet trip. It blew oil all over the underside of my truck all over my exhaust everything. It was blowing it out bad enough at the end of the way back there wasn't a signal car that would get behind me.
So I cleaned up the underside the best I could with a pressure washer. It did an okay job but most of it got baked on. I bought a new one piece oil pan gasket again (felpro). Dropped the oil pan, cleaned it out and the bottom of the engine. The thing I didn't do the last couple of times is use silicone in the corners of the timing chain / block area and the rear main. It seemed to work so far no leaks. I hope that fixes it I've tried plenty of times to fix it before with different gaskets, oil pans and they didn't fix the leak. Next would have been timing chain cover if this didn't work. Just wanted to share with everyone. Feels pretty good to finally fix something that has been such a pain in the past.

Yeah the directions do tell you about the silicone and where to use it. I look at the directions but mostly just a glance over. Most times there isn't anything really important on them and its self explanatory like valve cover gaskets on most things like gaskets atleast. I have also seen where a lot of others haven't had any problem not using any silicone but everything isn't the same.

i had the same leak a couple of years back. i just swapped my timing cover for a chrome one and trimmed the little tabs off at the bottom of the cover. i loaded the corners up with silicone and haven't ever had a leak since.

That oily mess under the hood I used simple green in a garden sprayer and let sit for a hour then sprayed it clean . Who needs directions when you got us here on the board. |

Its weeping now on the passenger side. Not near as bad as it was but I think its the timing chain cover. On the bottom where the oil pan gasket sits is maybe a little to wide. It a stock timing chain cover like 76-77 same as the block. Canton Racing has what looks to be a pretty good replacement for like 25.00.
I like simple green too pretty good stuff. Knew it had to be to good to be true..

I cant say I fixed but I tightened the 1/2 bolts in front. Passenger side was loose and I couldn't get a good grip on it before, this time I got it real good. Had to get the right combinations of extensions and the swivel. Drove it around the block a few times and I don't see anymore oil on the pan.
