A couple of weeks ago I changed out my clutch. Had an oil leak, which was for sure intake, but wanted to replace the rear main while I was in there. AT the same time I tore the intake off the car and put in a new gasket, sealant..etc.

To get the old rear main out, I just pried it out with a screwdriver. Unfortunately I didn't pay much attention to how far the seal was pressed in. To get the new seal in, I got it started by hand and with a feeler gauge made sure the seal was in right, and tapped it in with my snap on hammer which has a plastic beater.

Well, Now I went to the track (road course) and I am running mobil 1 10 w 30. Noticed that I have a leak. Looks like is coming out around the bell housing. Took off the inspection cover and there was a drop of oil on the crankshaft where the flywheel connects.

The top of the engine seemed dry. SO looks like I now have a rear main leak. I will fix it again, but what can I do to make sure I don't mess it up again? I felt pretty good about the way the seal went in last time.

thanks for any advice

Are you sure it is not the tranny input seal that is leaking? Just checking because I have had both crap out on me. Leaky seals have cost me a lot of misery and money.

 

Not sure but it looks like oil. I will keep that in mind though thanks.

LEaky seals really suck. One of my other rides is a 68 firebird, I put a pontiac 455 in it which is notorious for leaky rear main. I put a special seal in it and have been lucky so far, but this LT1 likes to leak. Not alot but just drip, drip, enought to make a mess.
