I'm putting a new pan gasket on my MKIV BBC w/Milodon pan and using the one piece for the first time. I splooged the silicone gasket on the timing cover with the four piece kit on the last go 'round.:D

On the one piece, no sealant at all on the rails and just a dab at the transition to the front cover and the radius at the rear on both the block and the pan?

If I use RTV at the radius let it set for how long before installing the pan, then how long before full torque? Is there a different torque spec than OEM on the one piece?

I will be vaccum and soap checking before reinstall this time too.:D

If the pan fits well with the rear main cap and timing cover, and the pan rails are flat, you shouldn't need anything more than just a tiny bit at the transitions you mentioned. Just check the fitment in these areas for any issues that may require a little more prior to final assy,

And I'm not a fan of letting the silicone sit before assembling but............

IF I use silicon at all, I only use it between the gasket the block. Never between the gasket and the block
. And I just wait till it skins over. That way I can remove the pan without screwing up the gasket. A "little" grease in the corners between the gasket and the pan can be usefull to help the pan pull into the corners without dirupting the gasket.
Hmmm, Got it!


Thanks, I know what you meant.:D

Good:D Because after re-reading it, I realize it was a little more than screwed up. I perfer not to have any silicone between the gasket and the PAN
Which is right whre I'm blowing a chit load of air from the vacuum pressure test after the new gasket install.:p

My Milodon pans seal for shit, the only pans I have ever had leak. I hate pan leaks, I now glue both sides of the pan gasket with gascinch and silicone the rubber, install pan snug, let set for an hour and finish snuging down the bolts.

Now there's a common denominator.:D

I wanted to try GN's advice with my first time try on the one piece.
I'm just glad there was the thread on the vacuum trick before I power tested it. I do enjoy laying underneath a fully assembled motor on an engine stand.:D

Pressurize the block with a shop vac, a very clean shop vac, then spray a soap solution on the gasket areas and see if it blows a bubble.

I think it looks cool when a guy uses a tube of silicone and smears it all around the outside of the pan/ gasket/ block joint then uses his finger to smooth it.
I'd go with that. :D

What was that trick? Everytime I rebuild i always have a small leak at the rear main seal on my dooley pan....
I have never had great luck using a vaccum to find oil leaks. But turn it around and blow into the motor:)devil all you need is a little liquid soap and water mix (mostly soap, very little water) in a spray bottle, and you'll find right now. Just make sure the vaccum and hose are spotless.
Rat bastard :)Rant

Good side:


Not so good side:


GN7, using the shop vac as a blower worked out great.

I'll pull the pan tomorrow :)st

Those one piece pan gaskets are the hottest thing since sunburn. Removed one on my sons engine three times while dynoing. Still sealed up great and no leaks after a season of racing:(:(
