Sealant for doing oil pan?

[Booster]

Ok - Ive removed all that crap before so I am going to go that route. Jacking up the motor/dropping subframe just sounds... not fun.

I have a full tube of Permatex Hi Temp RTV Silicone Red "GASKET MAKER" I checked their website, doesn't mention sensor safe. Hrm, think its good to use?

Also - should I let the RTV, should I use it, fully cure (who know show long that'd take?!) or is it ok to drive maybe ~ 1 hr or so after installation.

It'll say on the new tube of Permatex Jon. I usually wait overnite (4-hours min.) .
As far as going with out it.....I would definatly use some at LEAST at the points Bill R has indicated .
Your car will be seeing elevated engine bay temps and the temp of the oil will be higher than norn too.....the thin viscocity of oil will find a leak.......just drop at a time makes a mess in NO time when parked on a nice clean floor.
SEAL IT....top and bottom thinly, your choice.

Thanks so much guys. I will stop and get a tube of the one you mention Bill. Unfortunately I will have to drive the car afterwards, but it wont be until after the pan is back up to the block, everything straightened up, and we lift the head out of an E30 S52 turbo we're working on, so I should have a decent "dry" time. thanks again.

i ended up using permatex black. its sticky as hell, i doubt it will leak even if i take all the bolts out.
