Thanks for the input Don So you are saying to use the factory rear cap with a original style rear main seal kit.Should use any kind of sealer on the install? I dont have the original 440 rear cap but I do have one from a 383,are they the same? Like I said I do not want to do this again(lol). The shop that did the motor,?first use the factory cap but used rtv instead of side seals,that leaked 20min after first start up,took the engine out and brought back to him,he said I always use rtv and never had a problem(GM lover),this time he put in MP billet rear cap in and it did make it leak a lot less,but after driving this past summer it showed signs of leaking again.So it is my time to do it,I just want to do it correctly. -----Original Message----- From: Don Dulmage <big-d@xxxxxxxxxxxx> To: 1962to1965mopars@xxxxxxxxxx Sent: Sat, 3 Jan 2009 5:51 pm Subject: Re: Rear main seal install RB Take the freaky fancy rear main seal and give it to someone you dont like. Use a normal one. Dress the deal holder a bit on the bottom with a file . Not much , just clean it up. It makes the seal just a tiny bit tighter. I like the cordeco seal best. The funnny stuff will work should you be lucky enought to get it installed but the factory style works perfectly I have found. I used some goofy thing my pal brought inhis engine. Spent half a day installing it. When last freshened the engine he said "you arent going to need a new seal for the billet one are you.?" I said" nope cause I aint using one again." (That bandito! How did he know?) My rule in old age is if it comes in a blister pack then it is probably no good.? Grumpy old Don? ----- Original Message ----- From: "David Raffa" <dge645b@xxxxxxx>?
