if you only move the trans a few inches you can see back there and findout.sorry for your problems.
puff baby powder back there and it will stick to the oil and show a path.use a merror to see if you have to.

Re: MAS. OIL LEAK, LAST TIME IM ASKING PLEASE HELP!!! - 02/22/11 01:50 AM

If you have narrowed it down to the back of the engine, then about all you can do at this point is to pull the engine or trans at this stage of the game and see whats up. 4 times on a rear seal, either everybody is doing something wrong or your looking in the wrong spot. Does it pour out just idleing or under load?

There are alot of things that people can be helped with over the internet, unfortunatly disassembling your car to diagnose it for you isn't one of them. If I had the choice, most times its easier to pull the trans IMO.

Re: MAS. OIL LEAK, LAST TIME IM ASKING PLEASE HELP!!! - 02/22/11 02:26 AM

1. you have a large burr or scratch on crank 2. cam or oil plugs not tight 3. intake gasket not sealed 4. valve cover gasket is leaking. You have to check out all these things even if you have to pull the transmisson

If it has oil pressure I don't think it has any oil plugs loose.

a friend of mine fought one for a while kept changing the rear main seal. It ended up being a crack in the crank shaft.

Can't resally go along with that. Every time a plus was loose or oil was pouring out, never had more than 30 PSI and would not go up with RPM.

Re: MAS. OIL LEAK, LAST TIME IM ASKING PLEASE HELP!!! - 02/22/11 04:25 AM

This sounds veery similar to an oil leak Scott and I fought with earlier this winter. We tried 4 difernt seals (different brands) and 3 different retainers (one being billet) and all leaked like what you are descirbing.

Our last hope before tearing it out and going through it was a rope seal. Thankfully that fixed it.

Good luck.

On your motor? A rope seal?
I get no call

To the OP, If the rear seal has been replaced 4 times and still leaking then someone can't install a rear seal or the leak is elsewhere and that would be the cam plug in my estimation.

Take it to Bob George and have him help you out

Had the same promblem with my small block. The factory cranks had grooves cut in them to channel the oil away from the seal.The after market cranks do not have these. I bought a anti leak rear main bearing from mopar proformance and that fixed the promblem. Mp does not make the bearings any more but when i was at ich last winter they still had some for big blocks. i put 3 seals in and pulled the motor back out and took back to the machine to check it and stilled leaked before i found this out. Built a different motor and sme thing happened but this time i had to cut my own grooves in the rear main bearing because are wonderful dodge dealers said ma mopar quit making them.
I took the trans out removed clutch and put just bellhousing back on so i could start the car and be able to see back of motor.

Got a girdle? When I assembled mine the rear two main bolts were touching the back of the pan just a bit causing the leak. I even pulled the motor only to find it was the pan leaking. A couple little dings with a ball peen hammer took care of it. Is your billet seal retainer sticking above the block? that will allow oil to seep out at the pan also.

What brand of crank?

Your problem might be the finish on the crank. Im thinking your crank might have a very defined knurl. Ive heard that if you emery cloth the knurl off that it helps with main seal leaks. Of course the best way would be to machine it off, but if its the car, Ive heard that emery cloth works pretty decent. Ive heard that the knurl finish will seal better with a rope seal??
Posted By: Quicksilver440

Re: MAS. OIL LEAK, LAST TIME IM ASKING PLEASE HELP!!! - 02/22/11 05:54 PM

In my humble opinion...if you have a knurl...you need to run a rope seal. I've never had a problem with a rope seal on a knurled surface.

Re: MAS. OIL LEAK, LAST TIME IM ASKING PLEASE HELP!!! - 02/22/11 07:06 PM

Just a thought, you running main studs
Also some billet retainers collect oil and do not drain back to the pan. This will overload the seals capabilities.

The problem is not the people installing the seal! Its somthing else. the motor did not leak in 440 form it started after the stroker was installed and it had a rubber seal in it befor. the crank is a mopar crank . I have not tried a rope seal yet,that is on the list . The way it leaks i find it hard to belive its the cam plug but hey at this point Ill belive any thing. THANKS. NICK

Are you using silicone on the seal?
What type of retainer side seals?
Is it a black Polyacrylate seal or a orange/brown Fluoroelastomer seal?
What type of lube are you using?
Are you sure the groove in the seal retainer cap is lined up with the groove in the block when it's torqued?
Stock seal retainer or aftermarket and if so who's?
Has the seal surface diameter been checked or compared to a stock crank?

4 seals in a row with a leak, something is not right. No reason a rubber seal can not work.

Re: MAS. OIL LEAK, LAST TIME IM ASKING PLEASE HELP!!! - 02/23/11 02:22 AM

Back of the crank (torque converter hub area) drilled to far into an oil galley on the rear journal? Its rare, but I have heard of it happening over the years---and it is a new stroker crank......

Re: MAS. OIL LEAK, LAST TIME IM ASKING PLEASE HELP!!! - 02/23/11 02:22 AM

Black ,seal orange hi temp, rubber side seals,with silocone, without ,old retainer , new billet one 440 source the way it came, they told me to mill it.010. I have never seen any thing like it! This is the kind of stuff that happens to me , I once had a tranny built and it would not work properly found out it was a 727 built for a european car?

I simply mill clearance on the seal retainer to clear the studs/nuts. Same idea, to avoid the retainer hanging up on the studs/nuts.

You don't have to mill all the way to 0.19", but this one allows the socket in there.

Re: MAS. OIL LEAK, LAST TIME IM ASKING PLEASE HELP!!! - 02/24/11 12:36 AM

Pull it out, pull it apart and look at everything if you truly want it fixed

Pull the crank and bolt the seal retainer on the block without a seal, inspect and measure.

Inspect your crank and it's dimensions & runout.
(could have been dropped and has a bent rear flange )

I would assume you will still have problems with a rope seal.

I recently replaced a rope seal on a knurled factory crank with a rubber seal, no issues and dry as a bone FWIW.

Hi

I’m having the exact same problem, leaking oil between engine and Trans, check for leak on the valve covers, oil pressure sender, the plug next to sender, I have change the rear main seal once without any result, change the stock rear main retainer to a billet from mancini, still leak. Now I will pull out the transmission to put on a safety shield, then I’ll check the oil plugs and cam plug on the rear of the engine, think I must remove the flex plate too, hope it leaks there.

I hope you update us if you find the problem, I’ll do it here in your thread if it is ok?

Did you or your machinest mike the crank surface where the seal rides? You may have some wear there. Belive it or not the rope seal and the rubber seal will cause enough wear on the cranks surface to cause a leak.

Re: MAS. OIL LEAK, LAST TIME IM ASKING PLEASE HELP!!! - 02/26/11 12:40 AM

I think after the 4 seals not working you're making a good move by pulling it out and taking it appart.

Measure & check everything back there

We've all been there and usualy learn something along the way

I hope you find it, the cam plugs I had troubles with did not leak on the engine stand, even when priming and rotating it over several revolutions BTW, if you have not clean the front of the flexplate yet look at it real careful, if the main seal is leakning it has to come out on the flexplate and be slung out from there If the front of the flex plate is dry it is not the main seal, it is something else Good luck, I really hope you find it soon and that it is a easy fix

I know you've had this apart and tonight I didn't go back through all the previous post but is the rear seal facing the correct way? And about the mechanic checking, might want to do that again while standing right there.

Re: MAS. OIL LEAK, LAST TIME IM ASKING PLEASE HELP!!! - 03/04/11 02:56 PM

One little detail often overlooked: The seal area on the crank could have a runout. I have seen ground cranks that were not properly centered and when ground it looks perfect, but the seal area which is not machined now will have a runout. It is easy to check with a dial indicator on the crankseal surface and turn the crank, you will see if it is good or bad. I do not know the tolerance, but when I grind cranks I try to get the runout here (as well as upfront) to be closest to zero, and always less than .001"
Just my
Thanks, please keep us informed....

I will be the first to admit that over the years my addiction to buying used small and big block Mopar engines (340's, 360's, 440's)has grown. I usually strip them down and scrap the parts I won't be using and store the rest for future projects. I can't tell you how many times I have taken these engines apart and the rear seal has been installed backwards. I think someone should take a good picture of one installed properly and place it in the archives.

Call John at Hawk racing, 951-369-0200 and ask them about current prices, if in stock or not and shipping costs on one to you I have used several of there Chinese imports in motor, no problems so far, including beating the snot out of the motors Like all things, have it check by someone you trust as soon as you get it to make sure it is useable

Yes, I still have the rest of the engin but a look at the pistons and it looks as if the rings were not properly spaced ... so what else is wrong???

What was cracked on the crank to cause the oil leak? Was it about to break in half?

Re: [b]MAS. OIL LEAK, LAST TIME IM ASKING PLEASE HELP - 03/22/11 03:38 AM

I dont think it was ready to snap in half but the guy said they maged it and it showed several cracks in different parts of the crank, I have not seen it yet. Either way its not good.

not sure but did you get a chance to drive the car? was there any vibration? i just tore into a fresh hemi today to fix an oil leak that i think is coming from the rear main seal, got a mancini billet kit, but i have been chasing a vibration in this car for a while at about 60mph when i let off, does not do it if you hold the car in second, yes new driveshaft balanced twice, checked everything else over and over, hopefully its not a cracked crank.

Yes I drove it to work and to get gas ,didnt seem to have a bad vibration. With magnafluxing , from what I understand there is liquid and powder mine was liquid and checked with a black light . The guy called and said it hadseveral cracks so I will take his word thats what he does. I just ordered a new crank ,bearings gaskets ect..IM BROKE!!

i don't think a crack could cause a vibration, but just wanted to check with you on that, put mine back together today with the new mancini seal retainer and seal, see what happens,i did find the seal in the original retainer was not sitting flush on one end and also there was oil behind the side seals, hopefully that was the problem, now i need to get the caps on the master cylinder to quit leaking, i have the mopar plastic reservoir one .
