Ive checked all those initially, all in all ok ...

T.W: Does your engine have the plug wire loom brkts at the rear of the block? It was posted here some time back, that if they aren't there, (mine aren't) one of the bolts goes into the valley & if missing, it will leak.

Thanks guys, I knew what you ment Ted, my answer was when fitting the seals it must be obvious that they stick out too far. But I dont know how much bigger 312 seals are?

 I have looked in the past for ECZ on the caps and saw nothing.  Im damn sure I had it all spotless when doing it. I use contact cleaner to blast away oil and small bits as well as blowing it with compressed air. I'll be honest and say the only thing I did do that was different Ted was I sat the seals flush with the block and cap. I know that they sat just slightly proud [as it should, a bees dick as we would say.. ok maybe a little more]. I did think about this, I would have much prefered to do it your way BUT I had no way of gaurenteeing that the ends sticking out would slide into where they should when putting the cap on. On and engine stand guess its easier to check that stuff. Im still confident I did everthing correctly it should have worked...

 I know where the oil is coming from Its still the same.. It comes from between the motor and trans and starts halfway up [possibly a little higher] and its there on both sides

Because its the same as it was Im thinking it now must be something else..

I think your next step should be what Pete suggested in his post. here's one available a NAPA. https://napaonline.com/Catalog/CatalogItemDetail.aspx?A=NTE784733_0282517238&An=0 Not cheap but may save you Heartburn and time...

Ditto on what Bill said.  I was referring to using the 292 seal on a 312 crankshaft.  Just insure that your main caps have EBU on them and not ECZ.

Ted is referring that using a smaller 272 seal on the larger 312 crank then there would be a problem. I believe you have 272/292 and that felpro seal is correct, ted will correct me on anything ive missed or out on.  My personal thoughts are that replacing a rope seal while in the car with neoprene seal is more likely to have problems, as removing all traces of old seal from block groove would be near impossible and i allways check if seal half in block sits flush with block as i,ve come across some early blocks with shallow depth groove that distorts seal when cap is snugged down hence going oval and oil leaks follow. Just my view on general points. I have renewed neoprene seals previously  fitted in block and is easy.

292 ,Ted I see no evidence of it being a 312 [not sure if that would be likely in a town sedan?]

The seals seemed to fit well. They came out of a Felpro kit FS7999 PT -3.

On the seal packet is P6141-1 there is nothing marked on the packet that held the side plugs..?

Surely it would be obvious if they were 312 seals, or is there very little in it??

Are you dealing with a 292 or a 312?  There are two different neoprene seals involved here and if the wrong one is being used for the application, the rear main seal will leak.

Well after fitting the new rear main seal seems its a failure ; o (   

sure I did nothing wrong... Bugger!!! 

Doh!! could it really be the cam plug .....
