best place to get a crank rear oil seal for a 4x4 saph cos. already tried a genuine one from ford & it still leaked once i got it on track

 

Burton Power?? I wouldnt have expected a Gen Ford item to leak unless it was installed incorrectly??

 

Matt Lewis.

 

but it does installed enough before & it was done with the engine out so not as if it was awkward to do lol

matt lewis supplies the genuine ones though doesn't he? thats whats already in there

 

That is a bitch, not like they are the easiest things to get to either. Is there a deep wear groove where the seal lies or do you have a lot of piston-blow by pressurising the crankcase??

 

nope checked the seal carier & it all looked good when i put it in.
running a spec r breather vented from both sides of the block with a proper oil return below the oil level so should be breathing ok. engine has done little mileage. only happens when on track ie sustained high rpm & hot oil

 

But was there a grove on the ground cranck face wher the lip of the seal runs??

Maybe a case of the oil getting so hot its going extremely thin and by-passing the seal.......Do you run an oil cooler?

 

no oil cooler as yet but according to my oil temp guage the temps I'm seeing are spot on ie around 100 degrees
crank was fine btw

 

how are you fitting the seal?

 

Hmm its a puzzler. I would def run an oil cooler if you are on the track and maybe try a different oil perhaps, there is no reason why it should leak if its fitted correctly and everything is as you say it is.....

 

bit of sealant smeared round the outside, pressed into the carrier off the car then fitted into place. normally use a small plastic spatula to coax the lip into the right place without dislodging the wire that runs round the back

 

I know, tried silkolene & mobil 1. this is the second genuine ford one thats done this

 

just looked on ebay at the one matt lewis is selling & it looks different to one that ford supplied me with

 

Give that one a try but the only other thing that i can see causing it is that the area that the seal runs on has been ground when/if it has been machined throughout its life or the main bearings(especially No. 4 & 5) are severley worn but if this were the case i think you would have known about it before now!

 

Am I going mad?

There is not an alloy carrier that the rear seal sits in? It sits in a combination of the block and the rear crank main cap? Are you sure your not talking about the front seal that sits in the alloy fron cover?

Either way, genuine ford items should be fine. Matt Lewis for supply of these.

 

Take your breather pipes off and clean them out, and the can if it looks like it needs it.

 

u r right I've gone mad - it is the rear oil seal that leaking but for some reason I'm thinking about when i last changed the front one

 

done m8
how's tricks?

 

slow
expensive
cold
noisy
any other negative words you can think of

but at least I haven't got a shitty oil leak

 

only cos the engine aint in the car

 

400 running in miles done

shove that in your pipe

 

what actually in your car????!!!!!!!!!!!!!!
give u a call over the weekend to catch up

 

I always use VITON seals wherever possible, these are vastly better than std ones, as they are meant in high heat loaded applications, and have much higher clamping pressure than std seals,(which should have been fine).
All the viton ones I use have always had a wire that was in such a depth of moulding that it can't even be got out when you try, so would never fall out, when installing.
On crank seals I always plastic them in when inserting, a thin ring that goes between crank and seal, then just rotate whilst pulling out gently, with everything oiled.
tabetha

 

where from please?

 

all the gen ford seals ive fitted come with a plastic fitting cone. i use only the gen ford seals

and have all been perfect, it wont be the seal at fault.

 

got a genuine one sat here mate, can be posted, you will recieve Sat, PM sent

 

I agree, there must be an underlying problem somewhere.....

 

the man talks sense ford seals are shite
