Cosworth rear crankshaft oil seals....whats the difference?

[M K]

Hi

I think i have a leak from my rear crankshaft oil seal on my engine but not confirmed yet, was new when built but then sat around for 2 and a half years before engine has been run since dyno

Anyway i have ordered 1 from piero @ xpower engine works seen here

But i have since seen these genuine ford items

Now the ford 1 looks quite different ? a lot deeper, possible twin lipped?

Anybody know about these and recommend whats best if i do need to change it

Thanks
Marc

the genuine ones have no spring in the back but non gen ones do and seem to work so much better
in my own expeirience anyway

X power ones are best

Cheers for the info guys

Got an Xpower 1 coming tomorrow so that's good lol

Piero would know which is best,hence the one you have.

gen ford ones are crap,the plastic bit in that pic is the fitting guide by the way

Well pulled the gearbox and it's not the crank seal leaking anyway it was oil that had ran back from my badly leaking half moon seals that are now fixed
