Rebuilt an engine joined the gearbox and filled it but it's dripping every thing on it is tight check about 4times. Where it joins the engine right on the bottom..

What's leaking, engine or gearbox?

Back of engine could be the rear crankshaft oil seal, or more likely the sump gasket is not correctly seated.

Where the gearbox joins the engine (the bell housing)?

Could be the sump or Crank sill.

I trust you never filled the bell housing. lol

woolford

It's yellow so it gearbox. There is a drain hole or something at bottom of bell housing it's coming through there. Can't get head round it as everything it tight and all new seals

thats all fine as long as the new seals are seated correctly

ST Turbo

Sounds like brake fluid from your clutch release bearing to me!

woolford

The pipe isn't connected to the box yet just filled box and engine

theheap

Is it new box (new to you) maybe the sill on the shaft is kaput or the box has a crack in it somewhere?

woolford

No it's my old box was fine. So annoying

are you saying the sump hasn't got a gasket? it should have !

woolford

It was sealed with a silicone stuff.. No gasket they don't have one

phil_focus

i had to replace the sump on my focus last week and allpartsautomotive supplied me with elring dirko. its made in germany and has sealed my sump perfectly. both surfaces need to be clean dry and degreased first.

mitters

the silicone you want is( RTV silicone sealant ) loads of makes around i paid about 5 pound for mine cos i thought the sump was leaking ,but it was the alloy housing that its bolted to ,cos the sump is in two bits ,look close cos the oil gets blown to where you think the leak is ,mine only started leaking when i took my engine out and put it back in the joint must get disturbed if you sit the engine on the floor when its out ,

I always use Loctite Blacktite for sealing Zetec sumps.

woolford

Were will I find that will??

Thanks
