We have fitted a rebuilt tuned and pre converted Zetec 2.0 to our Mk2 Escort, but the front crank oil seal was leaking pretty bad on first start up. I bought a Elring seal, and changed it. The old seal was damaged and folded back on itself, so I really thought it was fixed. But now the engine is back in, it is still weeping oil. I checked the crank wasn’t scored and was pretty careful to tap it in straight, so it’s really frustrating.
The engine is coming back out next week, and I will take off the sump and inspect the pump and crank. I spotted one American blog that said there is a special tool to position the oil pump to centralise the seal, has anyone got any tips I can look into or try out to fix it. The sump is the cast retro Ford one, and I’m pretty sure that isn’t leaking, but will check.
cheers.
PS is a uprated oil pump, or billet geared pump worth fitting while it is out?
