I have rebuilt my 1997 Ford Mustang Cobra SVT. I put in an aftermarket oil pump a Ford M-6600-046 STD is the oil pump. It seems to be leaking at the bottom of the oil Housing towards the engine. When I installed the oil pump, the shaft that hold the oil housing to the engine and the oil filter also screws onto this shaft, Is there a O-Ring in the middle??? I know there what looks to be a slot for an O-ring but the stock O-ring doesnt fit. Any help would be appreciated thanks.

 

i cant quite figure our where your saying but ive had a similar prob a couple times...there is the engine then oil cooler bracket then oil cooler then your oil filter....there is an oring between the cooler and the adapter and that goes out alot...gotta drain all the oil and your radiator to take it off clean out the canal and get a new o ring....hope that helps man

 

okay thanks, ill try that. the leak is so small it has to be an o-ring issue

 

ya the first time it happend to me it was nearly impossible to find cause it was so small and i just couldnt pin point it until it totally blew and you could watch it spray out haha...
