Engine Oil leak

Posted

'01 2500

Buddy bought the truck from our company. He thought it had a leaky pan gasket. It threw down a good puddle last night in the shop. 

It's coming from the vicinity of the oil line on the vacuum pump where it goes into the block. I replaced the seal in the pump 2 years ago and it doesn't seem to be leaking from there. 

 

I didn't have time to put a wrench on it so I'm hoping it's just a loose fitting- but it doesn't look it's coming from the fitting or the hose. You can see a nice clean strip down the block underneath it. 

 

Anyone else run into a leak in this area?

 

He just had the head gasket done but it was leaking before that, not this bad though. 

 

Thanks,

Rob

Try to get a light and see behind the injection pump. It could be the tappet cover gasket back there.

Not a cover leak. Oil line was tight.

Told him to wash everything with brake cleaner, fire it up to make it leek  and shut it off. Then start taking stuff off until he can see it. He wasn't into it,  Monday ya know...

Tappet cover most likely. I just bought a new gasket for my truck and will be doing it very soon. It will leak fairly well from the tappet cover. Like mine is ar the rear of the engine. Also double check the gear case like mine is weeping between the block and the gear case so you'll have to remove the cover and tighten the bolts. If that doesn't work then you have pull the gear case which requires pulling the cam out. My last leak is on the wrong side which is my turbo return hose is weeping.

Hey thanks. Maybe I have the terms wrong. Is the tappet cover not the  valve cover?

Hmm. That looks like fun,

 

What all do you have to take off to get to it?

 

stuff

  

 

I dont remember, but it really isn't bad.  I think VP44, ecm, and lift pump bracket.
