2012 Oil Leak Alternator/vacuum pump

#1 by James85 , Mon Feb 04, 2019 8:51 am

Good morning all,

Background, 12 plate LB done about 79000 and serviced well. Yesterday I see oil along the head gasket on drivers side of engine from front to back and i can see it has then got on top of the diff. I cleaned everything down and steam cleaned it myself.

Drove 150 miles and checked last night, the leak seems to be over the top and RHS side of the Alternator vacuum Pump at the front of the engine. I have uploaded a photo.

Anyone have or seen this before? Is it a common problem? Am I looking at just replacing parts hoping its not the head gasket and just chasing a problem around?

I have not had to top the oil up at all, there's no pooling of oil under truck, the oil looks ok and the coolant is good too, no overheating and seems to be running fine otherwise.

Any help will be greatly appreciated.

Looking at it, I can not tell if it looks bad or if the oil from the front has just seeped round it. There's no leaks from the top anywhere either.

Found it, its on the vacuum pump, so as you crank you can see the oil seep through the sandwich plate. The O seal inside must of gone. Any body done this job? I would attempt it as long as I havent got to dismatle the world before hand.

To be fair i think it might just be a case of new pump???

Easy enough job? I seen the two O rings, however the leak is between the sandwich plate and pump itself, so would those 2 O rings sort that or do I have an actual pump failure you reckon?

No its the one at the top of the engine. I wrongly thought it was at first.
