Engine: B5244: - Head gasket oil leak

polainm · May 13th, 2022, 15:01

Hi. Been in/out VOC for a few years, using parents' Volvos in the past. Recently bought a 2005 V70 140 petrol, and could see oil leak from front of engine. I thought 'OK, probably cam seal/crank seal, might be oil filler cap seal too, maybe PCV bits or sump gasket - how bad could it be?' So I bought it. Now in bits at trusted indy and they found only dry seals (I'd also done the glove test for PCV pressure - all OK).

They have traced it to the front left corner of the block (left of cam, head to block gasket) and oil is leaking from here! I have never heard of this happening to this block. A specialist engine rebuilders I will be using has said that they have come across this problem on a couple of B5XXX blocks but it is rare.

We all believe the water pump *might* have failed, and the block overheated. The water pump is recent, along with cam kit. So the gasket might have failed as this time and the previous owner has just run it as Amoco Cadiz, jet washing it prior to MoT

So now muggings has to sling 'value' of V70 cost at labour to get head skimmed etc. I can do suspension rebuilds DIY/reflowing solder/SAS replacement but head removal of this engine is beyond my skills.

My question is (got here eventually) is how many of you out there have had this failure, and what did you do? Scrap/open wallet surgery/sold it to another mug...?

Yours, in pain, Matt.
