2001 V70 NA VERY bad oil leak - turbo block off blank bolt Topic is solved

Hello all, I have a 2001 V70 Non-turbo petrol car , and an oil leak.

It is a very big oil leak it can be seen dribbling off the back corner (between engine and bulkhead) nearest the front of the engine - (crank pully end)

It has coated the whole of the underside and BACK WINDOW with oil.

The odd thing is I have the timing cover off and it is very dry - bone dry - not a trace of oil.

I took the sump off but there was no sign of a leak from there, resealed it with expensive gloop and ir was still the same.

The whole of the engine is very dry eith just dry dust on it - except that back corner.

The oil cooler is not leaking and I have no turbo.

I suspect a camshaft seal or crank seal but would have expected some oil on the timing belt.

Any suggestions anyone? Thanks.

Check the other end of the cams... There's a seal at both ends... Mine popped out and it was a total disaster, cups of oil in minutes, till I pulled the crank angle sensor. Found the seal had popped and it was pouring oil.

Took me a week to find it. Since then... Not a drop!!

Good luck!!

plus 1, check cams seals. They can release a torrent of oil if one pops out.

Even though your car is non-turbo there is a machined hole for the turbocharger's oil return line.
This hole is capped and that cap can come off. I've seen pictures so it must be true.
There was a p/n for the cap in the post I read.
That's all I have. Kira

Sorry, only just seen your request for a photo. Unfortunaly I couldn't even see it because of the location, I don't think there is anything else near it and mine was easily turned with my fingers,

can you describe the location of the blanking bolt. under timing cover or on backside of block near top/right?

Sorry, only just seen this. The blanking plug is difficult to see. I took out my drive shaft when hunting for it.
If lunder the car looking at the back of the engine (the side nearest the back of the car) it is on the extreme right fairly high up on the block..
I found it by running the engine and watching the oil trickle off the R/H corner of the block and down the oil pan
