2002 V70 2.4T massive oil leak

Post by **ljsommar** » 16 Nov 2018, 09:17

My wife was returning from a girl's getaway weekend when she noticed the engine light flickering. Miraculously, she was right near at a gas station, where she determined she had no oil (big oil puddle under car). She called me, I told her to purchase 6 quarts of oil and see what happens. Well, the oil was leaking out extremely fast at idle, approximately a quart or more in 5 minutes or so. She had it towed to "Swedish Underground" an indie in Williamsport Pa, 3 hours away from home. The owner was actually there and working on a Sunday, he was so backed up. Well it's Thursday and he has not looked at it as yet.

The car has 213k miles on it and all maintenance is up to date. The PCV service was done early at (165k) due to me mis-diagnosing a bad vacuum line. I use syn 0W-40 oil and it was changed @210k. I had replaced the crankshaft seal (along with the oil pump O ring) at that oil change due to a small oil leak. It did seem to stop at least most of it. Before she left I added a bottle of Barr's seal leak additive because I thought maybe there was still some leaking.
I am not a big believer in additives but I thought it couldn't hurt.

I am not sure what can cause such a massive oil leak. Has anyone heard of the oil lines at the oil cooler failing?
It was very hard for my wife to determine where the leak was but she seemed to think it was the worst on the passenger side near the back of the engine.

Anyone have any ideas? Not that it really matters, I am at the mercy of a mechanic 3 hours away.
Thanks.

Oil lines for the cooler is possible as they are rubber. I think you will have to remove the engine tray and do some inspection.

My first thoughts were the PCV system, but I think its something else.

Would if I could, the car is at a shop 3 hours away. I am at his mercy and he knows it.

You're assuming he's dishonest.

No, not true, I have no reason to think that at all, but my options are very limited and I have never been in this spot before and I don't like it.

The biscuit style oil cooler on the 1999 on doesn’t have external oil lines...maybe it’s a turbo return oil line?

The oil filter cap is the other possible culprit, or the oil pump behind the crank pulley
