Just picked up a 99 v70 glt turbo. Was just given the car a couple days ago since the old owner went and bought a New 2005 v70 that was maintained by the dealer in and out.

The 99 v70 is now in my possession at my place and from what I was told, coolant was not lasting past a day. Once coolant was topped off at the reservoir, by the end of the day, zero coolant in the expansion tank, all leaking from behind the motor and to make matters worse, the v70 was drove while low on coolant and somehow blew oil everywhere (which looks like it came out of the pcv under the plastic valve cover) and now, wont start. I have researched this issue and I'm trying to determine if either A): I have a hose leaking coolant out or B): A blown head gasket.

Thought about a compression test first thing when I'm able to and figured I could get a head start with knowledge on this issue before I get started and put as many of my not so many hours I have into this first go and what steps should be taken.

Thank you. Hope to hear something soon!

There is a rubber coolant house by the turbo that commonly leaks. Not really sure what it is called exactly, sorry

 

Compression test would be a good starting point.
The PCV breather tube from the top of the head may have split/burst or come loose, hence the oil all over the top.
Coolant loss whilst maybe down to a blown head gasket could also, if your lucky be simply a split in the coolant reservoir or the cap needs replacing with a new one to seal correctly.
Dont keep running her if she is going up into the red or things will get worse.
A 'glove test' with the motor running (but not overheating) may indicate the health of the PCV system provided the top breather has not split or come loose.

 

I'll be doing the compression test later today after work. & yes, the breather tube was cracked at the very end where it meets the motor. I know over time the original plastic tubes become brittle and break.

A glove test will be a negative. Doesn't run and that's why a compression test needs to be done to determine if It's blown or what!

Tanks for the input!

 

Now I have completed the compression test as much as I can recently which didn't get me very far since the v70 isn't running at the time. So no REAL/accurate compression numbers are able to be read. I wont be able to dive in to look at the hose to see if the leak is coming from there. Though when I did check spark plugs, some were drenched in coolant and some with oil. Would that help with diagnosing if it were something simple or way worse, such as a blown head?

 

If there's coolant on the plug, the head has to be pulled. Could be just the gasket. Could be a warped or cracked head and/or block.
