1996 Volvo 850 T5 - Severe Oil Leaks

Post by **jblackburn** » 15 Jan 2010, 22:57

Sounds plausible to me! A much, MUCH easier fix too. See if it's belching oil out the right side of the engine block - that's a good description of where to look.

And it's Justin btw

THAT'S HILARIOUS...it's 1:03 and you managed to crack me up...somehow I always read your username as :"Jackblackburn"....sorry for the confusion....I hope you don't plan to sue me for slander....because if this 850 keeps leaking oil I might run out of money to buy more oil ...

...I don't show up to court to defend myself

Haha...it seems like the oil leaks originate from the places I circled ...but I will look into it once again...the turbo drain line is that the same as the turbo return line?

by the way I'm Adam!

No worries, it's all good!

I think if my name were Jack Blackburn I'd have to change it. I hate Jack Black more than any other actor imaginable

Yes, the oil return line is the same thing. They are known to leak quite often.

haha ...yeah he's definitely not the best actor...

...I am thinking is there any way I can check to be 100 % certain that I don't have a PCV problem without actually taking everything out and inspecting?...because like I said I have no moke coming from the dipstick at all!----And pressure was tested by Volvo and they said it was great (I'm pretty sure the PCV was done in the last few years by a stealer when the PO had it)

My platinum wagon's dipstick location spews all sorts of smoke ...but not my sedan...I'm just leaking oil...

Welcome to the forum, I wish you enjoy being here.

Oil leak from the turbo return line is a common problem and is a cheap & easy fix. You only need to replace the seal ring & gasket. The following vendorhas all you need:

Seal ring:30637866
Gasket: 3514546

If you have floor jack + jackstands + common sense for safety, you can do these by yourself, otherwise you may want to take it to a shop.

Good luck to you,

JPN

I think this may be my exact oil leak problem.... and the solution for it...I don't have to replace the return line do I?

+1 on the turbo oil return. but you really need to get it clean first, it's NASTY under there!
my take on the pcv is if there's vaccum at the dipstick, it's working. No need to mess with it if it works. That is....unless everthing else on the car is dialed and you just want to work on it.

Some thoughts reading this topic:

More and more one of the biggest "takeaways" I have from reading what you guys write here at MVS about our 850, S70, V70, XC70 and C70 cars is take care of your PCV system before it takes care of your savings account. Pressure caused by a neglected PCV blows out rear main seals, and as Justin said, that's a very big problem. Big enough, I'd say, to land a good percentage of our 850, S70, V70, XC70 and C70 cars in the junkyard due to what I'm calling Volvo Rot. I did my PCV system at the 11 year / 90k mile mark and am glad I did, looking back.
When jacking up your car on jackstands or ramps, please be careful. A family friend and father of two young girls died about 15 years ago because he was crushed beneath his car while working on it. Sorry for the visual you undoubtedly got from that. I mention this about once a year in this forum, not to be morbid, but on the hope it will save a life or limb.
Tracing an elusive oil leak requires cleaning oil and grime off the engine and components just as good athletic performance requires stretching before taking the field. The former "jus ain't gunna happnen" without the latter. I had the famous turbo oil return line in 2000 or 2001 and was able to narrow it down by simply going under the car once a day with a rag and wiping down the underside.

Someone has been reading my post..

...The safety heads-up is very much appreciated...I have been trying to be safer myself as well(using 2-3 jackstands instead of just 1, placing the tires under the car, blocking the wheels, double checking everything before going down under,and taking my sweet time!!!)

They say haste makes waste...and nothing is worse than the wasting of a life due to an ignorant mistake.

I also usually enlist the help of my young brother.....BIGGEST HELP OF ALL!!!

He might notice something I didn't and if anything does happen he'll be able to call for help too, RIGHTAWAY!!!

!!!!!BE SAFE!!!!!

haha you even changed my title

...I'll keep it more to the point next time!

And eventually! Will look like this. I have oil dripping as far back as where the cat. converter ends.

As far as the "Volvo Rot", I could see someone ignoring this and not looking for telltale signs, running the engine out of oil completely, and destroying the whole engine beyond point of repair. Mine's becoming quite a maintenance hog lately, but it's just too good of a car to just get rid of. They just aren't the kind of cars that you can get by with owning without occasionally checking up on things by yourself.

I've had a car fall off jack stands before while tugging on a wheel lug, and it scared the heck out of me. I prefer ramps unless jack stands are absolutely necessary.

Mine looks more or less like yours up underneath the hood, but here's some of the underbody.

I'll add some pictures of ours.

Good luck, hope this helps.

I appreciate the photos, they're very good, I was wondering how many cam shaft seals did you replace?...2...The rear 2 or the front 2?...Thanks in advance!

Turbo 850,

We replaced the one behind the cam shaft sensor and the one behind the distributor. Both were on the same side, where the oil leaks originated.

Hole that helps.
