My dip stick at some point popped up and is blowing oil out of it at highway speeds.
What should I be looking for?
Rgrds,

You didn't say how old your car is, nor for how long you've owned it, but it's probably a neglected crankcase ventilation system. Volvos typically have a "flame trap", which is a screen that allows crankcase fumes to be drawn into the intake system (the screen prevents a backfire flame front from flowing into your crankcase to ignite fumes) -- resulting in a negative pressure (slight vacuum) to exist in the crankcase. Sometimes this screen (or one of the hoses with it) becomes clogged and pressure builds up in the crankcase, and so this should be part of regular maintenance.
In other words, you car needs some until now delayed, but badly needed, otherwise routine maintenance.
But there is another possibility: at times when there is a blown head gasket (or bad rings, etc.), pressures can build up to a point when the dipstick, or seals, might blow. I hope this isn't your case.
Good luck.

Oooooops
Just purchased. The only records with the car were from the CarFax Report and it appeared that for most of it's life the owner took it to the dealer for service. I called the dealer to get a printout of the complete history and they tell me that even if they remove the previous owners name they can not "legally" give me the report?? Even though the dealer who sold me the car gave me the title, providing me the name and address of owner.......

I just remembered, slap on side of head! When I bought my V70, I emailed the PO and asked where he had it serviced. He called his indie and told him to let me have a look at the service records. When I phoned the indie, I wrote down all of the major stuff w/date,miles.
I used phone book and yahoo to get email address.

What a bunch of crap. Drive over to the dealer and ask to see their history on the car. They have it and it is not illegal to let you see it. They may not want to print it out, but should let you write down dates, miles, and reason for service. This is not proprietory info.
Now, feel lucky that the dipstick popped out and not the rear main seal! Your car does not have a flame trap, but the hoses from the oil separator (under the intake manifold) to the turbo intake are probably clogged and need attention. Also check the hoses on the vacuum tree and make sure they are open. You might have to remove the intake manifold to R&R the oil separator, about 5 hours DIY.

Well followed the procedure you sent me Klaus and all went well.... That the good news... the Oil seperator and some of the hoses seemed like they were changed not very long ago...and was concerned as I thought the breather is why I was bowing oil out the dip stick... But i did find one of the nipples on the tree on the bottom of the intake completly plugged, which then made me feel better knowing (or at least thinking) I found the problem....
Drove the car all week locally with no problems.... then I drove on the highway for ~ 100 mies at 80-85 mph and the entire topside of the motor is up to the firewall is covered in oil. The dipstick didn't appeared to be popped. so now I have no idea where the oil is comming from??
Any help would be appreaciated. My daughter bought this car and I've been trying to get it to her for over three weeks....
Thanks

RT,
When the tree has a clogged hole, I like to take the tree off and verify the entire tree is clean. Also check the small hose and make sure it is clean from one end to the other.
Running at 80mph should create a lot of vacuum, you might want to check the compression??? Bad rings are not common but a rare possibility.
Or, you could just have an old seal on the oil filler cap. They get hard with age and need to be replaced, just $1.00 at the stealer.

Thanks Klaus;
1- Could that much oil come out the oil cap even if the gasket was bad/old?
2- Good idea t do a compression test anyway, but wouldn't bad rings burn oil? How would the oil get all over the engine compartment?
3- What should the compression be?

I was just guesing the compression stroke would raise the crankcase pressure. Probably wrong. Pressure should be around 150psi on all 5 cyl, +-10%
There is enough air moving through the engine compartment at speed to blow the oil dropplets everywhere. Also take the cover off the timing belt and check the seals on the cam shafts.
Be careful washing the oil off the top of the block. Water will drain down to the sparkplug holes and you will have to remove the water with a cloth in each plug hole - been there, done that!
Nice puzzle,
Klaus

I still should do the compression test, maybe not rings, but what about Head Gasket?

BTW, I had the dealer who sold me the car change the Oil Seperator. I was a little nervous when I seen him probing and prying with exremly large needle nose pliers and extremly large dental picks to pry back all the hoses....
What if he poked a hole in one of the hoses? Would their be one in particular that would blow out oil at the 85-90mph range?

Whenever an engine is running, there is vacuum pressure. Lots of vacuum after the throttle is lifted and nominal when throttle is applied. Without vacuum, your car would not run. Enough said.
The oil breather system uses vacuum to get the oil fumes out of the crankcase and routed to the intake for burning, rather than just letting the fumes escape into the atmosphere. So the oil would not come "out" of those lines.
When the dealer replaced the oil separator box, did you get billed for various hoses or were the old ones reused? Specifically the one hose from the oil filler cap to the separator box.
You might want to remove the cover over the spark plugs and check that the hose did not come off and is snug.
When you said that there is oil everywhere, does it concentrate more in one area than another? Like the front of the engine, pass side, drivers side, etc? Could it be a leaky line at the radiator?

All of the hoses looked like they were very recently changed... Even the seperator looked almost new...
It definitly looks like motor oil, was also down a quart after a couple of hundred miles...
The oil is up and around the dip stick, though dip stick is not popped out, heavy oil basiclly between radiator and just under intake.. Does oil go to and from the radiator? Does the Turbo's have an oil coiler?

All turbo cars have an oil cooler. The oil lines go from the front of the engine, at the bottom, to the passenger side of the radiator.
You are going to hate me. Part of the procedure to get to the oil separator box is to unbolt the oil dipstick line from the intake manifold. So try to wiggle the top of the oil dip stick line and make sure it is snug.
Then with a small flashlight, look down the line and to the left, where the oil separator box is. See if there is a puddle of oil under the box area, passenger side of the block. If there is, take the car back to the Stealer and have him fix it.
Last, but not least, take out the dipstick and check the 2 O rings. They must not be broken and in place.

Im glad you mention the dip stick:
The mechanic at the dealer put some die in a couple of days ago... We wiped her all down... I've been getting on her... Really cranking the turbo in... And no oil...
Two things;
1- I think the dip stick may not have been sitted all the way when I got all the oil all over the place last Friday
2- The mechanic was hitting the World Pac Forum and someone mentioned a retrofit for a "double 0-ring dip stick and modified tube... My stick has only one o-ring....
any thoughts?
Thanks again

So long as the O ring has no cracks it should be OK. If you do not feel any resistance, just a little bit, when you seat the dip stick, you may:
Get a new O ring.
Get a new dip stick and tube plus new O ring at the bottom. This requires an oil change, as the oil will run out at the bottom of the tube.
If there is no oil loss at sustained high rpm, then it probably was due to the dip stick not being seatted. Turbo boost will not increase oil pressure, but higher rpms will boost the pressure to above 50psi. So driving in 2nd for a sustained 5 minutes at about 55mph will be a good indicator for leaks under pressure. Besides, its fun :)

I convienced it was the dipp stick.... It is a very sloppy fit... With the stick seated just right of got on it, say +5K rpm's and no oil...
Who stocks the retrofit stick and tube?

I didn't know about after market dipsticks and holders. You might want to look around on Volvospeed. But getting a new one from FCP or Stealer might be OK?

I'm not sure if it was aftermarket or a Volvo TB that came out??

Where can I find a procedure for changing the Oil Seperator?
