88 740 turbo going throw a lot of oil
Oh, I'm going throw about a qt every 250-500 miles.
It's got 160K and the engine pistons are a bit noisy. because of this is it burn oil? I've heard other 740 and 940 this loud that didn't seem to go through as much oil as I do.
I've had the car since 145k. and I've been dealing with oil consumption. I've replaced the oil and crank seals, the dizzy o-ring, oil pan gasket, oil fill cap o-ring. I've looked over the car don't see any major leaks that would warrant the oil I'm going through. There a little at the drain plug, valve cover despite putting on 2 different new oil fill o-rings it's sweating from that area....
Today I was looking at the car and there oil at the idle adjust screw, I pulled the intake tube and theres a bit of oil in the intake tubes. not puddles like I've seen in VW's. I even pulled the tube from the turbo to the intercooler inlet and I don't see a ton of oil in the turbo, like maybe a seal is bad.
Long story short I'm curious if a gummed up oil trap could cause issues. o lets say the ports/path for the fresh oil that gets pulled up with vapor isn't able to go back to the crank case and is being sucked into the intake manifold and intake tubes???
Also I was messing with the flame trap and when I removed the vacuum hose from the flametrap to the intake manifold a bunch of oil started squirting out the oil dip stick tube? Is that a sign a a clogged oil trap?

I know of that heated element of some sort on newer 5 cylinders. That's not on mine.
I'm sick of putting money in this turd. to add I've never see any blue smoke ever. What I'm really curious about is if it's normal for oil to splash out the dipstick with the vacuum port removed? I've seen them so bad that oil comes out with everything hook up.

no oil should be splashing out of the dip stick under any conditions, that suggests the vent tubes are completely plugged up. if thats the case, your engine will blow its oil seals eventually, and oil will start coming out the drive shaft, or camshaft or anywhere else it can.
if you remove the oil filler cap with the engine idling and lightly place it back over the opening, does it chatter, or does it get sucked down? it should get sucked down slightly, it definitely should NOT get blown up.

Is it possible because of the maze inside of the oil trap that the system needs engine vacuum to help pull the vapors into the manifold?
Though if it's doing it at idle with the least amount of combustion, firing events, and greatest vacuum, going down the road it presumably has to be getting worse. More money to spend..... IPD still the cheapest place to get parts?
I see the heater.

IPD and FCPEuro are good for aftermarket and common tuneup parts. for more unusual real volvo parts, you pretty much have to go to a dealer, or Volvo Parts - Authentic OEM Volvo Parts direct from Volvo Parts Webstore | VolvoPartsWebstore.com or TascaParts.com (both dealers with webstores)

replaced the oil trap, maybe 30 minutes total.
there wasn't as much build up as I thought there would be inside the box. I need new batteries for my digital camera so I haven't snapped a picture.
I can say that now when you remove the vacuum hose at the manifold oil doesn't squirt out like before. Just smoke. Plus the hose from the oil trap to the flame trap was cracked bad, so I also fixed a vacuum leak.
PS said crack hose from IPD is way beefer then the one I had on there and sure will last way longer.
