no flame trap?

Hello I'm new to the board. I have been lurking for a while and I have gotten most issues fixed by searching. Lots of great info. except this one.

My wife have a 2000 V70 non-turbo. I have some oil blowing out of the oil filler cap. I have read that a clogged flame trap can cause this excessive pressure. However I cannot find the flame trap. According to everything I have read including the repair manual I bought says it's in the intake elbow coming from the air box to the throttle body. Am I reading this wrong?

Where do I go next?

Yes, the flametrap is located in the intake elbow. You should unscrew the cover of the throttle body. I would then pull apart the air intake hose and move the air intake elbow lightly to detach the flametrap component by twisting it I believe clockwise. You can then pull the actual flametrap by using thin tweezers or the like and replace. It is a really cheap component.

Here is an image I found on internet where you can clearly see the flametrap which is the component held by the hand.

However I think your problem might have more to with an oil trap or PCV system in need of replacement. There´s good instruction in this site on how to proceed. Check the repair database.

Best regards, Antonio.

To expand on the picture, the flame trap is located below the bayonet mount that has the PCV lines. It takes about 1/8th of a turn to release it. Most of us just take the thing out and throw it way.

Pull the flame trap out and toss it. You don't need it. Check for crankcase presure with the dipstick test. After the engine warms up pull the dipstick with the engine running, if smoke is puffing out, it's likely due for a PVC replacement. I suggest getting a kit that has all the parts rather than trying to clean and replace the old ones, FCP has a good one. I will be doing my third one as soon as the weather breaks. Read over the tutorial several times. Make sure you have all the tools you need. Have some band-aids ready you will likely scrape some knuckles. And the new flame trap that comes with the kit? Throw that out too. This is an important repair to prevent bigger future problems. Don't ignore it.

Is it supposed to be located in the nipple that is shown in the left side of this picture?

ok so it looks like the housing and flame trap have been removed. All I have is a nipple. So I guess I'm looking at a full PCV job on the car. Are there any other item I check in the meantime until I can order the PCV kit. It looks like it's about $300.

I did the blocked PCV check and I did not have a dancing oil cap, or a smoking dipstick. It seems to leak the worst after a long trip. The reason for me looking at this is that i have multiple small oil drips after long trips. I am wonderinf if it may be as simple an old oil filler cap gasket. I have read that many people replacement pretty frequently. Mine seems to snug down good and tight, but it does look old and dry.

I have read here that a few people mention replacing just the gasket. I checked with IPD and the dealership and they both only offer a new cap.

Dealers SHOULD sell them.

I believe FCP sells just the gasket - but if you're going in for shipping, add it to some other things as well.

Take a second look at the PCV system for a 2000 V70 from Eeuroparts.com. It may/may not have the flame trap system removed from that year entirely - the systems were all changed slightly in the 1999 model year.
