Either trap will bolt up just fine to your engine, and will even work as long as you keep in mind that each uses a different small hose. If you buy a kit, the hose should be matched up to the trap properly and you will be fine.

I discussed this a bit at the end of this thread https://www.matthewsvolvosite.com/forums ... p?p=351093.

Oil trap 9146756 must be used with elbow hose 1271771, note it is straight

Oil trap 1271650 uses a different elbow hose, 1271653, note it is angled

Thank you very much for the photo, and a concrete answer. Rather annoyingly, EVERY picture I could find of the two different traps had them in orientations such that there was no equivalent combination, so I couldn't compare mounting holes very well. It definitely was clear from the pictures that the lone port on the side of the box (don't remember where it leads to off hand) was spaced differently in relation to the nearby mounting hole on the two models. The variation in hoses shows how that is handled. I hope other NA owners happen to stumble upon this in the future, because I couldn't find that information anywhere. Similarly, the dealers didn't seem to know this either.

I admire college student who can handle a Volvo 850 PCV project!

BTW, have some generic 5/8-inch hose on standby, they are about $1/foot at local parts store. About 6 foot length is plenty.
Save the long vent hose from the kit you ordered and sell it later.

I am writing this for future readers, as much as I am an FCP customer, for this kit @ $180, it is way over-priced! As I mentioned previously, if one orders ONLY the necessary items from local Volvo dealer, the cost should be around $60-$70 and that is it. FCP pricing is higher than Volvo dealer!

I am attaching the photo of the kit you ordered and mark out what should be re-used (oil trap), what you be substituted (the long vent hose) with generic 5/8-inch hose.

I suggested FCP mainly because it is closer and shipping would get it to you sooner.

Have fun. I'm helping someone with a PCV job today.

You certainly are right, those parts are overpriced. From what I remember, even the dealer was less for the oil trap. I saw that my local autozone sells the 5/8 hose for that price. When substituting heater hose for 9125598, what size hose is used for the smaller vacuum line?
It likely was mentioned inside the thread regarding the substitution, but I read it while trying to rest with over a 102 fever, so my attention span was definitely not up to par. Lastly, my thought process with the oil trap was that if one currently on the car is at all damaged, or was damaged during removal, I'd have a major problem, so it was worth the money to make sure I have what I need.
I guess I did get pretty lucky in that my engine appears to have one of the simplest PCV systems across the 850 line, since there's the lack of the PTC and EGR valve.

Edit: Scratch the vacuum hose question - found that it's 5/16

Yes, some info about the smaller vac line is tucked away in the same follow-up post where I suggest re-using the oil trap: Use 5/16 vacuum line for the nipple on the intake manifold. This will be a little big for the nipple at the flame trap, so make sure you have a clamp to tighten it down well at that end. But don't break the fragile, plastic nipple! Generic rubber vacuum hose is great in this application, and cheap.

For the oil trap line, one of the things talked about in that long thread is that the vent has to make a 90˚ bend and there is some risk of cheap heater hose collapsing, a few people have posted about that problem. I would suggest using fuel line or a heavy heater hose. Or even just buy a heater hose that is pre-formed with a 90˚ angle in it, I did one that way last spring, the only catch was I had to use RTV silicone to seal the flame trap housing, I don't remember if that was because the housing was in bad shape already or because of the angle of the heater hose:

: Gates 28469 is a quality hose, cost me $14

: Size is close to what is needed

: Trim to fit

: Ready to install

: Hose installed on the oil trap

: Oil trap installed

: Other hoses at the trap are Volvo branded ones

: Connections at the flame trap housing (throw away the flame trap disc inside!)

: Final setup at flame trap housing

Sounds like a plan. The guy I helped has a insulated attached garage and a nice heater in there. I was very comfortable. Today I think it only got up to 27 degrees in Clarksville OH.

Took about 2 hours and 15 minutes. Likely my fastest time ever. Dropped a couple of bits, pulled the manifold a couple of times, etc.

The KIT from FCP had different parts than what came off:
1. The smaller box was sent.
2. The straight hose was sent (so the smaller box was fine).
3. The hose from the box to the top of the head was different. Went between 1 & 2 instead of 2 & 3. (No big deal I guess).
4. Extra parts not needed.

At any rate, all went well and smooth. The lower port was blocked and a few pieces were broken. Now it has vacuum on the head instead of pressure. So, all is well.

I got an email from FCP saying that the order was shipped on Wednesday (two days after I placed the order) via ground (I paid for 2 day). Instead of the parts arriving Thursday, they were supposed to arrive next week. To make a long story short, they're overnighting a second kit on Friday, and they credited my the shipping costs. I really appreciate that they so promptly came up with a solution, because the parts were to arrive so late that I wouldn't have been able to get the repair done.
Robert, did you use the 850T300 kit as well? Also, is it required to remove the injectors? I've looked at several tutorials, and it appeared that some did and some did not. The injector rail appears to go into the intake manifold, so can I disconnect the fuel rail and injector wires, then leave the rail on the manifold?

Yes, you can leave the fuel rail attached to the manifold after disconnecting the injector wire and fuel line.
