Just did this job last night and ran into a big issue when I was done. Went to crank the car and it would't turn over. I got out to inspect the engine to see what was up and there was fuel all over my block. I used this post as a reference but I did use the FCP video by Ben McNalley as my main source. Which means I removed the fuel rail and the injectors. I put new gaskets on my fuel injectors when I put it back together.

Fuel smell indicates I messed something up on the fuel injector reinstall, right? Any help would be greatly appreciated.

there is also an o-ring at the fuel line connection to the fuel rail, inside the fuel rail. make sure you didn't lost it, and seat it properly inside. you can use a very small amount of vaseline around the o-rings to fit them easily.

Ok, so I need the 1997 Volvo 850 PCV Valve Oil Trap, what hoses do I need. I want to replace the hoses that attach to this trap. I won't be doing it, I am just buying the parts. I found the Oil Trap but are there particular part names for the hoses? Thanks.

Look at www.fcpeuro.com or www.ipdusa.com Each of these have PCV kits with part break up and numbers.

ok I never responded to this, but my issue turned out to be that I installed that hose that runs the length of the manifold on the wrong side of that little bracket that is on the driver side of the car. Took everything apart, put the hose on the right side of the bracket, and the car fired up perfectly!

Thanks for all the responses!

SpeedyPete wrote:Hello all: Here are a couple of things to consider when doing the PCV Repair. .. Also if a rear exhaust cam seal leak is concurrent with this repair as was my last one, USE ONLY VOLVO BRAND SEALS. I bought 4 different seals for this and when you mic them you will find very slight differences. Stay with Volvo Brand seals only. They are worth the extra money. I hope this helps and best regards, SpeedyPete 8)
SpeedyPete - I ordered the exhaust cam seal from IPD and they told me that Volvo uses seals made by Corteco. Can anyone verify this? I did purchase one from IPD to replace the temporary "National - Federal Mogul" one that I got as a temporary solution from the local parts store.

It might be so cheap because it doesn't include a major piece of the puzzle. There's a PCV based insulated tube that goes from the left of your intake manifold to the right side of the engine in the PTC valve in the intake area. The picture of the kit in your link doesn't include that hose.

It looks like for your car it's this part. http://www.eeuroparts.com/Parts/52176/PCV-Tube-9470330/
Perhaps your car's pipe will last longer.

For my car, a 1998 V70 T5, I actually used my own tubing (Fuel line and heater hose) instead of using PCV again. It's a bit trickier to get on and you'll need to figure out the routing, but it's way better that the PCV - that stuff just crumbles over time due to the heat.

Simple - remove the plastic disc in the hose to the throttle body as seen here.

It's been some time since I have been on this thread, and I'm sorry if what I am about to mention has already been said. I did this job on my '04 XC90 a few years ago, then later replaced the cam seals to cure the oil leak in the timing belt housing - which I assume was due to high crankcase pressure. Ever since then the car has demonstrated positive crankcase pressure (glove test), but still developing leaks at the rear main and the camshaft seals. Further research led me to dropping the oil sump. The smaller (lower) port for the oil trap was still filled with sludge. It's unfortunate that it took me this long to uncover the problem because of the newly developed RMS leak.

Bottom line is if your lower port is plugged, drop the oil pan and make sure there is no blockage.

Genuine parts from volvo parts warehouse .com:

Oil pan seal kit $22
Chemical gasket $34
Oil cooler seals $9

Solvent bath at local machine shop $35

A hundred bucks I wish I would have spent earlier.
