P80 PCV System Repair on a Volvo 5-cylinder (-1998)

[iceracer]

Thanks gents. I yanked out one of the spark plugs just for curiousity. It is tan colour (my wife would say, thats not tan, thats taupe, get it right ) all around the electrode, but I can see the electrode is all rounded off and probably shorter, I did not check the gap.

I see these bosch platinums with the four electrodes available. I'm considering these? They are bosch, in there now but I cannot recall what the part number is.

Its a normally aspirated motor, 5 speed, its just turned 250,000 km recently. We're a quarter the way to 1 million kms.....

With the non turbos you require a different plug to the turbo cars. Multi electrode plugs which are matched to your car type are fine.

The OEMs for non turbos are multi electrode (3 in fact)

Are these the correct type?

Non-turbo spark plugs

Yes, those look lie the Volvo plugs for a non-turbo. I use those or Bosch coppers.

Little bit of carbon (if dry) or oil (wet) fouling on plug second from left. Not too bad though. Worth watching to see if it gets worse.

Help. I have replaced the PCV on my 96 850 wagon (non-turbo), replaced the manifold, and tightened all of the bolst except the one on the bottom next to the starter; that bolt refuses to go in all the way. There is a gap of about 1/8 between the bolt and the manifold. Though it took a few tries, the bolt seemed to go in smoothly at first but began seizing up about halfway in. I assume this bolt needs to be snug, but please advise if that is not the case and I don't need to worry about it. Given the location, it is extremely difficult to work with.

Do you have a swivel socket?

Is there a small metal bracket in front of that screw that is getting in the way? If so, remove it - it isn't needed.

HI Friends,

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.

Probably just an unseated injector or fuel damper seal.

Hello all: Here are a couple of things to consider when doing the PCV Repair. I have done a few of these and have found that the fancy OEM or aftermarket hose set which runs between the trap and the PTC nipple are the weakest link in the chain. I use 1/4" and 5/8" Fuel/Emission hose to replace this unit. It is a lot cheaper and does a better overall job. I also use a 1/2" copper 90 degree fitting on top of the trap with 3 hose clamps to make a nice clean no stress bend for the 5/8" hose connection at this point. There is plenty of room to do soft bends following the OE routing for both hoses without kinking. If you want you can drill out the PTC nipple at both ports to enlarge them (I did this) however I did not notice any change by doing so. 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
