Pcv Write Up

[JBVolvo]

Nice job. Pix are worth a thousand words.

I appreciate the time it takes to do a job and stop to take pix and make notes as you go for a writeup.

Then taking the time to do the actual writeup with the pix. I've done it myself for several vehicles, so I know it can be a PITA at times when you could've moved much more quickly through the job if you hadnt been concerned about the writeup.

Thanks for taking the time to do so to help others.

I'm sure it'll assist many others in the future, and you probably learned a lot from the process.

One point that is probably very obvious to most (but not necessarily to all), is that your writeup is performed on a Turbo, and tubing will be slightly different for a NonTurbo. You may want to note that in the start of your procedure.

I thought about putting something like that in just wasn't sure how to state it.

Is there other service non-turbos need like the flame trap?

Yes, its not the same tubing also.

Just state it something like this:

"NOTE: This PCV procedure is being performed on a (year) Volvo TURBO MODEL 850. The Non-Turbo procedure has different PCV routing, as well as a "flame-trap" that the Turbo models exclude, and therefore will require slight adjustments to the shown procedure.

Here's the images for both later 850 models (its different for the early 94/95s.

95-97 Non Turbo routing:

I'd show those pictures but the turbo diagram is wrong. If any of you have missed the thread on this, it's worth looking at...

That's why I recommended taking a picture of the tubing before anything is disconnected and replacing it accordingly.

How is it wrong?

Really nice job on the write up. I read it through and think you have incorporated just about all the important info. If somebody reads this carefully and follows the advice given they will save themselves a tremendous amount of time and aggravation. I agree with the use of the ramps. I have the same ramps and made pre ramps by slicing a 6X6 with a chainsaw to create the slope.

This definitely needs to be pinned if for no other reason than one can't use a 3 letter search term such as "PCV". Maybe you could work Crankcase Ventilation into the subject line?

Tube 15 and fitting 6 in the turbo diagram should be reversed to the trap.

Excellent point. I'm always pissed (*and never seem to learn my lesson) when I do a search for a 3letter acronym and come up with an error message.

I'll inform Nick of that. I actually had to redraw the NonTurbo PCV drawing they had up before as well for a few similar errors.

I'll let them know and they'll probably fix it soon. Thanks

I find the google appliance at the bottom of the page to be a great search tool. And you can search a 3 letter word like PCV!

Thanks, who's Nick?

I've posted a write up from the notes and pictures I took while replacing my PCV yesterday. If you have a few minutes I'd appreciate it if you could take a look at what I've got and give me your feedback. Once I'm comfortable with the write up I'll post the it here if that's okay with the board admins?? Or I can just leave it where it is.

I tried to be thorough, perhaps too simple at times but this reflects all the things I had to work through and figure out so I figured someone else might gain from what I learned.

Please correct me if I've misidentified a part or hose I'll correct it online as I get them. I could use some help in step 5, what are those 2 little hoses? Probably didn't need to disconnect them but I wanted to reduce any snags I might encounter as I moved the intake manifold away from the block.

Thanks!

Awesome write up & superb clear pictures!

The two lines are both part of the EVAP Carbon filtering system; see htis pic from the vadis catalog

this Vadis pic from the design & function (rather than the parts catalog) section clarifies the debate over the porting of the center hose to the intake bellows.

How is it wrong?

For a point of reference I had this done at the Dealer in August 2006. Hoses, couplings, oil trap, breather box and seals. $613 total $467 in labor.

Due to the extra pressure of the clogged system, the oil dip stick kept being pushed out.

Looks like you can save some serious coin doing this yourself. Time is money and I didn't have the time or guts to try this myself back then.

But I am getting braver. Just replaced the odometer gear and pulled the ABS control unit to be rebuilt.

Next is wires, plugs, rotor, and cap.

Thanks, this has now been noted.

These diagrams and the hose connections were discussed in this thread as being backwards and incorrect.

I reinstalled my hoses the way the original hoses were installed which is opposite of the way those diagrams indicate!

Hi I just finished doing the same job but on a normally aspirated '98 S70.

Re your write-up change the wording to 'Remove the oil trap mine had 2 bolts securing it to the block (D)'.

I removed the old oil trap with the original hoses attached and off the car attached the new hoses to the new trap and was able to use the Oetiker clamps on all the connections because of this. (I see you had to use a worm type clamp on the hose going up to the cams because of limited access once the oil trap was attached to the block).

Also no reference to any diagram is necessary if all the new hoses are attached to the new trap exactly as the old ones were.

Another point of interest is that in the kit which I got from FCP Groton, the short hose that goes to the block at the bottom of the trap was a metal cylinder with a ribbed rubber insert so that it just pushed onto the 2 nipples (block and trap) and thus no clamps were required.

I also used a thin smear of 'O' ring grease on all nipples to make it easier to slide on the hoses.

I see you talked about having a magnetic pickup tool with you for good reason as I managed to drop a bolt (twice) into the depths of the engine when almost finished the job (and thinking I would have to remove the manifold again to retrieve it). Next time I would use a blob of gum or blue tack in the end of the socket to hold the bolt there whilst starting it in the hole.

I thought they were referring to this pic

which is backwards of the design & function pics...
