1998 V70XC Stalling (misfiring) while accelerating Topic is solved

You can definitely do it. It will take time though. depending on your selection of tools, and familiarity 2-5 hours. Make sure you go through the process in the tutorials first, and get ALL the supplies you will need. It seems like a lot of removals to get to it, but it's just following the sequence. You will be proud of your accomplishment, and more confident in your car afterwards.

I agree 100%. PCV refresh is a long job, but it is just taking things off and putting them back on. Nothing technical or tricky, just make sure you do all the steps. Don't forget the intake manifold gasket.

Make sure you have some ratchet swivels and extensions. A few of the intake manifold bolts are what could charitably be described as "inaccessible." Not altogether impossible to get too, but some colorful vocabulary required. Also, remember that you do not need to remove the lower intake manifold bolts since they are really just locators that the manifold sits down on.

When I watched the FCP DIY video I got nervous when he started in on the intake manifold. I did the radiator a year ago.... Can't be any worse than that....

A set of these will make the manifold removal much easier:

... and maybe a 1/4 inch universal joint as well.

Don't know. Never done a radiator, but the PCV isn't too bad as long as you go slowly and are methodical. A helper to provide an extra pair of hands can be quite useful.

Just as a follow up, I completed the PCV job on Friday afternoon using the kit from FCP. The project went pretty well (~5 hours). The wobble socket extension set certainly helped. No more smoking dipstick and there is suction being created when a latex glove was placed over the oil filler. Also not getting the extremely foamy oil on the dipstick. The lower passage on the block was almost completely blocked with gunk and there was foamy oil residue throughout the entire hose running over to the PTC nipple.

I have a couple follow up questions: When I disconnected the hose from the PTC nipple it was completely gunked up. I cleaned it out the best that I could with a small screwdriver without removing. In retrospect I should have removed. How long will this take to do? What should I clean it out with?

Secondly I'm a little concerned that I got everything hooked up in the right spot, specifically the fuel line and also a smaller hose that also hooks up to the manifold (not sure what it is?). Does it matter if these are reversed?

Lastly, and this could be completely unrelated to the system...when I get off the freeway for example and am stopped at a light, I hear 3-4 intermittent popping/clicking(?)(2-3 seconds apart) sounds coming from under the hood (drivers side). Any ideas on this? Thanks!

(1) When you say "the hose on the PTC nipple" do you mean the small diameter hose, that hooks onto the side of the PTC? That hose you really should just replace any time you service the PCV. The other end of it hooks to a small metal nipple on the passenger side end of the intake manifold. Do you remember hooking that back up when you did the PCV? You can replace it with 3-4 feet of generic, 3/16 rubber vacuum or fuel line.

(2) This will matter, not sure which lines you are talking about. Check the vacuum lines diagrams in the MVS repair database.

(3) Hmmmmm no ideas.

I did hook up the smaller hose. It comes as a complete hose assembly (one for the box and another for vacuum).

...

This is why I asked about the small hose. I thought you meant the small hose was gunked up. But you mean the PTC is gunked up? I am guessing it will take you about 15 minutes to remove the PTC, 10 minutes to clean it, and 15 to put it all back together.

- disconnect MAF clamp and TCV, and remove air box
- disconnect clamp holding snorkel tube to turbo. this one is hard to reach I use a long extension from above and basically lay on top of the engine, looking down at the turbo.
- pull snorkel tube up and out of engine bay (be caraeful about attached lines)
- disconnect hoses and remove PTC, it just pulls out
- clean PTC with carb cleaner in well ventilated place, you can get it completely cleaned

- Reinstall PTC using a small screwdriver to push in the rubber edges, it seems hard to do but is actually very straightforward with a small screwdriver.

- reinstall snorkel tube, etc: button it up
