2000 S70 PCV Replacement

coffeysm · Post by **coffeysm** » 24 Dec 2013, 13:44

So, I bought the PCV kit from FCP about a month or two ago. But, didn't have a chance to start working on it until last night. I had to change the water pump and timing chain in my G35 and after doing that I think I can tackle this easily, lol.

Here are some things I noticed on my car specifically 2000 S70 N/A.

There is one fuel line that is a disconnect line and if you don't have the tool and it's 10PM at night it's a pain! I was able to disconnect them using two picks from a kit I have. You basically stick them in these two small holes one each side, pull the tabs out, and then push the connector (all at the same time) and it separates. But, a good amount of fuel will spill out if you aren't careful.

I disconnected my throttle body completely.
Jacked the car up slightly to easily remove the lower manifold bolt and oil dipstick tube. I used a couple of extensions and was able to maneuver the bolts in.
My PCV system was like 99% blocked up! The lower port was filled completely, the upper port was about 90%, and everything else was brittle.
The intake manifold has significant carbon buildup and so does the intake ports on the block. It's going to take a little longer then normal, since I have to clean all this gunk off. I'm probably going to take the manifold cover to a DIY car wash place and clean it off.
Overall though this wasn't that bad of a job; I'd rather do this again then changing my lower control arms or tie rods.

I also found a 10MM wrench that had fallen in the engine bay from when someone else worked on the car, lol.

Have a read of This from when I did the same job on my N/A V70 (same engine) make sure you check the lower port that the PCV tank connects to is clear by trying to blow through it using a length of 5/8" hose.

If you want to clean out the manifold soak it for a few days in kerosene, If you can't get jet fuel consider soaking it in paraffin which is similar - Mike

I would not recommend trying to clean out the LARGE intake ports, just small blocked holes. You wouldn't want things to fall into the valves or piston area.

Thanks Mike I didn't see your post and wasn't aware about that hose trick. The car is still apart, so I will do that when I get the chance.

Just want to say thanks for your videos; I have watched a lot of them.

I plugged up the holes and cleaned up as much as I could without having to worry about crud dropping in the valves. They were pretty bad I'd say there was about 1/4-1/2 of built up junk on the large intake ports.

I blew into the PVC system with a hose and it was clear. I took the car for a test drive and everything seemed fine and then parked it. Then today I am having some serious problems so will probably start a new thread now.

*Actually just figured it out. The fuel pump relay is bad; I hate this you fix one thing and something else breaks!

Last couple of months: PNP, Window Master Switch, Non-functioning Rear Pass Window related to Master Switch, Heater Core, Heater Core Hoses, Water Pump, Front Brakes, Engine Mount and now Radiator Leak besides a broken CV Boot from a year ago and Alarm System rebuild in the works

. Love the car but if it weren't for MVS I would have just cut my losses and gotten rid of it as it can be a money pit if we couldn't tackle the work ourselves.

Blessings,

I know I have replaced a ton of stuff the past few months. Same thing goes for my G35; I just did the timing chain and radiator replacement on that and saved myself at least 1500 in labor charges. I have a few issues with the Volvo to tackle then hopefully (ABS, ETM and/or PNP) it will be at stage 0 finally.

The fuel pump relay though scared the crap out of me! The car literally stopped working going like 40MPH and it took a lot to steer it into a parking lot safely. Then had AAA tow it back to my house, so I could verify it was the fuel pump. I ordered a replacement from a dealership today.

It's the burden we bear for not driving a dung-box.

I just did the Admirals rear brake pads on her BMW which was quoted at 600 USd at dealer. I did it in 2 hours in the driveway of the upstate NY house with 40 bucks of parts and 10 bucks of brake fluid.

Only problem was prying the T5 back from the Admiral...."Gee...this car is fun"

I recently purchased my T5R and done quite a bit of work to it... all timing and water pump components replaced, tune up, pass side cv axle, oil change, cooling fan, installed double din dvd, front tires, power antenna, projector HID headlights, waiting on drv. side cv axle in mail, and still gotta do the pcv... cars are needy but fun..
