Problems. :angry:

The old PCV valve is plastic, two parts - the valve/casing and the 90 degree bend that goes into the hose. The "hose" is actually hard plastic with about a 2" rubber piece on the end that connects to the PCV valve.

The 90 bend piece WILL NOT come out of the hose.

The problem? The replacement I bought at Advance Auto is also two piece, the PCV casing is metal, the 90 bend is plastic. But softer plastic than the hard-as-nails original. I figured what the heck, i could just use the new PCV valve and the old 90 degree bend piece, right? No go - the new metal valve has a bit of a lip on the top that, while fitting fine into the softer plastic end piece that came with it, WILL NOT fit into the old hard plastic one. It doesn't have any give to it at all.

Is there a trick to getting that old hard plastic 90 degree bend piece out of the hose? It seems locked in there good....like there's a fitting or something under the rubber piece that's hooked to the vacuum line.

I've also just finished replacing the front 3 plugs. What a PITA. Had to drop the electric fan to get a socket onto #5 & #6. I'm taking a break before I go out and try the back 3. That looks like its going to be a treat..... Remind me, if I ever meet him, to kick the guy that looked at the 3.8, then the Taurus and said "Sure it'll fit" in the nads. Hard, fast & repeatedly. :curse:

BTW, the Motorcraft plugs I took out (44C - copper?) looked to be originals. Not cool at 80,000 miles. :unsure: #4 had a very slight green tinge to it. If that means what I think it means this board might be short one Taurus pretty soon. There's no way I'm going to spend $$ to replace the timing chain cover gasket AND put new head gaskets in it. I'll let you know what #1 looks like when I get around to doing the back 3 later today.

Try some penetrating spray on the hose, it should come off. If you can rotate it slightly, that will help as well.

get a towl and lay accross the intake when you try and get to the rear plugs. some old vacume tube will help out trying to the the new plugs screwed in.

Bob: I can rotate that piece but that's about it. I don't have any PB Blaster but I can pick some up on the way home from work tomorrow. The old PCV valve still rattled when I shook it so I just plugged it back in for now.

crackhead: I actually used a couple of sheets of cardboard I had in the garage - laid them across the top of the motor and crawled on top. My right arm looks like I dragged it through a thistle bush, though. Ouch. But, hey! They're all in and the car purrs like a cat. Wish I would've gotten your tip about the vacuum hose to get the plugs in before I did it, though. It would've made it a little easier. :)

I'm a little worried - the #1, 4 & 6 plugs have a slight green tint to them. I don't currently have any other signs of head gasket failure, though. Should I be worried?

Next weekend's project(s): power steering pump & tranny filter, tranny pan gasket and fluid change.

thanks, guys! :)

If you could post pics of the plugs, that would help a lot. Also, are you losing any coolant at all?

The PCV, if it still rattles, you don't need to bother changing it. :thumb:

I know that if it still rattles its still technically good but boy does it look NASTY. :p

I don't have a digital camera but might be able to borrow one sometime next week.

Or I could mail 'em to somebody if that would be easier. I tagged them as I took them out.

Losing coolant - some, but it is leaking from the timing chain cover. Very slow leak. A couple of drops a day if driven regularly, if I let it sit for 4 or 5 days then there's a spot about 2" in diameter on the garage floor. I hadn't checked the level for 3 weeks and I only had to put 1/3 cup in to get it to the full cold mark this morning.

I had it pressure tested when I first noticed it earlier this year and the estimate was around $500 to do the job, a little more if they replaced the water pump at the same time. I put some Bar's Stop Leak (the aluminum stuff) in it a couple of months ago.

I'm trying to decide whether I want to try & tackle that job myself or farm it out. We'll see how next weekend's projects go first. ;)
