Has anyone done 5V 4.2 valve cover gaskets, cam seals?

[redneck truck]

About to start the valve cover gasket, cam seal, cap job and it looks like a daunting task. I've already got my intake duct, coolant reservoir, and all the front vacuum lines out, the timing belt stuff is almost gone, and the car is in service position. I've done valve cover gaskets before, but they've never looked like this. Any helpful hints would be greatly appreciated.

Its not that bad, My first was a Touareg, ( same 4.2 v8 ) I must have double checked it 100 times!!!
Engine bay is a little more tight, be careful for the alternator, if I recall its also water cooled, and the engine mount bolts upto it.
make sure you have the Bentley, and the factory cam lick tool and seal installer's
Dont forget new seals are PTFE and need to be installed dry, and not moved for 4 hours to set up properly.

that's the first mention I've heard of the PTFE seals and the water cooled alternator. Pretty sure the Touareg doesn't have the same engine - everything I've found says it has the AHQ, while my car has the AWN. I appreciate the reply though, and I'm pretty sure you're right about the tool and seal installers.

hey man, you need to put some sealant silicone at off of the low points for the valve gasket, via the bentley manual. Also, make sure you tighten the bolts down in the order they are supposed to be done. Are you replaceing the cam chain tensioner seals as well?

[redneck truck]

If the cam chain tensioner seals are the little half moon plugs that come with the valve cover gaskets, then yes. Please clarify. Also, do you know the torque pattern off hand?

there is also another gasket that goes below the CCT

I am right about everything, except the Alternator on this model being water cooled.
All 4.2 V8 5V engines with the cam belt are identical in appearance. they still use 4 cam seals, 2 cam plugs, 2 tensioner seal kits, and of course 2 valve cover gasket sets.
If you do not have tightening torques, buy a Bentley CD. thats one hell of an expensive engine to break. I own a VW / AUDI shop here in So Cal. If you need part numbers let me know..
Points to consider:
Be careful replacing tensioner seal kits, there is a fine screen that likes to fall out.
Please only use D 404 176 A2 sealant on the cam cover corners. Pure silicone based sealants can damage o2 sensors.
You don't have to remove cams from engine, they are a little difficult to replace the seal kits, but it lessens the possibility for errors.
PTFE seals are Teflon based, and must be installed dry, not like a common seal. If any oil is present IT WILL LEAK! They need a minimum of 4 hours to conform the the cams.
Also replace your thermostat when you are in there. based on my experience use OEM, or after market Behr, not Wahler.
A source for cheap cam lock bar, crank pin, cam tensioner compression tools etc is www.tools.vw.com The public can register to buy tools.
And unless I was mistaken, ART, AWN, BBD, AXQ, BHX, BGH, BGJ, and BFM are all the same 5V V8 motors. ( Phaeton, A8, Touareg, and of course A6)
Use blue Loc Tite on everything, and a good torque wrench.

All great information - I appreciate your response. Do you happen to have the part numbers and maybe an image for the cam chain tensioner gaskets?

here you go my man.

Just when I thought I'd bought everything I needed. If I understand correctly, the front cam seals need to be done with the timing belt, but the adjuster gaskets, plugs, valve cover gaskets, and rear cam seals and caps are a separate job. Is that correct?

[G Men 08]

you can do the front cam seals without replacing the timing belt, you just have to remove the belt and sprockets. But if you wanted to wait I suppose you could. Is your timing belt service near by?

[redneck truck]

My timing belt service is underway. The car is currently taken apart, and this would be a perfect opportunity. What I'm really wanting to know is, do I need to get everything done while the timing belt is off, or only the front cam seals? I'll get done what I have to while I've got the motor apart, and at a later date, tackle the oil leaks that don't require the timing sprockets to be removed.

When installing the cam seals, am I correct that they should be installed perfectly clean and dry, or do they need some sort of lubricant to help get them installed on the camshafts?

[G Men 08]

install them just as you took them out of the box. be sure they are nice a straight!! The passenger side one that I did started leaking on me.. Not the one behind the cam sprocket (thank god) I had to remove the valve cover and pop the seal cover back off, take the seal off, put it back on and so far it has stayed seals (knocks on wood).

I just inserted my photobucket album of all of the engine pics I took during the work I was doing on it.. Go ahead and take a looksie if you'd like.

Thread is in my sig..

come on man, like I said, if its PTFE, NO lube!!! its easy to tell, there is no spring behind the seal. Also it will come with an arbor, and in a sealed bag with a desiccant.
I hope you have a cam lock bar, and a crank lock pin.

[redneck truck]

well, then i guess they arent ptfe. they look like any other seal ive ever replaced. there is a spring, and they came in an open bag. i dont have the tools, but i will by the time i break the cam pulleys loose.

Hello hello? The forum has fallen asleep. Just posted three new how-to's in my google docs blog.
