When replacing valve cover gaskets is it best to use them as they come from package or oil them up?

I always run a thin film on oil filter gasket...

 

I think its more about getting the right torque on all the bolts vs whether you are oiling the gasket or not. I bought a lower range torque wrench just for this job.

 

X2. Install them dry and torque from the outside-in. Applying oil to a filter gasket only allows for easy hand removal. Doesn't do anything for sealing.

 

I would suggest you torque the nuts in a criss-cross pattern, starting in the middle and work your way out.

 

Whups! I was apparently really tired. I meant to say inside-out. Similar to a sequence such as this...



Good save crg!

 

The Porsche manual uses a LOCTITE copper colored sealant on the gaskets.

 

Where does it say that? Can you provide a link or photo?

 

item 23 in PET 103-07


last year I did mine dry. no leaks


This year I added the sealant. I'll tell next year if any better.

 

I've been installing my valve cover gaskets dry too. Am curious to hear if lubricated is better.

 

I have always done mine dry and it just didnt seem right, I am going to use The specified sealer (Loctite 5920 Copper RTV) next time

Thanks for the advice

 

call me crazy but I always used a thin film of grease (axle grease or similar) on my VWs valve cover gaskets to keep them a) from leaking and b) easily removeable (and reuseable) without tedious cleaning. I do this now on my C4. Still leak free and easily removeable--I haven't tried reusing though...

 

It does show sealant in the PET. No mention in the factory service manual in the valve adjust or the engine assembly.

 

That's actually on that page of PET for the plug (#4) on the end of the spray bar (#3) and the plug (#18) on the front of the camshaft housing.

 

I've never heard of using RTV on the 911 valve covers. Silicone gasket lube, yes. Or a light grease, that sounds ok.

 

Thanks, Jason. I don't think I did any harm by adding a little of it to my seals. I do my valves once a year and inspect for leaks often so I will be on the lookout for any difference.
