Gen 3 valve cover gaskets

[bacernate]

Any gen 3 valve cover gaskets out there?
Any other thoughts on getting them to quit leaking onto my exhaust manifolds? Silicone isn't in my vocabulary so don't suggest it please.
This is my dd so a fast turn around would be appreciated.

What happened to your stock ones.. did they break?

 

[SHOZ123]

I have a set. New or used?

 

[bacernate]

I need new ones. What good would it do to put hard brittle used ones in?

 

[bacernate]

Do they come with tube seals Paul?

 

[SHOZ123]

Why would I keep old hard gaskets? Yes they have the tube seals.

 

[bacernate]

pm me a price shipped to 80504. You said used so I assumed they were very old.

Paul has a secret recipe to renewing those old brittle valve cover gaskets.

Not something I want to do twice though. Replace the gaskets 8 new plugs and coils and clean the lim and remove the butterflies and never worry about it again. Unless I happen to keep the car another 4 years, not likely as Ive got the itch for something with some real power.

I had to replace mine a year or two ago because oil was dripping on the rear exhaust manifold. I ended up finding a set on ebay. I did replace the plugs while I was back there and clened the intake runners and tank. I didn't replace the coils though. Probably would be smart to at least do the rear four while you're in there. I would recommend that too.

Re the coil packs....what is the rationale in changing them if they're firing correctly and no misses? I understand there would be labor savings vs waiting until one or more failed but heck I'm still running original wires and coils on my Gen 2 94 with 98K on it and no issues. I'll be having the cams welded soon and if there's a real advantage I'd consider doing the coils too. Your thoughts are appreciated.

Your Gen II shares nothing with the Gen III as far as ignition goes. Gen III have no plug wires. The COP are a known failure item. Some people replace the rears all at once to save the labor of removing the surge tank.

Also, you have no need to weld the cams on your Gen II

I'm an auto tech by trade, so doing stuff more than once isn't my idea of a good time. I barely can make time to work on my own stuff as it is. Case in point, I have an Infinity in the shop right now with a dead injector. 5 hours to pull the intake so it's getting all 6 injectors and valve cover gaskets and also plugs while I'm in there. And yes the injectors on a Nissan product are like our coil pack issues.
The only thing you need to worry about on your gen2 is the spark plugs tube seals leaking oil into the tubes and ruining your plug wires.

Rcadell,

"Thanks for your insight. I've got both agen 2 and gen 3 so I'm having the cams welded on my gen3. I was concerned about the reliability of the coils on gen3 for that reason. Just seemed strabge that the reliability of the coils on gen 3's requires preemptive replacement. John

It doesn't. But everything wears out eventually, and if you are already opened up to the back, and they are getting old, it just saves effort eventually down the road. How long down the road is another question. I am still running the originals 11 years and 190K or so down that road.

Also suppose your in the middle of nowhere when your car starts misfiring, do you tow it? or do you keep on trucking till you get home? Most people keep on going and then you stand a very good chance of killing the cats.
It all goes back to why do you do maintenance on your car at all, to make it last longer.

Once you replace rear coils you'll understand the desire not to do it multiple times. It seems the overseas suppliers are making the coils more affordable, so a rear set of 4 doesn't have to cost ~$250-300 anymore.

 

[JohnKay]

Discussed with NESHO and and decided to rotate the coils....worst come to worse and I can pick up a set of Asian coils for about $100.00 on Fleabay.

One missing won't hurt your cats. and if it is a dead miss the PCM will shut down that injector to prevent raw fuel from going out there anyway...

IF it has a miss drive it until you get a chance to fix it - no big deal actually. Sure I wouldn't condone doing if for several months. but as cold as it is now If a miss started up - I'd wait until the first good mid winter warmup but if that never happens the end of March is fine with me.

I only found valve cover gaskets at the dealer. Paid $97 including tax. I bought them ahead of time before I took my covers off to weld the cams. They had a very very small leak on bank 2 toward the left side of the car. Not much oil, just a bit of gunk where a leak would spring at any moment. No leakes on bank 1, and I was very surpised at how good a shape the gaskets were in. No cracks and very malleable, first set of valve gaskets I removed in one piece in quite some time. But like many of you, I hate doing a job twice because of carelessness. Chucked the old and in went the new. Hated that it cost $100, but I already planned for it.
