Valve cover/spark plug tube gasket help
So I took out the Z from storage and noticed it was smoking a lot from my catch can breather firstly, so decided to take it all apart and removed VC's and found a good amount of oil in the spark plug tubes mostly passenger side. I think it's the spark plug tube seals as I have no exhaust smoke. Can this also be causes the excess smoke from my breather on my can???

Whats the most "UPDATED" method to fix these leaky tube seals?

Buy new valve covers is the only way I trust it and even then I'll have to do it again in the future. Nissan made some good money off me fixing that problem
Then to make it even better. I still have that odd step/misfire when cold. I'm pretty sure it's one of the coils |
^Thats what I was afraid of... Only to have the same problem down the road...

You can get new O Rings from PartsGeek and replace them. It does involve a 1 7/8" hole saw to cut the old O Rings out of the valve covers. The baffle plate will now no longer hold the O Ring in place so you have to put silicon on the O Ring and press in place. Let the silicon dry and then reinstall the valve cover. O Rings cost 16 to 18 dollars, better than 200-300 dollars for new valve covers. Hey it's your money but for a minor bit of work it is worth the savings to me.

It has been pointed out that this fix was tried and failed in the past. There was a reason the baffle was glued firmly in place to hold the O Rings. The silicon will not glue the O Rings firmly in place and this fix will fail. On the other hand the fix is a good idea just use the right glue and clamps and the sucker will never come back off , a one time fix though.

dorman makes valve covers now, check out rockauto or your favorite parts store. Or if you are more inclined to oem try a vendor or dealer depending on the discounts you find.

Might be a little more than you want to spend but there's some billet valve covers being made for the VQ now. Might be worth looking into.
|
^I wouldn't mind actually so that I dont have to worry about this happening again. Most of us for years been wanting this for a long time... Who is making them??

Company called SuckerPunch Motorsports. I posted the pics in another thread in this section of what they looked like.
