Can I reuse valve cover grommets?

Featured Replies

Long story short back when I was chasing misfires I ended up finding out it was the plug wires but the rubber part that goes over the ceramic part of the plug broke off and I had to be creative (out in the rain) to pull that rubber part off to get the new wires on..

 

OK so at that point the gaskets had only been on maybe 4 months or so, however I used DNJ gaskets and I've got to replace it again but I wonder if it's ok to use the grommets? I just need the gasket for the RH side and given my leak rate I'd like to do this sometime this week..

 

btw I think the bolt sizes are 8 or 10 mm?

I buy the felpro kits that come with gasket and grommets myself.

 

I'm not a big fan of doing things twice or smelling oil so I error on the safe side.

But the felpro comes with both sides, I just only need the right side.

i would re-use them. they can go bad from age, hardened and cracked, but it's not like they get crushed where they wont work again once installed. If thay are still flexible, they are still usable.

 

If in doubt, put a little ultra grey on them.

Oh well I ended up just ordering a set that includes everything

 

I'm almost certain the bolts are 10 mm right? I know the lower one closest to the firewall the only way to get to that one is with a box wrench at least from what I can tell.

10mm is right.

 

take out the pitch bar and loosen a motor mount and you can jack up the motor for more clearance if need be.

I use a snap-on or gearwrench "rotohead" ratchet and basically have the ratchet head in the palm of my hand to make sure I don't overtighten them. They bottom out all of a sudden and the torque spec isn't much.

No the torque spec is not much at all I don't have the service manual in front of me right now but I think it's pretty low between 7-10 ft.lbs and I want to say more around 7.6 or so.

It's a shouldered bolt so it will only allow so much squish on the gasket anyway. hand tight and snug is all it needs to be. Overtightening can cause the bolt to break, but does not afford more clamping force on the gasket.

You can individual order them from rockauto, as I had to do recently. I reused a bunch on the EJ20G engine I have, but it has been sitting around for about 8 years without being used. I ended up having a lot of those grommets leaking.

Saw that but I haven't used rockauto in awhile now I kinda just use them for part numbers and copy it over to amazon, if rock auto did not charge for shipping at each warehouse it ships from I'd have no issue but it adds up..

 

Plus I wanted to take advantage of my prime membership at Amazon so I figured why not.

torque spec on the cover bolts is around 4 ft-lb, bolts might bottom out less than that though. eight bolts under the cover spec at 10 ft-lb.

Gotta love your car when working out in 25F wind chill temps early in the morning..

 

painless I noticed the bolt at the lower cover near the Crossmember was loose but this kit was better then that DNJ one I got from Rockauto.

wow good thing I picked up a set.. the drivers side was leaking as well.. stay far away from DNJ gaskets from Rock auto!

 

I hated to do the drivers side because of that last bolt near the cross member is a pain with a wrench.
