Cometics seeping after winter Since I took my car out from winter storage, it's been one thing after another. The latest adventure started last night after I did some tweaking on my idle, took it for a spin and put it back in the garage. I smelled coolant. Popped the hood and look around the best I could, it was pretty hot, and didn't see anything. I got up and noticed my driver's side exhaust pipe was a little lower than the other, I'm **** that way, so I got out my wrenches, lay on the ground behind the car and started to move the clamps around. That's when I noticed the smell of coolant in the exhaust pipe. The passenger's side didn't smell of coolant, but it is there in the driver's side. I checked the head gasket under the headers and it was wet, but not pooling. I pulled the plugs and they were all fine, maybe a little white, but not bad. And the oil is fine so it hasn't gotten to the crankcase yet.
I reused the cometics after I pulled the heads the second time for more work. I put them back on dry.
Just wanted to report this because I've answered some posts in the past that I've reused them with no problems.
My advice now would be to buy new ones, or at least spray them if you remove them.

Good luck.
Good luck.
We are having the same problem with those gaskets also. We haven't reused them, they were brand new and are have the same problems as you stated. What's the real deal here?

FWIW, I beat them up little because I used them as spacers when I notched my pistons, so they were on and off quite a bit. No big torque settings, just snug, but I should've listened to that guy on my right shoulder when he told me to buy new ones, not the guy on the left one telling me to screw it. I'm pretty sure I caught it in time, but an oil analysis will also help.

I re-used my Cometics. I use copper spray sealant and I have ARP studs... no issues so far....

How was your clearance?

How was your clearance?I'm running the AFR's with ARP studs and no problems with clearance. Although you got me wondering if I should get new Cometics when I put my 224/228 back in with Morels. I sprayed them last time with great results, but I'm wondering if I should do it again or get new ones.

. Yeah, now he's telling me to get studs, AFTER I ordered bolts. What's a guy supposed to do?
