rusty spark plug!

anybody ever find this? the f#*&^% copper gaskets! i tq'd them after the first heat cycle and again before i ran a few weeks ago.

sorry never see that.

i saw it last year!

time to switch gaskets? Cometic possibly?

Thats my point..... Copper Gaskets are for top fuel, where the heads are dry and they are off every run !!

yep,at the time i did this the mls gasket was the "new" thing and i did'nt want to change.lol

Lee,

If you want to continue to run the copper gaskets, then go around each water jacket opening with a finger smear of RTV, before putting the gaskets on.

i did that last time and it did'nt hold long.i did'nt have trouble before i went to alky but i also have about 2 more points of compression now also.after i got the heads off it looks like where the o-ring comes together it pushes the sealer out to the water port but it never pushed any water in the overflow .i checked the rings and they're only .010 high so thats not a problem.this time i did heat the gaskets,anneal? i think it's called.it always leaks on the lower side of the block and the gasket is a little discolored or blue look'n.it never gets hot sooooo the timing is low,28*,but it runs best.any ideas?

i knew somebody would say it,just did'nt know who.

One of the problems I'm thinking is heat and expansion of the parts. I'm thinking the gaskets are moving around.

Need Heat in the engine.

Lee, are you retorquing the coppers a couple of times after the first few heat/cool cycle?

the first time i did'nt but have the last couple times.i even tq'd them again this year before i put the rockers back on,ran it one time and struck water,lol. it only had enough to rust the plug in #3 but 6&7 were not far behind.maybe it'll hold till after june or i'll be forced to put the big motor in!

their is a GM block sealer that alot of people use and swear by it.maybe someone knows the part # or what to ask for at the parts counter?

i always put ceramic seal in it.one head had a plug hole welded up and redone when the heads were new and water pissed out on the ground! the ceramic fixed it and i'm sure it helps the gaskets out.i think i've read about the gm stuff,pills you just drop in the radiator i think.

this is the sce gasket i took off last year,look like it's been hot to me.

imo the color with heat disapation and reliese is kinda normal with copper.it does look to have taken some heat but the gasket didnt fail,their is no evidence of compression leakage or worpage.
