Just got my new block, possible problem. I want your opinions
ok, just got my new Darton block from JD's. Aparently it got damaged a little durring shipping. There is a very slight scatch on the deck, and I was wondering if you think it will affect head gasket sealing capabilities. attached are some pictures of the scratch. I honestly think it will be fine with a small amount of sealant like you would use normally w/ these MID blocks when using a normal headgasket. BTW, we are using a cometics MID specific gasket.

I would clean it real good maybe scrape it with something sharp and put in some JB WELD but make sure to level it with deck surface maybe with the sharp edge of a razorblade held at a 90 angle,thats a pretty deep scratch man!!

I will tell you wright now the cometic gasket will not seal that.I sell the cometic gaskets and have used alot of them you must have a dead flat serface with a ra finish of 50RA or better for them to seal.The black coating that is on the gaskets is a thin layer of vinton rubber .001 thick it is for cold sealing it will not fill any grooves or scratches.

came on a pallet.... JD got it from steve @ race-eng... I've spoken with steve and he feels that some of the locktite 515 or 518 flange sealant will do the trick.

Well you can,t deck the block as it probably it cut as close as it can be you weld it because of the heat it is a water seal problem not combustion,JBWELD will hold on the aluminum.If it were mine and it was the shipper,s fault I,d make them replace it or is it a problem from machine shop???Anyway how would you fix it any better ideas?????????????

Too high dollar of a setup to trust ot some sealant.

need to measure it yet. and no, there was nothing covering the deck, other than the plastic. The way the block was shipped makes me wonder if I will even be able to get anything out of fedexfreight.
