Coolant leak inbetween head and block.

[mechanixrds]

I've gone through two head gaskets at this point. One with the new head and un-machined block and the second with the same new head and machined block. Same results both times. I've thought about putting on a new OE gasket but, to be honest, I don't want to take that gamble and be in the same position as this is a warranty job.

Here are the links to the videos:

Original failure
{video links removed.. they do not work.}

After block machine work with cooling system under pressure.
{video links removed.. they do not work.}

Both times with a new gasket.

Curious, why do you say to throw away the block if it has to be decked?

As far as aftermarket parts go, I've used a particular brand of in-frame kits, cylinder heads, and other components for close to a decade now and have never had any issues with them until about six months ago.
