I recently posted looking for a head to replace my cracked #14 and ended up finding a cream puff om603 complete. It runs like a dream and has zero blow by and is definitely the quietest om603 I've ever come across.

It currently has 217,000 miles on it. So my question is do you think it would be worth while to replace the head gasket as preventative maintenance? Or run it as is? I plan to replace a few other gaskets before I stick it back into my wagon.

Thanks, Jon

Run it as is.

That's what I thought. I figure when I do replace the head gasket it will be when this head cracks Haha
