C15 head cracked between intake valves

those cracks are normal in that area. but how deep they are is the question. I sent my head to cat for them to check it and resurfacing. cost about $500 to inspect. came back ok.

 

I'm not sure as I am not familiar with the C-15 head but have often seen it on heads.
Some makes and models are more prone to it and if the cracks aren't to deep they seem to look worse then they are.
I however could never get used to putting a head back when I knew it was cracked.
I saw some manufactures (Mercedes) on some models machine a half moon type recess between the valves on later models of problem model types.
I believe one of the leading causes is over torqued hold down nuts on injectors on some types of heads.

 

if your going to reuse the head, I would still have it resurfaced instead of just cleaning it up.

 

My only fear is that the valve seat would come loose. But I have sent probably 75 cat heads back on with those cracks that cat says are ok and never had problems yet.

 

If You Werent Burning Wate And No Fuel InYour OilThey Probably Are Just Surface Mine Had The Cracks An Was Okay But Was Warped So Had To Replace

 

Ive got trucks that have put 500000 on the heads after I reinstalled. They were cracked and cat said they were fine and so far so good.

 

Justin home many miles were on your engine? My 2ws spun a rod bearing also with a million miles on it. It seems like I'm hearing this more often in the last few years. My head was cracked in #6 and CAT said they would accept it as a core but there was a upcharge for the exchange head. I think it was going to be 2500 exchange.
