Head cracked

Postby mhuppertz » Wed Feb 20, 2013 9:11 am

Machine shop just called and said the head is cracked into the injector hole on every cylinder!

Time for a new one.

If you buy a new head,break it down! makes sure its been built correct and is clean inside.

TRUST BUT VERIFY!


Good luck.

I've got one but shipping would be outrageous! Goodluck finding one. It seems like stuff always breaks when money is tight!

I got a brand new (loaded) head for $430 plus $88 shipping. Could have been a lot worse, but it still hurts!

I expected to pay $150 for shipping! It worked out. Kicks the 440 '69 Dart project down the road a bit farther though...

Shipping can be had pretty cheap if done right, especially businesses that do lots of shipping through ups.

Last year, I shipped a t-case from Idaho to Florida for $68

Every B-series Cummins head has cracks to the injector bore.

It's hardly ever a problem.

It is a problem though, when those same cracks extend on over and into the valve-seats. :(

Find out where those cracks are.

Too bad you didn't know it when I visited, Mark.
I certainly would have brought you one while I was there.
