After my recent mishap i went to a diesel shop and asked them what an estimate for pulling the head to get the extension that i dropped out. The guy gave me a price of $4000 to $5000 including parts and labor to remove both heads, he said at that point it would be best to do both because your in there already. I dont know enough about these engines to tell if thats a decent price or if hes trying to screw me. So if anyone could shed some insight for this noob that would be greatly appreciated. If anyone knows of any good shops near central illinois that be nice. Thanks again.
