Customer Question

I have a BMW D7 with a cracked cilinderhead. The whole engine is overhauled, but the cilinderhead is still out of order. Welding is more or less impossible. Is a new or second hand cilinderhead to deliver ?
I live in the Netherlands. The engine is modified with an extern alternator. and builded in a classic wooden Nordic Folkboat.

Hello,
Thank you for allowing me to assist you, my name is ***** ***** I will be happy to assist you with your concern today.
If a proper machine shop cannot weld and work the head as a repair then it does require replacement. To locate the correct head per the application would require the casting numbers from the old cylinder head, to which with that and the exact full engine model number one could then attempt to search and locate a replacement cylinder head for you. Getting one to your area however may prove a little harder then actually finding a replacement.
