Is there a shortage of 216 Engines?

Hi Gary

Could you tell us again what you have tried to determine where the water leak is? The reason I ask is that there are not a whole lot of places to have an internal leak. May be some one will have a bright idea about a simple check and hopefully a fix.

Short of disassembling I have done air pressure test check on blocks and heads before taking them to the machine shop to be magnifluxed. In this way found the obviously junk blocks.

Besides it would be a shame to find a new block only to discover it was the head that was the culprit.

Now as to your block casting number 839253 it doesn't show up in any of my casting number source list all US lists, no surprise, now who in our little group has found the online list of Canadian GM casting numbers?

Cheers Phil
