Got the motor torn down and during the process was getting really nervous because there was a LOT of moisture in the motor from the blown HG.
But I'll be dipped, after a thorough inspection I can't find any block/head cracking, and the cam trays look useable.
Obviously machinist will have final say, but with the cost of spare block/head/cam tray this is a huge win and I am very pleased.
On the not so good end of things, the bores are rusty, and the valve springs are rusty which is obviously a huge no-no to use rusty sprung steel....... which mean I'll have to buy a set of springs, which likely means I'll upgrade, which will probably convince me to buy cams of some sort.
Regarding the cause for the HG failure, nothing stood out. There was red gasket maker under the cam tray which means someone was probably in there, so maybe just a HG job gone bad?
