Cylinder head damage
« on: 13.05. 2021 01:09 »
Just realised that some damage to my iron cylinder head is possibly worse than I first thought. The damage seems to be  fairly common as I've seen a few on eBay damaged in the same place, the timing side inlet rocker cover screw thread part has cracked. It's been welded by a previous owner though not very well. My concern is that it may have internal damage extending into the inlet port and thus effecting induction. I poured some brake cleaner into the hole which leaked straight out onto the fins, the corresponding hole on the drive side held the brake cleaner.
I've wedged and modged some chemical metal into the voids in the crack and the weld and it now seems to hold tight, but am I hoping against odds that this is the extent of the damage?
Opinions or advice as always, very much appreciated.

Hey GB
The Oxford dictionary definition:
Verb; to modge.  To stuff down into a hole with a knackered old drill bit until it squidges out the sides.
Apparently an amalgam of the two old English verbs mush and bodge.

Thank you for the clarification Minto.

What about the word 'wonged', pronounced 'wonjd'. That is, to squeeze the tea bag with a spoon to extract the most strength from it; "Give my teabag a good wonging please".

Thanks for that morcel of enlightenment Neil.
There should be separate thread for obscure terminologies and colloquialisms.

Struggling to imagine being in the pub at all. He'd better be a good mate..
