Heard a ticking noise, opened Valve cover and could smell, see, and feel fumes coming for the first cylinder. Any idea what is going on? https://youtu.be/cmZtexq6SJ0
Yes I have seen them burnt but the heads were scrap due to excessive warp/cracking & heat distress so they were unusable anyway.Dennis, have you seen this issue damage the sealing surface to the point where a new washer and bolt won't fix it without re-machining? I have not, but have seen exhaust valve seats destroyed for similar reasons. Maybe something to look carefully at before re-assembly
Dennis, not always, but sometimes I can expect for your writing style to bring a smile to my face, amidst what at times is laborious reading on this forum. ?lindenengineering; said:...like the sugar plum fairy
Actually seal (copper washer) and bolt replacement is MANDATORY!!!...I take it that it just makes sense to replace all the washers and tie down bolts?
DaveUm... no. Not normal, but how bad that is is beyond my pay grade.
I’d suspect something like a cracked valve cover, but didn’t think coolant circulated above the head.
Is it a productive leak (volume under pressure) or a weeping?
Are you the first one in there? (is the sealing surface down the bore still textured or has it been cut smooth by someone?)
Possible that someone stripped threads then botched the subsequent repair...
(ever seen this, Dennis??)

Do you happen to have a link to the parts needed or links to instructions? Never done a nutsert before, but want to get the injector seal fixed.Dave
Yes i have
Generally it means someone has been in there and done some sort of remedial thread pocket repair/ recovery drilling too deep into the head casting and penetrating the cooling jacket.
Its recoverable in some cases by inserting an extra long 6x1 nutsert into the hole plugging the end with Vic's favorite "gobwack" JB Weld!
