Got this from itr head from a friend, he dropped the #1 valve. No damage to the top of the head.
I wanted to have it opened up for 83mm bore but didn't know if it was salvage-able (is that even a flippin word..ha.)
Thanks

Cylinder 1


Cylinder 2


Cylinder 3


Cylinder 4


Cyliner 4 close-up, worst one.

 

contact DonF here in ht and see what he says

 

seems like a pretty easy fix at a good machine shop. I used to work at a machine shop and the owner used to fix heads way worse than that. Good luck.

 

i agree it is probably do-able but the question is it worth it

edit- I dont understand how it dropped #1 but #4 is jacked up

 

The repair shouldn't be too difficult and any damaged areas can be built up with welding. The valve seats should then be replaced for safetys sake.

 

thats an easy fix. headgames can fix that.

that's cause the chambers are open at the same time so if there are bits of the valve(s) bouncing around they will almost always end up messing up another cylinder. Same thing happened to me when I dropped a valve in my last head.

And yeah they will just replace the valves that were damaged, replace the valve seats, and with the machine work on the quench areas, the combustion chambers might have slightly different volumes, so a good machinist will compensate and try to even out all chambers depending on how deep the damage is. Or like someone else said they can always weld onto it.

 

i still dont see it...the two cylinders are on opposite sides of the motor there only way in is the intake port or exhaust port right? just dont see how a bit of valve could travel that far .. i mean obviously it happend but i cant fathom it

 

REAL easy to fix!

It wasn't a bit of the valve, it was the keeper. The valve is all intact still, just a little bent
