Hi everyone,

Recently taken off the head in my GQ Tb42EFI engine, just want some advice or if anyone has experienced this? i have attached some photos of the entire Head and found the number 10 Valve seat out, which is not like the others they are all flush?

Could it be ceased ? or any recommendations ?

Is there a crack in the head or seat?

She's about to drop the seat.
I had it happen on an sd33 years ago,my seat smashed into pieces and killed the head.a machine shop should be able to fix it

My head was beyond repair so had to get a new one.
Yours doesn't look like it's beyond repair,wont know untill it's been pulled apart and inspected though

Never had a problem with mine again after replacement mate.
Do it properly, not cheaply and it'll be fine
