Head Gasket Valve seat???

[JoshyGQ]

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

[JoshyGQ]

Havent done a complete inspection of it just yet but so far no cracks , will do a clean and check

[JoshyGQ]

Cheers Deano will do a proper inspection and let you know if i have any other questions, how much did it cost to be fixed?

[Deano2506]

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

Hi mate also had the same issue ,
@Deano2506 i also brought a brand new head recently, how is yours after replacing it ? Any suggestions along the way ? About to start putting it all back together soon

[Deano2506]

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