Hello everyone,

I have 2 questions. The first is, am I just missing an option to search existing threads?

Second, I need to replace the head gasket on our Kubota L35. The general question is, Should I be replacing the head bolts as well. I have in the past on standard vehicle engines but I'm curious of most do it on the 3 cylinder diesel engines as well.

Thanks.

Kurt

Welcome fellow L35 owner!

I'm usually using my cellphone and there's a magnifying glass to search in the top bar. Using it has advantages; you can filter by member, etc. But if you need to search on a term with less than 5 characters, I think, it'll tell you too many hits. Then you can use Google, or equal, and search 'xxxx site:www.orangetractortalks.com' where xxxx is your search word.

I don't think anybody replaces head bolts/studs unless there is visible damage; they're not torque to yield. It is important to use an OEM head gasket, not aftermarket.

Did the original head gasket have a know failure or did it overheat?
Over heats are know to crack the heads.

Or is it a general a rebuild?

Like @PoTreeBoy said, no replacement of bolts or studs is needed, and use an OEM head gasket.
Aftermarket head gaskets are almost always problematic for one reason or another.

Thanks for the info,

To the best of my knowledge it is the original gasket. I get home and the backhoe under load was making one hell of a racket (clicking noises)

Shut it down and no radiator fluid in the reservoir, oil dipstick completely covered. I guess I'll know more once I dig into it.
