D6h series 2

Get ready to do a full inframe on that. When you pull the liners you will probably find block deck wear allowed the liner to drop and then blew the head gasket. In that case the block will need to be cut and shimmed.
How long have you owned this cat?

We have only had for few years maybe put 600hrs on. Long story short we had heating problems in transmission ended up being a sticky brake. That would heat up whole machine. So not sure if previous owner got rid of because of the heating so not sure how hot it got.

It was working awsome till last week was using it. It always ran at 180 then all of a sudden was up to 210.

This thread is a prime example of how a simple problem turns into a full blown nightmare of never ending repair because you always find bigger and bigger issues.

I find a lot of head gasket problems if repaired correctly end up in a full rebuild due to deck wear.
I also see a lot of people saying “ just put a head gasket in and see what happens” . You might get away with that if you don’t put many hours on in a year.
You also have that suspicious liner mark that is something I would want to look at. Pulling a piston and liner at this point is easy but your parts list will grow substantially.

Ya wonder what those lines are? Was pretty Carboned up.can't feel the lines with fingernail

 

[Mobiltech]

Looks like something imbedded in the top of the piston. Probably came in through the intake valve.

My guess would be that piece of metal looking object that's between the piston and the liner right at the bottom of the scratch.
Pull the head gasket off.

Are those rings around the valves indented or just a clean spot from the linners. If indented. Inframe and cut block for shims

No rings that you can feel

Think going to take liners out. Can a guy get these out in the dozer and get back in? Or do you have to pull motor?

 

[Bluox]

Do you have tooling to deal with liners ?
Do it look like you can get pan off?
Are the block pitted where the water grommets go?
Kinda looks like that block has been sleeved already.
You may be ahead to get a reman motor.

[4730]

Yes the block is pitted where water grommets go. No don't have the tools. And yes I think your right it does look like spacers under liner. This thing is testing me for sure. Not sure what a remain engine is worth might be worth it though

 

[4730]

Sorry if boring you guys this project is taking forever! Took out piston that I thought was Leary this what found

 

[4730]

Can't believe it didn't totally pile up

 

[4730]

Does anyone know how to check piston oil cooler jets? Is there a way to see if they spray correct on under piston?
