Pulled my head at 222,000 miles...

[rc51kid]

I pulled the cylinder head to day to do a head rebuild due to oil usage and other "PM" type issues. i also developed a leak on the EGR tube so it was easier to address that with the head out. From what i know it was original HG. I am the third owner, probably reasonably well taken care of before me. But i doubt it was "babied" or maintained like a "IH8MUD truck".

The motor looks really messy because i have not cleaned the old head gasket off or anything. The "rust" on the block in the picture is just stain form being out in Moab. It is actually pretty clean. But i would really like to hear what you guys think the light white flaky material on the pistons is. It is actually very light and just a little of it.

You think this might leak a little?


I have some oil smeared in the cylinders to prevent rust. That makes is a little hard to see. But cylinders are full of factor crosshatch hone marks at 222,000 miles! The bore looks great! No indication i am seeing of bad HG. There is some white flaky stuff on the pistons and exhaust valves. I have read this is oil being burned which would make sense from the leaky valve stem seals. What do you think? I am impressed with how good the cylinders looked for 22 years old.

Does it looks like the egr tube could be removed and capped or replace without removing the head?

In hind sight i think if you unbolted the intake manifold and pulled it torwards the driver side wheel a few inches you could reach down and get it off, maybe.

How does that happen? it almost looks like it had a grinder taken to it.

You mean the EGT tube? It is a crack that has flexed open during me removing it. No "grinder".

Ouch

My pipe still looked brand new at 405,xxx miles when I pulled it a few weeks back

In fact, I used the pipe as a grab handle for removing and installing the head

That being said, mine was smoking after long idle periods and consuming a bit of oil

With new seals and guides, she's smoke free

How much oil did it use? And do you normally fill up at a particular brand gas station?

 

[rc51kid]

it was using about 1 quart every 700 miles but ran very well up until the last week or so when i noticed the EGR noise. I didn't use any particular brand of fuel.

The cylinders look real clean to me. As long as the block is clean, rebuild the head, throw on a new HG and you are good for another 200.
