Head gasket question

['94IDITurbo7.3]

yeah Cody, same pics as FB.

Tim, i payed $55 and some change for the same filter head that you got. filter was like $15.

when i pulled the pass head the gasket came with it kind of. it got mangles so no real analysis of that one. the drivers side gasket stuck to the head when i pulled the head, but honestly it looked pretty good. but other than a really obvious blowout, i am not totally sure what would cause issue.

my heads are questionable as well. at least two of th pre-cups on the pass head are cracked good. they are ALMOST to the fire ring.

Hmmm, makes me wonder, did anything come of the hypermax head gasket set?

went to hardware store today to get the fittings needed for my coolant filter. left empty handed. holy crap that stuff is expensive. it is gonna almost be as much as the filter head itself.

also dropped my heads off at machine shop.

got the new up-pipe on the turbo after i did a little "gasket matching". oil cooler came off after i remembered that i still had to do that . just need to clean the block off and some other stuff, make up my return lines, and wait for heads.

well that sucks!


I went to turn up the fuel on my IP today and it will NOT turn to increase the fuel. it will decrease the fuel, then turn a little to up the fuel and then bam it stops. so i took that as it bottomed out and backed it off 1 flat, which is where it was to begin with.

so it looks like my EGT's will be a nice, cool 800 max. with my leaking up-pipe i would have to work the truck to hit 800. when i had the pipe somewhat sealed it was about 700 max.

this a diesel care IP btw. this kinda sucks but at the same time, i'm just glad it works fine.

Congrats are you 100% certain you didn't cut any of the O-rings?

Yeah, Eric; I couldn't make any sense of the darn rings my first (and only) time. Was convinced that I'd gotten the wrong rings; they seemed way to huge to fit.

Once I was starting to damage the end caps, I realized it was time to drop the unit off at my friendly fleet mechanic.

heads are done. guess everything was fine on them. going to pick them up tomorrow.

they did more than just checking the heads out though.

I dont think I would back it out a full flat, just enough that it isnt bottomed. I wonder what is wrong with that pump, you should be able to get much more egt and boost with the pump almost bottomed out.

Got a valve spring compressor? I'd recommend pulling the valves and checking things out before installation. I learned the hard way that what a machine shop says they do to IDI heads and what they really do can be two completely different things. When I got my heads back from the 1st machine shop, I wanted to make sure they were ready 1st. So, I pulled the valves to make sure the machine shop did take the heads down and inspect the valves, seats, and guides like they said they did. THEY DID NOT!!!

So that means the heads needed more work. The old guides needed to be machined and new guides pressed in.

Anyway, the guides are all worn with about 8-10 thousands of side play with the valves in the guides. That's too much. The intake valves are coaked from oil leaking all over them for who knows how long.

Heath, no i don't have the valve spring compressor. i can see "lube" on the valve stems where i presume would be valve guides. the paperwork does say valve job. i do understand what you mean though. the guy i used comes HIGHLY recomened by two different people that i trust.
