International 650 diesel

[1974vette]

I’m working on a 650 I bought a while back knowing it had head issues with compression getting into the radiator. Head was redone and was not cracked. Head gasket was blown out around all 4 sleeves. The tops of the sleeves are pitted pretty bad. Are they usable or will they not seal with the head? What caused the pitting? Running it too long with bad head gasket?

I would not reuse that sleeve. It looks like it has had both water and heat damage as well as some scoring. For me, it would be a bad risk to use it again.

I kinda figured that. That was the worst one but the other 3 are also having same issue so I guess I will suck it up and pull them all. Thank you. Definitely not worth the risk

On those old engines head cracking was only one issue , they were also prone to blocks cracking in the bores . Now i have never been into the D 350's as we never had any of them around this area in a ag tractor . Only place you would find them was in the T D 9 crawlers and again not many of them . Company i worked for way back had a total of 8 , 4 dozers and 4 T D 9 's with a crane boom mounted dead center that we used on water and sewer line work and as a mobile crane for infield service work on the big tonka toys . Since we did not use them much i don't remember a time when we had any of them apart.

When I get the sleeves out I will clean up the bore and check closely for any evidence of a possible crack. This only my second d350 so advice from knowledgeable people is always appreciated.

Head was redone and was not cracked.

Did the shop just magnaflux the head, or did they pressure test it too and make sure there were no leaks?

Have you pulled the sleeves yet? If not, is it possible for you to measure the sleeve protrusion of the other sleeves?

Could you possibly post a picture of the bad head gasket, the head surface, and the block deck?

Are the block deck and head surfaces completely flat (checked with a super-straight straightedge)?

Was there any coolant getting into the oil (or vice versa), or just compression in the radiator?

Would it be possible to magnaflux the block deck and make sure that's not cracked?

Just throwing out ideas.

Now today many shops do not pressure test the OLD way . They use just air pressure and bubbly spray stuff . the OLD WAY was to run HOT water thru till the head was 180-200 Degrees all over then add in 30 psi air , Then ya would find the leak . i went thru this new way on a set of 930 case heads . Now not being a Case guru and working with a machine shop away from home base . tractor was getting compression into the rad . SOOOOO either head gskt . or Crack Took them to that area machine shop and they pressure tested with there new head and block stand found nothing and faced the heads and did the valve while off . Go back down threer days later pick the heads up and go install the heads and go tezst run the tractor in the field and we still have compression in the rad . Pull heads and go back and tell them that one of the heads has a crack . So the place each COLD HEAD back on the stand block off all water passages and apply 20 PSI AIR pressure and spray bottle it , Nothing , I said add HOT WATER and get the head warmed up . I get that takes to long , i told them that driving three hours on a service call one way then drive back and come back down takes longer and i do not like redoing my work . To speed things up we used a propane weed burner with water in the head and a temp gun and now 30 psi air pressure as the head warmed to around 150 OLD Faithful raised it's ugly head and water strated to seep next to a valve seat . So if only 30 psi pressure on water and a 150 degrees of heat think how fast running engine compression and 8-900 degrees temp would react. .

What was your setup to seal the head to test it with water?
