OK, I recently purchased a 1992 w/ 7.3 IDI, and the owner before me pulled the wool over my eyes, they had stoped the engine full of Block Sealer/Stop Leak, then drained it and sold it to me. But I take responsibility for not seeing it. I ran it 5k miles changed the oil and in 100 more miles it was HydroLocking. We took the glow plugs out and turned the motor over and water came like a rocket out of No.4 Cylinder. We tore the top end down and had the head for the side Hydrolocking MagnaFluxed and Milled .004, put new gaskets on everything too Service manual specs., went 300 mile about one week and it was HydroLocking again. Took all glow plugs out water on No.4 Cylinder. Couldnt work on it that day but a couple days later we took it apart and had water on all even cylinders , 5 and 7. Sent both heads off, MagnaFluxed and Pressure Tested, no cracks however both were warped and needed to be milled .003. I have been around IH diesels 6.9 and 7.3's since I was born and this is the first time we have ever had this trouble, all the rest have been tough. This one is, plenty of power and it sounds great, and a friend of the family worked for the local IH Heavy Truck & Construction for 20 years and says that this engine runs like a champ, even when it is dumping water on a cylinder/cylinders, he has been assisting me from the beginning. We are now pulling the engine to have it sent for cleaning and pressure testing. And if need be bored and sleeved, then rebuilt. Unless purchasing a new engine becomes a cheaper opition.
I have one question... how did water move from No.4 Cylinder to the rest w/o running it for two days? We have a few ideas but are looking for any others.
