How do I check my block for cavitation?
I am about to pull my 7.3 that I think blew a HG.
How do I make sure that it has no cavitation?
I am afraid of getting it all put back togather with new parts just to find the block leaks.
If the block is good I am about a week away from my IDI being on the road.

Bill if you are pulling the motor anyway, the best way is to pull the pan and pressurize the cooling system and see where the leak is coming from. I would fill the radiator and pressurize each cylinder through the glow plug holes, before I pulled it the one or ones that overflows the radiator is going to be the cylinders to check.

We'll see.
I don't hope for it to pull like the V10, it has around 100 less HP and 100 less TQ.
If it can get good fuel mileage then I will start using it on trips that I don't need to tow as much and/or run 75 and 80 towing to get there on time.
Joe says the IDI will pull harder than the V10, but I think he's just going crazy from being in California so long.

OK block off the water hose ports and pressurise the cooling system, while the pan is off.
It would be nice to be able to remove the pan while the engine is still mounted, but this is a pain.
If you have water coming out by the piston, you can now turn the motor by hand to get that piston to the top, then pressurise it again if the pressure rolls the piston back down it is usually a head gasket, and usually if it is cavitation it is obvious.

I used to do that when I had to much stuff to haul and not enough time.
Got one 88 in a 70 ticket and that hurt bad enough I try to not do that as much.
