Massey Ferguson 65 Industrial engine issue

Good evening everyone,
I recently purchased a 1963 MF 65 industrial loader tractor with the Perkins 4-203 diesel engine. The older gentleman who sold it to me was in poor health and could no longer get down to work on it. He was told it needed a new water pump and fuel filters by the previous owner. He had it delivered to his house on a rollback and installed a new water pump and hoses. He routed the lower hose wrong and the fan belt wore a hole in it and he took it back off. I started it and drove it onto and off the trailer full of oil but without water. I didn’t run it for more than 2 minutes each time with a 3 hour haul in between. When it was idling, it sounded like either a rod was knocking or an injector was hammering, however when I revved it up the noise quit. It was blowing bluish-white smoke the entire time. I just installed the new lower hose this evening and when I started filling the radiator, water started coming out of the exhaust. I pulled the dipstick and the oil is not over full or milky, granted I didn’t attempt to start it. I’m guessing either a bad head gasket, cracked head, cracked block, or bad piston sleeve. It will be a couple weeks before I can drop the loader and pull it into my shop and tear into it to see. I was wondering if any of y’all had any insight as to the most likely issue. Is there any possibility that he installed the water pump wrong or left out a gasket or something that would allow water to flow directly from the water pump into the exhaust? I will greatly appreciate any information.
Thank you.

A cylinder head with a chunk out of the side of the exhaust port into the water jacket is possible. If the flow was dramatic, the head gasket is less likely because it would flow less. If it was a real bargain, I would eat the cost. If it was clearly stated that the Pump was the issue, I would seek a bit of reimbursement as it was not as advertized. jim

I don't know about Perkins but many motors have holes in the front of the head where the water pump mounts that are not supposed to go through but if someone winds an over length bolt in with a long handled wrench the bottom of the hole can be pushed in. These same holes are also subject to having the threads deteriorated and the hole becoming oversized. It is only a remote possibility, but if it is the problem it is easily repaired.

Is the engine an A4-203 indirect injection (injectors vertical) or the AD4-203 direct injection (injectors at an angle)? The A4 engine was notorious for cracked heads.

A 63 should be a AD4 both mine are, but you never know 1963 was awhile ago. They are dry sleeve so probably not a sleeve. Not knowing the history and with the water pump issue it may have been run hot. Let us know what you find.

I appreciate the information. I’m not very familiar with the Perkins diesels, but I have worked on the Continental gas in our MF 2135. I’m not sure if the engine is direct or indirect injection. I haven’t pulled the fuel tank out to get a better look. With the loader in the way, I can just barely see the lines going to the injectors. Good to know that it’s not a wet sleeve setup. The flow out the exhaust was fast, and strong. So looks like the gasket isn’t the issue. The gentleman who sold it told me he had put the new water pump in and had to take it back out and reinstall it because he left out a plate that went behind it the first time. Maybe if I’m lucky, without the plate the bolts pushed through the block when he cranked them down tight. When I get a chance to tear into it, I’ll let you know what I find. I’ve got about 100 acres of hay to bale before I’ll be able to work on it more. Thank you again.
