i got this motor for a steal, it starts right up and pulls hard, problem is sketchy patch job on front of the block and water keeps getting into the oil. i plan to repair it, first step well be getting what ever the hell they patched it with out to see clearly whats exactly going on. the plan is machine a piece of aluminum to fit what ever holes we find and carefully weld them in. my dad will be helping me with this, with out his help, me fixing this wouldnt be posible

Wow. Well good luck. Can't say I've ever seen blocks with Windows in them repaired. Let us know how it turns out.

blocks cracked at the bottom where the sleeve seats, use moroso ceramic engine sealant in water system it may save it but if not its time to find a new block.

lol, nice. I have seen a few windowed blocks repaired and work well. THEY WERE ALL ALUMINUM, so i think you have a good chance if you get it to a competent machinist welder!

I cracked my block about a year ago when torquing the head with a torque wrench that was off by about 40% in the bad direction lol. after finding the leak (external coolant leak), and the crack, I cleaned it up and put quiksteel for aluminum on it. Retorqued the head with a good wrench, and it held great without leaking a drop for about 6 months. Now it's leaking again. I plan to just weld it up really quick with a tig, when I get a round tuit.

the correct way of course is to weld it. but just know that if you don't drain the cooling system you'll want to put a light vacuum to the coolant system right before cleaning it off and keep it under mild vacuum while welding so coolant doesn't seep into the weld pool. Also, you need to be really fast with the welding, and may need to do a couple tiny spots at a time with cooldown time in between to prevent warping the block. I think it'd also be best to do it with a hot engine if possible to prevent warping as much as possible too.

considering you have an internal leak of coolant getting into the oil, I say good luck to you sir, and expect to need to buy a new block.

I always did want to get this tool. I have heard the round tuit can do just about anything you need it to.

lol, agreed. I hear they're pretty rare and hard to find at times though. And that women seem to think they're abundant everywhere at any given time

i also bet u have another issue besides that patch.

Oil in the water on a sleeved block could be from less than perfect machine work on the sleeves. I don't see how that hole in the coolant part of the back would allow oil to mix with the coolant...
