Block sealer in block

   Cascade dishwasher soap? Probably have to disassemble and have it hot tanked, and I won't swear even that would do it....

   I did tell the customer it would probably have to be sent off and cleaned. Which meant a rebuid. Now I gotta give him an estimate for it. It's a BD336

   Try the dishwasher soap first, if you're going to tear it down anyway, what have you got to lose? Some liner seals? LOL

   Good as advice so far Moonlite. Keep in mind the radiator (and cab heater if it has one) may need to be cleaned at a radiator shop.

   Is the engine still fully-assembled or is it just the block that is still in the machine..? Was it the customer who put the sealer in the system..? If still assembled try the Cascade (any non-foaming dishwasher soap will work TBH) route, but be prepared that it may not give the results you hope for. Sealer is an SOB of a thing to get out. If it's only the block that is still in the machine then my call would be don't waste any more time, pull it, rip the liners out and have it hot-tanked. It'll cost a few gaskets and a set of liner seals at most. As posted above the radiator and heater cores will both need dyno-rodding at a good radiator shop. Again be prepared that if that doesn't work you're in for new cores at the very least.

   It's still fully assembled. One the customers hands put stop leak in it on a job. It was putting oil in the water so they thought block sealer would fix it. Oil cooler was the problem. Replaced it. Had radiator rodded out. Got it all back together and now it gets hot after using it for about 15 minutes under load.

   Try the Cascade then, but don't be surprised if it doesn't work.

   Before doing anything drastic has anyone checked the engine thermostat, the fan belts and water pump ?

    I did not see if you said what engine this was but agree with Tinkerer and Nige. I'd keep flushing with the Cascade or some other soap sold for dishwashers, you do not want soap made for hand-washing dishes as it will foam up way too much and cause more problems. Do this till no more oil or slime is seen in top tank of radiator. I normally would not suggest removing a thermostat but in this case it might help the flow to flush things out, but watch the temperature close. The oil could have damaged seals in the pump or maybe the thermostat.
