My father in-law has a 1988 4runner with a 3vze, auto tranny, and 100,000 miles. He was going to give it to me, but I'm not sure I want it anymore. The only problem with the truck was a small oil leak, and, being a nice guy, he went to buy some stop leak to try to take care of the leak before he gave it to me.
BUT what he bought was KW Block Seal, and proceeded to pour it in the oil filler hole. He then started the truck and tried to drive it, without much luck obviously. He ran the engine probably 20-30 minutes before he figured out how bad he f'd up. He then changed the oil and filter and ran "motor flush" through it, and then changed the oil and filter again and spark plugs. No dice. It used to run very smoothly, albeit slowly, but now runs like its firing on three cylinders.
I called CRC, the block sealer manufacturer, and told them what happened. The guy said that the block sealer goop was most likely sitting in the bottom of the oil pan and completely blocking the oil pump screen/pickup. He said that if I take off the pan and clean it and the oil pump screen/pickup the engine might come back to life.
My Questions:
1. Is this thing dead? Should I bother taking it?
2. Is this guy just telling me what I want to hear, or does an engine resurrection sound plausible?
3. Whats the easiest way to get the oil pan off?
Thanks for any help, I was really excited to get a free 4runner in good shape, but don't know what to do now.
