Question about 1996 Chevrolet Tahoe
I replaced my 5.7 liter engine with one i bought from a friend his truck caught fire and the intake and distributor and wires were burned so i replaced them with parts off my trucks engine(same) well when i was installing the distributor and lining the timing mark the the v-groove mark i noticed the crank was hard to turn so i used a pipe and breaker bar and turn it ,but it would only turn about 45 degrees clockwise and the about 45 degrees counter clockwise after diong this about 5-6 times each way it started to make a complete 360 degree turn the i noticed rust color water coming out of a few cylinders, after a few more turns it was fine so i installed the engine in the truck and when i tryed to start the engine it would turn over but not fire up , so i figured the timing was off from replacing the distributor so i waited until the next day to continue and to my suprise the engine wont turn over , so i tryed to turn the crank with a breaker bar and this time it wont move either way , do you have any cllue of what is going on?? also could the water have gotten into the engine when the fire was put out
You are going to have to pull the cylinder heads off and check this water problem out.

The engine sounds like it's seized. Because there was water in the engine it most likely has rusted the cyclinder walls. Now you still may get it to work. Drain the oil from the engine, pull all spark plugs and put automatic tranny fluid in each of the cyclinders (try to get enough in to cover the piston) this will seep down to the rings and loosen any rust holding the piston. Wait a couple of days, after about 8 hours try to hand crank the engine again like you did before ( leave the plugs out). When you can turn if somewhat freely try to turn it over with the starter (plugs still out) now this will make a mess because oil will shoot out plug hole but you'll have saved the engine. When it cranks like normal fill oil, clean the engine compartment lol. and put plugs in. on first start there will be lots of blue smoke because of the oil in the cyclinders but this will burn off in time. Good luck.
