I have recently had my 1998 Z71 rebuilt tranny put in. The problem I am having is within 60 miles I was driving and the oil pressure gauge reads nothing and the truck slowly dies off. No noise, nothing, but loss of power steering etc.... Headlights stay on and all the electrical works fine. My question is I checked the oil, and it is def sludgy to the point that it hangs atleast 1" off the dipstick before rolling off. Another thing is I have tried to turn the crank, no luck. Also tried to turn the flywheel no luck. Is this motor locked up to the point of no return, and I might as well buy another motor or anyone have any ideas to this solution and also answers?

 

Definately sounds bad.

 

Sounds like a serious problem. If you get it unseized Try some marvel mystry oil(no joke) and an oil change. The marvel will break up the sludge. Drive for 500 miles than change oil again. Problem is this could cause other wear problems to rear their ugly heads such as worn bearings. Worth a try before rebuild.

 

sounds like your head gasket may have gone.. pull the spark plugs, disable your ignition and then crank the engine (if it doesnt crank at all)....it may be "hydro-locked"...oil or Antifreeze may have leaked past the gasket, causing the engine to not turn because liquid(not like a gas/air mixture) does not compress....if oil or antifreeze comes jetting out of your spark-plug holes when you crank it with the plugs out, you need a head gasket. Also, check the antifreeze for oil.....maybe this will help.

 

ok thanks. Whats the best site to buy these parts off of? Like the Head Gasket etc....

 

man how long has it been since you changed your oil. its obviously been way too long.
