Im replacing my headgasket on my 87 Pickup..i know i let the chain slip down a little when i took the sprocket off the cam, so know for a fact the tensioner has to be reset, but not sure if it completely fell apart or if i could do what one guy did on here with a long wood drill bit and push the tensioner back..i have taken the head all the way off and cleaned the area for the new gasket but i thought for a try, see if i can get the sprocket back on..with some effort and prying the sprocket up with the chain on it, i can get it back on the cam when i dont have the gasket on or bolted down the head.. so how would i know if the timing chain tensioner fell apart?....another question, how would i get the crank bolt loose with an automatic transmission?..i cant think of any ideas on what to try to get that bolt loose..
sorry for the long story..
The crank bolt will come out easily with an impact wrench. If you don't have one, pull the tranny dust cover and put a prybar into the teeth on the flywheel ring gear. Then your best friend can break the bolt loose with a socket and a breaker bar.
