89 b2600i

Been a while since I have posted on here. I picked up an 89 b2600i for dirt cheap. It has a blown head gasket and im in the process of yanking the head. I have no real experience with pulling these jap engines apart. How do I go about freeing up the timing chain to pull the head? Do I have to pull the motor or can this be done with the motor still in the truck? I have the intake and exhaust manifolds off and the radiator out. I dont want to do more work than I need to so any help would be greatly appreciated!

bump?

sorry man i have never had to do a head gasket, however i am interested to know how its done hopfully someone chimes in soon for you!
good luck bro

i highly recommend that you pull the motor to do your work. if not, however, you can take the bolt out of the gear on the and pull it off with your hand. be sure to keep all timing marks in line and do not move them. have it at TDC on the number 1 piston before taking things apart. when you put it back together you will have to push the tensioner in and hold it in place. put the gear in the chain and then put it back onto the shaft. works good with a third hand. be careful not to Fuk up the gasket when putting the head and timing cover back together. hope this helps. if any more info is needed
