Thanks for the input. I forgot to mention that is car is automatic. Does that make pulling the engine harder? I also have a passport with the same tick, tick, tick, tick. It drive me nuts. I hear that for that engine I need to replace the rocker arm shafts. Anyway thanks for the input. I hope you see this posting as I am new to this message board thing and not sure how to reply.

My 85 gl two wheel drive ea82 engine (139000 miles) has gotten a real bad tick. I read about changing the mickey mouse gasket on the oil pump and some o rings under the cam towers? and also the crank shaft seal. Does anyone know if this can be done with the engine still in the car? Also my timing belt is due to be changed. Should I replace the tensioner and the water pump while I'm in there? Does driving with this tick hurt anything?
