To get the passenger side valve cover off (gaskets leaking) you have to remove the heater hoses. Not bad but they are like pipes from being dry. No big deal just change the hoses. No big deal but the hoses go to the heater core INSIDE the cab. To get the heater box out you have to remove the A/C which is under the dash. The plugs on the pass side will have to have wife get them started as my hands do not fit in there. Corvette yes they are a pain in the ars, but they are not as bad as this. Can't wait till I change the fuel pump and gas tank what exciting things will be revealed there.
