    Cool 88 eldo 4.5, changed the intake gasket yesterday!!

    Just wanted to let people know i changed my intake manifold gasket yesterday, yes, it was fun. If anyone has any questions on the procedure, maybe I can be of some help, as a note, the single hardest thin i had to do was remove the danr distributor hold down nut...could they make it any harder to get to?

    Actually, they COULD have made it harder to get to If the gov't/EPA had had their way the distributor would have been welded into the block to prevent tampering. No joke!

    What were the symptom that led to the gasket replacement and did you use the factory or aftermarket gasket??

    hi! well, i used an aftermarket gasket, so far its done the trick, the reason for the replacement was the fact coolant was pouring out in between the the (head-block-manifold) corner in the rear of the engine. the job was pretty involved as far as time wise. the only trouble i had was when i removed one of the rocker arm piviots, i apparently loosened it improperly and it broke, but the dealer had them in stock, it was like 7 bucks thankfully

    When you remove/install the rocker arms on the 4.1, 4.5 or 4.9 remove the ENTIRE ROCKER ARM SUPPORT BAR ASSEMBLY at one time. DO NOT remove the individual pivots. Take the 5 large nuts off the stud headed head bolts (and the four small bolts on the projections from the bar) that hold the aluminum rocker arm support bar down and just remove the entire bar, rocker arms, etc. at one time. Removing the individual pivot bolts will strip the bolt holes and/or break the pivots. The system is designed to be removed/installed as one assembly by turning the 5 large hold down nuts in sequence.
