MSD DISTRIBUTOR buzzing

[madmaxx]

Wow, you know your distributors!! I did see the pads and although polished, definelty not worn. I guess the beauty of an MSD is the distirbutor is painfully simple. Shaft, bearing, weights, springs, mag pickup. When try to identify my noise I kinda lost confidence in MSD with all the issues I read about not that I have ever had one that would cause the engine not to run.

In the end it was nothing to worry about, but it seams for every 10 I waste my time hunting down, 1 would have really biten me if I did not catch it early.

Now onto my valve cover gasket leak. I am about to the point of using permatex ultra black on both sides of the gasket and be done with it. Gasagacinch? may be good for intake manifold gaskets but useless for valve cover gaskets.


The other problem I solved this week was with my wife's Envoy. It has been a flawless vehicle for 8 years but lately the engine was vibrating everything including the steering wheel, grill, doors, dashboard contents. It was horrible until the car warmed or I you put it in neutral. I was about to trade it in after reading all the nightmare stories on trailvoy forum about the $1,000s of dollars people spent trying to address the same issue and never solved it. I finally stumbled across 1 post, incredibly enough it turned out to be the motor mounts. I replaced them and the car is like new, it is so smooth. I also determined the mounts had to be GM aftermarket dont work. The mounts are fluid filled and apparently over time the bladder looses it elasticy and they become "solid". So digest that, gm doesnt make a smooth engine they just compensate with motor mounts!!!
