Changed IM gasket this morning .
The old one didn't look bad,but one of those rectangular windows (I gueess for coolant flow) has a slight damage.
It'* located near cylinder #5 so maybe this explains why I had random misfire on #5.
Went to dealer to get SC gasket--not in stock.
He ordered from some place in Manhattan,I guess not that many of Bonnevilles needed this part here.While out,postman left notice-probably coupler and oil arrived.
Rollingperformance.com sends it from NJ so it'* right across the river.
Hope nosedrive will arrive before noon on Thursday so I can finish it on that day.
Dealer didn't have red gasketmaker either,but I saw same red gasketmaker,just not under GM brand in autoparts store.
The only pain in the neck will be tomorrow to unscrew nut from SC pulley.
It has to be hold somehow,noseshaft is lose.
Don't know,will try.Basically I do everything "on my knee".
Will post new updates upon availability.
