HazT, I did not have problems with butterfly valves. I stupidly had the 2nd version of the crank bolt in and it broke off flush with the timing sprocket. The bolt had to be cut out after drilling a hole in the middle of it since no left handed drill bits and extractors worked. I put in a Time-Sert and all was well until a nasty little coolant leak recently developed at the water pump.

I like Justice's solution. I guess I missed that explanation before...completely.

Lloyd, turn a wrench once in a while, man! Not all rebuilds and plenums are the same. It can be done.
