Re: 1994 engine noise
On my 85, about 3 months before the motor went south I experienced a kind of "rattling" sound, it did not go with engine speed but it was kind of an erratic sounding rattle....I was told it was one of the pullys, and sure enough, the big pully on the front of the damper decided to spin right off and cut the lower water hose while i was about 10 miles from home doin about 60. Two of the bolts had broken off inside the damper, the center bolt and washer were missing, and the 3rd bolt could not take the stress, so I lost all belt driven accessories, and all of my coolant....it was not a fun experience. I had to pull the damper, have it drilled, get another pully, which came off a 305 (and I needed to jigrig the belts for that one) and put all the stuff back on, outside in the middle of November in 35 degree weather. So I dont know if you have the same problem or not, but next time you fire your engine, take a look at your crankshaft pully and see if it's not wobblin erradically. If it is, then you know where your problem is. Hope this helps.
