Re: 4.3 problems
Does it make noise only when turning over, or only while the engine is running? Does the pitch of the noise change with a change in RPM, or with the A/C on or off?
As far as shimming out the starter to the correct position, the slip shaft inside the starter should be exactly 1/8" from the flexplate or flywheel teeth. You'll need the correct diameter rod or a 1/8" drill bit to check the position of the starter. A decent Chilton's manual will show you in detail exactly how to inspect the starter position.
The noise you described doesn't sound like a misadjusted starter though. I'm thinking a slipping drive belt or something rubbing against a drive pulley?
