My bet is on a crankshaft that moved when the the belt was tensioned and the pistons hit valves.... I would double check the valve timing.

I made sure that didn't happen when i tensioned the belt as i tensioned before tightening camshaft pulley(though i did have the mishap mentioned the other day with belt slipping). last guy that had this motor before me did it the other way around and the cam was slightly off making it run like poop esp at idle though the car was driven about 2000 miles that way then i pulled the motor. It did make this same noise when starting at times before i pulled the motor i assumed it was a lack of fuel.

[soapbox]The crank WILL NOT move when you tighten the tensioner unless you have done the timing belt process wrong. You need to preload the belt by turning the crank CCW a little and then CW back to TDC without passing TDC so that all of the slack of the belt is in the tensioner area. If that is done, then the crank will NOT move when tensioning the belt. If that is not done, then then crank will move and the cam timing will be retarded.[/soapbox]

what andrew just said, is 100% accurate..
there is a right and wrong way to set the belt on these engines..
if you set it wrong, you kill the engine..

oh no I always do the 2 rotations to check it. what I'm think is dude before me may have slighly bent the valves and it still ran wondering if it possible? I thought issue before was fueling but maybe its bent valves causing it to run poorly at idle.

even valves that are out of adjustment will not seal all the way, but still allow it to run..
its completely possible to have a few slightly bent valves, but still run.

Yes.
They will even straighten out a bit over time, but then one or more valves will probably drop a head into the motor.

called up some place called diesel injection services to see if they would test my pump.. i made the mistake of telling them someone opened it up they said they wont touch it now.
called location in another city 350 to bench test...

What the hell? Clearly with all of these pumps being 20+ years old theyve been opened by someone at some point.. Idiots!
