305 knockin Group: alt.trucks.chevy Date: Tue, Feb 17, 2004, 1:15pm (CST+1) From: snipped-for-privacy@sympatico.ca (Jamie) =A0=A0=A0=A0=A0=A0 I have a 82 Chev Scottsdale with a mid to late 80's 305 in it and a
4speed top loader tranny, after it gets up to running temp it starts knockin, sounds like a bearing thats gone, and then goes away after another 15 -20 minutes of running.
Any suggestion?

Jamie, how's that section 8 thing going?
as to yer knock'n noise.... go on outside.....carry a steak knife with you.
Now.....go over to that garden hose you've been meaning to fix the end on..........
Now .....cut about 4 feet off the bad end. (you'll never miss it....remember...you've been meaning to fix it anyway)
Now....get that motor to knocking..... shove one end of the garden hose in yer......
ear......and use the other end to probe around, and try to narrow that knock down to a specific area.
Post yer results, and you'll get some better guess's.
oh yeah.......and fix yer garden hose!
