motor noise Posted By: 98ls1 On: 01-04-2008 @ 22:47:34 Reply | Edit I recently started hearing a slight knock on the bottom end of the motor. I thought at first it was on the top end but I pulled the valve covers all rockers looked good checked push rods for straightness there fine I retorqued the rockers to specified torque. I started up the car I hear a noise still I jacked up the car got under the oil pan that is where Iam hearing the noise, I took it to basko engines (I've had a stroker motor built there for my blazer) He said he thinks it is a collapesed skirt of the piston. Any have any idea how long i have on the motor , the car only has 79000 miles on it, It was a retired texas dps car though. -- ima://Documents%20and%20Settings/MOM/My%20Documents/My%20Pictures/Picture%20or%20Video/Picture%20or%20Video%20202.jpg Posted By: BlackScreaminMachine On: 12-14-2006 @ 07:43:06 Reply | Top | Edit WHo knows it could go 1k more or 100k more. But if it blows hope it doesnt send a rod through anything -- 2002 Navy Blue Metallic Trans-Am- Stock as a Rock!

At least then you'll know whats going on and maybe try to salvage some good parts before they unusable like the crank or rods. -- Dan 99 Z28 M6, No Options, Free Ram Air, SS ELiminator, TB Bypass, Holley Power Shot, SLP Air Lid, Vortex Muffler, FTRA, Pro 5.0 w/short stick, Mac Headers w/Carsound Cats, !EGR, NGK TR55 plugs w/ Taylor wires, LS1 Edit Tuning and K&N Breather. 321.69hp, 331.91 tq.  Posted By: 98ls1 On: 12-14-2006 @ 14:54:04 Reply | Top | Edit you have to pull the motor from under the car with the k member suspension and transmission all at once I think i might have a problem doing that in my garage. Any advise on this , or just take it to a performance shop and stoke it w/ forged internals for $5ooo that would be a 383 w afr heads for a stroked 383 and a $1000 for remove and reinatall. -- ima://Documents%20and%20Settings/MOM/My%20Documents/My%20Pictures/Picture%20or%20Video/Picture%20or%20Video%20202.jpg [ Edited on 12/14/2006 @ 15:02:28 ] Posted By: cheddar On: 12-14-2006 @ 16:44:15 Reply | Top | Edit or just take it to a performance shop and stoke it w/ forged internals for $5ooo that would be a 383 w afr heads for a stroked 383 and a $1000 for remove and reinatall.
