The list your book gives you are all things that will cause a knocking noise. Only way to fix is to open her up. If you were having overheating issues before this happened then it could have damaged any of those except pump.

Can lifters be replaced


Oh yea, lifters can be replaced , best if you replace cam an lifters together ! Loud knocking is not usually associated with lifters , they usually make a ticking noise ! Knocking noise is most usually in the bottom of the motor , main or rod bearings . most of the time rod bearings !

350 Chevy knock might be a blown rod or a lifter stuck


Knocks in the engine can be defined by the frequency that it happens . If it is a cam follower it would be a constant knock and there would be more than one as if the cam follower or cam lobes are failing . A heavy knock can be a big end or a main bearing failing. Remove the plug wire and if it is a big end the sound will be a lot less as there is no combustion pressure pushing down on the crank pin. When you have got the rod you think it is then remove the plug as well and there will be virtually no noise when running. If the oil pressure is good at idle then the noise may be a broken ring or cracked piston. All produce a knock in an engine A stuck lifter should be holding open a valve so you will have a miss as well as the knock.

I have a 2003 gmc Sierra half ton 4.8 liter that has a knock that sounds like lifters


There is,If you do the lifter you could be after something else,The noise sounds like a collapsed lifter,A collapse lifter can cause a misfire,The 2003 GMC sierra or I should say the 4.8 engines suffer from a cut O-ring between the oil pump screen and the oil pump causing oil areation,resulting in lifter noise,The noise will be present a cold start and then diminish at warm up.12_3_2012_8_08_44_am.gif

Moter knocks when i first start it then goes away


I had a chevy 2002 avalanche,2004 chevy tahoe both after 20,000 miles developed a mild lifter or slight bearing knock.When I confronted chevy with this problem they stated this was normal for the 5.3 liter v8.Being a mechanic myself didnt think this sounded right.My friend has a 2003 gmc yukon and motor sounded same way.I no longer own my chevy,But my friend still has yukon with 150,000 plus miles and yet it still knocks when you start it.this is just a problem with chevys and other gm products.
