I am looking at buying a 2001 Tahoe but the owner says that it has a "cold start" and that it taps and makes noise for about 3 minutes when it is started. Another friend told me that this is a typical problem that has to do with the engine rings in V8 models from 01-06 and that the manufacturers did not want to do a recall. Has anyone heard of this or had similar problems?
Do you think it is okay to buy?

 

Sounds like piston slap. Pretty common.

 

yep just piston slap

 

so is it worth buying?

 

yes, im lucky my truck doesnt do it but ALOT of the trucks do it

the piston is rocking back and forth inside the cylinder(block), doesnt hurt anything is the way it was explained to me
