My 00 5.3 w/150k does it on the cold start then goes away. It gets annoying sometimes cause ppl think my motor is shot. But I guess it normal and dont affect it. I been considering a turbo kit for mine but wondr if I will hurt something any thoughts fellas.

I got it! Mobil 1 every 3to 4k. Always been there, It use to not be that bad but seems to have gotten a lil louder lately. Tahoe runs smooth and strong without issue.

Hi All
I would try to make sure what is going on Before you change things
Most likely piston slap.
BUT could be many other things.
#1 pull an oil sample send it off to someone like Blackstone Labs
This is very inexpensive to do and will tell if you have any
severe problems Rod or Main bearings Coolant in oil ect.
" If you pre pay for six in advance even less costly '
Sinse i have started doing so I have only been changing my oil twice
a year No mater what the milage
I use only high qualty synthetic oil and good filters Even at that it shows
I am wasting Time a Money changing that often
I Drain my Transmission Pan By the Plug with each oil change also
I use Full synthetic trans fluid "You will only get about 3+ quarts out"
The last analysis showed almost NO WEAR with 149++K miles
I Do a LOT of TOWING Open Car Trailer with a Corvette
I have towed this set up on several long trips through mountain ranges
wit no problems
I have added a LARGE trans cooler 28K lbs. Stacked Plate Type and kept
the factory cooler
These trucks will last a Very Long time with Good mainantance and mods to
help with the week areas
Good Luck
But rember you should try to know were you are going befor you leave
you can plan better
