need advice for top end rebuild
my 5.3 has been making some wicked valvetrain noise for quite a while now. i also notice that over the past year or so, the truck just doesn't seem to have the power that it used to have.
i was thinking about pulling the heads and getting them cleaned up, then go back together with all new parts (lifters, springs, etc.)
am i wrong in thinking that this will make a difference? with 200k on the engine, i think that it is just getting worn out. i use it to tow and do grunt work like that quite often.
2000 ECSB 5.3L with K&N CAI, true duals with flowmaster 40s, and 200k miles!
