So.. it’s pretty much expected you include pictures as a general rule. But.. with a post like this ....!?!?

Absolutely MANDATORY...!

I cried about my terrible "piston slap"

Today, I did my best to not slap my pistons as i placed them in a plastic container that i stole from my wife.

It's like we connected there for a moment.

It's happened to me once with this 2012 last year I did a hard stop and left turn and she bound up on me for a second, only did it that one time that was right around the time I bought the girdle and cracked it open expecting to find some metal bits in there but there was nothing.

My 2003 used to do it often.

Oh and i shook my fist at fedex.
Said my bearings were to be delivered today.

Me knowing fedex, probably not.

Yup, i was right.
Fu fedex

There's nothing to post pictures of yet. All I did was crawl underneath it with a tape measure.
Looking at buying a nice vibrant the band flange and flex pipe. Still shopping for mufflers before I make a purchase... And it'll be a long while before my engines actually making that kind of power anyway.
Poor Whipple kit has just been sitting here collecting dust for months already.
Also need DOD delete which means a new camshaft lifters and lifter trays, and if I'm in that far probably some valve springs.
Going to have to put in some overtime to buy all these fun bits.

my 00 did it sometimes but I beat the hell out of that thing I think I went thru about 4 carriers and finally put a eaton detroit in it and then proceeded to wear the bearings out on that never broke the eaton though.

So my blend door doesn’t want to stay on face vents

A recalibration might work but usually it doesn't, to do that just pull the hvac fuse wait a few seconds and put it back in then just turn the key to run for 10-15 seconds you should hear the doors moving back and forth. or use a tech2 if you have one

I’ll give that a shot. What else would fix it?


I guess blend door actuator replacement. What is the one everyone seems to replace it with?

Pulled my converter today.
6l80 has a snap ring to retain the front pump to converter seal!

so easy, no special tools to replace.
One more reason i love the 6l80.
