detonation sux that rocker bolt must have been loose to break the seal sleeve, then return cause the rest of the damage.

Zach you dont log your motor while its running with hp tuners? id think that would be a gimme for a boosted app?

 

yup i didnt have the truning upgrade so that rocker failed...no skeet i dont log my truck while running..i dont have the software and if i did i wouldnt know lol..thats why i have Allen and them do that part .but i know i should buy it and learn.for now i just went by the a/f ratio and it was perfect.
but yes truck was knocking bad about two weeks ago then it went away...so it was probably running on 6 cylinders lol

 

I wonder how much timing you were pushing

 

Jeez, that sucks. Is this a daily driver?

 

I laughed.. then felt really bad.


That suck man, sorry to see this happen

 

Nope not a daily

 

i have no doubt allen probably has the tune conservative just for that reason, you not having a logger lol!!

doesnt look like a trunion fault nor rocker looks like the bolt backed out then retainer started to spin then finally gave? unless you lost the needle bearings on the left side in pic? hard to see .

regardless it sucks and anything mechanically can fail at any given time !


side note, you cant always depend on your afr, theres alot more to it than that, spark plugs being the best bet, checking them often works wonders! i do it even on my NA setup, this determines the number of plug i need to run along with timing blah blah blah!

why isnt it a daily? its just a stock motor with a turbo? then agian you probably mean you just dont drive it often

 

Sorry man. Nature of the beast I guess. Hopefully you can get that truck back on the road soon. Have you pulled the pan yet?

 

Yes I have pulled the pan and pistons already , found all the lil bearings from the rocker . Reason it's not a daily a1000 and 16 gal fuel cell lol

 

Wow,that sucks glotfix
