How do you all get 6.2s to 300K miles

....oh God no.

Guess im going back to driving my clapped out, misfiring 3.4L 01 Impala

hate that thing, lowkey, ill never understand why its misfiring. I replaced the spark plugs, coil pack, spark plug cables, etc. Still does it

A friend over here has some kind of a chevy, sort of a blazer looking thing.
Inline engine, 2005 IIRC.
It had a misfire, chevy dealer worked it over, its fixed, well it was for a phew days then started in again.
He read on some innernet blog where some mechanically inclined guy got his not very old battery checked. Battery was weak. Replaced the battery and misfire left too and never came back.
Bob, my friend got his battery tested, wasnt real bad, he had it changed and same thing, misfire left and it has not had another misfire SES lamp since then:

Does it seem to clear up after about 45 seconds to a minute ?
Possible that the valve stem seals is bad.

Update:

Got everything off, bought a kit that provided a new front seal aswell:
(https://www.oreillyauto.com/detail/...let-k5-blazer?q=timing+cover+gasket+kit&pos=0)

Havent bought a speedi sleeve, i think its included on there though? If not ill definitely get it. So far though we got everything off, all the bolts REEK of burnt oil (cant smell any diesel).

a question though:
What belt is missing? It was always like this but now that the front end is entirely off, may as well actually get it (what type of belt, size, etc)

lastly. I already bought replacement hoses, got the new radiator mounting pads finally installed (old ones were damn near gone) if I should do anything else, please let me know, everything is still off so I can go back in and do it.
