Hey whats up?
i just picked up a 1984 6.9l with 190k on it

it has
banks turbo
injectors been turned up ( to what i have no idea)
it has a boost gauge ( although it really only builds boost when shes winded out)
and a pyro meter ( runs near 5-600 )
6 inch brand new rough country lift
36x12.5x16.5 tires ( where can i get a set of 35-36inch with a 16.5? tires having a hard time finding them online)
4 inch straight banks exhaust


I'm still learning about it and tinkering with it. it runs strong a little white smoke whens shes cold ( why does it smoke? ) once I'm moving down the road and she warmed up it runs awesome.

so i been lurking and reading on the forum about this truck and other standard how to's/fix its.

so i learned what cavitation is
now is there and additive that i can add periodically to the coolant other than just swapping coolant out all the time.

and i been reading about fuel additives
I'm guessing 2 stroke oil is the norm
and other advice?

and does anyone do the sea foam treatment to there trucks?
i was thinking about doing it ( have to go thru the vacuum because i assume you cannot feed it thru a turbo haha )

any problems these trucks have that i should know about?
i plan on running this motor till it dies and by the sound of it and the way it runs probably....somewere near around the year 2090. then ill swap maybe a power stroke or another rebuilt 6.9l


my known problems

truck sways on road when I'm driving on highway I'm 99% i need a sway bar and i cant find one for this truck anyone know ?

the tranny wines when in the higher rpms
the original owner said he swapped the old tranny out because it whined for a newer ( less miles) and it still whined. is this normal?

the driver side floor pan is near shot just going to take that to the body shop

and thats about it other than cab corner with a little rust everything works even the two tanks (miracle i know)

and advice for a 1st time owner?



also i just got the oil changed/fuel filter glow plugs tanny serviced ( have not driving it yet still in shop) and rear diff fluid changed (asked them to look at transfer case). so I'm up to speed except coolant on maintenance stuff i believe?



also i frickin love this truck hahaha

 

Glad to have ya. White smoke is normal on these old diesels...
