Timing????

[KAIMIKAZEE]

just today my truck started to "blow-by??" white smoke started to come out of the engine breather tube along with engine oil....the stacks would spool out white smoke if i would decelerate and then accelerate...

had an inframe overhaul in march of '06.

could it be the timing from the timing gears jumping out of place???

when going up hill with a load the truck would have a knocking and ping noise with it, along with white smoke from the stacks...but most of the smoke would come out of the engine breather hose...

i didn't recognize the problem until a driver cb me that i had smoke coming out from my tanks which ofcourse was my breather hose...

anybody had the same symptoms??

almost forgot my engine's a cat 3406e...

Doesn't sound good.

Without looking at it, I'd be thinking blown injector tip. Are you dumping fuel in the oil???

i saw a truck pulling a hill blowing white smoke but somebody said that was the turbo gone bad.

i thought white smoke was a blown head gasket, coolant getting into the combustion chambers.

black smoke is the turbo going bad, but my manifold gauge is still boosting.

i have a feeling it might be internal, piston rings, etc.

more inputs will be helpful...

i've taken it to the shop that overhauled my engine, still got 3 mos. and 20k miles to go before warranty's over...lucky me so far...

could be I was just going off what I was told by another driver. One of these days I am just going to take a week off and hang out with a diesel mechanic in the shop and try to learn as much as possible

tell me about it...by the time i'm finished fixing my truck i'll might as "be" a diesel mechanic....

I know you are having fun doing that but I guess it will be worth it and you will know how everything is put together. i hope somebody post the actual cause of this would like to hear what the problem is

[mrpersons]

Pretty tuff to tell what it is without being right there with the info you gave us.

If this "white smoke" is coming from the breather pipe in amounts to disturb drivers behind you, I would suspect a blown piston. (which may have been caused by a injector tip blown off)

You need to get into a shop ASAP.

Let us know what you find out.

yeah the smoke is pretty bad when i let go of the fuel petal...

i only drove it for about an hour and a half to the shop after the smoke started to come out...

i'm suspecting it is something with the piston areas...

will keep you guys posted when the shop gets back to me....

[KAIMIKAZEE]

well the mechanic got back to me...

he pulled the manifold off and one of the cylinder thinging is full of oil #3 if i remember correctly...

looks like a blown piston if u ask me...but luckily it's still under warranty...
the guy says cat will pay for what ever the damage is, but what about the labor??he's trying to talk me into paying the labor....or from $55 to $20 some an hour...he'll work with me...

what do you guys think????

it's still in full waranty and i told him that it wasn't like i neglected the motor...if he tries to make me pay for some portion of the labor what would you say if you was in my situation????

[classicxl]

if it is still under warranty why would you have to pay anything

[KAIMIKAZEE]

exactly...but i guess the owner told me that he never ran into this kind of situation before...

but i told him that if he wants money, go after Cat.

i didn't quite understood him either...trying to talk me into giving him a portion for something i didn't do...

[classicxl]

unless they find something that you did deliberately to destroy the engine i wouldn't pay anything

[mrpersons]

Sorry to hear of your troubles.

I went through a similar situation with a DD60 several years ago. Had it inframed by a DD dealer. First run out to the west coast, ran good, but used 18gl of oil in 6k mi!!! Took it back, and they agreed that "might" be a problem. (duh!). Handed me a sheet of paper and asked me to document the milages I actually put the oil in on the next run, which I dutifully did, used 22 gl of oil that time, still ran good.

I finally got them to agree to go in and do it the job over under warranty, but it was 3 weeks before I got it back. I didn't pay them a nickle for that job, but the downtime cost me a fortune.


You should not have to pay for anything. You'll pay enough in downtime.

CAT dealer??

Never got a clear explanation of what went wrong with that rebuild either. It was explained that got some "bad" powerpacks. Personally, I thing someone intalled the oil control rings upsidedown, but they wouldn't admit to it.

Hope it all works out, quickly.

yeah i'm paying enough for downtime already, looks like it's going to be another week....

i have a feeling someone installed something wrong too...

but they won't admit it.....

thanks drivers, i'll keep everyone posted...

careful... it could have been a fuel injector wash the cylinder down...

[KAIMIKAZEE]

well just got back from the shop today....

the head is taken apart...

the #3 cylinder liner is all scored...

anybody with any experience...

the shop is going to have a cat guy come in and check it out...

the motor has had only 70K miles on it after the overhaul....

anyone know why the liner was all scored????

Something broke somewhere and got caught up in the cylinder/piston. It could have been from anywhere the oil or fuel flows. I am not a mechanic. The same thing happened to my F350.

In my case, the entire engine. Remember I am not a mechanic. There was a hole in one of my cylinders. A sleeve would not work nor would honing it or over boring it. In your case any one of those may work. It all depends on how deep the scores are.
