I am near Guadalajara, Mexico and I am seeing some white smoke on idle. I had the injectors 11,000 miles and less than a year ago near San Diego. Thye also put in a FASS lift pump & dual filters.

I have emailed them to see if they will giv eme any sort of warrnty if it is injectors agona. However the problem is where i am. They do not sell diesel pickups in Mexico and find somebody who cna do injectors on a LB7 may be really tough. I also have to have this vehicle out of Mexico by July when the permit expires and I cannot being another truck in until I take this one out. To complicate matters I am towing a Travel Trailer and have a dog and I am escorting an RV caravan. I do have a 2 week window in Guadalajara if I can find a place that works on them. I have used optilube XPD additive every fill up

I have to fly to phoenix for a few days later this month and I have ordered a bottle TPPF injector cleaner in the hopes that may work. In the interim I added a bottle of some diesel treatment (for water & injectors I found at autozone, can't remeber name it began with an R and had 2 chemicals in it that mixed when I poured it.

So assuming Ihave to get this into the US, here is my question.

Can I drive it and simply drain the oil, & refill every 500 miles or so or when I start seeing a lot of white smoke? I gather the danger is too much diesel fuel in the oil pan.

Ok, so you have smoke at idle, white smoke can be a dirty injector causing a bad mist along with other things, not oil...oil will be a blueish tint smoke....I would have almost zero concern driving the truck if it was just smoking...I would worry if your fuel was leaking in oil...the only way to tell is with out a lot of work is:
1. watch your oil level (it will rise)
2. watch your oil psi (it will drop)

injectors are easy there a lot of diy on here...buy a 36 pack a hold up a sign...they will come and fix it in record time...

I posted this in the wrong section by mistake its an LB7 engine and as you may know its a big job on these. After this is fixed, its truck swap time. I am thinking of going Dodge as I spend 5 months a year in Mexico and they can work on those down there. (or gas) Right now I just spent a day & 1/2 driving to Laredo to get this one fixed. 4 sets of injectors in 115K. First replaced at 60K under warranty, second 40k later at $4500, now this set 12K later. The truck is sending me a message. Fortunately I got a steal on it when i bought it, estate sale, 12K on the clock & I paid 30K for it.

I live in western Canada. Truck is still smoking despite the fact I drove it to Laredo and they replaced one bad injector. I am taking it back to the place in CA who replaced them 10 months ago, they will warranty them. Unless of course its something else. The smoke is greyish if I rev it. We took off the sensor on the air cleaner, somebody had some cleaner for it. No dif. Still no extra volumn in crankcase, and coolant level has not changed. I am now in Manzanillo & headed north with the RV Caravan I am running.

The truck is an early 2004 (loaded) with 115K on the clock, dually with Torklift superhitch, FASS lift pump, supersrpings & torklift camper tiedowns.

How much would you be asking for it with the injectors bad or with them fix? I'm from a town call Arandas about 1.5 hrs south of Guadalajara. But I live in Illinois.

Is your oil diluted?
