I apologize. Won't happen again. I must have mixed-up posts- thought there was talk of white smoke, liners eaten and Ph testing.

Best of luck to your issues

Everybody's right. The thread should stay on topic, but the OP should be open to discussion that could affect his engine. It's a short thread so there isn't that much information out here yet.

OP, people are going to ask questions to understand your situation. We realize you'd like a direct answer to your problem. It's not that simple or you'd have fixed it yourself. Just relax and an answer will work itself out within a few days. Someone will likely recognize your specific problem and be able to tell you how to fix it. Until then people need to know specifics about your engine. That's the way this works.

I agree with Cadillackid what the diesel Kleen drive it hard you might be might want to put some injector cleaner but that may be redundant with the diesel Kleen. I do like the diesel additive 9 1 1 it disperses any water that might have accumulated in the fuel

Here is an update but not good. I was running the bus to see if the white smoke would just clear off, and then noticed it had lots of blowby which it never had before. I checked the oil and it had lots of water in it plus was way over full. Then I checked the coolant and added well over a gallon. I assume the cylinder liners are the issue... I need to pull the pan and pressure test to see if they are leaking but I will have to find a pressure tester that will fit this rad cap style.

I got the harbor freight automotive kit and used one of the generic ones in there without issue to find my leaking liner.

siure sounds like the liner seals... someone may have gotten it hot.. good thing is you can rebuild that in the bus.. the heaviest part will be getting the head off..

theres more than one youtube video of how to fab up a homemade tool to extract the liners...

you found this early on so you likely have no damage to your crank, so you can just replace the bearings and do an in-frame.. you'll have a fresh motor ready to travel!

THat's what we were getting at when you shunned our ideas and tried to dictate the conversation.

This is a public forum. You're eating your words. you were rude when we suggested that it could be coolant making the white smoke. You didn't wanna hear it. You go away.

no- I'm only pointing out why you should hear anyones ideas who offers them when you're asking us for advice.
You insisted it wasn't coolant, and you were rude when folks suggested otherwise.

Sure seems like you were shunning an idea right there.

I'd already decided I was never going to help you with anything, but I'll offer this bit of advice. Check the attitude, or some of the forum's members that're a little more tolerant than I am might start ignoring your questions too.

Brad_SwiftFur · 06-12-2017, 01:31 AM

To OP:

Seems to me some of "The Regulars" here were offering sound advice. You're working on a nearly 20-year-old vehicle, on which you may or may not have the service history, in which the coolant may or may not have ever been flushed. The DT466 engine, as good as it is, does have its shortcomings, especially when it comes to coolant and corrosion inside the engine. If the school district neglected to keep the coolant up to spec, it could very well have begun to corrode inside the engine, and indeed be causing the white smoke. So, yes, checking the coolant would indeed be a fair suggestion ... followed up by making sure it's not getting into the oil (which happens when the cylinder liner seals fail, either due to overheating, corrosion pitting, or a combination of the two.)

Best advise yet!

AaronTSchultz · 07-11-2020, 03:01 PM

I was hoping one of you could offer insight. I have a dt466e 1999 that just developed white smoke out of the breather valve and also out of the dipstick tube when unscrewed. The dipstick tube smoke has kind of a train puffing to it when blowing out.

My questions are this.

since I haven't really noticed a decrease in power and it's not eating oil can I continue to use it as is or will it create a more expensive fix later

Second is there a possibility it's anything other than worn cylinder rings or a cracked piston?

There is no white smoke coming out of the exhaust.

Thanks.

Also there was red coolant in it when I got it from the school district. So I had to refill it and I used the red prediluted 50/50 high mileage. but after calling the international dealer they said it was supposed to be the green stuff. Would this cause blow by?

definite early signs of a head gasket or head?
but at some point the expensive fix will have to be done.
currently doing an in frame rebuild on a 1990 thunderbird supercoupe for the last few weekends.
long story short you can run it for awhile but its something to budget for.
dont use any of the snake oil fix stuff that is sold it cost more in the end
from a mechanics stand point
i dont mechanic for a living but have been fixing things since the early 80,s
wish you luck

exhaust gas in coolant is a real thing or have your coolant tested.
blackstone labs will send you sample bottles and are easy to work with

AaronTSchultz · 07-11-2020, 05:46 PM

If it were a head gasket or head, wouldn't I see the smoke out the exhaust and not limited to coming from the crankcase.?

We did budget for the repair, my question I guess would be is there any difference doing it now, or waiting until it's a bit worse? We have a possible couple hundred miles trip coming up soon into the mountains of Colorado a bit.

cadillackid · 07-12-2020, 05:29 AM

The last thing I’d want to do is take an engine that is ailing into the Rockies .. without doing more diagnostics it’s hard to tell what’s wrong. Add another couple grand to the repair if you breakdown and need a tow for 50 miles or more.. overheat it and crack the head and need a new one.

I’d want to pressure test the cooling system, blackstone some used oil, and take a compression test.. if it’s just lots of blowby because it’s tired then you take it easy and likely be fine.

If it’s losing compression or mixing coolant and oil or dumping fuel in the oil then I’d fix it before the trip or not take the trip.
