Injection system problems, I think

[Conex]

Need a little input for my brothers BJ40. He rolled it twice into a river (totally underwater) about a month ago and there begins the problem. He took it to a mechanic to have all the fluid using systems flushed and changed including the fuel system. After this was done, the truck smoked (white) a lot so the mechanic recommended replacing the injector points. They were calibrated and replaced. Now when you start it, you still get LOTS and I mean LOTS of white smoke. Looks like the mosquito truck and now has a really bad knock. When you crack the injector lines with it running all are getting fuel and the knock gets a little less noisy (but not much). I personally think the injectors arent calibrated or not set correctly and it is getting too much fuel, but was looking for some direction if I am way off track.

BTW, the mechanics suck here, every single one of them and if it were my truck I probably would kick this mechanics ass for some of the things that he said he did but didnt. EX: "I flushed the fuel system" ok, so why didnt you even open the fuel filter and pour out the pint of river water that was still in it? Numerous other things....sorry.....short vent over. Pura vida.

Did the engine take water while it was running?

I'd flush the whole system myself - new fuel filter, empty sedimenter etc. If the a****** mechanic is as bad as you say then juts buy some new injectors and install them.

I'd also replace the pump diaphram as it might be shot now.

Its hard to say if it was running when it went in the water, but probably, there was still white goo on the top of the valve cover (another thing the mechanic was supposed to check) nevertheless, the whole truck was totally underwater so water was definately inside. Just am not sure if water shut it off. The oil looks good (no water). We have flushed it again and have been trying to diagnose it by running it off a jug of clean diesel. My brother is trying to located some injectors with a little difficulty finding anything other than points. Thanks for the info.

The white goo on the valve cover doesnt sound good.
Im wondering if your engine tried to compress water and blew a headgasket.
The white smoke your getting could be coolant mixing with the exhaust.

If you were getting too much fuel the smoke would be black.

If the engine got wet there was no need to replace the injectors which shows your mechanics lack of knowledge.
Providing the engine is ok it would have needed nothing more than the oil and fuel drained.

The coolant level hasnt changed. To the very top, same every time. I was thinking the same thing, but the truck isnt losing any water. The smoke is white with some black, I just dont get it unless the thing is just totally contaminated with water still.

Does it have a water sedifier underneath somewhere? Maybe thats full too.

Any bubbles in the radiator while its running?

 

[Conex]

No sedimenter, plus we are running it off of jug of known good fuel. No bubbles either. I agree that its probably burning water, but it makes no sense as to where its coming from. We have eliminated everything except the actual head. He just told me that he is gonna pull the head and see if theres anything going on.

Can you do a compression test 1st?
It may have a bent rod and not getting full compression on one cyl

The white goo could be from a a small amount of water that entered the engine and heat is causing it to accumalate in the valve cover.
Just draining the oil wont get the condensation out.

mmm so sad .. !

The knock that you ear inside of the engine is more loud when you acelerate . ?

I'm not sure abut the head gastket .. but if was stoped by water inside ( hydrolocked ) ouch !

My best bet is water in the tank or diesel filter ( water separator if you have one )

 

[sandcruiser]

Conex: I've got a compression guage. Only problem is that I lost the adapter for a toyota motor... so I've never even used the darn thing. I'm sure we could get something fabbed up to adapt to the Toyota glow plug hole and you are welcome to use it.

[Conex]

Thanks Sandcruiser. I'll pass that on and see if we can come up with something. Its a pretty depressing truck to look at right now and would be good to just get it running right again if its possible.

Tapage- The knock doesnt seem to get any louder or worse when at a higher RPM. But man does it smoke, like a hilarious amount of smoke. Not funny to him though. Hydro lock, although the worst scenario, may be a blessing in disguise as I think it would be cheaper for him to buy another 40 and have this one for parts. BTW, I will be back in Panama this weekend.

Dude .. ! you never call me !

All that I can think out of real damage on internal parts are the smoke comes from a water in diesel and failure in your pump .. inyection point os something like that.

 

[Conex]

The only potential problem is that if when he was airborn, flying upside down into the river the engine could have been at a high RPM when it sucked water. If it was idling when it went in, I dont think the internals would have suffered much. I dont think I mentioned before, the thing idles very high right now and the intake butterfly is not open.

Dude .. ! you never call me !

I never have any time when I am there. Playing "Meet the Parents" this weekend and I (Focker) will probably end up just like the movie. Except there may be machetes and a lot of espanol that I dont understand very well. One of these trips I am going to drive down and spend some time cruising around Panama. Maybe you could show me a few trails close to the city.

yes and no .. in a hi compresion engine you don't really need hi rpm to bend somthing inside ..

I'm still thinking in the pump ..

you make me lol dude . !!!!

you must neeed a tranlator

For sure .. yes !!!!

Happened to me a few months ago. Had water in the diesel tank. Got to he water trap and the car idled rough and eventually stopped. Had to drain the water out of the trap about 10 times. Thought about draining the whole fuel system, but fortunately after using 2 cycle (outboard) oil on my diesel and a water remover additive (of course changed the filter) everything went back to normal.

 

[redstang410]

Hopefully its water in your fuel, but most likely its a bent rod. Just enough to cause poor combustion in one cylinder . This also causes white smoke. If you do a compression check you will figure out if thats your problem or not.
Out board engine oil works wonders when mixed in your tank of fuel. Works great to get moisture out and clean crap out of the inyeccion system. Try a quart with each tankfull of fuel.

a knock sounds like a rod bearing might be on it's way out (or it could be a feul knock, hard to tell from here).
when i hydro'd my PZ a few months back i have blown smoke ever since and badly. i never bothered to check it out since the truck runs fine with tons of power. if you loosen the injector and the knock goes down then i would be ready to replace the rod bearings and maybe even one rod...

too bad you didn't have a video of the crash, it might be cool to watch (since everyone walked away)

BTW, i find it interesting that you run down the mechs in the area but don't bother learning to do the work yourself. me, if i find the "specialist" sucks at something i learn to deal with it myself instead of whining about it...

I do ALL of my own work on my vehicle and if it is a new problem, I try to figure it out myself. That is why I am asking on here. This is my brothers ride (was a daily driver) and he sent it to the mechanic because he had about 60 stitches. 20 were on his right hand and that made turning a wrench impossible.

I am not whining about anything. If a mechanic cant fix or doesnt know how, tell me. Dont lie to me and charge me for what wasnt actually done. This is not the first time, every mechanic I have used here has done something stupid ie: I dropped off my foremans Montero to have a front caliper replaced and the rotors turned. Afterward the brakes acted funny so I took the caliper off. The main pin had been ground off and a galvanized bolt had been welded in as a replacement. I have a client that needed a head gasket only to find out afterward that the gasket was replaced with ONLY RTV, no gasket at all. This kind of s*** happens all the time and dont get me started on electical stuff. There is no recourse here for shoddy work. Other than a good old fashioned country ass kickin.

 

[crushers]

agreed

What are you doing overthere . ?

Hey come to Panamá and contact with some Cruiser fellow here that recoment to you a pretty nice garage with Cruiser experience ..

Sound good aaah !
