So I doubt that there's any way you guys could actually help me with this, but whenever I do something awful to my truck the only place to go is mud. I did something really dumb the other day, and now I'm going through oil about as fast as diesel (literally), and in need of a new turbo (I hope?).

I'm actually embarrassed to even say I did this, but I was really stupid the other day and had someone weld cracks in my turbo-attachment pipe without first removing it. This was a really bad idea... I drove about 200 meters down the road before turning back, removing the turbo, and dumping a handful of metal out of it. Now it's, as mentioned above, blasting oil through the air at a rate just lower than my fuel consumption... I can only assume metal got into and destroyed the seal? Anyway the turbo's toast, so I'm going to have to have someone fit a temporary exhaust system that I can use without it, as I'm in a very remote border region between Brazil and Guyana, in the jungle where everyone who lives here is indigenous (so they say), and won't likely be able to source a replacement turbo. This was REALLY dumb of me.

So on to my next question... how much other damage have I done? Even as I did it I knew it was a dumb idea, but I rationalized it by thinking that the exhaust area gets really hot anyway, and all we were doing was sealing up cracks (it was late in the day and I'd had a few beers). The reason I actually stopped driving was because of massive pressure release from a hose on my intake which had split open, presumably due to the heat from welding so close to it. What else might have suffered a similar fate? I've noticed a new engine 'knock' or 'ticking' sound which sounds to be perfectly in tune with the revs. Until I remove the turbo I wasn't going to rule out it being caused by that, but it sounds to me like it's a valve or something? Don't know how the genius welding decision could have caused messed with the valves... maybe the heat did something to the clearances? Is all that oil going through the engine doing other really bad stuff?


I'm sitting on mud putting off actually dealing with this because I think I'll cry if I actually go outside and open the hood one more time. Anyway, just thought I'd let everyone know how dumb I am.
 
That's not good Josh - I feel for you. Bet the girl firend isn't too happy either. :frown: That always makes things worse than they really are.

Pieces of metal going into your intake can bugger up your engine real quick. You are going to need to pull your intake to check for bits of metal. I would not recommend running the engine until you have figured out how much has been damaged: Valve, Piston, Pre-cup, etc.

Your best bet may be a tow back to somewhere where there is someone who knows how to work on your engine or can get you a replacement engine - should that be required. Good luck.
 
Do you really think a piece of metal could have got through the turbo seals and into the intake? Crap.

I already drove the truck a hundred km or so... I just topped up the oil every once in a while and did a trail repair on the intake hose. If I have caused a serious engine problem we don't have the money to fix it... the truck will either have to be driven into the ground or abandoned :frown:

In regards to towing - theoretically I could have it towed to Venezuela, but other than that there are no cruiser parts or mechanics in Brazil, and going back to the nearest town of any size in Guyana to get cruiser work done is 12 hours driving through some really rough mud track...

Does anyone think there could be engine damage from the welding directly? Like as in heat damage?

Okay, I thought I read the air side (not the exhaust side) had the metal fragments. Engline oil shouldn't do any harm besides cause a lot of smoke. I'd still inspect the intake for metal fragments. Use a lint free cloth to give it a wipe and then check the cloth.

Pull the turbo. You'll need to block your oil line. and do a trail fix for air from your air box and reroute your exhaust. Its a trail fix, so all you really need is to get the exhaust out of the engine compartment and out the side of the rig. Best case would be to hook it to your current exhaust.
 
Ah yeah, that makes me feel better... that's what I was thinking too. We'll see if she makes it to Canada... or at least to a container port.
 
Did you weld on the intake or exhaust side? If it's on the exhaust side you probably didn't do much damage but if it's the intake side....

Make sure you stop by on the way north if you're coming through Guatemala. We'll be here till mid-June when we head north for a couple of months.
 
There are not Diesels in Venezuela .. so not much experience with Diesel engines ..

Are you in the BR132 . ?

Did you already change your motor oil and filter .. ?

Did you check your turbo shaft for play . ?
 
If it's turbo seals and the engine becomes a "run away" (ie: you can't shut it off) make sure you choose a high gear and dump the clutch to stall it out. You don't want the engine to self destruct by running on it's own oil.

Really? I had heard it was sometimes hard to get diesel in venezuela because diesels weren't common, but I didn't know there weren't ANY! Crap... thanks for the tip, that's important.

I played with the turbo by hand when I removed it and it all seemed fine... I guess I just didn't get all the metal out, or it was already too late. I spent a while trying to make sure it was clean. It seemed to be fine visually and spinning it by hand at that time.

What's BR132? If that's an area of Brazil, then not yet... still in Guyana about to cross over.

As for changing the oil.... well it's done that by itself!! :frown:

Good point. So far it doesn't seem to be having any problem turning off... so far so good. And to answer your earlier question yes it was just the exhaust side that was welded to.
 
It sounds like the issue did not start until you welded the turbo, right? From the welding they did, can you see any evidence of welding slag dripping into the turbo (as a source of metal)?

When you say you 'dumped a handful of metal', can you tell if the metal is shavings or chunky? Wondering if the metal from a cast part or not.

If I had to guess, I would say that welding on the turbo pipe heated up the turbo innards and something melted inside causing a part inside the turbo to come lose. That piece was drawn into a cylinder and has damaged a ring.
 
It looked like the metal was from welding slag. The metal I dumped out was chunky and silver... I hope there's nothing inside any of the cylinders, but I guess I won't know until later today when I remove the turbo and attach the exhaust. I would hope that anything that could have fallen towards the engine in the manifold would have been blown outwards and into the turbo.
 
Got my finges crossed Josh. Don't forget to run a cloth through the intake hose. If there was any metal post turbo on the intake, there will be metal filings caught in the film of engine oil you will find on the inside of the intake hose.

BTW, I have a neighbour who blew the oil seal on his turbo (Ford) after just having the Prince G eorge dealership check it out. It was making funny noises which they said were normal. It blew when he got to Penticton. He drove it from Penticton to Abbotsford. It burnt up over 20L of oil to get here. But there was no long term damage besides having to fork out $ for a rebuilt turbo.
 
Well I don't feel as bad about my problem now. Hope the rest of the trip back to B.C isn't as much fun as It has been;) It'll be a hell of a story/truck when it's sitting in your driveway though.
 
Hey guys thanks for the support. Took apart the turbo today and it's official, it's totally destroyed inside. I'll try to remember to post a picture tomorrow. Rather than reworking the exhaust system or welding up a spacer pipe to connect where the turbo went, I went the easier route and just took apart the turbo, removed the turbine, separated the two sides with a metal plate, and put it back in place. The exhaust now goes through the empty turbo housing but the intake does not. The oil line was just blocked off... it comes straight from the engine block not from the output from another device, so I don't think that should be a problem.

The truck is very loud, but seems so far to be running normally without the turbo... it feels so weird to be na again!
 
Yeah well so far so good, we'll see after a few hundred km's.

My dad is going to meet us in Panama soon, so maybe I can convince him to stick one in his luggage... that might go down weird with customs, but if he can find one cheap at a junkyard then that would be a lot cheaper than a new one here. On that note my dad knows nothing about turbos and I have not yet scrounged for used ones... suggestions on a good easy one for him to find are welcome, or if someone's actually seen one around one Vancouver Island that would be a likely candidate that would be even better :).
 
Post the turbo type, flange, and the numbers for air and exhaust side. I can't remember what you went with in Ecuador and I am too lazy to search threads.

X2 ... lets see if I can found something here in Panamá ..

Where are you planning to reach Panamá .:?
