Pls Help.

[Clark's son]

sorry, i had to start a new topic as i found it hard to search from my mobile as I'm outside.

I'm in h'tota in one of my friends L200s.

It has started to spit out some kind of pebles from the exhaust. Is this somthing that came in from the air intake?

Or is it something from the engine. They where covered in engine oil.

I have stoped the vehicle. Is it safe to brinf ot back to colobo.or should i stop it and come back in a bus.

Pls reply soon as i don't won't to damage it as it is not mine.

Ps. It is the turbo indirect injection engine

Any chance it played in the mud recently? River crossing, that sorta thing?

[Supra_Natural]

If there are pebbles coming out of the exhaust and they are covered in engine oil it looks like the motor must have ingested them... that is NOT good! You'll have to get it checked out at a proper workshop.

What if he does a oil/filter change?

What if he does a oil/filter change?

only way for things to get ejected through exhaust is either thing went through the air intake or it was stuck in the exhaust.

oiil filter change would keep pebbles in the crankcase

You know I'm wondering if someone stuck pebbles or whatever in his exhaust as a joke.

I was thinking the same, but the engine oil its mixed in is a mystery..

A friend had this issue on an '89 Pajero, which was also used for off roading quite a bit. They had to swap out the engine in the end. He said it had sand and crud in the sump, which probably explains how engine oil gets mixed in.

thanx a lot guys.

I'll talk to you as i come home.

Is it Ok to drive it back

Soot and water mixed in the exhaust.

are you sure its pebbles? ie- not metalic particles??

forgetting the said particles, i dont see how engine oil could spit out of the exhaust.

if you ingested them via the air intake, (assuming it punched thru the filter element), cylinder scoring could explain the engine oil, but that will give a tell tale sign of smokey exhaust.

was the oil burnt? ur does it look dipped/coated? if so it could be a practical joke like Jdnet said.

Mitsubishi L200? Got a catalytic convertor? If so, liikely that pebbles are bits of the cat's honeycomb interior. Honeycomb can break up if the cat can gets a good bash from a rock from the road or something (or even a decent backfire can do it!). Got a little magnet? Run it over the pebbles. If not magnetic its probably from the cat. Oilly stuff? Maybe soot. Busted cat still allows you to get home OK. Good luck. (or it could just be that joker stuffing things into the pipe)

I wish this was the case,

But i think with time this is the case.

After all I managed to drive it back,

There where no abnormalities, and it took me home no problem.

But 1st thing tomorrow morning I'll have it's oil and filters changed and I'll check it's filters.

Is this L200 one of the newer Warrior models with the DiD engine? If it is it has a Diesel Particulate Filter and could this be the filter executing the cleaning cycle?

I am wondering if the truck is not used much and suddenly you take it out on a long journey where you mat have sustained high speeds with high engine revs, carbon depsits may have been burnt off and ejected.

Like Scootes said, it may have ebven cracked the cat honeycomb and started ejecting it out.

Just a theroy. Becasue I have seen some serious carbon pieces coming out of our fomrer D/Cab after one long trip to Jaffna.

If you notice in some long distance buses when you follow them in the night, small embers ccomes out once in a while, especilly when the driver floors it or down shifts.

THat is carbon pieces comeing out of the chambers.

[Scooter]

The honeycomb screens in a cat can just don't allow things other than gas to get thru. Stay with looking at the exhaust system before getting into out of cycle oil/filter changes.

Diesels dont have a cat, am i wrong?

[terrabytetango]

Diesels dont have a cat, am i wrong?

New ones do.

[Scooter]

Yup, cats are there on most market L200 diesels since 2000 or so. (Proper name is diesel oxidation catalysts and they are little bit different to the ones we use on petrol engines) Flattish buggers on the Mitsi so plenty of surface to get a thump. They fit tight up against underbody at the end of the front pipe. And really, you'd need a RPG to get something through the screens in the cat. Engine debris - if you were unlucky enough to have a motor blow-up - would just jam up against the inlet face of the honeycomb.

Anyway Clark, let us all know what the wash-up is 'cos this is a real unusual and interesting road problem.

[Clark's son]

Actually it was something like JD had said. But not as a joke.

As i was there on a offroading for a construction matter i had backed the vehicle into some sand which was piled.

As it had an aftermarket tip with holes in it the pebbles had trapped in them.

My friend told me he also had the same issue and thanked me for servicing the vehicle and it ended in a laugh.

[Scooter]

Wunderbar! What a lovely story and a nice ending to a big worry
