Dirty diesel

[SMOKEU]

I've got an old diesel which is burning oil and blowing a fair bit of white smoke, is it worth putting thicker oil in it or adding some stop smoke to the oil? I don't have enough money for a replacement engine at the moment. It's got 15W40 diesel oil in it at the moment.

[blackdog]

i bet its a terrano

set it on fire and buy a starlet with the insurance

Is it a turbo?

[neels]

Is it a turbo? If it is then white smoke sounds like turbo seals rather than the engine, my old saab completely blotted out the road behind it when the turbo went

Burn the fucker -it's fucked.

Or sell it and upgrade to a Harley.

And actually ride the fucker.

Instead of posting shit on KB (You can do THAT when you'r older)

[SMOKEU]

It's not a turbo, it's an RD28. When I open the oil filler cap with the engine running it's got a fair bit of blow by. It still runs mint though, starts from completely cold with about 3 seconds of glow plugging it.

[FJRider]

More like the injectors need cleaned/replaced ... a problem with older diesels ... expensive ...

Ah, the 'other' type of motorcyclist.

The one that wants a Harley.

( As opposed to those that already ride one)

[dino3310]

RD28... wow
i had the LD28 but like a tipical alloy head 6 the back cylinder cooked and scoured but that was black smoke, i would deffinately try some wynns spitfire injector cleaner... if it works then buy a bottle of morleys deisel cleaner and every few tank fulls chuck some in:niceone:

hoping it is just a little bit of shit in the injectors.

I chucked a bit of injector cleaner in but I haven't noticed any difference. It still doesn't stop the oil from getting from the sump into the cylinders.

scummy seems keen for you to get rid of it perhaps he wants a cheap repower for the harley:bleh:

True.

But I DON'T need the smoke.


So get a Harley, ya know ya wanna...

Sorry but only got bad news. The LD28 was a solid and reliable motor and would go forever but the RD28 was alloy head and prone to blowing head gaskets. My old one blew a piston. White smoke indicates a cracked head or blown headgasket and may not immediately result in overheating for a while.

You don't remove the oil-filler cap on an overhead-cam enginge when it's running as you'll splatter oil everywhere...

[SMOKEU]

I might just try a thicker oil and see if that makes any difference. The previous owner said he had the head gasket replaced. I had a proper diesel mechanic have a quick look at the engine and he can't detect any sign of a blown head gasket or cracked head. There is no water in the oil or oil in the water.

I don't care.

Get even a 883 Sporty and you'll be miles ahead.

aw shite i got the LD - RD round the wrong way:facepalm: was a while back...
but yeah the RD alloy head was a bloody nice car all the bells and whistles and comfortable on the long hauls, but the rear cylinder gets scoured easily with over heating, typical six....
is she heating up on the up hill legs bro

Not easy to detect, but any smoke other than black is an issue. Mine started using oil but still ran well and the blown piston was a surprise. As I said, white "smoke" is an indication of a cracked head. My Estima Turbo Diesel suffered that and ran cool and with no power loss. It wasn't until I got to my mate's garage and left it idling for a bit that the white smoke started with that sickly-sweet smell of coolant. Smell the exhaust, and smell the dipstick as the smell of the oil can be a good indicator of what is wrong, too.

I had an '88 Laurel Hardtop. A fantastic cruiser that was a dream to drive! But it blew a piston just after I sold if to a friend of my wife's... Not a good thing to do... :msn-wink:

I don't have a big enough boat to warrant an anchor of that size! I think the head off an 883 will be a big enough anchor for the old dingy.

I haven't taken it on a long enough drive up hill to test it. The diesel mechanic who had a look at it commented on how easily it starts and how good the engine sounds compared to most other RD28s. He revved the engine hard while in neutral and there was no visible smoke coming from the exhaust.

There is visible white smoke coming from the exhaust most of the time while I accelerate at a "normal" pace. The car has been sitting in a paddock for most of this year.

They're nice cars, mine is a '88 pillarless manual one.

That's what I had but an auto. Comfortable cruising at 150km/h, (desert road, 1am, on way to Chch...). We loved it! But very disappointed that despite the previous owner's, (a good friend), fastidious servicing and care, and our same, it still blew the piston and it wasn't a huge mileage on it either.

Due to the time sitting an injector cleaner will take some time, 1000 plus k's at least. BP do an Ultimate diesel fuel with a cleaner additive, use it initially to clean the injectors along with the moreys additive every fill, and then Gull fuel should be used after the white smoke stops. If it stops. Give it a good thrash every now and then.

I now use a nissan wagon with the CD17 that was left to sit and someone had filled with petrol by mistake. Its running condition still varies, some days its strong others it struggles for power. Its slowly coming right after 2 months.

Hope that helps

Burning oil won't make a diesel put out blue or white smoke - it runs on oil and will just burn it as fuel...overfueling will result in black smoke.You will have a hard time finding 20-50 HDEO....if I could find some I'd use it in my airhead.White smoke is cold smoke,or if hot caused by retarded injection timing - have the timing checked with a DTI.The RD28 can crack heads,and you could be confusing white smoke with steam - white smoke smells like kero and will sting your eyes (well,it did with sulphur fuel).

Had an RD28 Laurel for 5 years,apart from an injector pump it was pretty trouble free.Being a 6 cyl they have little torque,so you have to rev the snot out of them,and being a diesel it won't rev anyway.Can't see the point of a small 6 cyl diesel,a 2.8 4 cyl will clean up an RD28 everywhere.

I can sometimes smell smoke in my car which seems to be diesel smoke. I've got an RD28 in my other Laurel but it's done high kms (around 350,000km from memory) and since it's just a parts car I've never started it so I don't have any idea as to the condition of the engine. I was thinking if my 'good' Laurel has a cracked head I could replace the head with the one off my parts car.

It doesn't appear to be leaking oil, so that oil must be going somewhere.

The diesel mechanic recommended that I change the oil after 500km to flush out all the shit that's left behind, then just run it on cheap mineral diesel oil.

[scissorhands]

Diesels just use sump oil as fuel....ever see blue smoke from a diesel? no

I have some commercial fuel treatment stuff I can give you. Its made for MDO and bunker oil boat motors.

How old is the fuel? sounds to me like the fuel itself might be the problem...... especially if the motor has been sitting for a while..........

It does not suprise me that it is burning oil espcially if it has been sitting for a year. If the rings are possibly stuck, try a med-high ash oil as these have strong detergents and should free them up with a bit of use that is.

I brought a landrover and thought it was stuffed because it burned oil, it took about 2 oil changes before it came right, the compression improved and it has stopped burning oil with a bit of use.

The diesel fuel in it is good - it had about a 1/4 of a tank of old diesel so I filled the tank completely with fresh diesel and a bottle of injector cleaner as per the instructions on the injector cleaner bottle.

I note you say it's been sitting in a paddock for most of this year - if it hasn't had antifreeze in it then odds on it's a cracked head...
you don't say if it's losing coolant.

If it's not then check injector timing as has been suggested - I've been told stories of imports with timing way off.

Yup, no antifreeze in it. I'll check if it's loosing coolant.

What I might just do is go to a diesel mechanic and tell them I'll pay them an hours labour if they can diagnose the fault. Since it's just a mechanically injected engine it should be quite simple to diagnose the problem if they know what they're doing.

[scumdog]

They're nice cars, mine is a '88 pillarless manual one.

Faaaark..old mans car to the max~!!!

My old man is eighty-fuckin-six years old and has an '86 Skyline GT-D pillarless, a Jappa-Caddy!!

A freakin' DIESEL labelled as a GT? - it's like saying a Hayabusa 250!!

Or mature boi-racer.

Or a s3nsitiv3 cop......


Mwahahahaha....

Not a lot of choice in ChCh I'm afraid...guy at the Diesel doctor told me my LD28 had broken the cam belt.....pardon ?.....broke cam belt mate.....now tell me the truth please, it has a cam chain mate.....much embarassment.

My LD28 was in a CF Bedford - PC Cresta (you won't know what that was scummy) diff and O/D - 130K cruise with bikes on board.
And the wife still brags about dragging off a Porsche 944.....
I'd still have it but it finished up as a Bedford shaped block of bog.

$3,100 brand new they were, the Viscounts were Pommy import models twin headlights, bucket seats etc..and cost more.

Can't bling you twice in a row! Our Nissan Pulsar is of course chain and at 186k it's still running like new. I reckon cambelts were one of the vehicle industries worst ideas! Cam chains aren't THAT noisy that one needs a belt... Classic_Z had a Toyota Rav4 in that had premature cambelt breaking 30,000k before it was due to be replaced. Of course the previous garage is unknown as all they'd done is write on the paintwork that it was next due at 205k. It is possible they didn't change it at the time and just pretended they did....

LD28 has a camchain,and an injector pump belt.Bit of a trap if the injector pump isn't working but the cam is going around.

My second "car" was a CA Bedford and I also owned a PC Cresta which was a fabulous cruiser! I always want the Viscount, though, and the FD Ventora with the 3.3 and 4sp...

Yeah the CF's could rust faster than an HQ Holden!

My 14 month (in 1973) old 3.3 Victor (4-speed) would out-run anything - including cop-cars. (apparently...:sweatdrop:whistle:)

Ok duly amended - but really they were POS - when i worked at the Farmers who were agents all the staff cars were PC's...the staff took pleasure in breaking them.
And the later ones when they went unitary construction would stretch if you pulled a caravan...no joke the door gaps would open up.
However the diffs drop into CF Bedfords and give a resonable open road ratio.

Or so I've heard... LOL!!! They were as fast or faster than the V8's of the time! A genuine factory hot-rod that had the style the speed and the handling to see off about anything less than an Italian exotic of the era! I'd have one today!

I bet it didn't burn half a litre of oil every 200kms like mine does. If it was just a bit of white smoke without the oil consumption then I wouldn't really be worried.

[LBD]

Stick with 15W40/10W40 Diesel oil...

Is it getting up to operating temp...+_80C? If the engine is running cold you will get white smoke....

Does it go away when de accelerating?

Unburned fuel is seen as white...
