Plooms of bluey white smoke

[roylittle0]

Update

Well just been out and removed the fuel filter, it looked ok inside couldn't see any crud at all, emptied out all the derv and cleaned out with a air hose, refitted and still have the same problem, also checked the air filter which is clean and dry

I've ordered two new fuel filters to try just incase the filter is blocked in a place i can't see or reach

Any further advice on cause??

sounds like a knackerd turbo to me

Lets not be like that.!!! i want a cheep option

The problems are the same under full power and also with no load, therefore with and without the turbo assistance, the smoke seems to be dieing down a bit now, im just left with the rough engine between 2000 and 3500rpm

just rember this is a derv and not a petrol

I to have had my surf for 1 year and 3 month and my surf has the some black & white smoke i have had the cylinders psi tested and they are fine and return that the boy who tested said was the best results fron that test for a car of the age that he has tested. My surf is a 92 on a J plate and has only covered 88126 miles. I have had the valves clearance checked and they where ok. A full set of heater plugs fitted and the smoke is still the same. The fuel we burn in our surfs, is classed on the v5 form as heavy oil and after running our surfs. After an oil change, the oil will be back to black and that is life with running a derv. You said that you are running veg oil at 15%. If i was you I would get on the phone to Miliner off road and get the derv pump seal kit. They do it for under a £10 with carage. I was lucky last summer I was running my surf at 27.5 ltrs derv & 27.5 ltrs of veg oil that was a 50/50 mix and the seal at the top of the derv pump gave way. I count my self very lucky as if it had been the seals at the back of the pump it would have been a pump out job, and that looks like being quit a dear job. So if you step up to a 50/50 mix run your mix through a heat exchanger to thin the veg oil derv mix before it rots the seals in your fuel pump. If you don't, hope it is just the seal at the top o the pump that goes, and not the one at the block side of the pump. You have been warned and if your surf is not burning oil, the smoke is just life with a surf! The only other thing to do is block off the gas recycling valve on the right hand side at the fire wall end of your engine bay. There is two trains of thought about this. 1 block 2 Not block. Some say block it, but it does not make a difference, but there are those who know that Surf engines run at very high temperature and this can put extra heat in to a very easily cracked aluminium head. So live with the puffs of smoke or block the dam valve..... may your life with the Surf be long and happy, as repair bills are too dam big

Done the steam test and its not steam,

Told you!

Block off the hose to the EGR valve, or better still, buy an EGR blanking kit in case the valve is stuck open. This may fix the blue smoke.

Filter change is the next thing I'd do, using compressed air to clean a fuel filter is a waste of time. If the filter change doesn't help, get the timing checked. Lean fuelling and duff timing are about the only 2 things that can cause white smoke in a diesel engine.

The turbo could be affected by a lean mixture as the excess air tends to liberate more heat into the exhaust system.

After an oil change, the oil will be back to black and that is life with running a derv.

The emphasis was on the THICK black oil as it had not been changed for a long time and thus requires flushing which is what i intend to do, some people use a engine flush solution that mixes with the oil prior to changing it, i prefer to run a cheaper oil through and let that do the job

You said that you are running veg oil at 15%. If i was you I would get on the phone to Miliner off road and get the derv pump seal kit.

Already got a seal kit

So if you step up to a 50/50 mix run your mix through a heat exchanger to thin the veg oil derv mix before it rots the seals in your fuel pump.

No intention of running 50/50 mix

if your surf is not burning oil, the smoke is just life with a surf!

Have to disagree with you on that one, as this has just started and had no problems before, all surfs seem to smoke on start-up, or steam as it seems to be (condensing water in the exhaust) but tis is not my concern, i have smoke ALL the time, as for burning oil, this would give a different colour Bluey Black smoke, indicating a different problem.

The only other thing to do is block off the gas recycling valve on the right hand side at the fire wall end of your engine bay

Already done, about 3 months ago with no effect to the start-up smoke which i am not concerned about.

good man

i hear that the Vatican is looking for a new chimney..... why don't you rent them your Surf???

Unfortunaterly rental isn't an option, as ill need it to get to work on a daily basis

After cleaning out the filter the smoke eventually stopped, so all i am left with is white smoke on startup (or as i said could be water condensation) and a rough running engine, as you sa it could still be the filter, ill block of the EGR valve this weekend and see what that does, if i have no luck with the new filter then i think its down to the garage to have it set up correctly.
