New engine smoking badly ???????????????????
Turbo Mini Forums

Well here goes ive just run the freshly built engine from morspeed ,in consists of A turbo booster head, 1293 block omega pistons all new bearings rings etc, and a rebuilt turbo, one slight problem smokes badly ,I can understand initial start up smoke but ive run it for a while now and does not appear to be clearing but getting worse. The plugs are well oiled too.

any advice would be greatfully welcome cheers Rob

Hi,
I know that freshly rebuilt engines do smoke, but this goes away over time, the oily plugs could suggest the oil seals on the turbo or valves are to blame, has there been any improvement since driving it more?

Cheers, Kav

there has been no improvement and the turbo has had a full rebuild from its turbos the head was straight from morspeed along with the engine

Hi,
Who built the engine?
Any other problems?
What's the timing and mixture set to?
Does it stop smoking if you jack the front up?
Have you tried running it with the plenum intake pipe disconnected?
How are the breathers connected up?
Cheers,
Gavin :)

My Mini build diary

Take the plugs out, clean them up well. Disconnect the turbo outlet pipe leaving plenum to draw in air, and re-try. This'll confirm if it's the turbo or engine.

If it is this bad, you'll find a lot of oil inside the boost pipe.

How many miles have you done in it?

From cold its ok but as soon as its upto temp it starts smoking,i have put it on ramps still smokes ,disconected the turbo out put pipe not a whispa of oil still smokes ?? I put the block to gearbox and head to block Morspeed built the motor i have driven for a mile or two and run for a good few hours??

is it breathing at all?

Doesnt sound good.

Mine smoked a little to start but then cleared up.

Have you had the exhaust elbow off?

Mine smoked like fook once when i had a dodgy oil drain and basically it wasnt burning any oil in the engine, just after it.

Just wondering if the dark plugs are a red herring as mine were dark due to incorrect mixture but didnt cause the smoke.

I have removed the timing chain case with the breather for a non breathing one, to make space for the electric water pump pipes but i have got the breather on ther rocker and clutch housing.

look down the bores, see if there is any scoring of the bores maybe

I'd go with Tom's advice here.

I shall give it a whirl i will get back to u once ive completed some milege cheers for the advice

I really do think that is what it needs, it is also important to do mileage that varys the engine speed and load, sitting on the motorway at a steady 60mph is not really any good, stop start fast speed low speed varied is what it needs. Good luck buddy.

second that tom

it may be too late heed this guys advice

and its dam RIGHT!!!

I have rebuilt several tractor engines with the same problem if they are left to tick over by the operator Usually to keep the cab warm! they start smoking a hard session on the dyno usually breaks the glaze and sorts them out!

Iam having similar problems myself have you fixed it now? iam now thinking that its the oil getting to thin when the engine is up to temperature?
