after months off the road due to 2 knackered engines bieng sold to me by c**ts finally got in running with reconditioned engine had new be bearings and main all heavy duty new belts, plugs, motorsport leads, std cam thats wat i have recipts for i have done 500 miles to run it in as i was told to but the last 100 it started to smoke a bit on start up and then drivin too now! not masses of smoke tho wat could it be it has a 2nd hand turbo on which is a stage 2 was told it didnt smoke but havent really boosted the turbo up yet as been driving slow for runing in ???

was told it would burn a bit of oil while bedding everything in but just bit worried want to get it set up now as i have covered 500 miles running in but cant afford for this to go wrong is it worth bieng set up while its smoking after 500 miles ? i know a oil change is due now but would this help or make it worse ?

spec is std engine efi ofac management, biege injectors, 195 chip, front mount intercooler,alloy rad(which i think makes it run hotter), stage 2 turbo, 044 cossie pump

 

any ideas ?

 

Sounds to me like the turbo is the unknown factor so could well be that mate.

 

yeah thats wat i was thinkin but would it smoke when the turbo has hardley spooled up also im not running the water pipes to the turbo cos it kept boiling the cooling system up but i know it should have them how can i keep the system cool with them attached?

 

Water cooling the turbo has nothing to do with your smoke, lots of us run withot it for the same reason you do.
What colour is the smoke?
Blue is oil, black is fuel, white is water (steam).

 

it could be the turbo, what i'd do is find a friend and pull the turbo off, then get your friend to hold the oil feed pipe in the oil return pipe in the block.
then run the engine without the turbo/manifold.
if it smokes it is an engine prob, if not then the turbo is to blame(ish)
check the exhaust elbow off the turbo for oil and the manifold where it bolts to head for oil also.
check the exhaust ports too for oil, you will have soot, but if you wipe your finger over it, if it's oil it'll stay wet, if condensation/overfuelling then it'll evapourate and leave a dry soot.

it could be the rings in an oval bore sadly, but you won't know till you've satisfied yourself with the turbo.

hope that help.

 

its blue smoke althought very faint it deffinatley oil

so the water cooling pipes are ok then as i was bit worried

 

 

i know its overfueling a bit as it pops and bangs a bit lol but it dont smoke all the time or not that i have noticed so if i took the turbo off would it still show how will i know if its the rings ? was told that it was reconditioned so assume the rings were done ? unfortuetly it is an unknown rebuild i just brought it

 

yeah turbo should have oil in the exhaust housing if it's the turbo, oil in ports if it's the engine.

 

will have to check wat bout gettin it set up tho ? should i wait or would it be worth doin to find out wats wrong

 

getting it setup may be a good idea, but if there is an engine problem than it'll be wasted money.

 

this is my 3rd engine i wasted so much money on it already just want it sorted so i can enjoy it plus do you ever make money on a turbo

 

LMAO!!
That has got to be the most random piece of advice i've heard for a long time!! I can se where your coming from and it may work but sounds fucking dodgy! LOL
This might be easier..... disconnect the actuator rod, hold the wastegate open with a cable tie, do as you said with the oil feed pipe, and jam a screwdriver in the comp housing to stop it spinning.
Then drive the car and see if it smokes?!

Do a compression test mate this will tell you if the rings have been done or not.

 

Turbo, valve stem oil seals, or piston rings are the main reasons CVH's smoke...

 

that will be 90% of your oil pressure spraying back into the sump then.

 

you'd only do it for a few seconds, not to run it for minutes, i have a fitting to block the oil feed for such testing and a non turbo manifold, not everyone has the bits needed to test properly.
i've not tested this on mfi, but removing the oil cap and letting it flow into there instead will cause a leak in the seal of the system and wouldn't run right then either.
it's just a method of testing the engine without the need of a leak down test as compression tests aren't always conclusive either.

ideally you need to use a non turbo manifold and simulate the same conditions without a turbo and see what happens, i had an engine which on compression tests seemed fine but on a run showed a problem due to engine load conditions.

 

i was told that it would burn oil while bedding in is this true ?

 

Just a thought but has oil from your previous dramas got into the exhaust and burning off giving the impression of engine failure

 

good point yeah alot of oil was dumped into the exhaust how long would it be visable for it dosent smoke all the time tho

 

i had a knackered turbo plumes of smoke every where thick white smoke the head gasket was on its way out aswell tho and i change the hg and still did it and took the turbo off and the oil seal had gone got a new turbo problem solved

 

mines only a bit of smoke tho and you have to pay attention to see it

 

Its a CVH your worrying to much!!

 

lol i know but to many times a bit of smoke has ended being engine faliure cant afford that
