I am running my fresly built engine in, and keeping at 0 boost, and not going above 4k rpm. Today at the lights I noticed a heavy cloud of white smoke coming out the exhaust and then it cleared.

Drove home 20 miles and it didnt do it again.

It smelt of oil, and people were doing there windows up! hahahah

Any ideas?

v man

running 0 boost can do damage as it wont bed in properly

you need load on the engine but keeping the revs down

glockenspiel lover

yeah..you need to run some boost as this will help burn some fuel off that the engine is putting in..

The boost will help heat get into the engine and run it in better..still keep to 4k rev limit for a while but use like 8-10 psi boost..

parrot

Ok I am now starting to understand, so I basically need to run it in with slight boost (10 psi)

Is the white smoke a different issue then?

parrot

I have been running some boost put using my pedal to control it, so have been going to 5psi max and then changing gear.....

Is that ok?

glockenspiel lover

The white smoke is clean brand new oil passing the rings mate and if you dont run boost the bores will glaze and the rings will go sharp so yes 10 psi should do it..

Drive it like you would a normal cossie using all the boost but only to 4k then starting raising the rev limit a bit at a time and boost if you feel it needs it

tommytwotanks

white smoke, sounds like steam to me, so might be the head gasket is it using water

v man

i would get some good load under it a few times when out
as in up hill high gear low rpm
get the turbo pushing some boost as said around 10 psi in the engine

get the turbo working put dont go over the 4k revs

sitting at constant speeds on the motorway is not good for running in

town driving is good
stop start stop start but as i said get some good boost load on it to

just dont let it brake traction and wheel spin

glockenspiel lover

^^^ perfect way to run in an engine!!

v man

i would also do a oil change at 500 miles for more running in oil( i take it you are using a propper running in oil and not 15/50

after 1k miles then put the good stuff in it

glockenspiel lover

and i was just about to say that too!!!!lol

v man

done a fair few and fucking hate it

i get bored

once running my rs turbo in years ago when i was young i got bored after about 300 miles so wacked 2 bar through it and you can guess what happened

v man

just out of interest who built the engine as they should have given you running advise

E980VTJ

has it used any water?

glockenspiel lover

Lol!! yeah ive run a fair few engines in myself now!

I like to do about 2-3 very hot runs ie just ticking over then dump the shit oil and re fill with new shit oil and then i know the bigs and mains are pretty much run in..

Then i do say 100 miles with about 10 psi boost and 4k revs then 1 bar of boost at 4 k for another 100 miles then change the oil to something decent and 1.5 bar for 200 miles at 4.5k...
Then death!! with full boost!! it worked well for the last two cars i run in!lol

parrot

hasnt used any water no.

parrot

I am using mineral oil, which was given to me by the chap who built the engine.

v man

[QUOTE=parrot;5924486]hasnt used any water no.[/QUOTE

dont think water loss is the issue

just follow the running as mentioned and keep us posted

parrot

Not using any water, and the engine has only done so far 180 miles and has not overheated

parrot

[quote=v man;5924489]Will do and thanks for the advice, appreciate it.

I have been told to do 500 miles of running in and then change the oil to the decent stuff (dont know which one yet) then get it setup properly to what it should be.

v man

[QUOTE=parrot;5924494]i would do 500 miles and change the oil for more mineral and then the good stuff after a thousand or so and then a few hundred under running in conditions before mapping

dont rush it you have spent hard earned money on a rebuild

parrot

[quote=v man;5924505]Ok sounds good to me. Is the smoke that I saw anything to worry about?

If I am going to put it under some load 8-10 psi then shouldn't get the fuelling checked to make it is ok?

[quote=parrot;5924556]Hi ya i was posting yesterday under my mates name so got banned!!lol..

This is my account now..

I assumed(which you should never do!!)that you were on a suitable map for your spec??

What is the whole spec and what chip are you running??

You should always be safe to run 10 psi up to 4k tho and when running in leaner is better than richer so cant see a prob..

cheers danny

parrot

[quote=750hp escos;5924968]Oh I see what you are saying.
The spec is :
Siemen 55lb injectors
MSD Closed Loop chip
L8 Ecu
3 bar map
Compression 7:19:1 ratio
T34 with 48 housing
500 intercooler
BD10 Inlet standard exchaust.

It was setup before the build on Dark Greens and on a collins chip L8 ecu, which was a nice setup, then after the build put the MSD chip (closed loop) and new injectors in to run it in....

Now running the above new spec in and had a nightmare yesterday with white smoke pouring out, and then it cleared by itself........slightly worried. Have been told it may be internal water leak????

750hp escos

[quote=parrot;5925313]
Well the chip and set up if all running right should be fine to just run with around 10 psi boost mate..

If the engine isnt losing water then theres no water leak if it is then its either h/g leak or head cracked or even worse the block is cracked..

Are you using the same head and block as before??if so then i cant see theres a problem there..


cheers danny

parrot

[quote=750hp escos;5926817]Thanks for that.
It isnt loosing any water all, so that must be a good sign.

Yes using the same head and block as before, but with it all being checked and machined etc.

Just went out for a drive in it now, and was putting under a little load 10 psi and changing up and going through the gears a little and also engine braking a little.

When I got home and put the car back in the garage, i looked at the exhuast and there was a little bit of white smoke coming from the back.....it smelt bit oily to me but was white.......
The smoke was very light and was only there for a few seconds and then it was gone.....

I am thinking maybe turbo??????

750hp escos

[quote=parrot;5929205]
I still think its just running in but of course it could be the turbo..

Tbh i think your just a bit para about the whole new engine running in process...just crack on as you are and before you know it your be able to run some proper boost and if there is a real problem it will show its self sooner rather than later..

Cant remember what turbo you said now but if you want to check it then after a run but when it cooled down abit take the filter hose of and grab the nut in the centre of the comp wheel and see if there is any in and out play as well as any excess side to side..

if it isnt alot then i doubt theres much wrong with it but if theres play then the turbo needs a going over..


cheers danny

parrot

[quote=750hp escos;5929216]I think you may be right, I am being para but as I have spent loads of money on it, want it to be right!

I am going to run it on for 500 -600 miles and then get it setup, as that is what my tuner and engine builder told me to do. M

Thanks for all your advice and help mate

I would er on caution and get the sniffer on it to see if you have head gasket failure. In my experience, white smoke is usually down to water entering the cylinders.

750hp escos

He isnt loosing water!!!!!!!!!!!!!!

That would be steam NOT smoke!

If it's white smoke it's oil, on the turbo side I suspect!

Usually if oil is entering the combustion chambers it will be blue smoke!

You dont need much coolant in the cylinder to get white smoke out of the exhaust.

750hp escos

when new anti freeze gets in the cylinder it does look like whit smoke but its actually steam and if you go behind the exhaust you can smell the anti freeze..

When oil is brand new it also comes out white when being burnt especially the turbo side..

I think it will be ok now though since its got some boost and think it will run in ok..


cheers danny

v man

[QUOTE=parrot;5929728]sorry mate but imo i dont think thats enough miles running in before setting up
but its your engine

hope it all goes ok for ya

parrot

Took it for a drive last night and did around 40 miles and it was fine, no smoke and was running 8 - 10 psi of boost

Do appreciate your advice and help, top man!

parrot

[quote=v man;5930618]I have spoken with Mark Shed and he says 500 miles is plenty, he normally runs them in for 100 before setting them up.

bigad4x4

[QUOTE=parrot;5930670]yes 500 miles to run the engine in is fine, i have also heard of top tuners running engines in of between 100-500 miles! drop the oil again and prepare for mapping and then hope it holds together lol

750hp escos

[quote=parrot;5930670]No problem mate im glad i can be of help..

Mark is right to many miles running in is only a bad thing and if mark is doing the set up for you your laughing!!

Hope your happy when all done!


cheers danny

parrot

[quote=750hp escos;5930725]Yes Mark will be setting it up and making sure everything is safe.

He does know his stuff!

What silkolene engine oil should I use? Is that the best one to go for?

parrot

[quote=bigad4x4;5930690]Exactly what I am planning on doing!
