Hello.

 

Well try my best to explain this..........

 

My car when rebuilt the first time was smoking quite alot(white smoke i believe) thought thsi might be down to the amount of crap that would have been put through the exhausts.

After the engine was stripped down and removed it appears there was alot of fluids at the turbos?

 

Can anybody inlighten me on this, could it have been the turbos causing the white smoke or could it be due to the crap that would have went into the exhaust getting burnt off? what could be the cause of the fluids?

 

I sent the turbos away to silverbullet for re-con and balancing checks and i know he gets 100% feedback, so was thinking it may not be the tubs?

 

Please help if you can.

Doubt it would be the exhaust, white smoke is water, blue oil and black fuel.

 

What fluids where at the turbos? Water or oil? and where exactly was the fluid found, inside/outside?

Mikey will be able to confirm that mate, im not sure.............................

 

Reason for this is my cars ready to go back together so just need to now how it could be possible for leaks when they have just been re-con and checked etc....

any help would be great guys as the engine is being rebuilt tomorrow so just need to know what this problem could be before fitting these turbos again??

manifold gaskets or anything like that?

anybody............

To be honest, its very hard to give an idea without it all infront of you to look at.

 

Surely Mikey should know as he has everything right there to see whats what??? Mixed oil and water doesn't sound good, thats two seperate leaks. Would very much doubt its the tubs.

 

Only place I cant think of is head gasket fella where water and oil can meet AND get into the tubs AND cause white smoke.

 

Unless silverbullet has started shipping them pre filled with oil and water lol

Yeah........few chaps said that before, i think that might have been the problem, the headgasket went on it possibly thus causing what appears to be a leak?

It was a new HG supplied with the kit and had only done 30miles, so shouldnt have went but i suppose could have just been one of those things.

Yeah could have been a flaw in the gasket or poorly fitted or anything like that really. Does seem the most likely cause though.

No bother. Surely must be somethign as simple as that, as silverbullet has to my knowledge never had turbos sent back to him or anything like that.

So must be something else other than turbos, so i guess HG is where to start, oviously i wont know until the turbos are cleaned up fitted to the car and HG replaced with a new one, this way i will know once the car is running if the HG was the problem. (if you know what i mean)

 

Basically just going to have to fit it see what it could have been, but im going to guess alot of people will say HG.

You were told to discount the turbos doing that in your last thread!

Cracked heads ? were they pressure tested ?

Can only be head gaskets or a cracked head. Was the correct thickness head gaskets used to compensate for when the heads where resurfaced?

May be it as the gasket was from a kit aparently?

If the heads or even the block have been resurfaced a few times in the past then a std thickness head gasket will be to thin you must measure and work out the correct thickness of the new head gasket to restore what has been machined off otherwise you could end up with the dowels that locate the heads to the block holding of the heads by a fraction perventing the full clamping force on the head gasket.

as i said in my pm, send them down to me and i will get them re-checked for piece of mind..

 

the turbos are both oil and water cooled but, it is highly unlikely that the tubs are leaking and mixing fluids.

 

could it be to do with...

the heads and block being skimmed too much with a standard HG being used?

the engine being run with no oil pressure?

 

was the engine compression checked and leak tested before running?

 

obviously i cant say too much on the subject untill i have looked over the tubs but, what i can say is, the reconditioning went as well as all the others i have done and i trust the engineering firm i use for testing and balancing.

 

so, please, if you have any doubts about the tubs, send them back to me for re-testing

 

Mark

Graig Piece of mind, send them back to silver bullet to be checked as he has kindly offered.

 

Will be well worth stalling the project for that piece of mind.

Was it a cheapo ebay head gasket set that was fitted??

Has Mr Bean fitted the heads back on the block yet ? if not get him to do a trial fit, i.e. put the heads on the block with no gasket to check the dowels are not holding the heads off, and then just to prove its OK lift head and insert a 0.10mm feeler gauge in between head and block to see if it is clamped. If it is then a standard HG is OK. I thought in the original thread you stated the turbo housing was 'cracked', which contributed to the oil/water mix, was this not the case ? Are the original heads being re-used and have they been skimmed and pressure tested. I assume the heads were tightened down in the correct order and torque. None of this accounts for the low oil pressure, has this now been sorted as no matter how good the rest is, low oil pressure is a killer especially on a re-furbed engine with tightish pistons & rings, this exerts extra loads on the crank until it beds in.

I have no idea what your on about disconnect the turbos and that.

Plus no it wasnt a cheapo head gasket, unless the HG Z1 supply is a cheap and nasty one then.

There was a crack in one turbo casing, which i believe is ok.

Im sure mikey sha'll be alogn soon to clarify what situation the car is in.

ok no bother then mate.

Just please insure your measure and get it all right this time please:D!

so, did you want to send them back to get checked?

 

i only mentioned no oil pressure as Mikey, in another thread mentioned when he ran it, there was no pressure.

 

as an up and coming new business i naturally want to help out and sort out any problems that may arise, and would appreciate the opportunity to check out and rectify any probblems before asumptions are made publicly.

 

so please, if you have any doubts about the turbos. send them back and if there are any faults, i will sort them out.

Is this not a most generous offer, at least it would put your minds at rest especially as they have been run on an engine with oil and water mixed which would have also gone through the turbos. Personally I would snap his hand off.

Well to be truthfully honest hes said to me about the test that they have went through and hasnt had any sent back, and most probable cause is a new HG which everybody seems the problem could be.

So i trust silverbullet with the turbos being perfect really, this has all come from a suggestion from mikeys boss, who didnt see the car when it was stripped for the 2nd time. Soon as i mentioned oil and water mix everybody suggest HG and this seems the only cause, and the only cause anything like that could get near the tubs.

So it saves 130Pounds for turbo re-testing to go for the new HG. Plus the time it could take for them to get there and back.

Sorry there mate if you think im causing a problem, not atall. I trust your abilities in the turbos and believe the test they have went through before being sent has been good enough and any problems woudl have arisen then.

I havent made any assumption about the turbos or that, just asking how there could be a leak near them thats all!

I have no idea what your on about disconnect the turbos and that.

Plus no it wasnt a cheapo head gasket, unless the HG Z1 supply is a cheap and nasty one then.

 

Was it a stock Nissan gasket?

 

or was it a metal Cosmetic one?

 

Z1 supplys both.

 

the only reason why i ask is from a past experiance. A experianced engine shop done my last build supplied a metal gasket however they did not apply the right finish to the heads and block, they applied a normal finish suitable for a stock gasket.

 

Although my engine failed down to another problem a few miles down the line the headgasket would of went. When the engine came apart the gasket was in a mess and split in several places.

 

This was all down to the incorrect finish for a metal gasket.
