After my car being off the road for 6 months I am just doin the finishing touches to get it roadworthy...........or atleast thats what I thought!

When I filled the coolant system up today and started the engine the majority of the anti-freeze/water I've put in has ended up in the sump

Put about 8 litres in total,thought must be leaking,but no leaks

Pulled the dipstick out and pink(Silkolene oil)mayonaise started coming out of the dipstick tube,switched engine off and took oil filler cap off to see full of the same pink mayonaise
It started running out of the breather pipe off the Bailey breather too

Has anybody heard of the oil cooler/modine failing????????

Otherwise it must be cracked head/block,but how would this happen when car has been parked up for 6 months

Only work I've done on engine is change inlet manifold,fit re-con turbo and fit new cambelt and tensioner,none of these can make the oil/water mix prob

Help please

CosKev3

Oh yeah,and the car is ticking over perfect,no missfires or nowt

dojj

has it got an oil/water cooler?
it might be mixing in there
or else it's head gasket gone as best case scenario me htinks

or, it could just be the condensation built up in the engine from it being parked up for so long
have you changed the oil and seenw hat came out?

Cossie-Iain

head gasket I would say just cos its been sitting about

CosKev3

Yeah standard oil cooler sandwhich plate fitted,thats what I'm hoping is the problem

Changed oil and filter earlier this week,oil was fine

Deffo not condensation,put 8 litres of coolant in it,most of it is now in the sump

CosKev3

Is that from experience m8,or just because thats what usaully causes oil/water mix??????

Its got a WRC multilayer head gasket,so would hope 6 months sitting about wouldn't affect it

Anybody had the standard sandwich cooler fail before?????

SPADGE

Did it have anti freeze in it when it was sat for 6 months?

dojj

iTrader: (3)

it's a fairly standard fault on the vauxhall V engines and i know that ford have the same sort of setup so it's the easiest thing to change

CosKev3

Yeah it did m8
Also has been inside for the 6 months

Have you ever heard of the oil cooler fail on a cosworth before????
Spoke to a m8 that works in a garage and he said its quite common on VW's.
Goin to take it off at weekend for a look

CosKev3

Thanks,will whip it off at weekend and have a look

Fingers crossed

SPADGE

Never known a warmer to spring a leak internaly mate no Hope it is that as its a nice cheap fix

CosKev3

Oh well,just have to hope theres a first time!

SPADGE

Sorry to be the 'spectre of doom' mate but the more i think about it the less likely that is to be the problem
I would whip the head off if it were me

CosKev3

Oh dear,appreciate your input

What would you say could have gone on it just from standing??????
Just can't understand what could have gone,engine is 200 long studded block with WRC head gasket,engine done 20 k
Ticks over perfect

The coolant was disappearing real quick out of the header tank,had it running about 15 mins and it started to push the mayo out of the dipstick tube and the Bailey breather

If the modine looks ok, just check the torques on the head bolts and make sure they're still all tight.

Mine kept coming loose, but always ended up in catastrophic head gasket failure , without ever mixing oil and water. Contrary to popular belief i believe that 6 long studs and wrc head gasket is really not the way to go.

How old is the block out of interest?

CosKev3

Hi m8,block is 3 years old,done 20k.

Why don't you think 6 studs and WRC gasket is the way to go m8?????
Engine was built by Bluesprint Engineering

NMS Badboy^NUTTER^

Give me a tenner and i'll tell you

Lloyd

check the oil return pipe from the turbo to the sump.it could be mixing inside the turbo its one of the things you changed

CosKev3

Cheers m8
Thanks for the info via PM

Thanks for that,will check it
Have you heard of this happening before??????
Only trouble is I've got about 5 litres of coolant mixed with my oil,so its goin to be in turbo oil return anyway
Suppose it would show if I pressure test coolant system????

doesnt sound cronic if it ticks over fine, touch wood it is just that oil/water cooler thing!

nothing worse than putting in 40 quids worth of oil and chucking it straight back away either, done that

CosKev3

Fingers crossed

Is a right mess in engine now,and in rad
Will take some fookin flushing

alan rainbow

standard oil coolers do split kev i had one go on a rs turbo only found out after i stripped the engine did you new diff mount make any difference was the old one soft

foreigneRS

did the coolant system over pressurise? if not, chances are it's not the block or the gasket, as when they have gone combustion pressure usually gets into the water jacket.

it's quite rare for just oil and water to mix, but can happen. normally not in any quantity though, and from how you describe it there seems to be a lot of mixing happening that would suggest the modine to me. fingers crossed.

Ryan

got a modine if you need it kev.

CosKev3

Thanks for the info m8,gives me hope
Old diff mount was well knackered,new one holds it real tight
Will let you know what its like when I finally get it on the road!!!!!!!!



No m8,coolant didn't pressurize at all,had header tank cap off cause I had only just put coolant in.
Got more than my fingers crossed m8!!!!!!

CosKev3

Have PM'ed you Ryan

Lloyd

i still think it will be the turbo.

twitchyrear

sorry to hear this kev,hope its an easy fix for you,you don't deserve this after the way you have looked after her

good luck

CosKev3

It is a possibility yeah,but have spoke to place that re-conned it and they very much doubt it,said the core would have to have collapsed for that amount of coolant to get into the sump,and the turbo is spinning freely with no oil/coolant in the intake hoses


Cheers m8,should know tomorrow

svony

iTrader: (3)

I hate to say it too but it may very well be your turbo. Samething happened to me, replaced the headgasket twice before realizing it was the turbo.

Good luck, hopefully I'm wrong and it's something simple.

Turbosystems

balnk off the water feed to the turbo clean out the cooling system and engine and try it

CosKev3

Thanks for all the input

You were right m8!

Turbo is the problem,removed the oil feed to turbo and removed the oil return pipe from the sump(drained out atleast 6 litres of coolant from here )filled the header tank and the water poured out of the turbo oil return pipe

Turbo is now off again,boxed up and ready to go tomorrow

Any recomendations on what to do/use to remove all the oil/coolant mix from my engine please?????????

Radiator shouldn't be too hard,hose through it and run it up with rad flush in it should do the job

svony

iTrader: (3)

Glad you got it sorted.

As for removing the oill/coolant from the engine... I drained the sump bought some cheap oil after putting everything back together and ran the car with that until it was up to operating temp, then I drained that oil, did this twice and them put the good stuff in and all was well.
Don't forget ot replace the filter.

Good luck.

Wes

CosKev3

Cheers

Not to bad to clear out then

Will get a couple of gallons of Ł4.99 oil for the job

Lloyd

glad to help , just hope it was the first thing you tried and not the last

CosKev3

Was the second thing I tryed

First only involved removing the oil filter,which has to come off anyway so no time wasted

pee vee

so you filled the WATER header tank up,
and water poured out of the turbo OIL return pipe??
(with turbo removed?)

I dont understand how the turbo is the problem mate
surely water shouldnt pour out of the sump return if you fill the header tank up?


or am i misunderstanding and being stupid

CosKev3

Spot on m8,that was my problem,all my coolant ended up in my sump

Turbo core must be cracked/got a hole in it

The oil/coolant is mixing inside the turbo core

pee vee

ahh i see!!
fook.. thats strange isnt it. must of happened on the last drive before you
put it away then?

glad you found the problem,, not exactly a cheap fix though is it

Carlsworth

fucking hell,.....

never heard of that happening before,....you absolutely positive its that matey????
must be one hell of a fooking crack.....
