Oil in water but no water in oil.

[Nottswoody]

As title says guys..

We're would you start looking? Iv cleaned it all out once but it's returned in my tank.. Also seems I'm loosing a bit of water.. Head gasket? Radiator? What would you do guys? Drives fine boosts well idles fine and starts fine.

[Dave Reed]

Have you got the standard rad/oil cooler setup?

If so I'd start there.. Could also be turbo

[SCHWARTZ]

Id look at rad if you have just re-built the engine, try pressure testing the rad to see if it leaks.

[Nottswoody]

The rads fairly new re core jobbie is it a case of putting the pump valve into a header tank cap and pump away?

[Nottswoody]

If it is the turbo what part would it be? Expensive could I doit my self?

[Romil Davda]

The OE rads have been know to leak oil into the water system (oil cooler built into rad), this would be my bet....

[Jonny5]

Cracked head or head has lifted off block :sad2:

I hope it's that as its a easy fix :)

Thats not a nice thing to say about Paul's drug taking habits...

Oh, cracked head!!! my bad.

Well he does spend all day counting them :laugh:

[Nottswoody]

So we're basically saying it could be anything lol
I have a spare head
I have a spare turbo

Bloody cars I can see me pigeon holing this 5 for a very very long time..

[Nottswoody]

Or should I keep going to it pops :)

[SCHWARTZ]

i would take the water hoses off the rad block one outlet then knock something up to fit an airline to it and pump it up. not to much shouldn't take a lot to see a leak

[RussellT]

?cracked liner:cry:

[5teve L]

I had this years ago, my rad or oil cooler had split causing water & oil to mix, ended up in my header & then all over my windscreen through my louvred bonnet :wasntme:

I still blame James as he gave me the rad :cooter:

But how would I see the oil leak?

[Romil Davda]

Once your pressurised the system, you will know if you start loosing pressure (as the pressure will drop)... If it holds pressure, your ok, well the rad anyway.

I'm thinking it would be easier to take the rad completely off block up the oil threads then pressurise it? Saves me getting water in the oil?

I just can't get in my head why the pressure Is going one way? Would it not just mix both oil and water into the hole system?

God I hope this is cheap iv got a nipper on the way that's why I did this last year.. Otherwise this 5s off the road for a long long time

[Markey Mark (BD)]

I've had this before in my old campus and seen it before on few 5's, ended up being crack in the head.

i had mikes retapped and pressure tested monday, they pressurised oil gallery to 80 psi and all was sweet no leaks but pressure test water part of rad you will fubar it they can only take 10/15psi max be warned

[SCHWARTZ]

oil is at a higher pressure. drain the rad and just fill with air you may get air in the oil but that it.:laugh:

[SCHWARTZ]

or pressure the the oil side either way if theres a leak it wont take much to show a leak.

Oh dear..

It makes me think did I really tighten them correctly? Pitty as I spent bloody hrs gasket matching it..

Guess it won't last till after blyton lol

Next question is could I swop my other head off my other engine? No issues with that one and I only had it skimmed a few months before taking that engine out..

id test rad first its easier than head off mate

[Nottswoody]

I will bud don't you worrie.. I noticed a little rust and I mean little in the bottom corner when I had the engine out but that wouldn't be it as it was the opasit side to the oil. But everything iv read so far says oil split in head.. :cry:

At this point iv gave up lol babies are my efforts this year :)

[R5MJH]

i had one tested monday they tested it to 80 psi ish and there should be no leak off, if this turns out fine id be looking at what mark says mate

[Brigsy]

Cracked head.

[TNT ANDY]

Like previously stated - check rad 1st

[Tony Walker]

oil gallery in head cracked or leaking rad. its where the oil pressure is higher than the pressure of the coolant.

[Nottswoody]

Thanks guys I hope it's the rad that would be easiest fix and if not I have another head.. Is it possible or worth fixing the head?

[Tony Walker]

i think it can be drilled and sleeved but i dont know whos done it, my head was the same when i bought my 5, just slapped another head on. was it doing this before the rebuild? is this the same head you had originally or a different one? has it ever overheated? heads dont just crack without a reason really.

Different head tony my other engine is still in the garage together I wanted to keep it as a good spare really but if I need to use it so be it..

Not really over heated never past the third notch and defo never seen the light..

[casper]

Paul,try and get Mr Smith to have a butchers before you do anything. May :sad2:be fook all.

[Nottswoody]

Lol it's far from that bud its loosing water and full of brown scum but the coolant is clear.. I will have a day onit this weekend and try the other things first.. It's a good excuse to get back on my bike anyway :) I can do this I'm sure mr smith is a busy guy

[NRG]

New poster! (less than 10 posts)

Did you put sealant on liner seals ? I've seen liners seals leaking into sump before.
I.e water in oil but no oil in water.
I'd unscrew oil pipes on rad and pump the water system up. If water comes out of oil holes in rad your sorted. If not I'd take sump off and do the same .

[Tony Walker]

put a pic of the expansion bottle and the crap in it.

[Nottswoody]

Will send it on FB mate can't doit on here

i had a few done a few years ago, by an old boy near where i used to live. charged me something extortionate like £40 a pop. basically he drilled it out and fitted a brass tube covered in some horrible green glue (might have been somesort of epoxy resin). worked a treat.:agree:

[Tony Walker]

To be fair paul... i drove mine for nearly a year like that.... its not ideal and it will damage hoses due to the oil being in there. Did the headgasket twice thinking id done it wrong first time. mine was bad enough to make my coolant a complete oily gloopy mess no coolant whatsover still drove fine for a very long/hard time. (this was before i was a mechanic, and part of the reason i now am a mechanic lol)

[Tony Walker]

Its not bad at the moment looking at your pick.... usually cracked head it keeps filling it with oil. id say drive it and monitor it for awhile. it may just be crap in the system somehow.
Have you re-torqued the head too?

I have since rebuild and one bolt was a good full turn loose passenger side front bolt.. I need to check again when I get time..
I'm picking a rad up tomorrow so that's an easy check
I completely flushed the car three times even just had the hose going though it for ten mins and then ran it and within a day it came back just the same

I'm getting the rad as back up really first I will re touq them again then see if that works if not change the rad and if that doesn't doit.. The heads coming off.. Still hits 1.6 daily lol

[Tony Walker]

passenger front bolt is pretty much where the oil gallery from block to head is :disagree:

[Nottswoody]

Must be the boost :) I'm going to lock tight the dam thing if it is that I was worried I pulled the thread last time it did tighten up though.

[Nottswoody]

Well iv checked the head bolts and there still tight so it's not that re set my tappets so tomorrow change the rad for another one see if that sorts it if not then off with its head.. Or I might just keep it going to after blyton when its coming off the road for a couple of years anyway.. The mystery continues :) still boosting it :D

[Tony Walker]

looking at the pic, it really wasnt that bad.... id drive it till it gets worse and you can diagnose it properely. guessing at stuffs just a waste of time... might as well enjoy it for a bit and just keep an eye on it. As i said my coolant system was more oil than water for over a year and it was fine.

Are you being serious?? All that work to just take it off the road :scratch:

[Nottswoody]

?cracked liner:cry:

Correct after all it was the cracked liner

[RussellT]

Sorry to hear that anyway a good excuse to build a better engine.

[Nottswoody]

I'm b18ft now russle 215bhp adaptronic much happier with her now..
