4age water and oil problem

[slidn_ways]

so the problem is i'm am getting water mixing with the oil.
the details are..
the motor is a gze from an ae101, which i converted to a turbo setup.
at the time this was being done i changed it to a bigport head with new head gasket.
after getting it back from the mechanic it took some time before the ECU side of things was done.
when i first got it running, it was ruff and had a miss ( due to a fkd injector)
this was only for about 2 minutes. and then checked the oil level, which was milky. i looked under the top cap and it looked like sludge. this was brand new oil.
so i drained it and put more in, and the water still seemed to be there and increasing.

i have considered the following,

the turbo water and oil lines being wrong, but they are all in the right place.

the turbo housing being cracked internally?

the head being cracked, however the head was sent off for valves and a shave, so i am assuming it was checked, but will send it off again

and the head gasket being on the wrong way,

....so now the head is off the motor the gasket is on the right way and looks to be in a fairly good condition, and apears to be a metal cometic item.

what also might be of interest is the coolant wasn't filled all the way, as i found this problem midway through.

so i'm out of ideas, so any advice would greatly be appreciated.

Is the car overheating at all?

[slidn_ways]

the engine was running fine as a gze smallport and now that it has been changed to a turbo bigport i'm having this problem, also the motor really hasn't had a chance to overheat as this problem has prevented me from running it.

LOL sounds like tristan...

Who did your wiring in the end?

Like i said to Grant its pretty hard to screw up turbo oil and water lines, especially on a t28... They are all pretty distinguisable. Think about the acutal amount of water in the sump, and in 2 minutes running time there is NOT alot of time to ditch liters of water into the sump unless you have a VERY serious problem, like a collapsed cylinder. Id be checking really really obvious things, like the turbo lines. But if thats your problem id say that guy Matt who did your head had the last laugh....

[slidn_ways]

hayden wtf did matt do to my engine i'm going backwards.
i ended up finishing the wiring myself, and replaced the front half of the factory body wiring so everything is neat now and in order.

the amount of water was so significant that i thought it had to be a major leak or lines mixed up, it seems to all check out.

i'm sending the head off to have it pressure tested, just to be sure.
i was also thinking is it possible the turbo is putting the coolant straight into the intake and sucking it into the head?
or do you reckon it was coolant left over in my sump and i didn't drain it all out and i have over reacted like a mad man.............? pulling the head of the motor...? hmmmm seemed like a good idea at the time? oi...

anyway what are you driving now?

[ONETEN]

DUDE!!!

Number one, COOLANT SHOULD NEVER BE FOUND IN YOUR SUMP!

Number Two. If your intake is filling with coolant, there is no way for it to enter the oil system unless you have a MAJOR problem. If it is getting into your intake DO NOT run the engine until this problem is fixed. Water does NOT compress and the block will throw a leg.

Number Three. Get on your knees and pray that this is being caused by a fucked head, as thats probably your easiest way out of this problem. Unless Matt but the head gasket on backwards.

Lol are you sure u synced the CAS properly and the motor isnt runnin backwards???
That could probably do it

be very careful either way

My sig has my current rides in it.

[ONETEN]

oh look its a double post

[slidn_ways]

i'll pray everynight before i go to bed. lol
but the head "should" have been pressure tested when it was "sent" off to have valves and clearances done, but i'm checking it again.

i love burning money.

if its not the head i might just sell the car, cbf with this shit anymore.

[ONETEN]

ill give u 4k as is if you decide to sell up

Is your turbo oil drain in ur sump conected to a water line?

[slidn_ways]

the turbo oil drain goes to the sump, not sure if its hooked up to a water line?

[ONETEN]

u need to get someone to look at it mate

[Starfire]

My guess is the turbo lines.

You could always remove the turbo, blocking off or bypassing any lines going to it, and then check whether any coolant is getting in to the oil of the now NA motor.

After that it's just a case of making sure that the turbo is ok and plumbed in correctly.

Don't whatever you do run the turbo without any lines connected to it, unless you want to be buying a new one

Cheers,

the turbo is a bb t28,
oil goes to the top and out the bottom and water goes in the side and comes out the other side. does this sound right?

[Starfire]

No idea.

The other thing you could do is:

Disconnect the coil (you don't want the bastard starting during this).
Disconnect the oil return from the turbo and put it in a clean bucket.
Disconnect the water return from the turbo and put it in a clean bucket.
Crank the car over a bit.
Check the buckets to see what is in them, and what condition it's in.

Cheers,
