The car doesn't burn white smoke. Compression is 180 across all cylinders, the car idles perfectly at 900rpm and 14.5afrs. It's a ka24de-t. Any thoughts on why my oil and coolant are mixing? I really need some help here.

I went into boost once and herd a noise like someone threw a metal coin into the engine bay. Not sure what it was.

blown turbo?

[shift_down]

Would that cause the coolant to leak into oil? Also there is no smoke coming from the turbo.

I don't think a blown turbo would cause the coolant and oil to mix, I would imagine that the coolant and oil passages are completely separated by walls not seals. I would take that head off to check the head gasket just to make sure it isn't leaking through anywhere from there.

[KoukiMonsta]

head gasket would lead me to think a loss in compression. that seems odd to me...

but i think your gonna need to pull that head off.

[Kallixtos]

Head gasket? Could be a small crack in water jackets. Pressure test the cooling system see if you have any water going into the cylinders. Check the plugs to see if the condition of the tips looks different than any of the other.

What about intake manifold gasket? Would that cause anything like this? I can hear a whooshing sound in the back of the intake mani.

Thats why blown turbo is my first guess.....

[Kallixtos]

It wouldnt be from the intake manifold there's no coolant or oil running through there. I wouldn't be running the car, you don't want to cause anymore damage to the bearings or cylinder walls in case its something simple.

I've heard of cases where compression is not lost even with a blown hg. Is there a test I can do to rule out or rule in a blown hg?

The turbo is rebuilt with dsm parts, only 20 miles on it so I doubt its the turbo. Also, when o first bought the car (pre turbo) I changed the oil and there was no coolant in it. So it must be something new. Just can't figure it out.

so the turbo was rebuilt, who did the rebuild?

[shift_down]

Some guy off eBay. <----- noob decision and possible culprit.

The turbo is oil and water cooled, ooooo could it be? I doubt it though.

Water and oil are encased in separate housings.

Should pull that head off and eliminate that first then do everything else as suggested above with cracks along the coolant path walls. It doesn't take very long to take the head off, less than thirty min job.

[Edwin562]

i would check turbo first.... :)

[shift_down]

Ok, I have to pull the turbo mani anyway. So ill due that and run water the coolant ports and se if it comes out of the oil ports. If not, then ill pull the head. Valve cover and upper timing cover and dizzy are already off, so it won't be too bad. I'll update this thread. Any other ideas guys?

Not sure if trolling or has seen this before:confused:
I tested the turbo and its good.
I pulled everything off the top of the motor except the cams and head bolts. Will finish it up tomorrow and let you guys know.

I really do appreciate the help guys.

[shift_down]

^ amen to that. It's such a pain. I had the head half way pulled anyway and decides to go ahead with it. Pistons looked good, head gasket looked good also, although it was wet.
Pistons were clean, no coolant on them.
The car never drove, just idled in my driveway mostly.

I'm lost right now...

Is the head broken here or is this supposed to be like this?

Is the bottom tensioner supposed to be connected to the guide? Or is it broken?

THat certainly looks like poor headgasket seal, or a server jacket crack. Then again I'm not on a good screen so it's hard to see the HG, but it just seems as if it's bad.

[OrangeVirus1]

fyi, you can have solid compression and still have a blown head gasket. Head gaskets don't always blow on the part that seals the cylinder to the head.

and like someone else said, It's almost impossible for the coolant to mix with the oil via turbo since the Shaft / oil supply is in its own housing and the coolant goes around that housing. unless you can crack 1/4 to 1/2 inch iron.. probably not gonna happen.

I wad told a bad pcv could be a problem, so I pulled it and cleaned it:
