Leaking Coolant/oil Badly

[icydude]

Hi guys, I drive a 1990 R32 GTR. Unfortunately, there's coolant draining out when the car is running, not from the heater hoses or rad hoses, but rather somewhere underneath the intake manifold near the 4th/5th/6th cylinders. There's also oil down the side of the block. Any ideas what's wrong?

Most probably a welsh plug has rusted through although that would be water only, maybe 2 have gone and thats why theres oil as well. In that position, your up for alot of work just to get to them or whatever the problem is, as the intake manifold would have to come off completely, the welsh plugs are quite easy to replace though

alot of peoples oppinions is headgasket.

It would make sense if the headgasket wasn't sealing correctly and the coolant system pressurised.

with the oil in the coolant(on the rad cap) its the only possible solution.

yeah could be head gasket too, or even a cracked block if you are really unlucky. But start with the welshplug theory, get it up on a hoist and check them all out.

Is the oil a seperate leak? coming from the cam cover gasket maybe?

sounds to me like the same problem that I had with my car - the welsh plug was rusted like a mofo, and it leaked through there. Im not sure about the gasket, but take it to a reputable mechanic to get it checked out. If its not under warranty, be prepare to pay a fair bit. Good luck bud.

we removed the head and wow is that ever a pain in the ass job to do.

the intake is such a pita and the coolant lines over on the turbo side are disgusting.

Turns out the coolant was coming from a hose underneith the intake manifold. The oil has made all my coolant lines soft and one finaly burst with the pressure.

So now that just leaves the coolant in the oil.

We are replacing the head gasket and bolts and hoping that clears the problem up.

The oil down the side of the block was just the valve cover:P

At least this has allowed me to find my vaccumm leak:)

just going to change all the vaccumm lines while the manifold is off.

I told my buddies it would be easier to take the motor out but they said no the head is always easier
