Need Help Water Spewing Everywhere!

[Dose Pipe Sutututu]

Hi All,

Decided to do a radiator flush on the weekend, used rad flush, went for a drive, then yes to my surprise something had to f up on my RB20DET.

At first I thought it was the heater hose, but it turns out its not... its leaking near the starter motor but I could not see properly so I resorted to my camera phone.

When I re-filled the radiator, and put the car on jack stands I could see it leaking towards the firewall but I still couldn't see the source.

Could someone help me identify the leak? I hope it is as simple as a welsch plug, but regardless I still have to remove the plenum to do any work, there's absolutely no space in my engine bay (RB -> S13).

Many Thanks Guys and Girls!

I need her ready for the OzMazda motorkhana!!

More Info:

Leak seems to be coming from rear driver's side of motor. It seems to be dripping from above the starter motor, from the phone photos, it seems that the hoses are not blown or leaking but you can see there's previous water/coolant marks on the block somewhere..

Could someone provide me with all the welsch plug locations? Even a diagram? would be sexy if you could!

Frankly, I can't see anything useful from the photos. But I still have my money on a hose. If the engine came straight from Japan, then it's more than likely the hoses have rotted from the inside, due to a lack of inhibitor (not a favoured additive by the Japanese motorist).

You need to get the system under presure so it leaks. Either have the engine running, or get it to a mechanic or radiator place and have the cooling system pressure tested.

Welsh plug map won't be much use, because you need to remove manifolds to fix anyway. And you are better off replacing them all at the same time.

I know those photos are crap, but there's literally no room to see anything.. All I could see under the car when it was on jack stands was water pouring down from the starter motor.

Well regardless, I'm planning to take off the plenum tonight, only way I can think of to reach the leak area.

There are lots of water hoses under intake plenum. Some are really hard to get to. Could be those.

last night's progress... looking good, removed plenum, intake manifold to reach the leak.

Turns out it was the 8mm hose underneath the 2 heater hoses. It's situation between the firewall and the block.

Got a mate to grab generic reinforced 8mm hose to replace all of the hoses, even the good ones.. Going to prevent this from happening again!
