Hi

Last week I went for a short drive and floored it couple of times on high boost setting. The next day I found coolant under my car. I did not see where it came from.

I added about 1.5 liters of coolant mixture and went for a drive without revving over 4K and on a lower boost setting. I haven't lost any coolant after 100km of driving.

Do you guys know what the problem could be?

S2 RB25 ,bolt ons, Link, 300RWKW, standard internals including head gasket.

Cheers

The water temp was fine. It was just a normal drive except I went to red line on 2nd and 3rd once. Now I remember there was some coolant on the ground under overflow bottle and some under the engine (should have told you that before). Overflow bottle is almost empty now.

I just hope it is not lifting the head because of detonation or anything like that.

The car has aftermarket radiator, but no oil cooler.

I have the same kind of problem, only leaks sometimes when the car is turned off... Mine looks like around the back of the engine area as it drips from there. Also can't find where. I figure maybe it's a split in a hose that leaks under pressure...

Similar issue on my 32R.

I "modified" an existing radiator cap so i could feed pressure from my compressor. It was simply a male air house coupling hot glued/tapped into the top of a spare radiator cap. Then set to around 9PSI which allowed me to sit beneath the vehicle whilst pressurized. Dont push any more then this through though.

In my case it appears to be the seal inside of my water pump but this was only occurring at full temp and only very rarely.

Otherwise take it to a professional and have it leak tested :)

      What should I do next to hold the head on

      By Gareth87 · Posted

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
