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 :)

    • Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.
    • Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)
    • Those comp test results are not hideous. Whether they are accurate or not (ie, when that comp tester says 140 psi, is the real pressure120, 140 or 160?) is unknown to us. The state of the battery used to crank it over is unknown, etc etc. Many people around here would say that the absolute values and the spread are perfectly fine to just add boost and keep going. I personally would be happier with a narrower spread than that, but even the diff between 125 and 145 is not terrible. That one cylinder at 125 though, has probably copped some damage relative to the others. You should inspect the valves seeing as you've got it open. Do you know how to measure installed ring gaps? That, and an inspection of the rings themselves, is how you will determine whether they need to be replaced. If you're not good to do these things, take the block and the pistons and rings to a shop that is, and ask them for the go/no-go on them. Do the bores need a hone at all? If so, you might well be justified in getting some different pistons in order to get away from the ring supply problem. Whether you're happy to spend a lot more money right now, on more gear, rather than less money, but an amount that looks stupid given that you will only get a handful of rings in exchange for that money, is for you to decide.
    • also possibly backed up to my filler and shat down it! 🤣
    • Ok so i would love some advice here please, i purchased an R33 a few months back and its had a few mods done to the engine, its an RB25det running a Master ECU, 1200cc injectors, bigger turbo, oil cooler, oil filter relocation kit, Spool H-beam rods, acl/ross pistons. When i removed the motor from the vehicle (as its getting a respray) i thought i would compression test it and these are the following results. Cylinder 1-145psi, Cylinder 2-143psi, Cylinder 3-125psi, Cylinder 4-145psi, Cylinder 5-140psi, Cylinder 6-135psi this test was done with the motor on the ground and powering up the starter motor. I dropped the sump and found broken oil squirters on cylinder 3,5 and 6. I was told my rings are probably worn so i stripped the motor completely to get a new set of rings for it. The trouble is no one has these rings anywhere and they have to be custom made by Ross over in the states and will cost about $600+$200 delivery. My question is how can i tell if my rings are at fault and if they are still ok and is this price ok for a set of rings?
