Gday guys just thought id write in and say its time for a new water pump, found it leaking pretty hard during the week. Has anyone elses gone at around 120k's ? Anyway my question is when i put a little coolant in to it up and let it run for like 30 secs i opened the radiator cap and there was foamy type bubbles at the top of the radiator does anyone know why that happened? Engine being to hot maybe? Also im getting it changed on Monday is there anything esle my mechanic should look at/change due to the water pump dying. Any feedback is appreciated thanks

Well if he is doing the water pump now is a good time for a timing belt change, tensioners, front seals, flush/upgrade/renew radiator. Also, not sure if its the same on an R33 but on my RB20 there is a welch plug behind the water pump which had corred a lot on mine so I guess change that as well.

If your mechanic didnt suggest a new timing kit while doing the water pump I would be very suprised.

u may as well do everything while u have all ur belts off... if ther is foaming bubbles u might also have a air lock.. if its really bad and cant fix it.. u might have to rip ur head off and recon than. careful not to blow ur head gasket in this weather. or u will rip ur head off.. then u can get ur tbelt cam seals front seals tensioners all done.

how do you know what the water pump has carked it? leaks all the coolent, and temp goes skyhigh?

Well with mine there is a small hole under the water pump, (built in safety item) when the seal goes on the water pump water will leak out of the hole under pressure. I had been using a little bit of water, We did a rad comp test, changed hose clamps and still could not find the leak, Then one morning when I started my car I noticed a bit of coolant coming from under the car, and when temp built up it would stop leaking, I then decided to check the water pump. Anyway that’s on my RB26.

Mine's just going at 115,000km..

bubble, bubble.. Hopefully yours hasn't cracked the head or blown the gasket..

I've always stopped when its got to 3/4 on the temp gauge.

most people change it @ 100k... as thats what the 100k service involes.

Going another 20k is asking for trouble!

;)

Wow that was a big reply thanks guys, cars now back on the road. When i bought the car it just had the timing belt done but i dont know what else. My mechanic did a pressure test and everything was ok but i dont know if the tensioners were changed by the last owner. What sort of damage would happen if they fail or what are the signs of them going? didnt have enough money to get them changed this time :blink:

    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go. 
    • More so GReddy oil relocation kits, sandwich plates, etc. all use 10AN fittings. And same, I've only used 10AN and my car sees track work (circuit, doing laps, not 10 sec squirt business).
