Hi guy's I picked up an r32 gts-t and it had some dirty old coolant in it. First month i had it the same coolant was left in it and it stayed at the same level. Now i have flushed the system and replaced it with fresh coolant and every couple of days the coolant level in the radiator has gone down and There is no signs of leaking. I have a white sheet under the car to detect leaks. The head gasket is not blown (no milky oil) so it has me stumped. what else could chew coolant or is the coolant I have (repco branded coolant) the problem.

Yeah sounds like the water pump has let go in the seals. This can happen when people flush the coolant due to the fact that you can remove rust and scale that may have built up and stopped it from leaking. Could also be a loose clamp at the water pump maybe

Dunno about the RB20, but on the RB25 there is a welch plug at the front of the motor near the water pump.... Mine was stuffed... I actually thought that it was the water pump and when I did my 100K service, i noticed that it was leaking from the welch plug... gheyness.....

After getting a good quallity torch and taking a look it appears that it is the passenger side of the engine that has the leak. is this consistant with the turbo water lines and if so how much work is involved in replacing them?

Could be any number of things mate......

Best bet is to try to see where it is leaking from..... Check all hoses and connections for wetness for a start..... Try doing it on a sunny day where you get good light, or go to bunnings and get one of those $20 halogen lamps.... Great to work on cars with......

Does it leak when it is hot or cold???? Or both....

      Squeaking clutch/throw out bearing

      By patrickxdf12 · Posted

      Hello!  i just finished manual swaping my r34 skyline with a r33 rb20de box(RB71C)box  When the car is running it squeaks crazy loud and it was smoking from the gearbox area. The gearbox is fine it was tested. The clutch slave cylinder seems like it doesn't fully releases the clutch. I want to ask if this noise is from the throw out bearing or could it be the clutch assembly or disk att.xFliq87Gzw6kImKBVqDebXkj0fBqymk0JaYeP3_3SlM.mp4

      S15 Spec R

      A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always!
