well was driving my r34 GTT today, and notice the oil pressure was looking a bit lower then normal, and not rising much. So thought i check oil and for ne leaks, etc.

Oil is all good, but my coolant is a Coffee looking colour. All i can think of is the head is f**ked?

Whats other things u guys reckon?

Cheers

Justin

I would thoroughly flush the cooling system with a flushing agent, and fill it with water. Drive it for a week and see what happens. Did you just buy the car, or do you have some other reason for suspecting head/gasket. Has it overheated, or making big power? RB heads are pretty tough, and dont crack often.(except RB30)

Dont jump to conclusions its a headgasket straight away.

Brown coloured coolant is usually just a sign of rust build up in the coolant galleries. Get your cooling system flushed properly (power flushed at a rad place is good) and have it pressure / leak tested. Replace the thermostat and coolant and u are good to go for 12 months.

If your coolant level is not dropping and the engine is not getting hot then i would be hopeful that your head and gasket are ok.

As others have advised drop a can of radiator flush in drive the car for about 30 minutes drop the old coolant out, fill with new coolant and see what happens after a week. But having the radiator services is top advise and should be done aswell.

      Powder coating wheels

      I'm interested if anyone agrees with what you've said, and can give a good reason. Temperature of powder coating should be below any temperature you'd use to alter the wheel structure.  Powder coat typically 200 to 250. Annealing if that's what people are claiming would be occuring, starts at 300, and depending on the alloy, can need even up at 400+.   That's the only part I can think of that could cause an issue that people are believing it's from the rim losing hardness and becoming too soft.

      One Headlight isn't working - Driver Side Fuse Keeps blowing

      By MBS206 · Posted

      Negative probe should be on the cars chassis. Positive on the wire.   Start as said above by unplugging everything (unplug the lights, and switches. Now at the switch, there is a wire from the fuse, to the switch, so out your positive on that terminal. It should read open circuit. If it reads something, especially a stupid low value, the short is somewhere between the fuse and the switch. If that's fine, now put the positive probe on the wire that goes to the headlight (at the switch plug). If it reads stupid low, the fault is from the switch, to the headlight.   Another quick test, is take the whole LED light setup from the left, and plug it into the right side, does it still blow the fuse? If you put the right hand side led light setup on the left hand side wiring, does the left hand side wiring now blow?  If the blowing fuse swaps from right to left doing this, your LED lights are the issue.

      Anyone know if it's a problem to powder coat forged alloy wheel centers (Rays/Volk GT-C). some say it's bad and can damage the alloy, some say it's not a problem.

      One Headlight isn't working - Driver Side Fuse Keeps blowing

      By kevboost7 · Posted

      Hey guys, I'm reviving an old post but I'm finally getting around to working on this now. I removed the battery to get a better look at the wires and i traced the wires from the headlight to the fuse box in the engine bay, but the wiring looks fine? The wiring for the R/H headlight is 3 wires and then is bundled up with the large diameter wire that goes underneath the fuse box. I didn't take it apart yet. I know you said that its a short circuit somewhere between the fuse box and the headlight. But could it be the headlight switch on the dash? Also, i pulled out my multi-meter and set it on the Ohms, but i'm not sure where to put the negative probe and the positive probe.
