hey guys,

i might have some bad news but i'll ask you guys anyway...

last night after re-bleeding front brakes i saw a small bit of oil underneath the car so i degreased it and washed it down.

after doing that i did the normal things like checked oil and radiator and found the small bubbles coming up while it was idling, then like a white milkly stuff started to surround the top of the radiator, not alot but still noticable. bigger bubbles from time to time and also when revving the engine to about 2k the coolant level lowered abit.

doesn't seem to be overheating at all nor driving any different...

dont' think i've missed anything.

any input would be great.

If you have the cap off and rev the engine the coolant level will commonly go down and return to normal when you stop. Watch for the leak to reappear. Bubbles and milky stuff bit of a concern. Try to get your colling system pressure tested (any radiator shop should be able to do it - its a 5min job.

Liek Kiwi said, coolant level varying on engine revs is normal, as your waterpump is 'pushing' (or trying to) more coolant into the block. The bubbles and milky residue is a concern. It does sound like you've got a blown head gasket unfortunately. :)

Pull your dipstick out and see if you've got any trace of a "chocolate milkshake" there. This will show coolant mixing with oil. If no oil, only bubbles, then its coolant leaking into cylinder.

If you can change the head gasket yourself, you'll save a big bundle.

Don't panic. Are you losing water, overheating? Get the pressure test done and if there is no negative result just keep on driving while looking for any more symptoms. If there is clear evidence of water in the oil or vice versa or if the pressure test shows system not holding pressure then you may need to look at pulling head off.

losing alittle water that i noticed the other day.. but i had the top tank replaced about 2-3 months ago, so it may have not been bled right.. it doesn't overheat.

i'll have to take it down to the radiator place on my next day for them to check it out.

      Big Brake Kit for ECR33

      By robbo_rb180 · Posted

      What are you doing with the car? Drags, sprints, racing? A decent upgrade of dba 4000 rotors, good quality pads (endless, project mu, intima are all I have used), quality fluid and braided lines. All have held up to multiple big track days and street duties. No need for big fancy kits as some also require significant energy to come upto operating temp. Look at 350z caliper and rotor upgrade too.  @Dose Pipe Sutututu comment on them and did a good write up.

      I've driven that one and it's a great deal and drives nice. The owner definitely treats it right on track. You would have gotten it for what you paid for this one too.   Keen to see what you do to this one.

      Front Tyres on R34 GTR, fitment, etc, *question*

      By Kinkstaah · Posted

      I have a question with regards to R34 GTR guards. All the info here is quite old. Useful, but old. At what point does the bumper itself become a clearance issue with wide wheels on a R34 GTR, specifically the part I've drawn in red here: All of the info that people post about implies that 285 is as far as you'd go before scrubbing becomes an issue, but they speak of hitting the inner plastic liners, not the bumper itself. Just how wide could you go if you took the liners out? Has anyone done it? I have been messing with my own car and spacers and heavily cursed my lack of planning, but I might not feel so bad if there's actually no gains to be had by going a GTR guard and front bar combination for $5k+ of money I do not have after spending about that much already on my solution which now has problems. (Woo) At least I now know why GTR guards and bumpers flare out like this over their GTT lesser cousins. I feel that in 2024, someone has gone further and attempted to run 315's or somesuch on the front of a R34 GTR. If you have, please post. If you're tried and failed for some other reason definitely post so I feel better about my mistakes

      URAS Type R R34 GT GTT Widebody Front Guards

      By Kinkstaah · Posted

      Genuine URAS Type R front guards in FRP. These will fit a GTT. They will only fit a GTT. If you have a GT or GTT and want wider fenders with a Z tune look up top, this is what you want. You use this with a regular GTT fitment bar. Not a GTR bar. They fit GTT guard liners and plastics, not GTR items. So if you're reading this thinking "Ah! I have a GTT or GT and want wider front guards that bolt directly on, but do not want the hassle of changing my bonnet and bumper and plastics and undertrays or anything else, this is what you want. The fitment is annoyingly perfect. I really would rather someone pick these up in person and not ship them. SE Melb.
