Hey!

I have a coolant leak on the passenger side of the engine.... well thats where the drip is under the car anyway...

Me and a mate originally thought it was that stupid 3inch hose on the drivers side (thats a bitch to get back on too!!) But after starting up...theres still a leak...

Thinking it may be the hose feeding coolant to cool the turbo... (or hoping, coz i don't want it to be the water pump!)

Has anyone else had a similar problem?

Understand its a pretty stupid question, as everyones car is different....but if theres a hose thats prone to go on the RB20DETS it may help me out.... (have only owned car for 3 weeks....its my first turbo too...)

Cheers for ya help!

James

if its time to change timing belt its not a big deal if its water pump.You can presurised water system by testing pump and have a look when engine is not running.I have engine in garage I can have a look what is on passenger side anyway.Give me some idea where is leaking from.

If its the water pump, wouldn't it be leaking out fast..? Coz its just a drip...

Underneath the car it would be lined up near the turbo area...

Its strange, because i noticed the leak two weeks before it decided to over heat, and it was fine in that two weeks, then all of a sudden it went three quarter hot. When i looked under the car, it was dripping faster.... But now its just back to the minor dripping...

Hopefully that made sense.... :)

Yes they do. I just did a search for "coolant leak" and got this thread, my R33 s2 dropped about a litre of coolant today, and that's just after having the coolant system flushed and replacing the water pump! So it's not the water pump.

I'm buggered where if i know where it's coming from, the farthest i can trace back without starting to pull shit apart is the top of the left engine mount; I noticed a drop of coolant there. Basically what JC said, for all the world it looks like it's coming from the air side turbo / something very close or feeding to it. The other strange thing is it seems to only occur when the engine is cold... However this could be cause it evaporates from the heat before it has a chance to reach the ground/engine mount/whatever.

This just after I think everything is fixed! god dammut. Somebody help us! anyone with their motor pulled half apart around? If not it'll be me tomorrow... I'm meant to be going to the damn Indy and I have a 600k trip to do to get there!

Okay so I just had a quick look on fast... IF it IS coming from the turbo, which i reeeeeeealy hope it isn't, it would probably be leaking from either of the connections circled in red

As I said, I reeeally hope it's not that.. but then, I'm not quite so sure what i'd prefer it to be...If anyone else can shed some light!!!!

Hmmm yeah jezzerr....I was thinking its that too...

But mine happens after it has warmed up....i just started it then and let it idle....after a couple of minutes it started to drip... i had a look underneath, and i can see coolant around behind the water pump, but it drips on the passenger side of the block..not where the pump is...but i guess it could run there....

Could be just a gasket?

How much do you reckon it would cost to get the pump replaced...and the timing belt since you have to take that off...

the guy at import spares reckoned $500!!

I got an aftermarket pump off the shelf! Exactly the same as a VL commy pump - same block. 91 bucks. Going slow it would take one person 4-5 hours to replace. To illustrate, once me and my mate knew what we were doing, it took us an hour and a bit, go to whoa, using all hand tools. It's not really as hard as people make it out to be, you just have to accept that there is no quick way to do it, and it's pretty systematic from there. Just make sure you mark the timing belt location on the cams and the crank, and take good note of the slack in the belt, and remember to only make it as tight when you're putting it back together. Otherwise you have to pull the freaking thing right back apart again!

Timing belts are $140 ish, $60 odd for good coolant, so that's $300 odd in parts, and in all reality it should only take a qualified mechanic with all the right tools 2 hours to do the job, but you can bet your life you wont get the job done for $400 anywhere. add that to the fact that they'll probably find "a worn fanbelt" etc, and you'll be up for $600 at least, vs a day getting to know how your engine works.

Meanwhile, my leak has started up again, I pretty sure it was slow enough that it was just evaporating while the motor was still hot. feeling around as best I could, it doesn't seem to be coming from the turbo... sigh.

it'll run off the lines and not appear to come from the turbo if there is a leak up near the washer..

look, all you have up on the passenger side is either coolant feed or coolant return to the turbo.. so if it is definitely in that area, its definitely the turbo or the lines.

sounds like your turbo coolant pipes .. they have copper washers as gaskets, replace them

Yeah thats what i thought before... But now i can actually see coolant underneath and behind the water pump area...

having a leaking problem too. only happens sometimes after a long drive. once i stop turn car off it leaks coolant for about 10mins. but no sign of it missing from the container or the radiator :S not sure if its coming from turbo line, when i floor the car past 4k revs makes a funny screaming sound now. no one can seem to help with it.

Jesus 7 year old thread dig up and youve created a new thread.

The screaming sound is probably the studs on your exhaust manifold check all the nuts are up tight I had the two on on number 6 cylinder loose making that noise.

      Leak from Tokico BM50 Brake Master Cylinder

      By brillo · Posted

      Hi, SteveL Thank you very much for your reply, you seem to be the only person on the net who has come up with a definitive answer for which I am grateful. The "Leak" was more by way of wet bubbles when the pedal was depressed hard by a buddy while trying to gey a decent pedal when bleeding the system having fitted the rebuilt BM50 back in the car, which now makes perfect sense. A bit of a shame having just rebuilt my BM50, I did not touch the proportioning valve side of things, the BM50 was leaking from the primary piston seal and fluid was running down the the Brake booster hence the need to rebuild, I had never noticed any fluid leaking from that hole previously it only started when I refitted it to the car. The brake lines in the photo are "Kunifer" which is a Copper/Nickel alloy brake pipe, but are only the ones I use to bench bleed Master cylinders, they are perfectly legal to use on vehicles here in the UK, however the lines on the car are PVF coated steel. Thanks again for clearing this up for me, a purchase of a new BMC appears to be on the cards, I have been looking at various options in case my BM50 was not repairable and have looked at the HFM BM57 which I understand is manufactured in Australia.

      R33 GTST Steering Rack (49001-19U05) Rebuild?

      By Gantai · Posted

      Well the install is officially done. Filled with fluid and bled it today, but didn't get a chance to take it on a test drive. I'll throw some final pics of the lines and whatnot but you can definitely install a DMAX rack in an R33 with pretty minor mods. I think the only other thing I had to do that isn't documented here is grind a bit of the larger banjo fitting to get it to clear since the banjos are grouped much tighter on the DMAX rack. Also the dust boots from a R33 do not fit either fyi, so if you end up doing this install for whatever reason you'll need to grab those too. One caveat with buying the S15 dust boots however is that the clamps are too small to fit on the R33 inner tie rod since they're much thicker so keep the old clamps around. The boots also twist a bit when adjusting toe but it's not a big deal. No issues or leaks so far, steering feels good and it looks like there's a bit more lock now than I had before. Getting an alignment on Saturday so I'll see how it feels then but seems like it'll be good to go

      Leak from Tokico BM50 Brake Master Cylinder

      By SteveL · Posted

      I don't get in here much anymore but I can help you with this.   The hole is a vent (air relief) for the brake proportioning valve, which is built into the master cylinder.    The bad news is that if brake fluid is leaking from that hole then it's getting past the proportioning valve seals.   The really bad news is that no spare parts are available for the proportioning valve either from Nissan or after market.     It's a bit of a PITA getting the proportioning valve out of the master cylinder body anyway but, fortunately, leaks from that area are rare in my experience. BTW, if those are copper (as such) brake lines you should get rid of them.    Bundy (steel) tube is a far better choice (and legal  in Australia - if that's where you are).
