Hi all,

Just wondering if neone could tell me what this is or what they think it is. Basically i can only here it at idle and very low in the rev range as its not that loud just irratating (Spelling). Its coming from the engine bay and sounds to me like a leaking exaust manifold but it did it before i got my extractors and now it still does it with the new ones and new gasket, i changed the oil and its still there? someone once told me that its normal for Double Over Head Cam engines to do this but i disagree, the car still runs fine and isnt lacking in power its just really starting to annoy me.

Ne Help Much Appreciated.

Cheers

John

In my old 202 it was the hydraulic lifters, and my GTS-T makes this same sound. I was told cheap oils can make your car do this, but I have been running fully synthetic in mine, so Im not too sure whats going on. Anyways, It never hurt my 202 and my 33 is going strong.

could be hydaulic lifters.

I have been told that Mazda's have a bad problem with this, and they have a special oil additive to fix it.

Put it in with the oil run for 20mins until noise is gone, then drain oil. Apparently it (oil) comes out black, thick and lumpy. Basically the additive is an internal engine cleaner.

Ask your friendly Mazda dealer about some

"yeah i always get bad fumes in the cabin if sitting in traffic for a while. gives me a saw throat after extended preiods, im assuming its not real good for you."

N/A_R33,

mate you have an exhaust leak, go to an exhaust specialist and have it checked out...they will find where it is...

i had the same problem with a previous car, after changing the exhaust manifold gasket many times and not fixing the problem, i discovered that the manifold face was warped and not sealing properly...

had the manifold machined and problem fixed!

Cheers

i had it checkd and it seems one of the 'rear' bolts for the exhaust manifold is missing, sposedly this is a common problem in 33 gtsts and 95% of the time people dont bother replacing them as its a huge job, i can definitely hear the clicking of the air leaking but as far as power/econoy nothing seems to be affected, two different tuning shops told e not to worry about it unless it starts to get worse, any suggestions ? anyone know how much it usually costs to get the bolt fixed ?

I got mine engine tap tap tap last month when cold start, noise gone when warm.

On way back from GOR cruise, my car misfiring ratatatata hard on 3rd gear acceleration. The next morning oil pressure running low, car has flat spot everywhere but that cold start tap tap tap noise totally gone....... what the?????????

Car is slowly getting better and better to drive, but still a bit flat spot and won't make boost on 1st gear (gauge only goes to 0). Now boost only comes in 2nd gear or higher (gauge goes to a bit over the halfway mark between 0 & +7).

On cold start, oil pressure will go past 6 mark on +/-1200rpm idle. When warm, on 700rpm idle oil pressure is a little less than 2. When driving around 2500-3000rpm oil pressure is about 4, and cruising 4th gear 60kph about 2000-2500rpm the oil pressure drops to about 3 or 3.5 mark.

Strange..... very strange......

      Hey Dave, welcome aboard! Good to see another soon-to-be Stagea owner here. The wagons are awesome — plenty of space, still got that Skyline DNA, and loads of potential if you’re into mods. Definitely post up pics when you get it, everyone here loves seeing new builds. What model/year are you looking at?

      See if you can thermal epoxy a heatsink or two onto it?

      The other problem was one of those "oh shit we are going to die moments". Basically the high spec Q50s have a full electric steering rack, and the povo ones had a regular hydraulic rack with an electric pump.  So couple of laps into session 5 as I came into turn 2 (big run off now, happily), the dash turned into a christmas tree and the steering became super heavy and I went well off. I assumed it was a tyre failure so limped to the pits, but everything was OK. But....the master warning light was still on so I checked the DTCs and saw – C13E6 “Heat Protection”. Yes, that bloody steering rack computer sitting where the oil cooler should be has its own sensors and error logic, and decided I was using the steering wheel too much. I really appreciated the helpful information in the manual (my bold) POSSIBLE CAUSE • Continuing the overloading steering (Sports driving in the circuit etc,) “DATA MONITOR” >> “C/M TEMPERATURE”. The rise of steering force motor internal temperature caused the protection function to operate. This is not a system malfunction. INSPECTION END So, basically the electric motor in the steering rack got to 150c, and it decided to shut down without warning for my safety. Didn't feel safe. Short term I'll see if I can duct some air to that motor (the engine bay is sealed pretty tight). Long term, depending on how often this happens, I'll look into swapping the povo spec electric/hydraulic rack in. While the rack should be fine the power supply to the pump will be a pain and might be best to deal with it when I add a PDM.

      And finally, 2 problems I really need to sort.  Firstly as Matt said the auto trans is not happy as it gets hot - I couldn't log the temps but the gauge showed 90o. On the first day I took it out back in Feb, because the coolant was getting hot I never got to any auto trans issues; but on this day by late session 3 and then really clearly in 4 and 5 as it got hotter it just would not shift up. You can hear the issue really clearly at 12:55 and 16:20 on the vid. So the good news is, literally this week Ecutek finally released tuning for the jatco 7 speed. I'll have a chat to Racebox and see what they can do electrically to keep it cooler and to get the gears, if anything. That will likely take some R&D and can only really happen on track as it never gets even warm with road use. I've also picked up some eye wateringly expensive Redline D6 ATF to try, it had the highest viscosity I could find at 100o so we will see if that helps (just waiting for some oil pan gaskets so I can change it properly). If neither of those work I need to remove the coolant/trans interwarmer and the radiator cooler and go to an external cooler....somewhere.....(goodbye washer reservoir?), and if that fails give up on this mad idea and wait for Nissan to release the manual 400R

      So, what else.... Power. I don't know what it is making because I haven't done a post tune dyno run yet; I will when I get a chance. It was 240rwkw dead stock. Conclusion from the day....it does not need a single kw more until I sort some other stuff. It comes on so hard that I could hear the twin N1 turbos on the R32 crying, and I just can't use what it has around a tight track with the current setup. Brakes. They are perfect. Hit them hard all day and they never felt like having an issue; you can see in the video we were making ground on much lighter cars on better tyres under brakes. They are standard (red sport) calipers, standard size discs in DBA5000 2 piece, Winmax pads and Motul RBF600 fluid, all from Matty at Racebrakes Sydney. Keeping in mind the car is more powerful than my R32 and weighs 1780, he clearly knows his shit. Suspension. This is one of the first areas I need to change. It has electronically controlled dampers from factory, but everything is just way too soft for track work even on the hardest setting (it is nice when hustling on country roads though). In particular it rolls into oversteer mid corner and pitches too much under hard braking so it becomes unstable eg in the turn 1 kink I need to brake early, turn through the kink then brake again so I don't pirouette like an AE86. I need to get some decent shocks with matched springs and sway bars ASAP, even if it is just a v1 setup until I work out a proper race/rally setup later. Tyres. I am running Yoko A052 in 235/45/18 all round, because that was what I could get in approximately the right height on wheels I had in the shed (Rays/Nismo 18x8 off the old Leaf actually!). As track tyres they are pretty poor; I note GTSBoy recently posted a porker comparo video including them where they were about the same as AD09.....that is nothing like a top line track tyre. I'll start getting that sorted but realistically I should get proper sized wheels first (likely 9.5 +38 front and 11 +55 at the rear, so a custom order, and I can't rotate them like the R32), then work out what the best tyre option is. BTW on that, Targa Tas had gone to road tyres instead of semi slicks now so that is a whole other world of choices to sort. Diff. This is the other thing that urgently needs to be addressed. It left massive 1s out of the fish hook all day, even when I was trying not too (you can also hear it reving on the video, and see the RPM rising too fast compared to speed in the data). It has an open diff that Infiniti optimistically called a B-LSD for "Brake Limited Slip Diff". It does good straight line standing start 11s but it is woeful on the track. Nismo seem to make a 2 way for it.
