hey guys.....sooo..today was the day...went to pick up my baby after an awaited time.... she got 249.2rwkw :( BUT!... tuner tells me i have an exaust leak... which i assure you was not there when i took it to em'.. so i bring her home and sure enough on the way home its like driving a tractor...now i have had this once b4 and it was my high mount manifold... but i just jacked the car up and i dont see any holes on the manifold at all.. i noticed that the gaskets for the ext. gate are lookin kinda burnt... so guys can everyone (its within the engine bay) just tell us the more obvious spots for it... could it be turbo to manifold gasket?? if so how can i check without pullin the hole lot out...

any input is awsome... thanks everyone

Same prob for me yrs ago, same spot.

The 4 bolter gasket between the turbo and ex manifold.

Only takes a little to drop out and you have a leak, and it's hard to see all 4 sides properly

Get a genuine Nissan one too if that's the case, not a soft ebay job, cause they are soft...

when the car is dead cold start it and feel around for the leak.

You have about 1 minute before it gets a bit too warm

With a high mount you have the manifold-turbo gasket, manifold-gate and turbo-exhaust.

It'll be a big leak so very easy to find.

soooo shortly after posting i went hunting for the leak.....found it at the manifold to wastegate join.... gasket was blown to shit and back... i have a JJR ext. gate..and man they are the worst design ever... like... you cant even get the bolts done up properly cause they rub agaist the body of the gate...stupid..any way... replaced them with some nice metal gaskets :D:)... took her for a spin... and sure enough.... the tractor returned...both gaskets blew out... so i bring her home and pull off the gate again.. (worst four bolts of the car) chucked in some metal gaskets again from an exaust shop... just finished then...started her up and can feel leaks again :ninja::)... i think the flanges are either warped or there is something on the flanges that leakin it...so ill give her a drive but can almost guarantee that it will blow out again.... junk junk junk....

thanks for the input guys.... champions

Thats the 38mm gate?

The genuine hks is no better. I've forgotten the number of times i had that bastard of a thing off and on and cursed the design. I actually had issues with the outlet though, never the inlet.

Get the faces machined flat and install some studs on the manifold. Get some narrow nuts (12 max, 11 preferably) and a 1/4 inch drive socket set with wobble attachment. I ended up buying a sheet of exhaust gasket maker and made my own as the thing was off so often. I never had leaks. But the head/manifold and gate outlet leaked after every track day....

    • Hi all, Restoring r33 series 1 rb25det. All the heater hoses were on their way out, have replaced them and put it all back together. After testing I noticed a small leak from behind the head on the actual metal water line to the turbo when cars warm. I tried running a longer hose over it but it kept leaking...   I am about to take the (stock) manifold off again😔 to change the water line does any one have any lines they recommend? I was looking at Aeroflow Turbo Oil & Water Line Set but not sure what everyone else recommends. Car is completely stock but want to upgrade turbo eventually. it looks like ill have to disconnect a lot just to replace these lines so if there's anything else recommended to do please let me know. Thank you in advance!
    • From memory, on the R33 GTSt at least, while everyone says "It's not adjustable", I found when I changed clutches in mine, it just needed a small adjustment on the rod length. But be very wary here, as you could end up trying to push the pushrod in the master too far, or blowing out the slave.   Most likely though, if the master/slave isn't bypassing internally or leaking out, then the throw out is the wrong height compared to the fingers on the clutch, so when it moves to disengage the clutch, it isn't 100% disengaged. You can check part of this out too by jacking the car up, having the engine running, put your foot on the clutch and try to engage 1st gear. If it goes in pretty easy (Compared to the ground) and/or the wheels start turning a fair bit and it takes a bit too much brake pedal to bring them back to a stop, this is likely the issue.  I'm not sure if you can adjust the height of the forks etc in these though, it's been that long since I've touched any RB gearbox.
    • That's all good, I thought I was missing some interesting feature! Maybe @PranK can double check if that is something that is meant to be operating or not.
    • I hope that is not something that bad. From what i remember he said that only first gear is "hard" to get in and that he has couple of ideas what to try next but idk 😕  hope it is not gearbox out. I will let you know.
    • If it's not the hydraulics, it is probably gearbox back out. Usually as per @Duncan's post, or otherwise associated with not getting the throwout fork positioned correctly. All the way up to catastrophically bolting shit back together without it being aligned properly and wrecking the clutch/input shaft/flywheel/something else.
