Leaky Manifold To Head! Help!

Hey guys,

I recently had a 3inch dump pipe and highflow cat installed by an exhaust workshop to complete the turboback on my series 2 r33 gts25t.

The job was quick but the exhaust shop found a slight leak from the exhaust manifold to the cylinder head. They said it wasnt a huge problem but I will need to fix it sooner or later.

He mentioned that the gasket would need to be replaced and the job would cost roughly $600 to $700.

I have searched the forums and the workshop is definately right.

The ticking sound from the leak is only noticable from a cold start and goes away once the car heats up (mechanic said once the car heats up it expands and partially closes the hole)

I have a few questions:

1) I want to replace all the gaskets (and studs) that are "on the way". Would this just be the gasket and studs from the manifold to the head?

2) Would I save some money if I get this done while getting my major service done? (I am planning on doing my major service soon...timing belt, water pump)

3) Would I be able to get the gasket and studs from Nissan?

Quick details on the car:

1997 R33 Series 2 GTS25t

Stock as rock (besides a turboback exhaust and pod filter)

Any help would be appreciated!!

Yes nissan will hve all the parts needed or get permaseal from burson's.

It is a pretty big job to do the manifold gasket.

If u are planning on doing a turbo upgrade i would wait until then because they have to pull the turbo right off anyway. Even a couple months etc, it wont hurt anything having the slight leak.

If you are handy with your tools then its cheap enough to do it yourself. But you will have to take your turbo off as mentioned above. The genuine studs from Nissan are the best way to go or ARP make stronger ones for a price. You will need to get the manifold machined flat so that it can get a good seal with the new gasket. Make sure that cost from the exhaust shop includes the machining of the manifold. You can replace the gasket without machining the manifold but there is always a greater chance it will leak again over time. Do it once do it right :)

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
