Gtr Plenum Removal

I have an air leak at the rear of the plenum. Hard to say at this stage where exactly it is but it is definately audible using a little piece of tube shoved down there. At this stage I am thinking one of the gaskets on the rear throttle body or intake manifold has blown out. Anyway seeing as I have some time off over Xmas I was going to tackle this problem myself, I have the trusty R32 GTR workshop manual here and although on paper it doesn't look that difficult upon serious inspection I am a bit bothered by the lack of access to some of the bolts. Might just bite the bullet and pay someone to do it, I just got scared off by the "allow at least 10-12hrs labour" quote.

Has any one here performed this task? If so is there anything I should look out for, any problems you encountered?

Thanks in advance

Jason

bolts on bottom of plenum are a absolute bitch to get to

but 10-12 hrs DAMN i think that guy just wants some money out of you

my mechanic with the help of the manual had it off in under 3 hrs

but he was swearing and cursing about the lack of access

if you got the tools and patience and a spare weekend i dont see why you couldnt do it yourself

only reason i got my mechanic to do it is i knew it would be a headache and i didnt want a headache

as for problems didnt run into any other than u need a trained monkey to climb in engine bay for you

Good Luck

Sounds like I am in for some "fun" then. . . . . I am tempted just to get the mechanic to do it to save the headache too, but it would probably be more rewarding if I did it myself, and I would much prefer to spend those dollars on a pfc.

Its the bolts under the plenum which are really bothering me. I figure if they are hard to take off they will be even harder to put back on. The oil filter relocation kit isn't helping either. . . . .

I would be tempted to lift the engine to do it.

nah its a ball ache alright ....but i wouldnt knock back the job of doing it myself......just make sure you got 1/4 drive flexible sockets....not a uni joint but the flex head sockets themselves.......and take your oil filter off first otherwise the bolt that holds on the vacumm chamber thingy underneath fall down and bang on the oil fiter

      The best part of my setup is, we only have two sites. Our head office where I'd put every thing has plenty of internet capacity. We're on a 200/200 dedicated fibre. Even better, there's only like 6 people in the office at most, and the other office has 2 people in it (likely 3 soon). The majority of our work is in a custom piece of software, as it is part of the backend of the system we provide to customers. For our arrangement, on prem would be wayyyyy easier, and a VPN tunnel site to site is easy for me to manage. Scaled at many many sites, or quite a few hundred employees it's starts getting a bit different for all people outside the head office. However, everything in the cloud becomes worse for the people who operated previously at the site that held the servers, as now they're at the mercy of their internet, and not GBPS internal network (f**k the idiots who hook a desktop PC up on WiFi or permanently sit at a desk using a laptop and don't go remotely with it).   It really does come down to the business needs and structure as to what is best. For us, 365 is mainly being moved to for office apps, moving email from Google to Exchange, and setting up "Active directory". Otherwise we have a ticketing system with support that runs on our own cloud system, or the sales process sits in a CRM we pay for. My biggest push back for having most of the shit turned off and saying no when people want new shiney things is "that won't meet our security requirements, or efficiency gains, so all you're requesting is money spend to open us up to security issues, or to make our staff less efficient" Which is funny when one of our core values is "To do more, with less"

      Think of it as a fancy iFrame with the auth passed through to PowerBI as you're already authenticated logged into Teams   I'm the complete opposite, I hate everything on Prem, it's slow as shit, you need VPNs to get anything happening, then when you want on-prem DBs to talk to say PowerBI you need to install/setup data gateways to essentially VPN back into your SQL instance. I suppose from my perspective, on-prem sucks, but from an infrastructure perspective, your environment is somewhat air gapped to the web via your firewall(s), etc.   The curse of knowledge, the more you know the more you suffer. Farken philosophical shit.

      Wherever you ask them to. I had one added to the crossover pipe near the BOV as well as the hot and cold sides of the intercooler piping to provide greatest flexibility in measuring temperatures post-turbo. I have the IAT installed in one, and bungs in the other two.
