Whoa! So what are you saying? Should one buy new/higher strength bolts or what?

Nah, they are plenty strong enough.

The problem is that I have a knack for snapping bolts... that and the fact that the driver's side cam cover is down so that it basically sits flush (from factory) whereas when I was doing up the passenger side one, I figured it should end up sitting flush as well.

Didn't think that they may be two different seals, thus I kept tightening :domokun:

Success!

Finally replaced the seal. Easy enough when you have the right uni joints. Hopefully the rear is seated in the groove properly but looks like it. And no left over bolts too - always good.

I did notice cyl 6's spark plug well had lots of oil in it. Is this an issue? I just need to syringe it out and change the plugs as I did in my 300. That and apart from being a bit stiff, the old cam cover seal had no obvious point of leakage..

Turbo, modified actuator and 3" dump should be arriving soon then it's hopefully back on the road after a quick service!

Lol plenum already back on. Could do it with it on though I erection.

Plug code?

I always get an erection when I work on my car too. :blush:

LOL.

The leak is the seal around the rear plug tube. The seal cant be replaced (New rocker cover is $220us) and would have been the cause of your oil dripping onto the turbo. Syringe the oil out and change the plugs, it will take years to fill the hole again.

DAMNIT!

So I replaced the cam cover seal for nothing?!?!!?

There is only about 5-8mm worth of oil in the well, does it leak down from the top where it seals onto the cam cover?

Ah well at least I know the seal won't fail on me now

Cheers for the spark plug code :)

Oh ok, mine was full to the brim and running down the cam cover dripping onto the turbo. It was also leaking out of the gasket as it was brittle. If its only a small leak dont worry too much, my car ran fine like that for months.

Perhaps you can clean the tube well and squeeze some gasket sealant between the rubber and the metal tube? Don't force it, I put a screwdriver straight through the rubber, and don't get any inside the engine if you can help it.

:cheers:

Ah well,

May still have been the seal, it was quite brittle and stiff but there was no area that screamed "look at me I'm leaking!". It was deifnately leaking from near cyl 6 though as that's where all the buildup was that was dripping onto the turbo.

I just want it to drive again, I'm too impatient when it's my daily that is being worked on :(

  • 2 weeks later...

So yesterday Jetwreck and I installed the following:

- Custom dump pipe (thanks Scotty)

- Preloaded actuator (thanks again Scotty)

- high flowed Hypergear turbo

- Standard BOV (removed Blitz item)

- New sparkplugs.

- LHS cam cover seal (did a few days ago)

And we have boost! A little over 1 bar. Comes on strong in the midrange, and was a bit laggy, coming on about 3000rpm but I discovered I had a few vacuum leaks so hopefully that'll clear it up. That and the ECU needs to relearn everything again..

The bad news - an oil leak from the oil feed on the turbo... We had to grind the housing down on the oil feed to be able to fit the banjo supplied by Hypergear. That and I suspect the copper washers we used were slightly too big meant we had one mother of a leak. So out it came and it's now on holiday in Sydney with Jetwreck getting machined properly and a new banjo with correct washers fitted.

The good news - from the 5min drive I did have it felt pretty strong, especially in the midrange. Cnsidering it's about $400 cheaper than the precision turbo rebuild I'd consider it a good option. That being said, if I had my time again id firstly pull the engine and go for a precision turbo rebuild, for ease of installation.

Anyway, another week and a half or so and it'll be back on the road

Big thanks to Jetwreck, massive effort so far...

Sean

Coming onto boost at 3000rpm isn't too bad is it?

I think that's when mine kicks in...

I don't mind having a bit of "lag" so I can baby the car in the morning and be able to driving at around 2500rpm

lol im already at about 7-8psi at 2500

I can handle 3000rpm, a bit more town friendly that way too.

Was very slow to rev up even when not under load so I imagine those vac leaks were killing it.

At least we know it works (minus leaks)

what turbo did you go for?

lol your not serious.

running close to 300 without a boost gauge.. it was the first thing i did lol

yeahyeah I know...

well the Profec displays boost in real time...so I'll use that once its hooked up...hopefully this Saturday!

    • I would just put EBC back on the "I would not use their stuff" pile and move on.
    • Can I suggest you try EBC directly again and link them to as many competitor catalogues as you can to show their listing is incorrect, eg https://dba.com.au/product/front-4000-series-hd-brake-rotor-dba42304/ If you have access to an R33 GTST VIN and your VIN, you could also use a Nissan Parts lookup like Amayama to show them the part number is different between 33 GTST and 34 GTT which may get their attention
    • So i got reply from EBC and they just this site where you can clearly see those 296mm fronts on R34 GTT. I send them photos and "quotes" that 296mm are not for 34 GTT and they are too small. But it will be very hard to return them cuz nobody here knows 100% and they just copy those EBC catalogue :-D https://ebcbrakesdirect.com/automotive/nissan/skyline-r34
    • Hi, is the HKS  Tower Bar still available ? negotiable ? 🤔
    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
