Hey everyone just bought a r33 at the auctions :D it went for verycheap soni couldn't resist

R33 gtr

1998

103xxx ks

No accident history :revs: and bought from a dealer

So these are my main things

Firstly is the motor is ticking alot. The motor revs out fine no missing etc, The dealer said he doesn't no when it was services last and recons the oil

Is too thin for the motor.. It happined to me before so that didn't worry me . I just serviced it today new

Plugs new oil filter (10-40w royal purple) and it's still ticking not so much as before but still there, havnt taken it

For a drive yet just turned it in for 10 or so mins.

Secondly is the bovs. I can't here the schoooosh that it's ment to make but at huger revs I can hear dose. Pulled the front bar off intercooler etc cleaned all the piping and assembled back together and still doing it. What's causing the dose???

Thirdly vibration: I've uploaded a video I hope this help but between say 1200rpm and 1800rpm there is a strong vibration

That travels into the cabin. But after 2k it's fine all the way through I was think engine mount or somthing?

And lastly suspension knock , there is a slight knock some where in the front right if the car, only happind when driving straight and

Turning right, bushing?

If anyone can help but troubled

Cheers everyone :P

you are used to the stock GTsT whipper snipper BOV?

GTR sounds nothing like it,

you like the flutter or you want to stop it?

there is a sound deadener/padding inside the airbox, check this is still there,

is the sound coming from inside the car or from the engine bay?

can you see the engine shaking violently?

have you checked the engine and gearbox mounts,

does it do it with the clutch in?

Ticking could be a noisy lifter; does it sound like a diesel engine at idle but you can't hear it when you rev it?

GTR bov's sound nothing like GTST bov's, but what you're hearing isn't dose.

Checking the mounts this week still does it clutch in or out

And yes sounds like a diesel motor when idle ing can sorta hear it when reved up.

My main concern is the vibration.

It's more inside vibration then out side and only between 1200-1800 rpm it's werid

TBH with the problems you are describing, i would take it straight to a local mechanic who is familiar with GTR's. The sounds you are describing could be anything from injectors to bearing knock, if so every km you drive it is doing more damage.

Sounds like something inside the cabin (door/dash panel, etc.) is hitting its natural frequency which will cause it to resonant. This is usually a result of mechanical looseness. Go over all your interior trims and make sure the bolts/pins are secured properly.

Yeah I agree, sounds more like something in the interior which is virating at that particular rpm. Get someone to move around the inside of the car while you hold it there, and try to isolate exactly where it's coming from.

Everything feels in place and firm ;)

Definatly something from the motor side replacing all mounts tomorrow and will see how it goes

So the bovs and sussy knock is sorted

Anyone have advice for the ticking?

Cheers

Took the words right out of my mouth.

Rather than speculating, and considering you don't know the cars history, get it to a reputable GTR workshop and have them complete a major service and comprehensive checkover.

the ticking will be the injectors or the fact it has solid lifters

you can shove all the chemicals you want in it but your are wasting your time

GTRs naturally have that sound and its just how it is

      Did this end up working? Did you take some pictures?

      And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!

      And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.

      Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before
