Planning to reseal my rocker covers in the next few weeks. Was looking into something like this http://www.ebay.com.au/itm/Nissan-240SX-SR20DET-Stainless-Valve-Cover-Bolt-Kit-/380347803159?pt=Motors_Car_Truck_Parts_Accessories&hash=item588e7ee617 but for an rb engine. Anyone know where i can get one from? Also is it worth while? as i always have the tendancy to rounding the top of the phillip screw. Any other suggestion?

I got replacements from bunnings, m6 x 25 high tensile hex bolts.

Then I just used a washer on either side if the rubber grommets so it didn't pinch through. Looks pretty good on all up cost me about 10bux.

And Munky is right, don't tighten the shit out of them just do them up enough to squash the rubber a little and then redo after a few heat cycles.

Edit: also don't forget to run a little bit of gasket goo around the back of the cover where the half moons are, they have a tendency to sometimes leak.

You can put a thin layer of gasket sealer on the whole thing. Doesn't matter about the torque, just tighten it until it is tight. It's a 6mm bolt holding on a cover, not a 27mm bolt holding your harmonic balancer on.

No need for sealer on the whole gasket, it just makes more work the next time you remove them.

Some sealant smeared inside the half moons, on top of the half moons, in the corners of the front cam caps and on the lower edge at the rear of the exhaust cam cover and it will be fine.

Just put a blob on your finger and push the blob into the corner where the cam cap meets the head. Dont worry about smoothing it out as the gasket will move it around and make sure the corner seals up nicely

They are normally ok unless thay are solid as a rock

And getting back to the original post.... if your rounding the phillips bit ou your using the wrong size screw driver. You need a huge ass mother of a phillips head to do the job properly. Once you have the right size screw driver you will see thats its actually quite hard to damage the top of the screw

I would replace the half moons! I decided not to the first time and I had open it all up a 2nd time because it still was leaking out the back.

I'm pretty sure the link you first posted is for a coilpack cover and not a rocker cover.

A trader on here 'Kudos Motorsport' sell genuine Nissan Spares and they have all brand new bolts and grommets. They will set you back about $95 and I have found Kudos to be pretty cheap to be honest.

      Cheers. Skyline is back on the menu, can’t get rid of it. It’s like a child you don’t want, or herpes

      I got back to Japan in January and was keen to get back on track as quickly as possible. Europe is god-awful for track accessibility (by comparison), so I picked up a first-gen GT86 in December just to have something I could jump into right away. The Skyline came over in a container this time and landed in early January. It was a bit battered after Europe, though—I refused to do anything beyond essential upkeep while it was over there. The clutch master cylinder gave out, and so did the power steering. I didn’t even bother changing the oil; it was the same stuff that went in just before I left Japan the first time. Naughty. Power steering parts would’ve cost double with shipping and taxes, so knowing I’d be heading back to Japan, I just postponed it and powered through the arm workout. It took a solid three months to get the car back on the road. Registration was a nightmare this time around. There were a bunch of BS fees to navigate, and sourcing parts was a headache. I needed stock seats for shaken, mistakenly blew 34k JPY on some ENR34 seats—which, of course, didn’t fit—then ended up having the car’s technical sheet amended to register it as a two-seater with the Brides. Then there’s the GT86. Amazing car. Does everything I want it to do. Parts are cheap, easy to find, and I don’t care what anyone says—it’s super rewarding to drive. I’ve done a few basic mods: diff ratio, coilovers, discs, pads, seat, etc. It already had a new exhaust manifold and the 180kph limiter removed, so I assume it’s running some kind of map. I’ve just been thrashing it at the track non-stop—mostly Fuji Speedway now, since I need something with higher speed after all that autobahn time. The wheels on the R34 always pissed me off—too big, and it was a nightmare getting tires to fit properly under the arches. So I threw in the towel and bought something that fits better. Looks way cleaner too (at least to me)—less hotboy, less attention-seeking. Still an R34, though. Now for future plans. There are a few things still outstanding with the car. First up, the rear subframe needs an overhaul—that’s priority one. Next, I need to figure out an engine rebuild plan. No timeline yet, but I want to keep it economical—not cutting corners, just not throwing tens of thousands at a mechanic I can barely communicate with. And finally, paint. Plus a bit of tidying up here and there.

      Nope, needed to clearance under the bar a little with a heat gun, a 1/2" extension as the "clearancer", and big hammer, I was aware of this from the onset, they fit a 2.0 with this intake no problems, but, the 2.5 is around 15mm taller than a 2.0, so "clearancing" was required  It "just" touched when test fitting, now, I have about 10mm of clearance  You cannot see where it was done, and so far, there's no contact when giving it the beans Happy days

      It's been a while since I've updated this thread. The last year (and some) has been very hectic. In the second-half of 2024 I took the R34 on a trip through Germany, Italy, France and Switzerland - it was f*cking great. I got a little annoyed with the attention the car was getting around Europe and really didn't drive it that much. I could barely work on the car since I was living in an inner-city apartment (with underground parking). During the trip, the car lost power steering in France - split hose - and I ended up driving around 4,000kms with no power steering.  There were a few Nurburgring trips here and there, but in total the R34 amassed just shy of 7,000kms on European roads. Long story short, I broke up with the reason I was transferred to Europe for and requested to be moved back to Japan. The E90, loved it. It was a sunk cost of around EUR 10,000 and I sold it to a friend for EUR 1,500 just to get rid of it quickly. Trust me, moving countries f*cking sucks and I could not be bothered to be as methodical as I was the first time around.
