Hey!

So I've been swapping my head bolts to arp2000 studs all has been going great till I got to the front of the engine. For noting I am doing this with the cams in the engine and want to confirm there isn't some  magical trick to do this without removing the cams.

Basically at the front of the engine the gap between the cams and the head is too small to fit a 5/8inch socket. The old head Bolt removed fine, the new stud went in fine, washer and nut all fine. Just can't get the socket in. Just wondering if anyone has any hints or tips, or if I just need to bite the bullet and remove the cam?

Cheers for the help

Toby

Damn thing, need to make another, needed it for the four corners. Got all 4 to 60ft pound, them on the final 90ft pound torque it snapped on the second one. So need to make another for the final 2 bolts

I had the same issue, but couldn't get to any of the nuts. Ground the crap out of the socket, luckily mine didn't break.Then bought a cpl of superslim sparkplug sockets; they only fitted on the middle studs - still wounldn't fit at either end, very tight fit alright...the ground-down socket barely fits and only fits in one position. Thats with tomei cams.

With the standard cams I and no issues using a 3/8inch 5/8th socket as they are pretty slim. And then needed to ground down the socket for the corners... Hopefully I can finish the last two tmrw with just one more socket :)

but pretty happy to have it almost done!!!

if you don't have some cut up twisted, grinded, or bent wrenches and sockets collecting in your shop your car either runs really good or you have a mechanic lol. Most my wrenches end up grinded or bent up in some way along the line to fit just right in wierd places on weird skyline jobs. hope the job goes well mate get that boost cranked up mate.

Got it all done! i have to say i was super worried about snapping a stud or bolt in the days leading up to it, as usually its easy enough to remove and either retap or ignore completely. But with this if anything went wrong it meant taking the head off at a minimum. 

Anyway first two I did i felt like I was undertaking open heart surgery. Torquing the bolts seems unnatural to put so much torque on such a small nut. But after the first two i wasn't worried at all and got into a good little rhythm.

Then i got to the corners, wasnt too worried, came here for help, got some awesome advice, continued the job and got it done with no issues. Overall was a fairly simple job!

Super happy its done though, also really happy i invested in a good quality digital torque wrench last year, really makes a huge difference!

You skip a few heart beats when it makes these creaking noises too haha

I almost had a heart attack with i snapped the shaved down socket on the back of the head....  then i remembered it was more likely to be the dodgy socket i created than the head bolt...  was so relieved when i saw the socket snapped!

I must say, when looking back at it, doing head studs/nuts with the motor still in the car is quite amusing as you're in an awkward position!

Doing it on an engine stand, right next to you feels more natural.

      Baron's R34 GT-R build thread - car in Japan for 5 years -_-

      By BaronOBeefdip · Posted

      Hey, it's a GT-R, it's just as significant a moment as mine😁 It's not ideal when things are uncertain; I'm the type of person that always has a set plan for things in life so being unsure of this plan puts me in a weird place mentally.

      Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?

      Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card style AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had no flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).

      So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?

      Lets play a game - What is causing my oil consumption?

      By tsuokun · Posted

      Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.
