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.

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
