i know it can be done without and hassle, its just getting the right tool that seems to be the problem.

i've got the cams out and the valve spring/retainers exposed. the tool i need is in america, and im extremely weary about sending my money to someone i cant find if they tried to screw me.

the tool i need is similar to this: http://www.autobarn.net/xxxw-sp-91400.html

and ive got no idea on where to get one in australia.

can anyone help me out?

They used to do one at a time it with a modified spark plug and an air compressor. Bore out the spark plug and braze in an air hose fitting. Attach the hose and away you go, 70-150 psi [depending on your comp size]. Not sure how you'd do it on a skyline, but on motorbikes you'd make up a tool that bolted to the camshaft journal/split mount holes and compress the springs, similar to the bucket and shim adjustment tool. The valves would stay closed from the air compressor.

I've seen the home made tooling, I've never seen it done.

You can buy the right tools anywhere. The problem is finding one that can be used on nissan OHC cylinder heads without fouling on the cam journals etc. Its fairly tight to work around, Ive adapted several tools to suit. Go buy one from a decent toolsupplier and make it work.

Thank sky30 his pic. :)

Keen to see how it goes.. I wish I didn't have to rip my head off to sort the oiling issues (restrictors).

ill keep this thread posted, with pics.

I assume you are using compressed air to keep the valves closed/up????

yeah ive bought a connector off ebay that screws into the spark plug hole. then the hose connection for the compressor screws into that, then the compressor hose onto that. it should be sweet.

i've also heard of another method called the indian rope method:

what you do is get around 170cm of plastic/nylon rope. shove it into the bores through the spark plug hole while at bottom dead centre, keeping some rope hanging out, then rotate the motor close to top dead centre when you start to feel the motor get a bit tight to turn. apparently its common practice in alot of places. although air pressure sounds like a safer option to me!

Yes, no messy fibres or dust. Thinking as I go here, you could use something like 4mm plastic hose though, the kind they use for drip lines in gardens etc. Not as messy then??

But I'd go compressed air still.

i cleaned up the valve spring compressor i made a bit, i made a T piece out of some scrap metal i had laying around and got it welded at my exhaust place for $5.

im happy with it now. it works well. as soon as the fittings for the compressor get here ill be doing them straight away.

here are some pics for anyone who wants to make one themselves:

I'll borrow one of my old mans sidchrome long reach sockets. :)

lol.. When I was a young lad I chopped up and bent a heap of his sidchrome spanners as I had trouble removing a few bolts. I wasn't allowed in the shed for quite some time. :S

BAHHAHAHAHAH thats gold

im still not allowed in my old mans shed :huh:

time for an update.

i did 4 of them today, ill do the other 20 tomorrow. getting the collects to go in where you want them to is an ugly job at first, but you get the hand of it. the first 2 went in after 20mins of stuffing around then the last 2 went in straight away after figuring it out. you've pretty much got to move the retainer so the valve comes up dead centre between the collects, let one of them drop into place, then hold the other one tight and push the valve spring compressor all the way down till its got space to move in.

its alot easier than it sounds.

bugger that for a joke. Good that it works but how did you go about pressure testing the system?

Not too bad if you do the job for your own vehicle but it sucks now because I've had three people ask me to change their valve springs and seals over without removing the head. What's your email so I can send 'em your way lol.

    • Next, remove the upper and lower radiator hoses, both are held with a spring clamp. While you are under there, tackle the Auto Trans cooler lines.  Again both are held on with spring clamps, and as mentioned above you should cap them on the radiator side with an 8mm cap, and on the car side loop them with a length of 8mm pipe - this will stop you losing a dangerous amount of AT fluid during the rest of the job If you've been meaning to add a sender for AT trans temp, this is a great time to do it; put a sender fitting into the passenger side line as that is the inlet to the cooler/radiator.
    • Next you need to remove the intake duct (as with pretty much every job on these cars), it is a series of clips you gently remove with a flat bladed screwdriver. They do get brittle with time and can break, and I have not found a decent quality aftermarket one that fits (they are all too soft or flimsy and don't last either) but the nissan ones are a couple of bucks each (ouch).  Once the clips are off (either 8 or 10, I didn't check) you lift the intake duct out and will see the reservoirs Undo the line into the radiator side cap (some bent needle nosed piers are awesome for spring clamps) and then remove the 4x 10m nuts that hold both in place.  I didn't get these pics, but remove the line under the radiator reservoir (spring clamp again) then remove that reservoir. Then you can get at the intake reservoir, same thing, spring clamp underneath then remove it. BTW This is a great time to put in a larger (+70%) combined reservoir that AMS makes..... https://www.amsperformance.com/product/q50-q60-red-alpha-coolant-expansion-tank/ They also make an Infiniti branded and part# version if that is your thing
    • To drain the Intake Heat Exchanger, there is a crappy drain plug in front of the driver's side front tyre: You should use the largest headed phillips screwdriver you had, and in my case I needed vice grips on the hose above as the plug was tight (tighter than it needed to be, since it has an o-ring seal).  After you have a tray down and open the drain, open the intake heat exchanger reservoir cap (drivers side one) and you should get a couple of litres of coolant To get to the radiator, you need to remove the plastic engine undertray. It is held on with a series of 10mm headed bolts and some clips. For the radiator, there is another type of crappy drain (kind of like a plastic banjo bolt) and you should attach a length of hose to direct the stream of coolant per this pic (otherwise the coolant hits the rad support and goes everywhere). The drain is on the rear of the radiator on the driver's side and a bit hard to find. Put a big tray or bucket down (5l won't be enough) and slowly unscrew the fitting by hand. You only want to remove it far enough for coolant to flow, it you unscrew it right out the whole fitting and direction pipe will come off and you will get a coolant bath (yum!). Undo the radiator reservoir cap and it should empty about 8l
    • So, this shouldn't be such a mission, but there were a few tricks so I thought I'd post up a DIY for it. This was on a Q50 Red Sport but I doubt any other V37 model is very different (maybe just less steps for the intake heat exchanger hoses) I pulled the radiator out to flush it because the car was running hot at the track, but obviously the same steps apply for changing a radiator for any reason including an upgrade. If you are removing the radiator, you of course need to drain and refill, so have 5+ litres of blue coolant ready. You also need to drain the intake heat exchanger to remove the radiator so you will need a couple of litres for that as well. You will also need something to deal with the auto transmission lines, I used 2x 8mm rubber caps on the radiator side, and a short length of 8mm pipe on the car side.....unless you can block these lines quickly you will loose AT fluid and it may be enough to hurt the transmission if you don't refill it. 2 other tools that really help dealing with coolant lines and spring clamps are Bent Needle Nose pliers Hose pliers Between them they will reduce the frustration (and injury) potential by about 1000% Other than that....lets go... "First, jack up your car". Yes really, and put it safely on stands. If you are not confident doing that you need to give this job to a mechanic
    • If the forester is anything like our old 2007 GTB Liberty, I could near on run ling Long's and "rate them", as no matter what, it just hung to the road, even when abusing it in a hard launch in the wet, or throwing it at corners.
