Question - getting the head off? um my 13mm impact socket just slips on it its a double hex so i didn't try again do i need a special socket to get the head off?
Question - getting the cam out? nisman a while ago said take the rocker cover off and rocker gear out i got all that out but the cam doesn't really wanna "slide out" do i need to pursuade it and which way does it slide towards timing gear side or towards thermostate side?
btw engines not in the car im stripping it down for a rebuild so all help appreciated.
Question - whats the biggest the standard cam can be reground to?

Now that you have probably stripped the heads of the head-bolts, you need a 12 sided (double hex) "12mm" socket for an E15 engine.
The standard setup can also have braces from the inlet manifold to the block as well as a bracket behind timing cover (on outside) and 2 heater/oil cooler hoses form manifold to - you guessed it - oil cooler.
To remove the cam, after removing rocker assembly, remove 4 x 10mm hex bolts from cam seal/retainer plate at front of engine - remove plate and carefully slide cam out through front of engine.
As far as cam grinds go, you could try phoning Camtech (Sydney), (02) 9755 3101 - they did a regrind for me a couple of years ago for about $80 - can't remember price for billet grind. If you wan't to run a Big cam you'll probably need descent valve springs aswell.
What are you planning?

nah i haven't stripped it, i realise if a socket slips once to stop, i was talking to someone and they said it may be a torx socket?
i removed those 4 x 10mm bolts and the cam didn't wanna slide out, how do you get the plate off?
plans are to hit 11s...

oh and when you say a double hex 12 for an e15 engine are you implying that nissan makes a special head socket? cause my 12mm double hex 3/8" didn't fit, yet my 13mm single hex 1/2" did...

There must be too much shit around the bolt heads if you cant get a 12mm socket on, from what I've seen, all E13, E15, engines are 12mm double Hex head bolts.
Like the standard style.

i'll try cleaning em up with a bit of throttle body cleaner tomorow to get all the shit off em, but looks like who ever had the engine before me did a makeshift rebuild, on the dump bolts were 12, 13, and 14 as apose to all 13's i found majority of the bolts on and around the engine to be 13's is this same with your expierence or always 12s?

the head studs are a standard socket, they are double hex, as are the grooves in a standard 12mm socket or ring spanner.
if the socket didnt fit, try cleaning the bolt head, they should.
otherwise a previous engine reco may have resulted in after market replacement head studs, which isnt an uncommon thing.
once you have taken the rocker gear off, you will need to remove the timing belt, top pulley and the cam retainer plate.
first turn the motor to top dead centre, this is when the slot in the crank pulley lines up with the 0 on the timing plate. (if the motor is getting pulled apart dont worry about this)
take the plastic shields off
remove the timing belt by loosening the bolt on the tensioner pulley then putting a flat head screwdriver in the slot and twisting the pulley.
once the belt is off, take off the top pulley by undoing the 3 bolts.
then undo the 4 bolts on the retainer plate.
once this is all done the cam should pop out. I find the best way is to remove the dizzy and push the other end of the cam with your finger.
it comes out over the drivers side of the motor.
dont worry about having to time the dizzy back up when you want it in again because it has an offset locater and will only go in one way.
make sure when you put the rocker gear back on, you put the side to the head that has the oil galleries, otherwise the valve tops will not be lubricated.
almost every bolt i touched were 12's, 13 is more old school(1/2 inch)
the cam i had was stage 3, although he said it wasnt possible, he still managed, there was still enough meat left on the under side of the lobe to get a bit more lift out of it, however i thought that stage 3 was more than enough.
if you plan 11's you would wanna take on a 2nd and 3rd job!
