Hi guys, I want to change my cam and springs today.
I was planning on using some extension cord shoved into the spark plug hole and then taking the springs out etc.

I was just wondering, how do I know when the piston is at the top?
at TDC piston 1 and 6 are at the top, but what about the other 4 cylinders?

Or does anybody know where you can buy one of those spark plug / air compressor adaptors from in perth?

just take the plugs out and shine a torch in the hole and you will see the piston if its at the top.

just make sure its on compression stroke, should be easy to tell with the rocker cover off.

the pistons will work in 3rd i think.

eg 1&6 and TDC 3&4? will be at BDC and 2&5 will be half way.

Someone may have one you can borrow locally? firing order for the i6 is 153624 i think, which would mean at 120 degrees from top dead centre when turned in the right direction, cylinders 5 and 2 would be at top, and another 120 degrees would bring 3 and 4 to the top.

a local machine\engineering shop can turn it up,supply aplug and a tail fitting for the hosefitting,or modify a spark plug.

Thanks guys, hehehe never thought of using a torch :oops:

I was thinking it worked in thirds, but is it necessary for it to be on the compression stroke because I'm not planning on using compressed air?

Was just gonna jam as much extension cable into the cylinders as possible then 'hopefully' the valves wont drop into the cylinders. Although the valves wont fall all the way in will they (if a mistake is made)?

if the stem seals are ok the valves will stop there,a pickle fork will compress the springs to get collets out,then replace the springs and reassemble,you may have to push the valve up higher to get collets in the grooves and lock,lifting throuh the plug hole.
