I am embaresed to ask this cos I done it so many times, Problem is the last time I did it was 5 years ago and ive forgot.

Is it every 90 degrees for the gap?? I really cant remember

 

I dont know about it having to be 90 degree just as long as the gaps are NOT all in one line down the piston

 

How exactly do you fit a piston ring? Something I've never done before!

 

You have to gently ease the rings over the pistons, bending too far can distort/snap them.

And with regards to the gaps its usually done by the manufacturers spec, which will be different through out them. General rule of thumb is to keep the gaps are far apart as possible, or at 1/3 intervals.

 

Its every 120 degrees

 

Just bear in mind some manufacturers specify different though

 

The haynes manual says 90 degrees and the CVH tuning book I got says 120 degrees. I went for the 120 degress one as the gaps are as far apart as they can be at that.

 

Thats exactly what im talking about

I believe some cars have the rings 180 degrees out. 120 is the normal

 

120 degrees it what it says in the haynes bag 'o' shit manual, Sound and looks right to me

 

PMSL

 

dont forget the oil control rings and gauze need to be placed a seperate intervals also

 

Well thats what I thought, When I took the pistons out the gap for the top and bottom oil ring was in the same place and the gause was about 45 degrees from them, It was like this on all 4 pistons too

 

Rings do rotate in the bores while the engine is running

 

I know but whats the chance of both the oil rings on all 4 pistons being in exactly the same place??

 

Quite good apparently
