my pistons are all marked up as L A, L B, R A, R B but iv forgoten which gose where, looking at the front of the engine (i.e at the oil pump) which piston gose where cus i think i might be trying to putr the wrong opiston on a rod because im having major truble geting the damn pins in.

cheers

 

Are these your own markings your referring to?

If they're the subaru markings then it should be like below:

On top of the engine there should be a marking, hmm how can i explain, Down the centre line of the 2 block halves approx in the middle there should be markings showing which goes where.....

I have these on a EJ25 but not sure about a EJ20 though.

Hope that helps.

If they're your own markings then maybe one of the pros could advise.

Good Luck

 

A + B refers to the size of piston there are two grades, you should have marked them....

FYI i found it easy to get the pins in by heating the pistons with a hot air gun once in the bore. The slight expansion lets the pins slide in like butter. lol.

 

no their marked on the rim of the piston face them selves.like a stamping or suming.

cheers

 

good idea i just might try that!lol.

 

Here you go
