Thanks pomeo, yes it's a struggle but i hope at the end it'll be worth it. Anyway i was thinking, if i need to replace these fabled seals there may be an easy way. i.e lift the liners up just enough so they don't come past the rings and then stretch the seals over and down or press out the wrist pin,
I wouldn't, have you got a piston ring compressor or have you put the sump back on?
no chris, the sump is on and i need to replace the seals from above i.e either squeeze them down over the liners or take pistons off via wrist pins and then replace seals. or failing that take liners off pistons/rings replace seals and then slide liners back over pistons/rings. i mean i've done it with four cylinder motorcycle engines so how can it be harder with one liner?
I just got the o rings today, pulled a liner up, made a hook gadget and pulled an old o ring out, i see why you should replace them now!
it snapped so easily. I reckon i can slide the new ones down over the liners and into position with some rubber/nylon lube(not ky) I think maybe i made a lot of fuss over nothing.
well, good news at last, today i put humpty dumpty back together and started her up, sweet! only misfiring on 1 and three (according to my diagnostic plug thingy) i suppose i'll never know really what caused the clatter but i think maybe tappets. as a last resort i cooked them in the oven at regulo 90 basted in uniparts finest 10/40. my house smells like a greek tanker out of athens. thanks for everyones input. i hope this thread helps others.
