UglierBoss Posted August 3, 2023 Share Posted August 3, 2023 Hi all, long time no speak. I am reconditioning a second hand YBR engine and it does run. I suspect something isnt right with either the piston or the valves as its a bit tappy. I have taken the head apart and the valve springs are slightly different, but in the Haynes manual and the workshop manual they are supposed to be the same length. can anybody knowledgeable tell me which way round the valve springs go. one is slightly longer by about 5mm, and the other is slightly fatter by about 2 or 3mm. or perhaps I should just get new springs? Any help greatfully appreciated. Quote Link to comment Share on other sites More sharing options...
Moderator Snakebite68 Posted August 3, 2023 Moderator Share Posted August 3, 2023 Considering the usual sort of price for these things, since you already have the engine apart, I'd personally just buy a new set and chuck them in... Quote Link to comment Share on other sites More sharing options...

Double check valve timing too, been there done that Quote Link to comment Share on other sites More sharing options...
