rippon91 Posted June 27, 2016 Share Posted June 27, 2016 As above there is a considerable amount of vapid that has started coming from the breather on the right hand side of my rocker cover, there is no Pcv valve as it goes into a catch can, what could be the cause of this?

H_D Posted June 27, 2016 Share Posted June 27, 2016 vapour will be more visible in brighter light i.e sunlight... the whole point of the bigger breathers is to help crankcase vapours/gasses escape more efficiently.I highly doubt its your piston rings unless if it actually spitting out oil from the breathers.

rippon91 Posted June 27, 2016 Author Share Posted June 27, 2016 Cheers guys I'll get a compression test done but is it likely to damage it more by using it? Quote Link to post Share on other sites
rippon91 Posted June 27, 2016 Author Share Posted June 27, 2016 Also I've read that it could be from bad grade fuel I.e supermarket fuel that I've just filled it up with, anyone believe this is possible? Quote Link to post Share on other sites
