So having a discussion with my dad today and he doesn't think it is the fix to fit a catch can. His reasons are it's just a band aid to the real issue and thinks it is a back pressure issue so I need to clean out all the oil feed pipes he says they cause problems mk2 Jags had them on and they caused nothing but trouble and back pressure through them. I told him I'd rather empty a catch can ecery so often then have to take off the TB and clean it and the inlet manifold on a regular basis. The history of the car is he bought it from vauxhall via mobility when it was 1 year old and had it until 74k miles ish then it was stood 2 years and I bought it from him and started getting the oil issues (valve stem seals do need changing because of it being stood). What are you guys thoughts? And is there any technical data as to the pros and cons?
