Oil catch can?

Hi I have a couple of old diesels that hardly get used some days less than a mile a day but always pass mot and one has snow tires so useful at times, but it seems to have a lot of oil in the inter cooler etc so was wondering if it is worth trying a catch can seem to have good reviews but vary an awful lot in price. Anybody fitted one. can recommend it?

Why don't you try a simple version! Use a licozade bottle it's some wire wool in it. If you see an improvement then invest in a catch can

It's not something I've heard of in the F, or any K series to that matter.
