I want to ask the community that should I fit a catch can for my new car?
Here is the background. I just bought a new Ford Ranger Wildtrack and really love it. My intention is to keep it for the long term(longer than the 5 years factory warranty). I tested drove both the 3.2L single turbo and 2.0L Biturbo variances and decided to go with the 2.0l, because smoother and quieter ride, more power, modern engine design, better fuel economy, etc.
The main downside regarding the 2.0L engine, during my research, is the potential longevity of it. But it seems it is just some anecdotal evidences from someone’s mate’s distance second cousin, who had a problematic one. Nothing, that I could find out, is pointing to a common/systmetic fault, although this particular engine has only been around for about 3 years or so.
I have been reading up the potential carbon build-up issue for modern direct injection engines, especially turbocharged. It is an inherited issue regarding the direct injection technology, comparing to port injection ones. The main reason for adopting the tech is to meet the ever-growing demands for cleaner engines.
Everyone seems to agree that a properly designed and fitted catch can would definitely benefit the longevity of the engine. The main reason against it appears to be “if it is so good, why the Ford(or any other manufacturers) engineers do not install one out of the factory”. To this question, the most convincing reason is that the car manufacturers do not want to put in something that requires regular maintenance to work and rely solely on the customers to do the right thing, i.e. the can needs to be drained every few thousands of kms, or it would cause more problems.
So I would like someone with the right knowledge to give me some advice on
1. Should I fit one straight away or wait till the warranty is up? Considering I want to keep the car for long term, the initial cost is not the problem and I will endeavour to drain it regularly.
2. How much should I pay for a proper one(supply and install)?
3. Any recommendations on brands and installers? I am in the inner suburbs of Melbourne.
Thank you very much in advance.
