Bore scope camera to inspect visual and CAT cleaners available commercially?
The new PCV will be inadequate and additional measures taken required if the old one didn't work right?
I believe NostraJackAss has many tricks, tips and directions - sometimes counter to general commercial currents.
Also, I believe that just because there's a product made for it doesn't automatically make it a good idea to use, especially on a VAG vehicle. I see two types of products out there 1) fuel additives and 2) cleaners to be used after removing the CAT. How would The Wise One recommend proceeding if the CAT is indeed heavily coated with gunk?
Honestly, I'd like to be lazy on this if I can, but if CAT needs removed I will take it to a muffler shop and go from there.
Currently installed PCV is generic and was approximately 1/10 the cost of . I assume, based on the issues other non- products cause/have caused, that going to alone will be an upgrade.
I replaced it because I suspected blockage in oil separation system internal to PCV unit, hence the buildup in the IM and intake valves, but now suspect I would have been better off leaving the nice expensive one in place and adding catch cans (which I will now do anyway in the near future). Going back to anyway. Also, am wondering if the oil return line is plugged and will check that as well (the configuration is that, after cyclones separate out, oil drains down into block).
