'05 Chevy TB EXT
This is the compilation I promised youse guys ...... in ONE video
Thanks for your accolades and reasoning on the after shutdown vapors getting to the throttle body.That is well-presented information. It is good that the logic/reasoning is included, instead of the common "because the manual says so."
There is one exception. While it is likely within the category of "impractical trueism" even a throttle body drawing nothing but filtered air will eventually accumulate contaminaton (varnish) due to exposure of plenum/intake air and vapors once a hot engine is turned off. Of course, the accumulation will occur dramatically faster if there is no functioning PCV system, and this would likely be accompanied with various other problems caused by poor CCV. However, all TBs will eventually require cleaning.
Your routine maintenance recomendation for the PCV system is highly important, and your explanation is very thorough. There is also the hope that viewers will be reminded that there are various other things which should be a part of routine maintenance which are frequently overlooked.
This is good info….my trailblazer has just started leaving the milky residue on the oil cap and had me wondering what the hell…so this is perfect timing finding this info…thank you sir! Appreciate it!HI Ravalli,
could you tell me what is the fluid you recommend to put in the Crank case vent system?
So many Saturdays. I made it a rule to at least put on pants and a shirt before sitting down for dinner.UPDATE: I have been practicing Safe PCV Cleaning for a while and been adding B-12 every 2-3 weeks or so --- not a rigid schedule --- more along the line of if I really want to put on pants and go outdoors. I'm retired and every day is Saturday - so there!
