RTB, Roller Throttle Body safe cleaners....

[Reiver]

I know regular carb cleaner can harm oxy sensors and plastics....what is/are you using to clean the rollers... I see 'Throttle Body Cleaners' and assume they are good to go but you know assumptions.

The solvents used to clean mass flow sensors work pretty well and don't harm plastics. I'm curious to know why the roller barrels need cleaning. Is there build up on them?

There is a bit of build up on the exterior of one barrel ... foam filters...of any type, let in more particulate matter than cellulose.  Simply physics.... more airflow equates to less filtration, that includes nano filters or whatever name one wants to slap on them...  Many use the foam as is...I will use a light exterior applied oil made for foam filters.

Actually, with the roller barrel intake, much of the grime you see accumulating is due to intake reversion - un-burnt hydrocarbons accumulating. For vehicles with a bit of mileage, the only comprehensive way to get all the grime out is to remove/disassemble/clean the rollers. Otherwise, the grime that accumulates between the valve and bore gets wiped back onto the valve surface.

Thanks for the input..... you guys did the RTB conversion/dry sump on this car.  I purchased it out of Washington State and the records came with it.  Once I became familiar with the RTB's, sent a build instruction sheet...I've gotten them synced.
