davidke20 zeoneDo you know the hose size that connect between engine head loop back to intake hose? Plan to fit a OCT on that, that day clean TB notice the intake hose is very oily, which i think contribute alot to my dirty TB. Thanks.
Hi Bro...

Suggest 2 options...
1.
a) Remove connecting hose.
b) Connect separate standalone mini PCV air filter to rocker cover tube/"inlet".

c) Block tube @air inlet/point b4 TB.
NB. This simple mod provides good 1-way airflow circulation for rocker cover space ie PCV ventilation sys.
2. Use a 12 mm fuel hose 2connect a simple fuel filter (as OCT) in-btwin rocker cover & TB point.

An example posted 4sale somewhere sometime ago...

NB. This wld collect oil fumes "sucked" towards TB point if & when sudden strong vacuum caused by sudden large throttle openings. ..

Best wishes!
