I tried using the search feature but only came up on one thread and it did not answer my question. I purchased an oil separator kit from jegs and it came with 3/8" hose and there is no way that is gonna fit over the connecting fittings on the OEM PCV return line or the inlet tubes on either side of the engine. The hose will fit the two 3/8" nipples that came with the filter though. I found this write up Oil-Seperator-Installation on the separator install and he apparently used 1/2" I.D hose so I went out and bought some 1/2" I.D power steering hose (resists high pressure and heat) but I still can not get the hose to go all the way into the inlet tubes or the connecting fittings on the OEM PCV return line. I tried heating the hose to make it easier to work with but no luck. Has anyone else encountered this problem?
