Hi I’ve just bought the fram oil canister for my okrasa 30hp engine so I’m now in need of the oil hose kit..
Does anybody know where i can buy it from??
Possibly in the uk?

Has anyone modified this type oil filter to be full flow?
I imagine welding on larger fittings for larger diameter feed and returns

It would have to be plumbed differently and the filter would have to be able to handle the pressure.

In the context of drawing oil from a secondary circuit initially supplying the pressure sensor and not at the outlet of the oil pump, filtration remains not perfect
That said, should we increase the quantity of oil if we have installed a Fram FP3 like here? I suppose that the oil in the filter goes back down into the crankcase by gravity, when the engine is stopped.
Firstly, I would tend to think that we should add approximately the same volume of oil as the filter contains, in order to avoid any planing in the suction of the crankcase...
Am I wrong ?
I also wonder about taking the oil from the location of the pressure probe: we take oil which was supposed to lubricate the vital parts to send it into the filter. Obviously, there are fewer of them going into the landings... |

I would assume when Okrasa designed their dual port engine kits and wanted to "add" an oil filter as an accessory, using the oil pressure switch area would have made
it an ideal location WITHOUT completely disassembling the engine in order to drill / tap (metal shavings) an accessible and convenient oil galley.
Their long 14mm hex bolt added at the oil pressure switch location is identical what the early Pre-A Porsche 356's used in their engines. The concern about low oil pressure is measured by a 2mm controlled orifice in the fitting. This allows sufficient oil to flow to the oil filter but at the same time, maintain proper oil pressure to the bearings. This design is brilliant as does not (high) pressurize the oil inlet line at the oil canister but rather maintain important oil pressure within the block.
Additional oil is added to fill the oil canister, oil cooler if used and oil lines. Some oil does drain back in to the crankcase but not all. Whenever I start a freshly built Okrasa engine, I add 2 1/2 qts. of oil to fill the crankcase and fill the oil filter canister with the element inside. This will assure me that I have filled the "large" voids in the oil system. After you shut down, I check the oil level at the dipstick and add oil if required. Of course, if you have a deep oil sump, you will need additional oil.

Thank you very much Joe for all this detailed and common sense information.
Have you had the opportunity to evaluate the approximate volume of oil filtered by this device? |
