Is the pressure relief valve in the oil filter mount?
Pressure Relief Valve on 1986-1991 models (in the oil filter mount) (This overview is not intended to present or explore every detail of any of these parts. See the REF section on Understanding Oil Filters) The oil pump is hydraulic and moves oil efficiently.
How does crankcase air pressure affect sump oil?
Crankcase air pressure is mainly generated by the up and down movement of the pistons. The downstroke of the piston causes the volume underneath the pistons to decrease which puts pressure on the oil in the sump. 6) It helps to push sump oil up and out the scavenge passage to the return side of the oil pump.
How does static oil pump affect crankcase pressure?
Static oil pump pressure has already been dissipated by the time it reaches the crankcase. Likewise, crankcase (CC) pressure will have a constant change in velocity. Oil in the crankcase adds resistance to the air pressure generated (raising the pressure). 2004 and up models have feed oil piston squirters which adds more oil into the crankcase.
How is the oil fed to the Evo oil pump?
See also the Evo oil pump section of the Sportsterpedia. Oil is gravity fed from the oil tank to the oil pump. In essence, the oil tank is mounted above the oil pump and the feed line runs down to the pump. However, there is also a vacuum on the feed line to the pump.

Why does the Mini Cooper oil filter have a cage?
For this reason, the early production MINIs have a spring loaded plastic ‘cage’ built into the oil filter canister cover. This ‘cage’ provides a rigid structure within the filter to maintain its shape under pressure. The cage also helps to ‘seal’ the top of the filter for proper oil circulation thru the filter.
How does a Supertech oil filter work?
The SuperTech filter does technically have a bypass valve. Sort of. If the pressure in the canister is high enough, the pressure on incoming oil will push the anti-drainback valve back, which will push the cartridge back, which will flex the spring at the end of the canister and create a bypass.
What causes oil to bypass the oil filter?
Aftermarket oil filter with inadequate ‘stiffness’ on the ends of the filter causing oil to bypass the filter (Wix filter caused this problem for one customer). The factory oil filter has a rigid black plastic base on the bottom to press against the valves at the base of the oil filter housing. Helpful Hints for changing the oil…
