If you have had long-term, specific experience on the AVL 500cc engine, I would appreciate your advice. I've read Forum entries for one hour.
I've changed oil only 3 times and continue to have a problem with LOTS of oil BLOWING out of oil catch can.
Last time, I :
1) ran engine for one minute(to fill engine sump?, to warm oil to enhance draining? or, to attain the "true" volume of the oil?)
2) drained oil(did NOT change filter/oil in oil pump!--my choice!)
3) filled new oil
4) checked dipstick level, WITHOUT screwing dipstick down
5) it read "Full"
6) ran engine again for 1 minute
7) checked dipstick level--(WITHOUT)
it read " one half" on the H/L dipstick marking
9) filled it to "Full"
10) took 60 mile ride(97 degrees Fahrenheit) and LOTS of oil blew out of catch can.
QUESTIONS:
1) In reality, WHY does the engine need to be run for 5 minutes("the manual says")
2) what is your foolproof, experienced system for changing/refilling oil(personally, my aging knees and back tell me to SHORTEN the total time required!)
3) Without my disassembling the engine, what are the SIGNIFICANT unique construction details Of the AVL engine that seem to require such Bugaboo written on the Forum re oil changing?
4) I don't need "quantities of oil" just dipstick readings.
