My understanding if you have a prop stroke then the bulk strip can be done by a LAME organisation (that is qualified) or aviation engine rebuilder. There are still some Aviation engine re builders around that are good on VWs
A friend 2 or 3 years ago convinced himself the engine had an issue (about 800hrs tt) and was pulled down by some VW person in Victoria. I explained he had to go to a CASA engine re builder which he did then. Platinum 300 in Victoria found no issues but chose to fit new rings and bearings like a rebuild (aircraft was bought from an estate so sat around for 6 years) . They had to have on file ALL manuals and chose to get the heads OH by the old guy here who did lots of aero enterprises machine work. The reason for the rebuild was faulty mechanical fuel pump! We in Australia now can go hours "on condition" in most aircraft (excluding charter but includes training). Thus as I see it he just keeps flying well beyond the 1000hrs subject to oil consumption etc. During last 200hrs I get oil analysis (I now use ALS), wash out oil filter core in blue icecream container and examine with head lens. I place a magnet on outside of oil filter and always fit a digital CHT that monitors all four cylinders. If compression is good and oil temps and pressures then keep flying in AUSTRALIA. GFA must mirror CASA requirements I believe. Personally I am over chasing up genuine parts except where parts are critical.
