Above you can see broken output shaft after another stand still burnout. Interesting that original version is not solid style, meanwhile stare I put in from diesel version is solid - not a tube style like original. After some thinking come with conclusion that this was caused by wheel bounce, cause original engine/gearbox mounts and not enough rpm and wet road and tyre pressure or just some of mentioned :) Anyhow polyurethane ones rest on shelf already and be tested some time around.
After another nice ride check underneath by beater and found oil soaking down from the engine. After some inspection made assumption that oil filter housing seal is done. Omg, it was done totally, rubber was like really hard plastic. After googling a bit, found out this is another standard bmw thing, basically 20 years made their part. This fix was cheep, 2.5eur for elring seal, and relatively easy. Also changed oil line from oil housing into vanos unit, was leaking slowly. Those kinda fixes are kinda optional, but to my mind when car is used on it's limit become required, or if want car to not fail randomly. Also new termostat went in this round, not liking fluctuating engine temp at all. Note, woring on termostat this happened But welding machine helped me out Old termostat had strange o-ring stuck between parts. So far so good, need winter tyres on the front and hunt for action time.
