Long story short, I recently picked up my Pops old car after sitting for over 2 years. So far I’ve gotten an oil change, drove over 4.5 hours home, took it to the BMW dealership to knock out all open recalls and to get a condition report - miraculously aside from the cosmetics, everything seemed to be fine aside from needing new rear brakes and a rear tire. I asked the tech to check out the “knocking” sound I hear coming from the engine bay, I was told it was either the belt tensioner or the timing chain lol. The tech said he wouldn’t put a dollar into it 😆. I’ve already ordered the tensioner, belt, and pulley. My plan would be to use this as an A to B car as it gets better gas mileage than my other. E90 heads, am I doomed?
