Piston Slap: The Land Ark's Backfiring Belly?

Hi Sajeev, it’s me again. I am nearing my wit’s end.

My Impala has been out of commission for several months now and as I’ve been telling my friends, the Land Ark and I are not currently speaking to each other. What got us to this stage of our relationship is my seemingly brilliant idea of upgrading my fuel system. I had been concerned about the E10 used in gas stations currently and fearful that we’d soon be provided E15 that would likely start accelerating the degradation of my fuel lines and carburetor bits. I’d purchased a replacement gas tank and sender a few years ago and I found a guy who I thought I could trust to replace my tank and all my fuel lines. I put in everything that could potentially survive E85. I was willing to pay for quality and I did. Everything was replaced but the carb.

  • 28-Cars-Later I cannot remember what happens now, but there are whiteblocks in this period which develop a "tick" like sound which indicates they are toast (maybe head gasket?). Ten or so years ago I looked at an '03 or '04 S60 (I forget why) and I brought my Volvo indy along to tell me if it was worth my time - it ticked and that's when I learned this. This XC90 is probably worth about $300 as it sits, not kidding, and it will cost you conservatively $2500 for an engine swap (all the ones I see on car-part.com have north of 130K miles starting at $1,100 and that's not including freight to a shop, shop labor, other internals to do such as timing belt while engine out etc).
  • 28-Cars-Later Ford reported it lost $132,000 for each of its 10,000 electric vehicles sold in the first quarter of 2024, according to CNN. The sales were down 20 percent from the first quarter of 2023 and would “drag down earnings for the company overall.”The losses include “hundreds of millions being spent on research and development of the next generation of EVs for Ford. Those investments are years away from paying off.” [if they ever are recouped] Ford is the only major carmaker breaking out EV numbers by themselves. But other marques likely suffer similar losses. https://www.zerohedge.com/political/fords-120000-loss-vehicle-shows-california-ev-goals-are-impossible Given these facts, how did Tesla ever produce anything in volume let alone profit?
