Piston Slap: So Hot, Yet So Cold!

Hello Sajeev,

(I really wanted to put the “n” in there.)

I have a ’97 Prelude that will sometimes cycle on and off its air conditioning when it’s unbearable hot outside (June-September here in Phoenix). Air will come out nice and cold, then it will get real warm suddenly for about 30 seconds before getting cold again. It only happens when it’s extremely hot outside and I’ve been driving for awhile. It works fine the majority of the time. What do you think?

  • 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?
