Oppo, what are some extremely unreliable cars/engines, specifically ones with head gasket issues due to different block/head materials? I’m trying to talk my Materials Science teacher into buying a beater with potential head gasket issues off craigslist so that we can watch them fail catastrophically. Naturally, the difference in block and head materials is very important as this is supposed to be a teachable moment about different rates of expansion in metals. These cars should be obtainable for less than $3k. Thanks!

Candidates so far:

Mid-late 90s Accord with F22B

‘95-’99 Sebring/Avenger or DSM

‘99-’05 WJ Grand Cherokee with 4.7
