I think it's a lot to do with how it's designed too.. I kept an old hatchback bmw made in 2000 and that thing already have bit of plastic parts in the engine bay (coolant pipes no less) which are just time bombs. parts and labour costs are usually why people decided to go newer cars. good job on the old porsche though, just don't get the one with starter motor in the transmission case.. some of them are maintenance nightmares
- _yb2s 2y agoI'm not familiar with BMWs of that era, but other German cars from that era, the plastic cooling system pipes will likely last forever- they don't corrode or crack like metal pipes would over time. For really critical things like through hulls below the waterline on boats, plastic pipes like glass filled nylon (Marelon) are considered safer and more reliable than metal, because they never corrode, and are much physically stronger than a comparable weight metal part. I grew up with 1970s European cars where every plastic or rubber part would fail eventually, but by the 90s the materials got much better.
- alliao 2y agothat's good to hear! it's the only weak spot on that engine M44, and that particular plastic cooling pipe is in a nightmarish place right up against the firewall. Need tiny hands if you want to replace it while the engine's inside.
