skydawg Posted October 24, 2021 Share Posted October 24, 2021 The turbos in cars from the 60`s were routinely having to be replaced long before the engines were worn out.Is this true of the turbocharged 673 engines from the B era?

doubleclutchinweasel Posted October 25, 2021 Share Posted October 25, 2021 I think I only ever personally saw one lose a turbo. Not sure what the cause was. I don't think there was a major issue with them. Quote "Eagles may soar, but weasels don't get sucked into jet engines."

Freightrain Posted October 25, 2021 Share Posted October 25, 2021 I dont think they are referring to cars only, but vehicles in general. Poor maintenance was likely more the cause for failure. Oil back then was horrible also. Most engines were wore out by 50-70k miles. Today its 200k+. Big truck engines have 2x, 3x lifespan now also. Quote Larry 1959 B61 Liv'n Large......................

Popular Post theakerstwo Posted October 25, 2021 Popular Post Share Posted October 25, 2021 (edited) A big problem back years ago with turbos was That they were run too hot on the exhaust side cooking them.Older engines did not have a fuel ratio valve and if the turbo lost boost for some reason due to aleak the fuel would keep fuel at max setting causing hi exhast temps.The newer engine have a fuel ratio valve or boost sensor that will limit the fuel to the engine if the boost is not high enough so the turbo is saved the high temp.
