I will tell you this; after driveing about 60k per year and my last 3 3800'* had close to 300k on them. I sold my 98 Bonnie with 247k for 2k to my neighbor and he is still driving it 3 yrs later. All of mine had the gasket done at around 60k and then never again,
They run down the road great, great mileage,I really like the engine, very sorry to see it go. I like the Park Ave'* too sorry to see them go and try to be replaced with the Lucerne, poor replacement as far as im concerned.
I know of many of these engines with well over 200k on them still running fine !
