Tell that to Consumer Reports, they don't seem to have much good to say about that engine. :lol:The 3.3 has got to be the slant 6 of the 21st century.Longevity of the highest order.
Has it ever needed to be topped off or leaked any? My original trans started gushing fluid out of every seal around 85k. Also the axle carrier bearings went bad causing those to leak and be unfixable without replacing the bearings. Although I guess I can blame the carrier bearing failure on my love for burnouts early in my driving career..Not sure if people think I meant kilometers or miles. I put the k after the miles to indicate thousands...so it is US 312 thousand miles..sorry I had a couple of people message me about it...I'm goin for 500k miles....dont know if I can hit that, the trans has never been flushed or filter changed or anything, at this point I really dont want to rock the boat!
I don't think there's any evidence at all to support that notion. Given the fact that the 3.3 spins at a higher RPM at any give speed in any given gear, one might opine that, if anything, the 3.8 is likely to last more miles than the 3.3.I'm going to guess that it is a 3.3L engine as they tend to be the longest lasting engines in these vans. The 3.8's are good as well but they put more load/wear on the parts and won't last quite as well as the 3.3's
A given fact is that with all things indentical, an engine with a longer stroke and more piston speed will wear the rings/walls faster. The longer stroke also increases side loading on the cylinder walls which adds friction there as well. Not to mention the higher power output puts more load on the bearings. Either way, these engines are good for many hundreds of thousands of miles.I don't think there's any evidence at all to support that notion. Given the fact that the 3.3 spins at a higher RPM at any give speed in any given gear, one might opine that, if anything, the 3.8 is likely to last more miles than the 3.3.
Long story short, I doubt there is any statistical difference in the number of miles these engines can go under identical conditions.
