this engine is tough as fucking nails tho i s2g, one time i managed to drive on it with like 2 quarts of oil in it when it requires 5.5 (it had a pcv valve issue that sucked oil into the intake via the valve covers) and the engine was happy as can be, no dammage, this was like 8 months before i drove 1600 miles down to tulsa and have driven it another probably 5-6k without an oil change and she's still purring like a kitten...
@plausocks AX4N specifically
@Motodrachen yeah they put that in a lot of overburdened applications, it's basically fine in the Taurus but the Windstar and freestar are famous for burning them up
