Oh yes, i remember these blasted little engines, based on a kent crossflow, only slightly refined (if you can call it that) and rebranded as the HCS OHV engine, then they did something else to them in the 90's and rebranded it again as the endura engine, terrible top end chatter as the valve clearances get bigger and bigger as well, rev one up and the sound resembled a belt sander haha
Every time I spend huge money to repair "my old slightly rusted car that might not live a km more if i'm unlucky" I am happy because it's less than one year depreciation of a newish car. So as long as I hope the repair will make the car survive one year its for free.
There isn't a car on the market where you have to suck out the oil. There is a gimmick where some dealers will suck the oil out of the dipstick hole for what they call a "forecourt oil change" but they don't change the oil filter in the process, so I wouldn't waste my money.
You still just whack off a bolt in the sump (Ford use a standard hex bolt, IIRC it is 13mm), if you remove the oil filler cap before you do this, it lets air in so the oil drains faster and smoother, rather than the gulp, gulp, you get with the cap on. Which means less mess.
Stamps are only important on new/exotic cars. Once they reach about 5 years old, no one really gives a shit as they are worth a couple of grand. I've done all of services on every vehicle in my family, sure none of them have a stamp (well a dealer stamp anyway, they have a smiley face stamp, which is much better if I'm honest) in the book, but a smooth running engine is good enough.
