The dipstick issue, they corrode because of moisture in the crankcase. And they crack off. To do right, you will need to be able to drill off broken off stub, and replacing with new. Can you maybe get an EZ out in there, maybe twist it out?
I did that already. Used a EZ out. it broke off clean at the flare. All the replacements ones Ive tried so far are about 1/8th in larger diameter. tempted to drill the hole out larger
