If you go to a dollar general for 5.00 you can get a gallon of mean green degreaser i used 4 gallons in a tall kitchen wide garbage can fill with mean green and let all your parts your taking off the timing cover the head etc and let sit for 5 days you will see that come out like its brand new and clean up awesome same with oil pan clean rinse it off primer it with heat primer for motors and get some engine heat paint of your choice and have at it
The purple lines? That's Dino's camera which we rarely use, he had to use that because I, Max, was not there. And to swap in a dual cam you need a dohc wiring harness and possible the ecu too? And it would cost more too, you need to buy a new engine
Google with it's "wisdom", and "Fairness" agenda and IGNORANCE could not find me any real videos or any information whatsoever on my search for 1990 Micra Ma12 4 cyl. engine rebuild. I searched over 2 hours and this is the best I could find on RU-vid (a division of google) and get a young guy who did not get into the build as much as tear down. Good on ya. But your methods at cleaning parts is very messy and I bet you got huge dead lawn spots. I am still searching for some specs and will try a dot net. Stop spraying everything !
