as i said in my post that was deleted, seriously, cut your losses and swap it.

i use to think it would be cool to have a good running single cam, and whatever, but the motors are shit. even with my single cam in top running order (or as close as possible) it still didnt run well, and was pretty finicky.

best bet- swap it... you can get a ka24de for around 200$, and find the rest of the stuff in a junkyard.
