Yeah throwing in some interposing relays is my default solution, but I want to make sure I've exhausted my other opportunities before going that route. Simple solution seems like it'd be to throw one on the ignition switch output as that gets me a minimum of 0.5V boost, but might be worth looking at doing it to individual loads as well. One "good" thing is the Alfa doesn't run the headlights through the ignition switch, so at least that isn't a problem like it is on most cars. Downside is there is something stopping me from leaving the headlights on haha
@pip-bip There was some concern it was valves and pistons having a coming together, but to me the randomness sounded more like I'd dropped a bolt/nut in a weird places and it was causing havoc.
Timing chain being the problem is a relief except for the whole "how did it get like that?" concern. I'm just going to gloss over that assuming I had like a tented link on the crank or something, and move along...
Yes, and it sounds like what you have going on here. The cams look like they're 180 out because they may have been, since they turn half crank speed there are really two options for when #1 is TDC - and which of those two you pick determines if that TDC is the end of the exhaust or the end of the compression stroke. If you put it one way and think it's the other, your distributor is now backwards from where it ought to be and you're trying to get power from the intake stroke, which makes for a very poorly running engine (if it'll run at all). Moving the plug wires along the cap by 180 degrees effectively flips the distributor back over but without rotating it the whole way, and band-aids the problem.
It could also be that you killed the ignition coil by shorting it to ground.
@jawzx2 Marking the crank pulley helps you find TDC so you can put the engine back together, but doesn't guarantee TDC will still be there after you fire it up.
There's probably dots on the crank sprocket, but you'd have to pull the crank pulley and timing cover to see them. Maybe you can do that in the car, but given the shenanigans involved in removing/refitting the head, I'm thinking not.
@akioohtori I could not tell you which ones they are, but I know there are non-Kei versions of some Kei cars because they have more power. Also some Kei cars take well to tuning if they’re turbo charged. Might not be a highway warrior, but still be pretty quick.
Alternatively, you just buy a fast but small JDM car. Wouldn’t quite be a Kei, but close enough, but would be significantly better on the highway. Or would you want a replacement for your S-Type R? Then get a fast but comfy boat, or perhaps something a tad slower, like a Century. I have no clue if any of that sounds fun, but just tossing some ideas around.
@akioohtori do they have one of those little sample stations setup? Cos you should take a lighter to it and see if it smells right for an Italian car cruising up the Amalfi coast.
