What a pain that was haha. I was starting to think it might have been time to start trying new plugs, injectors, coils or that maybe I screwed something else up. But nope, i just learned how to set my timing!
Thanks again to everybody that pitched advice, much appreciated!
Congratulations ! Like so many things, you only have to go through that process once to understand it - then it becomes "knowledge". Kudos for keeping at it !
Another headache. Whoever installed the timing belt installed it a tooth off so I have to pull it and reinstall..... yay
Ah the work of a previous owner
What I would give for an untouched original that's been tucked away
Annoying but easy enough to remedy. It'll run a whole heap better once you've reset the belt. Can you get your hands on a dwell/tach meter? You can dig up some hidden performance if you retune the ignition timing once the timing marks are correct.Quote:

Anyway, I want to install the tach just to be able to keep a more detailed eye on how the truck is behaving but I also haven't forgot about you tuning method, Geezer. In fact I had my mind on it when I thought I was close to being finished yesterday. Once she's dialed on the timing I'm gonna give that a whirl. Also, I was able to slip the timing belt of of the crankshaft sprocket and maintain the tension as I lined up and the camshaft to the correct mark and reinstalled the belt. Was this a "slick move" or did I make a mistake trying to take a shortcut?
Some trucks had the tacho instrument cluster as an option but they're not overly common. I've slipped belts off and on engines without undoing the tensioner without ill effects (I had a belt blow at a friends place on a GM family II 1.8 and that engine is a b@stard to work on...) As long as your marks are in the right place it'll kick over and run (make sure you've got the diagnostic/tune wire grounded in the engine bay so it accepts the new tune).
Now if I could only find my keys....
Also, DO NOT FORGET you have two balance shaft cogs to also put on the mark.
Tortron, you mean the holy grail? Yes, what a find that would be!
there is a wire on the firewall that the tach can be connected to - there is a thread on here that shows where it is.

Remember that the only reason for this B belt and tensioner is to turn that balance shaft: it serves no other purpose. But without it, your engine will shake like a dog shitting tacks. The balance shafts are to counter-balance the vibrations the engine naturally makes.
Your crank pulley should be at #1 TDC, as you left it. As well, the cam gear should be close to TDC, too. Remember your timing marks on the cylinder head, because this is one of the errors guys make: using the top of the cylinder head instead of the actual timing mark, slightly below the top.
Pennyman, can you send me link for that, it would be MAJORLY helpful! And thanks for the info. If I don't get a link to the thread, I'll definitely look into further myself, thanks for the input! Royster, which belt is considered the b belt. I know there a a third sprocket/gear to line up on its timing mark but I'm not 100% sure with one it is. Does that pertain to the "B belt" you're referring to? Thanks in advance........ You guys are f****** awesome!, I appreciate you guys more than you know!
Also, I k me my timing should advance while the engine is started and I'm dialing it in with the light but I can remember exactly how far, anyone know right off hand?
Sorry about the typo! Anyhow, I'm time at 0 degrees, TDC. When I start her up, I need to dial the timing in exact but I can't remember how far advanced it should be. I want to say it should advance 5 degrees? Does anyone know for sure? I know I'm close but I took her for a test drive around the block and I didn't like the way she felt. It just wasn't smooth at all.
Again, she's a 1990, 2.4L, 4 cylinder with a 5 speed manual trans.

If it still runs rough you'll have to check all the ignition components and make sure they're in spec.
The B belt is a small belt on the left side of the crank, and it turns the balance shaft. The timing on it is important because it dampens engine vibration. The right-hand side (facing the engine) balance shaft is connected to the oil pump (lower right-hand cog as you face the engine). If you're getting a lot of vibration, chances are your balance shafts' timing is off. It takes some effort to get all this timing right, so don't be discouraged if you have to do it again. (Read my build thread and you'll see I had to do several things over and over).
You really should invest $20 in the Haynes service manual for this truck. Though they lack some key information, they will help you with photos and techniques. Many say an online manual is sufficient, which is great if you have a computer in your garage. The Haynes manual is right there, and requires no electricity.
Hey, LowLifer, what's the latest on this?
I've been busy with some.... personal drama. I'm trying to get back to it today. I wanna make sure that everything with a timing mark is lined up where it should be at TDC. Last time I was under the hood I was removing the time cover to make sure everything looked good underneath and I hit a speed bump. There's one bolt that I can't get ahold of, it's tucked behind the crank shaft pulley. The pulley is blocking me from getting a socket onto it and the cover itself has an indention for the bolt head but doesn't give enough clearance for a wrench either.
I think one of these might do the trick but I haven't had a chance to pick one up
Here's the culprit. I bet Mitsubishi had a good laugh when they put that bastard in there

To honest, I'm not even sure the angled wrench will do it
You're going to need to take the pulley off, anyway, so a socket WILL get that bolt off. If you don't take the pulley off, you can't remove the timing cover...something you absolutely need to do.
That's what I figured. I'm gonna head out the in a few and pull it off. It's just a few bolts on the front of the pulley, right?
