Can a 2.2/2.5 run with distributor 180 out?

**Shadow** · 08-05-2009, 11:57 PM

Like the title says, will it run? I would have thought not. The entire mtr would be firing on the dead stroke...no? We took a 2.5 apart and redid the timing belt and the distributor was 180 out firing in the #4 position with everything lined up on the belt. Suffice to say I switched the distibutor back so it was firing on #1, but the car drove into the shop like this. Anyone ever hear of this before?

How was it 180* out? Was the dist backwards, but the hep and cap on right, or was the whole deal on backwards? My old roommate put the cap on backwards (the rest on normally) and it would not run at all. I had to fix it when I got home.

I have never seen a 2.2/2.5 run 180* out
I have seen were the I Shaft was timed 180* out and the dist was installed purposely 180 out.

I bet that's exactly what happened, the previous owner/mechanic timed it wrong and just re and re'd the distributor to get it running.

The oil pump was clocked right acording to the itermediate gear, all the marks/gears were lined up correctly with the timing belt. But the distributor was dropped in 180 out. So, to look at it, it looked perfectly normal. For a matter of fact, I timed the car at 12 deg a while back and it timed perfectly and the distibutor sat right where it should at about 12 deg timing. Only thing out was the distributor, firing on #4 when it should be on #1. I thought about this some more (after I posted last night) and came to the conclusion that it is possible. Correct me if I'm wrong, but as well as the spark being distributed to the wrong cyl's, doesn't the hep also govern which inj's fire? If that's true, then you would get spark and fuel for each cyl and that's all you would need. Next Q, can anyone think of anything detrimental that would happen with the mtr running this way?

at 180* it wont run at all.

**kermit** · 08-06-2009, 12:27 PM

how were the wires hooked up??

if the wires were 180* out and the dist. was 180* out, then i would think it would run.

When you say installed 180 out, was it just the rotor that was 180 out, or was the whole dizzy in wround? Like, did they have the flat side of the dizzy towards the block?

lol +1 thats what i was thinking

as long as the wires fired 1-3-4-2 it wouldnt matter if the rotor was out 180

**t3rse** · 08-06-2009, 01:39 PM

I don't know about stock electronics, but with a standalone which doesn't account for direction, the motor will fire up with it 180 out and back fire and spin backwards until power is cut, which will lead to blown tb gaskets and all sorts of fun...ask me why I know this....

was the #4 wire on the dizzy hooked up to the #1 spark plug? stange

Negative, the distributor was installed correctly, flat side to front, just the rotor was 180 out. All the wires were in there correct location.

**Force Fed Mopar** · 08-06-2009, 03:24 PM

Was the firing order on correct?

I can't see it working as the #1 sync will be also out 180 deg,

Yes, firing order correct. Take a perfectly set-up 2.2/2.5, lift the distributor out of the block, spin it 180 deg and put it back in. That's what I'm talkin about.

could not run the way you say it was when it came in. when#1 is at tdc top of compression stroke ready to fire, # 4 is at tdc end of exhaust stroke and ready to start intake. In that case it would fire #4 with no compression or charge and waste #1 comp and charge. Intake and exhaust valves would both be open on #4 from cam overlap.
#2 is at bottom of power stroke and # 3 is as bottom of intake stroke..................................I think...........yup, thats right. How well did it run when you got it?

The whole mtr would be running on the "dead" stroke. I having trouble figuring it as well.

Like I said earlier, I timed this thing at 12 deg and it was running boost pretty normal. The only other explanation would be that the I-shaft was 180 out as well. Just doesn't make sense, because when I lined everything up for the timing belt, it was all dead on. I see it all the time when ppl don't index the oil pump with the I-shaft and the dist is hell out to get timing, but this one was smack on with the exception of the dis being 180 out.

The injector batch fire would be out of phase but that wouldnt matter much, but the cam timing would be 180 off and that would be a none starter.

Cam timing with crank was dead on, only spark to the cyl's was 180 out.
