dauntless/hei -not firing on one whole side

ok guys got a good one for you , first time for this one............. my dauntless 225 with HEI, is not firing the 3 plugs on the driver side , you can unplug all three from the cap (AT THE SAME TIME!!!!!) and it still runs, the exhaust is cold from that bank and does not sound good at all -spudering , unplug any from the pass side and it will die/ stumble like normal.drove it about 50miles on 3 cyl.back to camp , I did have a spare hei module in the glovebox, switched it out but did nothing.........

other than not firing,the motor sound fine bearing wise and I have full pressure.
thinking maybe somthing with the buick valve train assy? maybe a flat cam?but all on one side???????? I think a compression test is in order tomorrow.help?anybody ? I am waiting for orders on how to proceede. just throw it out there thankx,

 

I think you are 180* out.:v6:

 

no,have run it this way for a few years , i've not changed plugs /wires/ timing . this weekend on the trail we did cleaned out the cap, rotor and sanded the contacts,with no change ...........always plenty of power.timing is steady ....... even if the timing chain was bad or it skipped a tooth it would not affect one whole bank ,,,,would it?

 

yes. a very nice spark at the plugs,
will try to blow it tomorrow.
NOTE; I run an Offy 360 dual plenum the one with the divider with the little square notch taken out of it , then to an adapter to run the 2G.

thanks worth a try.

I have a 390 cfm I could throw on there to check it out.

 

If you've got good spark on both banks then it definitely points to a fuel issue. common to get some gunk in the jets or idle mixture passages on one bank. Do like Patrick mentioned and blow some air through it, bet you will see an improvement.

 

sounds like bad piston return springs. they like to go bad one bank at a time.R) i agree with the others it sounds like a piece of junk in the carb

 

mx -, I would't think it was the piston return spring 'cause it is puffing cold air out the exhaust.

I really surprised that little motor has lasted this long (over 10 years ).I ran it on 4 qts of oil for about 8 years 'cause thats whats stamped on the dipstick. and incase you haven't noticed ................my jeep has a way of finding the WORST angles to run at on some trails and has lost oil pressure ,and spit raw oil out the exhaust ,but the trail was completed under it's own power.

I'm stupid, I know ,I can't help it.

 

How is your blinker fluid level?

 

well, that just brings the suck,,,,,, I could have stayed out in the dez 1 more day., I pulled the needles and shot air threw the line and wal-la it's fixed .just sucks 'cause I have OBA and could have done this on the trail..

pull a wire and it stumbles on every cyl. ,,,,just like normal. ahhhhhh

THANKS GUYS,,,,,, I was preparing for some kind of bad !!!!! quess ,I will put a better filter on it .

I couldn't :iagree: more. Makes the whole thing run better anyways.
