Thread: sbc has a mis

Tweet

i started my truck up to head to work i let it run 10-15 minutes before leaving cause it has a cam in it to get everything warmed up then i drove maybe a mile to the gas station and picked up some stuff then i continued on my way to work and as i was backing out of the gas station i noticed a mis i went down the road and it was getting worse so i turned around and went back home. i changed plugs wires coils distr cap rotor button and it still does it i went back threw and checked my valves and found a bent push rod changed that it problem still persists any help ?

pushrods usually bend after something hits something ... do a compression check for a bent valve ....

I would check compression also. Had same thing happen to me once.
Turned out to be broken valve spring.

checked everything out and found that it was a broken valve spring just finished changing it out runs perfect again thanks for the helpful info
