Misfire

[64nailhead]

And yes I jiggled and twisted the push rods. And what is eioc method?

Read this article, it describes how adjust valves using the EOIC method. You will need a method of turning the engine over by hand - you CANNOT use the bumping the starter, and you can't turn over a SBC with the harmonic balancer bolt either. Not knowing what's on the front of your motor, you can use the alternator pulley nut (difficultly). Or buy or make a tool to attach to the balancer via the pulley mounting bolts. Something like this : https://www.summitracing.com/parts/pro-66782. I made oe from an old pulley and junk socket. No matter what you use, pull the plugs to eliminate any compression build when rotating the motor.

Don't take this the wrong way because it's not my intention, but the putting the engine at two locations is ridiculous IMO, but in your case without an accurate measurement of TDC, it is nearly impossible to hit 8 of the valves in the correct position. Almost undoubtedly you have valves that are loose.

Also, it's a good thing that you couldn't get the lifters out with all of the crud/debris in the motor. That means there is less of a chance of some debris getting into a lifter and boogering one of them up - lol. The reason they are not coming out easily is because of the amount of similar crud buildup on the part of the lifter below the lifter bore. At the point you are at with this motor, I wouldn't worry about. There is a chance that running a quality oil and filter and changing the oil regularly might clean them off, but maybe not as well. No matter, there is no need to worry about that at this moment.

Will lose valves cause a misfire? Carb pops when I rev it.

Ok so don't bash me for this.... Lol I was looking in the wrong place for the timing tab (my Malibu has it in the 3 o clock position) so after flashing lamps in there I found it all grimey in the 12 o clock position (was hard to see with water pump in the way) but I finally was able to set it where I wanted to adjust my valves and noise is gone. Still haven't fixed my exhaust though so I'll be on that today (there's a lot of rain in Houston) and I was also able to time my dizzy with no misfire. Thanks guys. I will post a video after I fix the exhaust because I need to know about any sensors that will cause my engine to lose power. Thanks God bless u guys.

After watching my video I don't know if you'll be able to make out what I'm saying.

I fixed the exhaust manifold leak with gaskets and now it sounds like I gotta fix the flange exhaust leak. I don't have a misfire anymore because I was able to time with timing mark. I adjusted my rocker arms again this time half a turn.

My concerns are ; is there supposed to be vacuum suction from the dizzy advance? There is none. Neither from the dizzy nor the carb. Also the fitting by the water hose on the intake with the 2 black rubber tips, there is also no suction. Is all this normal?

And last, this engine is a tbi engine from a newer vehicle so does the knock sensor still apply? Where is it and where do I wire it to my 81 elcamino?

Thanks guys!

Knock sensor you do not need

No vacuum comes out of the distributor

The vacuum is provided by the carburetor. put your finger over one of the vacuum lines on the carburetor rev the engine slowly.

If you feel suction from the port attach the hose from the distributor to that port.

The hose on the intake with the 2 black rubber tips remove and install a plug or keep the vacuum caps over the rubber tips.

What did your intake manifold look like before you installed the carburetor the top or bottom one?
