yeah agreed always run your engine to adjust a hydraulic setup. and +2 on the wiring route...i have messed myself up on a tune up before by having two of the wires mismatched. and also about the msd coil..usually you want to run a good set of low resistance wires when running a better coil otherwise it will be too much voltage trying to make its way threw some high resistance wires and jump off the coil...just my 2 pennies

 

We adjusted them with the car off, the started the car with no covers on to make sure they were all good. We heard no ticking, and they are all doing well.

It seems like heat plays a role in when it backfires. I can have it idle for 3-4 minutes and no issues, but then it will start to backfire, more and more as it runs (gets warmer).

 

I'm going to have to say save your time with the other things you wanted to do first and just go right for rocker re-adjustment.

 

yea...back each of them off enough so you can hear them tick and then go clockwise 1/4 turn, once your done with all of them I bet it won't backfire anymore. And yes it will make a mess, but theres not much of a way around that.

 

He has roller remember.

 

yea, hydraulic roller, right?

this method is pretty universal whether it be hydraulic or hydraulic roller

 

I know we have hyd roller lifters, I'm talking ROCKERS

 

yea even with roller rockers this is the method that I use, the only way this would change is if the rockers were not stud mounted and were instead shaft mounted, in which case i believe they are just torqued to a specific rating

 

I was under the impression that you use a feeler gauge when adjusting rollers? Then again I didn't look into it much since I traded off my RRs.

Here's a better link for him

That is the method that I used, I did not get around to checking rockers yesterday. We used Shoebox's IOEC method with the car off, then started it with the covers off. It took a little while but oil did flow through all rockers, and they did not tick at all. Are you all thinking that they are to tight and I should try it again backing each one off? I guess that is a sure fire way to know they are adjusted properly.

Im wondering if its not electrical since it seems to start backfiring as the car warms up. I noticed last night that the headlights are on when the key is on, and the switch is off. I also have the right blicker light on (not flashing) the dash on when the key is on and blinker off. In addition the blinker light is on (not flashing) when I turn the lights on without the key on. Bad ground perhaps? I did have the battery relocated during the mods so that could be it.

Im gonna connect a jumper cable to the battery and the other end to the block just to double check.

 

That is precisely my thinking. That you tightened them too tight due to the lifters not being fulled pumped up anymore, and when they DID finally pump up, it's not a bit too tight and causing a valve to be open a tad during a stroke.

Sadly, you can't exactly pin-point which one it is and you'll have to do them all :S

 

Sounds good even if that doesnt fix things, I can at least feel good and know they are adjusted propery and mark rockers off the list of things possible wrong.
