The quest continues

Hello all,

 

I have been rebuilding a 82 4 door Gl10. My friend bought it for 300$ with a rod through the block. I had a 84 hydro motor sitting around so i gave it to him. 

We tore it down completely and sent it to the machine shop. 

Had the block halves cleaned and honed. The heads got .03 milled off. And delta put a Hp grind on the cam and resurfaced the lifters.

 

Now i am in the process of putting it all back together.

I have the left head back on the motor, however I'm have problems with the push rods.

 

The rear two rods can jiggle easily yet the front two have no play.

Also, some of the lifters cannot be compressed, no matter how hard i try to push the pushrod into them. Are they the problem?

I currently have them soaking in solvent but it hasn't made a difference. 

 

 

Thanks

I disassembled each lifter and cleaned out all the carbon.

They are all free now and can be compressed. The only difference is they all have slightly different spring rates. One in particular is very weak. I'm referring to the internal spring of the lifter. I put the weak lifter the slot for a exhaust valve.

 

After reassembling the rocker arm assembly, the jiggling pushrod issue is gone. It must have been the seized lifter causing the issue.

 

Will having a hydraulic lifter that can be compressed easily cause any issues?

 

Thanks
