Hello
My 92 Caprice with 90,000 miles 305 tbi pushed a push rod through cylinder 7 intake rocker arm. I replaced that rocker and push rod and while setting the valve lash on that arm I noticed two others were getting no oil. The new one does now...I'm guessing it wasn't before. I pulled the 2 rockers and push rods to check them out, one push rod seemed to be plugged the other seemed ok but after reassembling them still no oil.
Anybody have any ideas?
Thanks
Tom

 

That oil has to come through the Lifters first, so, if it's not getting up to the Rockers, the/those Lifter(s) must be stopped up.

You could take um out and clean all of them, or, just replace.

 

Got them going....added some sea foam to the oil. It could have helped or it could have been just my messin with the valve lash and cleaning the poo out of the push rods.
Thanks
