Is there any reason I maybe overlooking as to why I not getting any oil to through the pushrod. My situation:

New Morel link-bar lifters, which have been pre-cleaned with solvent and soaked in oil. Pushrod free & clear , valve lash set properly. all others pumping fine except #2 exhaust ( thought I had a bad pair sent it back to morel and installed the new one that was sent, and the same situation occured.... pumped for awhile and quit). Any thoughts would be appreciated.
