No oil to rocker arms

[Turbo-Bill-Boston]

Hi Jack,
Just replaced my stock GN's timing timing chain. Tho old one looked brand new, not even any wear on the big fiber gear. Lot said for frequent oil changes on a 150,000 mile car. My questions: 1) I used the tentioner with the double roller timing chain, should I have? 2) I replaced the oil pump with a high volume pump and see 60 psi at a t-fitting at the turbo but don't see any oil at the rockers. What did I do wrong?
Thanks, Bill

We don't use the tensioner, have seen the brackett break on the double roller chain.

On the oil pressure, if you are just cranking the pump, it will take a while to see any at the rockers, usually only dribble out. We crank the pump with a drill until the oil is flowing out of the rockers, but like I said, it may not be much. Once you run it, you'll see more. let me know..

Sorry for the delay in replying! Seems I didn't have enough patients in waiting for the oil to come up to the rockers. I did oil the rockers but didn’t wait long enough. (Lifters didn't tick but I was still nervous.) For the time being I’m going to leave the timing chain tensioner on.
Thnks,
Bill
