Rikki, anything is possible, but I've never seen a lifter bore go out of round on the Packard. Look carefully at the rocker arm pushrod seat and the pushrod itself. I've seen some of them wear enough so the pushrod end would be captured by the rocker.

thanks jack I will,, did not think about that,,,

thanks

as hot as it got, yap, it might of galled the push rod seat, I cleaned all them, but did not really inspect them,

thanks jack

We have refill the engine with 20 W 50 oil.

Now, the noise comes when the engine is cold, then it goes away ... for 10 minutes. Then noise again ...

Is the Oldsmobile oil pump the only solution or is it an other ?
I we change the hydraulic tappets ?

I plan to revolve it in 2016.
Could not stay as is.

The engine has been restored less than 10 years ago.

I sold over 60 Olds oil pump adapter kits before I turned production and sales of it over to Jack Vines. I had 100% satisfaction (a lot of feedback) in correcting low oil pressure and severe tappet noise problems.

It's not an expensive solution either compared to new tappets or an engine overhaul -- once you get the oil pan off (itself a PITA).
