Priming a rebuilt 348

[Victor A. Deming]

I've rebuilt several sbs and bbs, and used my priming tool and a drill. When I tried priming my fresh rebuilt 348 I only get oil coming from the rocker arm, pushrod holes on the left side. Is there a priming tool just for the 348s and 409s? Any suggestions would be appreciated!

Yes the priming tool is specific to the 348/409 engines. Show cars has them or you can get a truck distributor and make one out of it.

You do not have a priming problem!!!!!! You have a problem with the person that installed the rear cam bearing INCORRECTLY!!!!!!

Just to be on the safe side before you pull the engine to address the rear cam bearing get the right priming tool and try it again to eliminate that possibility first.

Get the right tool,rotate the engine some while priming,if no oil comes up at that time it's most likely the rear cam bearing that's either installed incorrectly or the wrong bearing was used.

Thank you so much I'll give Showcars a call on Monday. The motor is still on the engine stand, and I haven't installed the intake.The cam bearing where installed by a local speed shop that's been in business 50+ years.

Received the priming tool from Show Cars on Friday. Primed the 348 yesterday, well what-do-ya-know.....oil from the left and right rocker arm pushrod oil holes. Thanks guys, for the suggestions!

I've seen that problem before and rotated the distributor and turned the motor over and made it work, when I know that the rear bearing was right. Phil's point was well made cause that is often a problem when inexperienced shops put those motors together. Glad the tool worked. My old cut off distributer shaft works fine also!
