The Stovebolt Site Forums The Shop Area Engine Shop Pics of a '54 261 engine with factory PCV

I thought some of you would like to see what a factory PCV setup looks like.

This is a '54 Chevy 261 engine. It came out of a 2-ton truck at the salvage yard. When I bought it I thought it was a 235 because it had the high position water pump. I assumed (wrongly) :o that the 261 had the lower and longer shaft water pump like the later 235's. Another weird thing about this engine, is that it has hydraulic lifters! I thought only passenger cars with automatic trannys had those. :confused:

The PCV valve sits on top of the elbow coming out the side of the breather tube. It's attached to a crossover pipe which goes across the valve cover to the intake manifold. There is also a tube running from the valve cover to the air cleaner. I've also included some pics of the casting date, casting number and the boss where the serial number used to be! Someone ground it off at some point?

hey holmwes what he heck you must be good with those serial numbers to put them out theree lik that I can't seem to match the ones up with my truck ? i got a 54 well thats what the id say's on the door jam H54K and so forth but the block has uhm uhm uhm where yours geos blank a F255X bmay be you can shed some lite.

what ever some one does its for the beytter or worst let em deal with it now and later.

I read somewhere that all Canadian 261's had hydraulic lifters and a factory predrilled 848 head.

Sure enough, this one does have the 848 head with the steam holes drilled out. I guess I need to go back to the salvage yard and check out the VIN tag. That should tell me if it is a Canadian truck, right?
