Rick: Later cam cores are normally grooved... on your "disclaimer" as long as the animals were cats, it doesn't matter...

Rick:

If you don't mix up the pushrods or rocker arms, you can bolt the rockers back on and the adjustment will not change.  Also, some of the latest truck cams were crossdrilled, then replaced again with the grooved journal ones.  If your machinist came across one of those, your engine could have one.

Hi John,





I'm going to swing by the machine shop and ask him today if he used a cross drilled cam.



I don't remember what he used for the cam but it could very well be a newer one.



I'm pretty sure he didn't just regrind the old one.

I did all my test driving with the 239 V-8 that was in it.....It was VERY worn out!... I ran it until the timing set slipped and wouldn't hardly run.....That's when I obtained the 292 and had it rebuilt. It was bolted to a T98 and currently has a single speed Timken 6.80:1 rear axle in it! Nothing like low gears!! I have a 2 speed Eaton 5.83/8.11 rear that needs a ring and pinion.(anybody got gears?)

Ok,



Well I asked "Machine Shop Man" about it and he said that "Y-block cams have oil ports that only get oil when it's turning and we have to ensure that the cam bearings are lined-up correctly etc etc"



So it appears that he knows what he's talking about.........He also said that he probably just sent the cam out and had it reground. It's a 1960 engine that was rebuilt once many years ago. It's possible that it had a drilled cam in it I guess.



I'm assuming that I can just spin the pump with a drill and slowly turn the crank until I get a slight drop in pressure and see if I get oil on the left side or right.



Do the oil holes in the cam actually perfectly line up with the holes in the cam bearings every 180 degrees of cam rotation? I'm trying to visualize this. I'm assuming that I'll find that point and be able to pump oil to one side or other depending on where I stop turning the crank.





I guess I could just wait until I start it and see but I'd really like to know the rockers are oiling before I bolt the engine in. Maybe I'm just being WAY too perticular!

Did you ask him if the cam is grooved or drilled?

Have you verified that the rocker shafts are installed correctly? You don't have to remove them to check. I'd remove them only when you have determined that they are installed right and found out which cam it is.

Also, on Mummert's assembly errors page it is indicated that grooved vs. drilled bearings are different. Find out if the proper bearing were used for the cam.

Ok....alrighty then.





Well, I feel somewhat stupid......I do learn eventually though!







I removed the rocker assemblies and found that they are(were) in fact on correctly.



All I had to do is turn the engine a bit and turn the pump (at the same time) and I discovered a gusher! Turn it a little further and the gusher switched sides! Obviously I have a drilled cam.



I probably should have done that first but I needed to bottom out the valve cover studs anyway. They weren't screwed in all the way.





I also put a gage on it and was surprised that I could turn the pump slowly and get 50psi easily. Turned it fast and I got about 75 psi before it felt like the relief valve opened.



Much ado about nothing!



I apologize for wasting everyone's time!!



I would rather save my questions for the important stuff!!

Rick:

Glad to hear all is OK.  It has to be comforting to you to know that the machinist really knows his Y Blocks.  It is also gratifying to the guy who figured what was wrong, gave you an answer, and received verification that he was right.  Thanks for letting us know what you found.

Well I also had a little chat with John Mummert today too!



I wanted to tell him that the new Rams Horns I bought from him look absolutely beautiful with the flat black ceramic coating I had put on them! I also told him that I now have about the same amount in them that I saw an old rusty set go for on ebay several months ago!!



He said it best I think about possible upper oiling problems...... I could verify oiling now or I could do it when the engine in the truck. It would be somewhat harder to fix it in the truck if something was a'miss!!



So I'm glad I verified everything is working now while it's on an engine stand!



I really like to ensure everything works properly before bolting it in place!



I'm a little weird that way I guess!





Thanks again all!







John, I love that 57 in your sig. I owned one that my Grandmother bought new. I drove it all thru high school. It had a 292/Fordomatic in it. I wish I had kept it!

No time wasted.  You're just learning, as we all are.
