Howdy all,
Well I've been watching this site for quite some time but never had anything to say until today!
I had my 1960 292 rebuilt by a local machine shop last winter in preparation of putting it in my 55 F-600.
I pretty much watched most of the process except the final assembly (big mistake probably)
I decided to do a little work on it and wanted to "spin" the oil pump to prime it and check oil n the top end.
Well, no oil in the top end!
I am hoping that the rocker tubes are just "turned" or something simple like that and not the block/heads are plugged or the camshaft bearings are not aligned with the holes etc.
Anyone with other ideas? I think the guy would make it good. I toyed with the idea of giving him a copy of Mummerts list of "mistakes" but didn't want to insult him (older guy)
Thanks

Rick,
If your 292 has drilled cam journals (not grooved), the oil pump won't feed the top end unless the holes/cam are aligned. Slowly turn the motor over by hand while driving the pump and watch the rocker drain.

Is it pumping at all?
The rocker shafts could be assembled so that the holes are not lining up correctly. When standing in front of the truck, looking at the engine, the shaft drain tube should be at the rear of the right head and the front of the left head.

Thanks for the quick reply!
I hadn't thought of that at all!
I cannot remember where the cam came from. (I believe he told me it was a new one) I did tell him that the engine IS a 60 model so I'm assuming that he would have gotten a cam for the newer engines.
The newer cams are drilled and the older ones grooved??
I hope so. I really don't want to have this guy tear it down  (even if he will!)
My eventual plan is to mate this engine up to an E4OD in the truck using a Bentsen adapter.
The machine shop guy also did a little intake porting and balanced the rotating mass.
I also have a set of (ceramic coated) Mummerts Rams Horns on it.....They are Beautiful!
I'll try turning the engine and I'll check the orientation of the rocker tubes.

I don't mean to offend, but did you spin the pump clockwise or counter clockwise?
|
|
By HT32BSX115 - 18 Years Ago

No offense taken 
That would've been my first question too because initially I did spin it the wrong way (clockwise!!)
I couldn't remember which way it was supposed to go.....it did pump oil CCW because I found out how loose the oil filter was when it spewed oil out at the oil filter base!!
I was able to pump oil just using a hand crank type 1/4 drive speed wrench. I didn't put a gage on it but I think it was pumping pretty good. It was very hard to tun CCW and it felt like it was producing a fair amount of pressure.. I had to tighten the filter another half turn to get it to stop leaking.

Pull the rocker arm assemblies to make sure the holes in the shaft matches the hole in the head. If not that is your problem. They can be put on wrong. While you have them off, spin the pump with a drill (counterclock wise) to see if oil come up in the hole in the head. If you don't get oil then, it may be the bearing.
Did you have a cross drilled cam? If so, try turning the motor over a little and then turn the oil pump with the drill.
You can test the oil pump by setting up a mechanical oil gauge and spin the pump.

Ok,
You'll have to excuse my ignorance!
Are you saying that because of the way the cam is drilled(if it's drilled), I can move the crank in small increments and find the point where oil will flow up thru the
block and heads to the rockers? (presumably each side gets a shot of oil at a different position of the crank?)
I'll give that a try. I suppose it's possible that both rocker shafts are installed wrong. I didn't do it. I allowed the machine shop guy that was supposed to know what he's doing do the job.
I guess I should have given him the Mummert list of possible assembly errors!

Before you do any damage why not call " the guy who did it "and ask him if he was aware of the rocker shaft oil holes and if he assembled it right. BEFORE you mess it up.

I would think that removing the rocker shafts wouldn't cause damage. I know I'll have to readjust the valves but I would want to check the adjustment anyway.
I was going to try turning the crank a little at a time and turn the pump to see if I can get oil to flow out of the supply port on each side.

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. John John

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. John

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!

I'm allergic to cats, but the stray torti who adopted me (after I made the mistake of feeding her!) doesn't seem to bother me.
I guess (from what I've heard) if you park a REALLY nice car outside down in Fla., shooting cats could become a tempting hobby.

Have you seen the bumper sticker; "Missing your cat, look under my wheels" I think our big,not fat just big 15lb ginger tom might take a different view on the matter.
