Back about 6 years ago I searched and found an interesting article about a big block camshaft oiler that was installed in the lifter valley and sprayed oil directly through the valley windows onto the camshaft and lifters. The company that marketed it was B.C. engineering. They tapped into the right lifter oil galley and then made a copper tubing spraybar to distribute the oil. It looks like a real nice piece and a good way to prevent camshaft/lifter failure that seems to be happening on a more regular basis in these engines. It works on the same principle that NASCAR engine builders are using with internal oiling in the valve covers to flood the valve springs with oil to cool them. I have not tried this set-up, but I think I will on my next engine. How about some discussion out there on this set-up, has anyone tried this work around before on a wet sump flat tappet big block? It's got to be better than just a splash oil system.

Lots of the boat guys used them...really helped low speed oiling. But I think most folks are going after the EDM holes in the lifters themselves these days to put oil right at the lifter/lobe juncture.

This one?

I think it's a great idea except for the extra windage it's gonna create.

Yes, that's the article. In my case, my engine won't be turning enough RPM's to worry about windage losses. IMHO I think it would work better than the EDM lifters, in that it would also cool the components involved similar to valve spring that multiple parts rubbing together. During the Camshaft break-in period, I think it would help eliminate cam failures especially for those that don't time their engines to fire immediately or have another problem that might rub off most of their moly lube during that critical period of time. It's got to be better than overfilling the crankcase with extra oil for additional splash during that time.

I can also see why the boat engine guys might like it. They are fighting constant power on with no "coast" and if they are racing, they have oil control issues with the acceleration part and water smoothness part depending on if its ocean racing or boat drag racing. Short term/long duration issues. Is there anyone or know anyone that's actually installed or are using one currently? Thanks is advance

These are the way to go.

The EDM'd lifters do the same thing without the problems of fabricating something additional into the block. If the spray system fails at any point you have the potential of losing a whole lot of oil pressure in an instant. Using EDM'd lifters keeps things simple and a whole lot less failure prone. Additionally the lifters are placing the oil EXACTLY where and when it is needed instead of simply throwing a lot of oil at the cam and hoping some of it ends up between the lobe and the lifter.

Well said :)

If it is hyd, have the lifter bores grooved while the engine is done.
As for "no coast" in a boat mentioned above, the cam does not care if you are on or off the throttle or not, it still sees the same loads at the cam weather under power or while crusin except for the higher forces imposed as rpm goes up.

Cooling,,, you want the oil directed at the highest pressure area to protect & cool & this is where the lifter meets the cam, as was stated above,,,
not by just squirting oil in the general area & hoping it gets where you intended it to go.:D

Rich, I installed one when I was building my engine with my new setup about 3 yrs ago. I had those Crane Pro series solid roller lifters installed at the time and was trying to get some additional oil to them.
My machinist was against it, basically saying what Wolfplace was saying on the message above. But I figured it wouldn’t hurt.
I got the kit off of eBay. I drilled and tapped where identified in the instructions. The copper tube has slits along the length. It sprays oil like a fan above all the lobes on the cam.

I think it was great a idea, before the EMD flat tappet lifters came in to play.
As for a roller application. My cranes died anyway, I think it just prolonged the cranes expiration time.
The funny thing is the lifter failed in the same place that my solid flat tappet lifter died after 3 1/2yrs of street strip use. In the right back corner of the block. I hear that is a common place for big blocks (lack of oil). Thanks to Wolfplace I am running some crowers with the HIPO Option, they matched my rockers(smile).

I have a Melling High Volume oil pump and 3/4 groove mains on the bottom end. I run castrol 20/50 now. I use to run straight 30w, all non synthetic (old school) but my old pressure was to high. Its down to about 75-80lbs cold (1500-2500 rpm), and warms up to about 30-65 lbs hot. That’s using the multigrade oil.

Hope this can be of the help to ya.

I bought one of those camshaft oilers and it's hanging from the pegboard behind my workbench. I decided I wanted the oil to go at the lifters and the camshaft contact point. It took alot of time sitting there with a 3 inch long piece of a wood ruler and rotating the cam and measuring to get the triangualation for the hole spread. I made mine with the holes offset from the centerline of the tube and the oil actually sprays out at the lifter and as the lifter goes up the oil sprays the bottom and the lobe. Last year when I was getting ready to take the motor out I pulled the intake and the spark plugs and put in my dummy distributor and had a friend turn the motor over with the starter while I ran the drill. For a street car I have no doubt that it helps. But if your worried about windage you don't want this in your motor. I was running Crower severe duty roller lifter with the hippo option. This year I'm putting in Isky Red Zones with the new 408 motor I'll be putting together and I'm putting in my oiler too.
It was hard to see the holes in the picture so I took a marker and tried to dot where they are. Here is a pix on my oiler.

Hi Everett,
Thanks for the plug but if you got the lifters from me they are Isky Red Zones, I don't sell Crowers,, :D

Nice heads,, :thumbsup:

Mike, Thanks for the shout out on the AFRs. At the time, they looked too good to install -).

I had to go back into my PM logs to look ya up on this one. Yep, you are right. You were the first one I contacted in getting those Iskys Red Zones, after those Cranes failed on me and were a great help with the pricing.
After seeing all my grief, the (War Department) ended up surprising me with some crowers a few weeks later, no question asked (U never know women)
No complaints about that.

You are still da man to deal with
