Have a noise that just began and think it is a starving valvetrain on right side. I remember seeing an external oiling kit available. ANYONE KNOW?? I think I would be in need of one!!! thanks---Bill

 

OH-YEA--this is a 56 272 yblock with 21,000 miles. thanks ...Bill

 

Bill:
What makes you so certain you have an oiling problem? The noise could mean the valve clearance just needs adjusting. The external oil kits show up on e-Pay fairly regularly, but in my opinion they are a stopgap fix, at best. Why not pull the valve cover and be certain? A barn find with 21k miles shouldn't be all sludged up.
Good luck

 

I've read that the external oilers can end up starving your bottom end. I'm not sure how true it is, but it's something to consider.

 

If an external oiler IS necessary, something is wrong and needs to be fixed, like too low oil pressure, used up rocker assembly, plugged oil passage from cam bearing to rockers, bad pump.

 

If the passage which feeds the rocker stand is plugged and not able to be opened without extensive disassemble there is really nothing wrong with external oilers. You can restrict the feed by using a restictive fitting. No more oil will be bled off the main oil gallery then would be as Ford designed it. The only thing that I can't see is the lad who wanted or did drill a hole in the valve cover to run the feed in. I would sooner set up one of the stand bolts which comes thru the cover and drill it and then make a high nut tapped 1/8 npt for the supply fitting. A little simple mechanics and you can fabricate your own oiler. Kotzy

 

I haven't worked on the 272 yet---but still thinking why did it start up all of a sudden,when it sounded so good for a year.? Bill

 

The real question is "What is it". Like RCA said it could be only adjustment. Then you can go through the list of other things. You will need to identify the problem.

 

`46 is right -LET'S get that valve cover off and check it out, possible problems
are, bent/ damaged push rod, rocker arm adjuster loose and backed out, rocker
arm bushings loose on shaft, plugged rocker arm , plugged shaft, rocker stand bolts loose, pushrod damaged by too long intake bolt, bad camshaft lobe. If no
oiling is present at the rocker shaft, then pull shaft and determine where the plug is. A Y Block can be started and ran with the rocker assembly off to check
for oil delivery from head passage. If no oil appears then the problem is Deeper!!
We need more INFO!!

I am going away this weekend to look at another truck--possibly buy!!! haha--wife thinks not!! I hope to know the problem this monday/tuesday.....you guys are the best!!! BILL

 

I have a mechanic buddy coming Monday and we will work on the noise and bleed my brakes again and he has a idea of how to install my supercharger on my yblock---hope it works.....Bill

 

OIL leak fixed at oil sump/but---still no word on my freaky noise ....I think valves need adjusting......maybe this week. Bill

 

Your camshaft might be going flat due to changes in motor oil

Here's something to know; motor oil makers have stopped adding and additive called ZDDP because it poisons catalytic converter.

ZDDP is needed in older engines. It's the high pressure lubricant needed for camshafts and lifters. You can buy it at WalMart. It's in STP oil treatment, and WalMart TechLube.

Don't add too much, it causes sludge. An ounce or two at oil changes and an ounce when you top up the oil level.

 

Why would an engine with solid lifters have wear problems due to the removal of zinc from the oil? With hydraulic lifters where no clearence for oil exists yes, solids where the cam has an unloaded period for lube no. Remember that type of valve train ran for years without additives in the engine oils. kotzy

 

So an ounce or two of STP is equivalent to the ZDDP content of 6 quarts of good diesel oil?
