F20 oiling idea

Andrew Psencik · Mar 18, 2013

I just came up with an idea that might or might not work. What If an able bodied individual, such as myself, plumbed a line from the return side of the filter to the vlave train so it would recieve constant lubrication?
Prehaps the pump does not have enough pressure to lube them. Ive been told it only runs about 5 psi.

Just a thought.

Great idea! Decades late. At least 2 of my F-20s have this system.

Dang. I thought I was being smart. Where was I in 1932 when they were building these things.

If you do I highly recommend a shutoff and just turn it on for a bit otherwise the slightest valve cover leak makes a huge mess.

With all due respect, I would not bother. The original oiling design works just fine. Just squirt some oil through the flip up caps on the valve cover at the beginning of each day's work. The trays hold the oil and the felt wicks allow the oil to slowly drip on each rocker arm.

food for thought

when you dump too much oil in the felt trays where does it go??

yup, the valve train is a 'total loss' oiling system. the excess will run down into the pushrod galleys and then it drains out the back of the block out of that little 3/8 NPT elbow. You do this and you will eventually run your bottom end out of oil then you'll be up s*^# creek without a paddle

As Kirk mentioned, the original system is more than adequate. If you want for your own good nights sleep, get a few more pieces of felt and lay in there to hold a little more oil

I thought it drained back into the oil pan....... That's why you
are supposed to drain it every so many running hours. Guess I
need to do more homework on these old machines. Glad I
didn't do it then.

some of it will, if it runs all the way down the pushrod and pools in the top of the lifter it will seep back down into th ebottom end. most of it runs out

i lubed the crap out of my W-30 way back in the day and i just watched it run out of that pipe on the back right down the side of the block

As me graqndpappy used to say...those were the days when oil was cheap and soap was plentiful.

Seriously, and old IHC engineer said they did the valve train that way as it was prone to a build-up of condensate (water) and they wanted to get rid of the water so it didn't get into the oil-pan.

you drain the pet cocks on oil pan, because the distillate would contaminate the oil by going past the rings from not burning it due to not being run hot enough.
just do what ihc designed to do, you dont need a lot of oil on upper valve components.

Just to add to the discussion.
Dad had a 31 Regular & 29 10-20. Both had dealer installed kits to do just what you are talking about. Excess oil runs down past pushrods, into the lifter galley,& back to the pan. Both kits were installed somewhere around 1950.
That pipe at rear of block is just a vent. Modern systems run the fumes/smoke back through the intake to be burned instead of just dumped into the air. If oil runs out there, the internal drain passages are plugged up or rings are so worn that there is excess blowby.
The 3 petcocks- if oil dripped from the top one pan is full. If it drips out of second petcock, okay to run. If running distillate would drain to lower petcock & refill to top one. This was to drain off the unburned fuel that worked its way past the rings. Forgot the number of hours this was recommemded. If running gas it wasn't required.

30 years ago I bought a 22-36 from a farmer who had retired. He had put a similar oiling system on it with a petcock to turn it off & on. He said he just opened the petcock for a few seconds to oil the valves and then closed it after starting it. I had it for 20+ years and then sold it back to his grandson who wanted it back. Al
