Enough for two cars was $1.23.

To what do you attach the end of the chain? And what keeps the chain from contacting the timing gears or generator gears?

To what do you attach the end of the chain?

It's fastened to the long bolt that holds the timer case spring. You have to keep the chain too short to reach the timing gear.

I have a entire box of that stuff

Have folks really had their oil fill caps fall out due to vibration? Mine seems to stay in place firmly.

I lost the cap to my cap... The sleeve stayed in the filler neck, but the cap that was attached , disappeared. .

Why Steve, Why ?.. in 53 years of T driving I’ve never lost an oil filler cap. They’re not supposed to “drop” in the filler forged part, they need to be compressed and held in by friction.

I have never lost one which was in place while driving. However, once I laid the cap on top of the hood sill while I put in oil and forgot it. The cap vibrated off somewhere while driving!

That’s a new accessory for me! Boy they must have made everything imaginable for T’s.
I thought by bending out the cap sleeve a little that was suppose to be enough. Seems like it is.

Years ago, I had a tired old engine I put in a model T that I was resurrecting from wreckage. It was the wrong year engine, but I needed to fit things around it as I rebuilt the original body and fit several accessories. It actually ran rather nice, except that I could drive the car all day long at 42 mph, with the engine temperature nice and cool. At 44 mph? It would reach a full boil in one mile! 43 mph would depend upon winds and ambient temperatures. Seriously, it was that consistent. The reason for boiling, was that the faster the car went, the more blow-by the engine had. When enough burning gasses went by the rings and worn cylinders, the heat was transferred inside the crankcase to the crankcase itself. Heat that normally went out the tailpipe instead heated the oil and block, hence the boiling. The other result of this, was increased pressure inside the crankcase.
I lost two oil filler caps by blowing them out driving too fast before I replaced that engine with the correct year engine I was working on for it.
And the caps both fit nice and tight.

Just a silly little side-tale.

Dang hot-rod kids. I don't understand this insane craving for speed. 25 per is good enough, and I ain't never lost no oil filler cap by burning up the road at no 42mph. Wayne, ya dang idjit, ya coulda kilt yerself !!

I too have lost one and was not driving all that fast with a somewhat fresh engine. I made somewhat the same thing for my gas cap using brass chain with a large T at the end. I have seen other cars with a chain on the oil breather cap, only mounted on the outside.

I've never had one vibrate out, but I've lost one by forgetting to put it back in. I have trouble finding a tool that was in my hand ten seconds ago, so losing an oil cap is easy.

Thank you for the suggestion Steve J! I may do that one some day if I have another T that seems to want to lose its cap.

I feel the need, the NEED for SPEEED! Rich B, with the proper engine in that car, and the wonderful "Universal" under/direct/over transmission, I got clocked at over 60 mph a few times! That was the old boat-tail with fenders and windshield (the wimp speedster! But I loved it). I had one speedster that I routinely drove at 70 mph on the highway, and another that I never ran full out because I really didn't want to get a speeding ticket. I clocked it at 80 mph once, and boy did it handle GREAT!

Rich B, I was clocked at 50 mph in the '15/'16 center-door sedan I had many years ago. But that was in the days when we could still buy real gasoline!

There is a reason I usually do not post in the "How fast should I drive my T" threads.

I knew someone that also clocked over 50 MPH in a bone stock with cast iron pistons in a center door. I have had my Huckster with the overhead to well over 50 on a long flat road, took most of it to get it up to that speed.

My 24 touring hits 50mph with no struggle at all on flat road. I hit 55 once....my dad was clocked at 62 !! I will pass on that, but am sure I could.
With 3:1 gears, much under 40mph, and it has trouble climbing a hill.

Haven't lost an oil cap yet.
Sure have found quite a few on the plastic "catch all" underneath modern cars.

Me 63 ,
more as 40mph with a model T scares me with a car with about NO brakes.
How do you stop that thing at 50 or more.
Do you have an anchor for emergency????

On my original brass caps, I use a finer link chain, and solder it to the cap.
