I'd like to see some feed back on this as well, I fitted up a scat with them for a club member a few weeks ago and another to do as well, making it clear that the supply vendors only recommend to use with a oil pump.
Chev have had replacement dipper rods with shells for years, the 6 cyl is far more HP and revs than a T, so should they fail in a T??

Up until the 50's the 6 cylinder, Chevrolet used poured Babbitt rods with inserts on the mains only.

John,

Running insert bearings with splash lubrication and SCAT stroker with Snyder's forged insert bearing rods in my '26 TT. Currently, 8000 plus miles on the TT.

I would say if you are going through all of it, Scat and insert rod bearings, I would just run pressure to them

John, I have a lot of experience with the Chevy 216 and insert rod bearings and the stock ones. It still uses a low pressure oil pump.The biggest problem on the 216 is to get the oil spray pipes targeted correctly to spray oil at the dipper. I had to borrow a targeting tool and never found one for sale. With the Model T engine and inserts if you don't use a oil pump you won't get enough oil flow for the inserts. If you use a pump you might as well drill the crank for pressure to the rods fed from the mains, it's not worth pluming for rod spray like a Chevy 216.

Kevin,
Do you know how many degrees of the crank rotation the oil spray set up would hit it's target of the dipper? would it be more than the oil dip of a T ?

Frank, I don't know the target info in crank deg's of rotation, the spray hits the dipper a little before BDC above the dip tray that fills with oil, and would hit the bottom of the rod a little after it leaves the dip tray. The targeting left or right is the more important than up or down a little off so that the dip tray fills with oil on the rods up stroke.

My new rebuilt model A engine for my race car runs insert bearings mains and rods. It still has the original oil system. Main bearings are just offered oil from the valve galley and rods still just get oil from the dip trays. I have talked to an owner that has five engines from the same builder with no trouble and highest mile engine at 61,000 miles. The builder is Ron Kelley Designs, he has had many engines in the great race with great success. He doesn’t recommend drilling the crank because it will cause them to break. So I guess I am saying they should work well.

Good thing I didn’t know that drilling A cranks causes them to break. Otherwise I wouldn’t have been able to drive for many thousands of miles with a engine that can easily rev to 4500 rpm!! I will just keep doing them I think!!

If you must run inserts in a splash oil system make sure to change the oil often. The insert bearings are steel shells with a relatively thin bearing material as opposed to a poured Babbitt bearing. The crud in the oil will be harder on the thin bearing with out the flow, and hopefully filtered, oil in a pressure system.

Hi John. It’s been a while. I am running those insert bearings and a scat stroked crank and the splash oil system for over 4 years now with no complaints. If I was to do it again I would go with the stock stroke scat crank. The stroker crank just had no advantage. Also I’ll mention the metal timing gears I used work great but are noisy.

Hi Scott,
yes it has . How many miles have you logged since the installation?

Insert bearings really like filtered oil. So the guys running them on splash should change the oil quite frequently.

Our first home grown Ford 1960, had a spin on oil filter but our first GM's 1948, no filter until 1963.
Those, what we called grey engines in the GM holden 48 to 1962 were still well known for 100'000 miles + and some with out to regular oil changes, no speed limits back then either. Steel- copper backed babbitt slip in bearings.

Called Snyders about these rods. While they have some existing stock in undersized inserts, they are sold out of "standard" sized inserts. And they reported that they don't plan on making any more.

Called a few dealers that sold them, Langs, Macs, and since they were such slow sellers they don't stock them. So it looks like no more rods with standard inserts, and no replacement standard inserts.

It’s hard to say how many miles. I was driving it every day but just around town. Maybe 15 miles or less per day. Last November I got sick and I’m just now getting out again. So maybe 2k to 3k average per year for the past 4 years.

Check with Scat. Last week I spoke with Tom and he said they have made a standard Model T rods that use an insert or can be Babbitted
Now an opinion, our T engine is very dirty and running inserts without filtered oil is asking for problems. Yes it is done but many have failed

I'm not trying to hijack the thread here, but since the SCAT rods were mentioned.....

I have a set of the SCAT rods made for babbit still new in the box, I don't have an engine to put them in. I'd sell them if you are interested.

I had considered using the Scat babbitt rods, but the few guys that I called about pouring babbitt in them and then fitting them to my crank quoted me $850++ and booked into 2020.

Frankly, I'd prefer using a floating pin style rod with a modern piston.

Eric Barrett,
21 milloin VW aircooled Beetles were built with inser bearings and no oil filter. Can't be too bad, methinks.

Roar, yes, the VW ran with inserts and without a filter, but they didn't have transmission bands or any cast iron components doing their part to contaminate the oil.

That said, I'd still run inserts if they were available. With the limited use the car would see, oil changes every 500-700 miles aren't unreasonable.
