50,000 miles between oil changes, seeing is believing, Coates Engine Valve Train

[HysteryDiagnosis]

I hope this technology is both durable and in our future vehicles... potentially 50,000 miles between oil changes, most likely more.

1. There's one HUGE advantage to this kind of a valve train...

On an overhead cam "interference" engine, if the thing driving the camshaft breaks--this is usually a timing belt, unless you've got something like a Mercedes, a Saab pr a Porsche, all of which have timing chains--you're going to wind up bending valve stems, fucking up your head and, probably, putting holes in a few pistons. There are only three alternatives. One is to create a non-interference engine like Toyota does, but you don't make as much power as you could. The second is to use pneumatic valve actuators like they do on Formula 1 cars, but a Formula 1 cylinder head is worth more than your whole car. The third is something like Mr. Coates' rotary valve engine.

If they can work out any issues with things like not oiling the valvetrain, figure on seeing this industrywide in 10 years because people don't like to replace their engines if a $25 part breaks.

2. Higher compression rates.... ridiculous oil change intervals.... this tech could

be exactly what the naturopath ordered.

3. the ford overhead cam engines like I have in my f150 or our explorer

use chains and according to the manual they don't require any maintenance for the life of the engine. We have 150,000 miles on one and 132,000 miles on the other one. I know what you're talking about with the belts though as if you had an interference engine and the belt broke you were buying a new engine, junking the car or whatever so it is always smart to change the belt on a regular interval. Anything over 60,000 miles and you were taking a chance.

9. Be very careful with those chains

Mercedes, Saab and Porsche all were led to believe they could install timing chains and never worry about breakage. Overhead cam Oldsmobiles are the same way--and if you google "name of car" + "timing chain breakage" you will get a LOT of tales of woe. The problem is, the timing chain stretches, which chains all do. On something like a small-block Chevy, which has pushrods, you probably won't ever break a chain. V-8 Fords shouldn't break their OHC timing chains because those engines are pretty low-stress. If you have a Mercedes or a Saab you pretend it's got a timing belt in it and change them at the same interval.

4. Yeah yeah yeah. Where are they?

I've been seeing bullshit about those heads for 20 years now. No shit, pre-internet spam about Coates heads. I never see them. Never. No one has a set. No one is racing them. People are making reproduction Ford 427 SOHC heads. Rare? Yes! Wanna see them? Google and you cvan find build threads, dyno reports and race results from actual end users. Coates? Hot air and mystery.

The gearhead community is well aquainted with Coates. No reason to be exited about this at all. Vaporware.

6. They are on their way to the ME and China.

7. I guess they have new found suckers internationally.

5. The founder was arrested in 1994 for selling worthless stock on dubious claims

15+ years later not much has changed. Lots of hype, nothing of substance.
I will believe it when I see an independent third party verify it.

Then again they are publicly traded as a penny stock ($0.22 per share) so anyone who thinks Coates is the future of engines can plunk down their money.

8. I have a 1989 chevy astro, no oil change in 12 years. Still runs fine.

Gets low on oil,add more. Not worth the powder to blow it up, but it gets me to work and twice a year I add transmission fluid, brake fluid every few months (slow leak), and add oil 3 times a year.

10. You're funny. I take it you haven't seen the insides of your engine.
