All that silicone has blocked the cranks oil galleries so there's no oil being flung up anymore to lubricant the piston/rings causing the scouring.

Re-ringed but never took out the ring ridges in the cylinders, from what I saw. Yup that would knock bad.

I had a Ford pick up I bought new and at 70,000 miles changed that fiber cam gear out to a steel one. That engine ran for 350,000 miles.

If it were actually rebuilt, there would still be hone marks in the cylinders after only 10 miles.

@@janofb Theres cloth in there ,its a little bit like fiberglass cloth and resin ,but the resin is plastic. Kinda neat stuff ,and considering what its doing here its fairly strong and can dampen noise. Alas, the bad thing is it can break apart without warning, and the older it is the chances go up.

Those piston crowns look like more then 10 miles...far more. Or it sat idling for a LONG time...And coupled with the silicone and timing gear bits, the engine oil starved even at idle. I'm guessing you or I would have just heard it running and panic shutdown...The sounds this poor old girl must have been making. quiet but audible, ticka ticka click click, top end. Ticka tick clunk slap... >>> Panic HOW MANY MILES???? 😱💸money sounds. - Old tool and die maker/ offroad engine builder 🤑

Gear to gear not this new timing belt, or chain crap that was engineered to fail. I do have to say my mopar timing chains were never a problem.

@UQRXD Many 1972s had them too. I have had them get so loose that the chain would slap the timing cover on a BB. However, I will concede that oddly enough, even with all the plastic teeth gone, I never saw one actually skip time. But they were CLOSE and way out of time. You never could buy a new set with plastic teeth. All HP and HD motors had steel. I simply can not understand some guys putting a $1500 belt conversion on an HP V8 and then trying to account for several degrees of belt stretch! All my HP builds get a Milodon single idler gear drive. If it doesn't make enough power to turn those gears, I've got bigger problems! I have had one for 35 years on three different big blocks with up to .640 lift daily drivers, with around 300,000 miles on it with no measurable increase in backlash. I'm putting one on my 572 KB hemi, plus I can drive the MFI fuel injection pump off of it and change cams and timing without pulling the cover. I have seen good double roller chains loosen up considerably after only 20k miles. Web chains are stronger, and that's why transfer cases use them. An even greater mopar screw up was the early 60s plastic water pump Impeller that eventually spun on the shaft. And let us mopar guys NEVER forget the brain hook on the hood! Nobody's perfect! Have a great day!

I could never really understand why Ford, and indeed other manufacturers persisted with the use of fibre timing wheels when they are known to fail. A bit like the modern problem with eco engines using wet timing belts, crazy. This engine seemed doomed to fail, obviously NOT built by an expert. As a (now retired) workshop foreman, I banned the use of silicone ‘instant gasket’ as soon as it was introduced here in England in the seventies, primarily because I could see the damage it could cause. As the gentleman said, it squeezes out in both directions and I’ve seen the result of it being swallowed up by the oil pump and blocking vital oil galleries, total disaster. Also seeing the stuff oozing all over an engine smacks of amateurish incompetence.

Not nylon but fibre. I suspect that gear was very old stock. Many old new NOS parts are no good with age. Fibre gears,, I have seen them fail in a short period yet they lasted a 100000 miles 60 years ago. Gaskets that have either shrunk or simply do not seal anymore. I have seen rings that will not seal, machining was good, pistons were good, gaps were ok but the motor fumed badly. New OEM style and it stopped fuming. With timing gears many were replced by alloy ones. On race engines we pressed the gear off and onto new cams. Alloy gears these days fail in a few hundred miles sometimes. Not made to anywhere near the same quality. Many OEM timing chain sets used nylon gears on a steel ring. Yes they failed at 100000 miles and the chains were stretched big time as well. Now they are all steel gears but last less time. Even proper performance chains and gear sets fail. Silastic?? All these old engines require it. Everything is bent rested and warped. I do agree there was too much but you assemble that engine dry and it will spray oil everywhere.
