If you have access to an oscilloscope you can check for excess slack in the timing chain with that. That won’t tell you if you have gear about to fail, however.

Is the vacuum advance working? Not that it would cause your issue. Remember this though. As the timing chain stretches over time, the camshaft timing becomes more retarded. So more ignition timing may be needed to compensate for that.

What about wear in the distributor shaft bushings. With the cap and rotor off try wiggling the shaft to the front and rear and left and right. It should only have .002" clearance. Hardly enough to feel. If the bushings are worn, the shaft can flop around causing timing to jump around.

Chain guide? No such thing or reason to have a “Chain guide.” I like the double roller with the Magnum timing chain tensioner.

I put the tensioner on my 340. I had to replace the timing cover. At 21K miles I checked the pads on the tensioner. No wear at all. This was with a Cloyes True Roller chain. That surprised me. I thought there would be some wear with the double roller chain.

I’m looking for the bolt with a hole that holds on the cam thrust plate and also the piece of metal that drips oil on the timing chain. Thanks jesse

You don't need both. One or the other, bolt or oiling tab. Or you can just drill a .040 hole in the thrust plate.

Maybe from the retarded cam timing?

I bought a 225 not long ago with a hole in the timing chain cover because the sloppy chain wore through it.

Took the top end off.. Has 360 heads on it Comp Cam 10-268H Sloppy double roller Timing chain.. Pistons are Flat tops and at tdc are 0.0852 in the whole

Now your story begins. I strongly suggest you replace the timing chain.

So I have had my Duster running for about a year now and it seems to run fine. It idles smoothly and I can drive it anywhere. I is a 2012. 5.7 hemi truck engine that is mostly stock except for a 392 cam and Mopar springs and a mega squirt gold box. But it doesn't seem to have the power it should...

I never noticed a plastic timing gear in my boredom searching I've done so that a new one for me

In Garys motor? you can see the whole damn chain in the first few seconds.... and most of it in the thumbnail... wtf

I can't think of a single Chrysler engine that has pressurized oil to the timing chain. IMO, that's why the chains stretch really quickly. They don't get the amount of oil they need to keep them cool and lubed. I said lubed.

Timing chain. I had the same issue after about 25-30 hours on my motor. Changed out the Cloyes true roller to a Pro Gear from Hughes. The issue went away.

yeah, if it wasn't rebuilt only 1000 miles ago i would have said timing chain stretched and jumped teeth. easiest check for stretch is to turn the crank back and forth at the pulley bolt while watching how far it moves each way before then rotor arm moves. it shouldn't move very far at all. neil.

...for the heck of it. It was placed in-between a rock and a had place Like the valve was open at the wrong time and the piston hit it. (Timing chain, stuck lifter in the up position, valve stuck closed and the cam and lifter tried to open it) I guess a lifter could have pumped up But most...

Why would the damper move at all? You’re moving the camshaft in relation to the crank. Edit- Got it. It appears you’ve figured out that your test proved you installed the cam retarded.

...rotor included, and just checked point gap again, setting it to .018. I put on a new coil and new wires. I thought I had diagnosed a timing chain with weak stretch, as it had all around low compression (106-122 psi) and varying spark timing. I read of a way to test chain stretch without...

I picked up the sweetest old lady owned, garage kept 5th ave once for $200. She parked it in her garage and would not start, so she bought a new car. Yup timing chain went out, it had about 85K miles on it. We used it for a family car for years, kids called it "the old comphy couch"

...cap off to see that the rotor is turning when cranking it over. Start with the basics. Rock the crank back and forth and watch the rotor to see how loose your timing chain is. Possibly the chain jumped a few teeth if it is loose enough, throwing the mechanical timing out of whack. ☆☆☆☆☆

BTW.. '67 coronet was my very first car... slant 6.. got it for free and put in a $11 timing chain and drove the piss outa it :)

That's what I have been doing for many years now. True roller, with key ways to degree cam, and magnum tensioner

before installing timing chain, soak it in a can of engine oil, for half a day, then install, it. chain will last longer. old motorcycle trick. just food for thought.

...minor or is corrected sometimes. I don't agree with everything he says, so most of it is entertainment to me. Second, He never said the timing chain broke. Third, he said that he could be wrong and it's just his assumption of what may have happened, which was the timing chain being too...

Not sure if you remember Uncle Tony showcased this in a video saying the timing chain broke...his nut swingers ate it up...

That's there Rocket Surgery

Damn that looks complicated.

I have had my Rollmaster in for 3 years, have the engine out now, timing chain is still tight.
