Follow up on the hole in the piston and piston melting. After some reading, I think the damage was from pre-ignition.

Yes - I have found other 440's with the EGR still mounted on the intake manifold but no hose coming off of it. This engine was a 1976 440-3. I also have a 1977 440-2 that has so much more "stuff" on the intake manifold. Vacuum hoses all over and many that I follow to find they are not hooked...

Hey Lefty71 the help tech at SMP thought that with mounting add-ons, a delay could be possible. No direct evidence tho. Thanks for the comment. But now with the PS-16 part, that I didn't know about until pnora's reply I won't have those add-ons. Great idea to remove nylon line, thanks for...

Replacement of the two sensors on the rear of a Mopar 440 block (1976). Replacement parts from Standard Motor Parts (SMP) do not fit. The oil pressure sending unit SMP PS-59 is bigger and longer than the original. It will not line up with the hole. Do Not Buy. Best advice I was given...

"Yours is broken" yup need that as a bumper sticker. They are both temp gages. I heard the capillary tube one is more reliable? Why two temp gages so close to each other? It not before and after the thermostat. Thanks for the info. I really should by the service manual.

I honestly do not know what happened. PCV rattled in its casing so its not that. I know I sealed this engine tight. I used Permatex form a gasket everywhere. With 1000 miles of break in the vacuum gage showed strong vacuum (15-20). The blanking plate for the EGR has black exhaust gas where...

I plugged the EGR on a 1976 440-3 and blew up the engine. 1st pix is of the blanking plate removed with black gas having blown past gasket and second is the EGR being put back on. Dented Valley Pan pixs shows what the over pressure did. And finally, the hole in the new KB piston. This was...

The Permatex form a gasket sealed up the valley pan and the intake manifold and the valve covers making a very very gas tight engine.

I pulled two other sending units that have never been hooked up also. Which one is the temperature sending unit that hooks to a gage and which one goes to the temperature warning light?

Thanks !!

1976 440-3 So the bell-shaped unit is an oil pressure gage that hooks to a gage. What does the unit next to it on the passenger side do? Is it a pressure warning light sending unit? Or is an oil temp sending unit that would go to a gage?
