Ford 302 spark plugs

[jhande]

The engine is still under warranty, if OP goes pulling heads off, engine builder can rightly refuse warranty. Best thing is to just package it all up and send it back.

Chris.....

I've been in the automotive field all my life and understand all to well how warranties work. The point I was trying to make was without pulling the heads and/or oil pan one won't know what happened.
I'm still leaning towards a blown rod.
Personally I wouldn't be trying to figure out why or what is causing the problem, straight back for warranty coverage. But then again, I would have rebuilt my own motor as usual.

I'm hauling boat there Friday and there going to pick engine out...I also thought of being there when the checked it out.

Update....engine builder seems a bit baffled as to how it just stopped with no prelude to the problem. He looked at all my pictures and in the spark plug and exhaist Manny holes...checked plugs...he says it all looks normal...it's coming apart Tuesday with me there

Well here's the update after being at machine shop

Is that a smashed bearing?

 

[Jakem]

It a small piece of something that was jammed up until we flipped engine over and then it spun freely as it should...and that fell out. Not sure we're it came from or why but they figure it looks like the nit that holds the aircleaner stud...they are eating the labour on piston and head and intake re and re...I am paying about 200 for new gaskets and we carry on

Ayuh,..... When that nut is dropped down the carb throat, that's where they end up,....

Arrgh every mechanic's nightmare!

 

[Jakem]

Well it could gave been way worse..paying 200 bucks for gaskets is fine with me lol...

 

[nola mike]

Seems reasonable.... I can't remember the last time I had that nut installed on the spark arrestor

 

[Jakem]

There isn't one now so it won't happen again that's for sure

 

[Lou C]

When I pull the carb off for a rebuild always tape a piece of cardboard over the gasket on the intake!

Ayuh,..... Autolite IS a Ford plug,.....

Donno the heat range,...... Run 'em, 'n check their colors,....

Motorcraft is a Ford plug. Autolite was until 1969? Autolite is now under the Fram unbrella.
