Well, It's true.


If you lose your cat plug and start sounding like a log truck, An Autolite #48 Lawnmower plug fits that hole.

Now you need to add an injector and lawnmower coil so you can shoot flames out the tailpipe!

Would you call that an afterburner, like jets use or one hopped up catalytic converter!

"Now you need to add an injector and lawnmower coil so you can shoot flames out the tailpipe! "

Or just move the wire from plug 4 to plug 5 - maybe using that extra coil wire that comes in the set for coils on the opposite side of the motor.

"Extensive effort is being applied on a fresh approach to the problem"
We just hired three new guys; we'll let them kick it around for a while.

Just wanted to let you know I've also appreciated that commonality in thread size and pitch -- using a spark plug thread chaser on the sensor bung.

"Project slightly behind original schedule due to unforeseen difficulties"
We are working on something else.

I have noticed the oil drain plug is the same thread as the one on the inside of an oil filter.

I have wondered if that could use it to replace stripped oil pan threads. You know, weld it onto the bottom of the pan as a bung.

I would put the drain plug into the plate so it would align to the old hole. This would keep the filter plate threads round during welding too.

Of course, I would remove the larger area around the center to remove those "flow holes". That would be a hideous decoration but maybe and funny looking oil pan cooler! (:)

I do have a92 244 with stripped hole and currently using a butterfy type hole plug .That bothers me.Now you have me thinking maybe next oil change

Just be careful when welding a pan with ANY oil in it - vaporized oil is every bit as dangerous as vaporized gasoline.

Old timers know vaporized oil coming from a furnace as Gray Ghost. It is just like the vapor that arises when you spray charcoal lighter on hot charcoal.

I saw a horrendous photo of Air Force fighters who were cutting a cleaned 55 gallon oil drum with a K-14 saw. They had full gear and were uninjured by the fireball.

Good thinking! I never thought of any explosion.

Now that I think about it, I guess there could be some sizzling like in a fry pan.

Since I would try it with the oil drain plug installed, the whole affair would be contained in steel enclosed area like a barrel.

Get this, there is a vent available the FLAME TRAP! (:)

You know you got me thinking. Since I have a mig welder I could just circulate Argon or CO2 gas down through the oil filler cap port and it would escape out the flame trap or even vice-a-versa. Heck plug things and pull a slight vacuum.

A lot of work for thirty seconds of welding.
Just easier, if I stay careful and use my torque wrench first!

IIRC, the thread is 3/4-inch x 16 threads/inch. Possibly the only non-metric thread on the engine by the time production ended?

The proper nut shouldn't be hard to find in a decent hardware or nut&bolt shop, and easier to weld onto the pan than a cut up oil filter baseplate. Take the pan plug with you to confirm threads when you go shopping.

Yes I agree as it would be a heck of a junkyard repair! I just threw the idea around for fun as I have not done it.

A 3/4-16 jam nut will be harder to find. The base plate is already thin. Just a wee bit like a flying saucer if left whole.

Nothing a hand hacksaw and a sweating brow could not fix though! Hey, it's recycling, even the sweat!

Oh, I caught your post on the ported...ports. You are absolutely right back as far as where the LH systems began.

They used different pressure regulators than K-jet systems. I was remembering all my cars for those tiny holes. They were used for vacuum advance for the distributors 78 to 88, air bleed of for basic idle or maybe (?) even an air conditioning control valve. Over the years those holes around that throttle plate have gone to many things.
I like to think that they used that plate for the "whistle" effect at low engine (air) speeds.

My memory does not refresh as well as the F5 button. A glitch in my software! (:)
Thanks for the reminding me! (:(
