Why is it that out of all the freeze plugs on this motor, Mine had to rot out the one between the engine and trans??? Who is this Murphy guy and why are we bound by his law?




This doesn't look good..




She should've blown a long time ago..



But the Knucklehead previous owner put several bottles of "Mechanic in a Can" in there.

 

And on top of all that, Papa Smurf broke into my garage and had his way with my block!




Oh well, Something something lemons, something lemonade, Or something like that.


Cloyes double roller

Ebay belly pan. $65 shipped and really good fitment.


Ready to go back in:


New water pump, painted timing cover

Cleaned and painted intake

 

I trust you flushed the rust and sand out of the block when you replaced the expansion plugs. Murphy is a President of the Automotive Parts and Labor Consortium. He also started as the engineer that designs windshield wiper attachments for different vehicles. (He doesn't like people.)

 

Oh yeah, I flushed it, blew it out with air, reached in there with picks to knock that junk loose then sanded the openings before flushing it out again and popping the brass ones in.

What's strange is that I have flushed this motor twice while it was in the truck and nothing like that gunk came out. I'm convinced that my first flush knocked some of it loose though because it started leaking shortly after.

 

The anti-freeze portion of your coolant never goes away. The anti-corrosion portion fades after 3-5 years. Flushing gets the old coolant out and puts fresh in.Your expansion plugs were probably ready to leak for some time and when you got some crud out, it was plugging the holes. The garbage you got out has been in there since the block was cast. The castings go on a shake table to vibrate the sand out. If coolant flows okay, that's good enough. To keep costs down, they don't do more than they have to when building the engine. When I raced, we used to use Liquid Fire drain cleaner. We found out NOT to use that on an aluminum black.

 

So True and most flush in a can are worthless waste of money.

 

Thank the EPA for that....... The 'good stuff' got regulated out of existence.

 

Huh, I never considered that it might be casting sand. When I took it out I grabbed a handful and it felt squishy like wood pulp, but after it dried out it is very finely ground and almost powdery. I just figured that was what is in those cans of stop leak. Also the rings in this picture were around every plug that I replaced. It is like a dried epoxy almost, but very brittle.

 

The powder is a combination of casting sand and rust. The hard curves are rust and chemicals from weak anti-freeze. You may find the engine cooling system is more efficient now after the repairs.

 

I hope so.. I put in a 3 row all aluminum radiator and a new trans cooler that is double the size of the old one.












I have taken it on a few shakedown runs so far and it seems to get up to 190 a lot faster now, but it has stayed there once it arrived, even when sitting at idle. It used to take a while to get hot, then slowly creep up and overheat if I didn't get it moving.
