Freeze plug mess......

[woodscavenger]

So I had just painted my block and I noticed one plug with some corrosion which was leaking a bit. I popped it out and :eek: ! What a mess. It looked like someone had packed the hole with mud. By the end of the evening I had taken out the rest of the plug and dug a total of about 2 cups of crap out of the block. It was pretty amazing. I am going to flush the block. Maybe I just bought myself some engine cooling insurance.

It was amazing how much junk was in there.

How is your water distribution tube? Have you checked it?

Thus the suggestion posted in a recent thread that your engine would thank you if you pulled all the plugs and flushed out the block.

(I did not make that suggestion on the other thread but do agree with it.)

Distribution tube was actually in great shape. The problem with a flush now is how to do it and manage all of the water mess.........

If the motor is out of the car it's easy. Take it to local car wash and pressure wash any place you can put the nozzle such as where the freeze plugs, any water openings. If not and the motor is in the car just go pick up a motor flush kit. Attach it to your water line from the pump, hook up your hose and turn on the water. Not as much pressure compared to the car wash but works some times. By the way, if you use the car wash method dont wear anything you dont want to get dirty.

There are a couple or three welsh plugs on the rear of the block. You can not acces these unless the flywheel is off. If you have the block out of the car, it would be silly not to deal with these along with the more easilly seen ones. I believe one is aligned with the cam and not a water jacket but two do go into the coolant passages and should be addressed. The one fot the cam lines up directly with the cam location and is not exposed to the coolant flow.

Phil, that chili looks tasty.

That is the exact stuff that came out in torrents. Is it normal corrosion or is it as a friend suggested.......radiator stop leak fluid????

I remember as a kid my grandparents would talk about how people overheating on the road would go down to the nearest creek or river for water. From tin lizzies and up to high priced cars. All that silt does tend to accumilate over time. Noby gave it a thought exept cooling down engine and continue down the road.

that is normal block corrosion..the stop leak fluid per say..tends to find the radiator a better home to reside and plug up...as you can notice by the picture the impacted area behind the core plug..this large accumulation of sludge would great hinder the stop leak from ever reaching the hole in the plug..it would be too busy plugging up the small cracks and crevice of the impacted debris..
