84' Block Heater Issue

My neighbours got an 84' F250 with a 6.9l and an C6 he is looking at getting rid off.

Remember reading about a issue on the block heater on the 83' and 84' a while back.

The truck looks fine, not leaks, etcc...

Was the block heater issue a common thing with all these trucks or was it a certain production run that had problems.

Is it only a problem if you actually use the block heater or will the leak develop over time.

What were the problems?

I am looking to add this beauty to my collection if he will part with it.

From what I have been told, the block heater causes problems when it was used. What it reportedly did was cause the block to crack only when used, so if he never used it, then there should be no problems.

That is the way I understood it, thanks.

The truck is a westcoast truck so the blockheater was never used so it should be ok. I guess the first thing to do would be to cut the plug off so it does not get accidentally plugged in.

I have owned a 1984 F-250 with 6.9L since May 1994. The original engine was otherwise very good, but had to be replaced in December 1996 due to cracked block behind the starter, by the block heater. This has also been a west coast truck all it's life. I bought the replacement engine from IH, and to my amazement, they gave me $1075 core return credit for the cracked engine!

You get lucky some times I guess. I doubt that the crank, rods, heads, and intake are worth $1075.
