Siezed 273 v/8

alcronk said

I have just bought a 1964 valiant siget 200 273 v/8 pushbutton auto .The car was stored inside for about 15 years . IT was running when it was parked .But it will not turn over . We have tried putting diesel down the spark plug holes and waited for a few days but we could not get it to move. There are many products on the market like engine release but at $20.00 per kit, per cylinder, plus $5.00 per kit for shipping . Looking for any info on this product or any other ideas that members may have used to try and unsieze a motor. Any help would be welcomed. Just trying to get it running without tearing it apart. Would like to try to keep stock. Thanks in advance for your time and knowledge, Thanks Valiant64

Hi alcronk,

Cool sounding car. Would love to see some pics!
I'm not a professional mechanic but I dabble.
Some members here have mentioned a product called "Sea Foam" with good results. I haven't tried yet but is on my things to try before I die list! LOL!
From all the rusty stuff I have had to break loose (never can afford new and wouldn't want new anyway) I have had excellent results from a product called "Aero Kroil", but have never used on cylinders/rings sieze. (knowing me though I probibly would try this due to excellent results in other applications with bolt/nuts)
I have made a copy of this product (Not same formula I'm sure) of 50% each of ATF & Kerosene. This solution eats rust like nobodys business. I have cleaned the rockers on my 64 with kero & ATF before with excellent results.
I'm sure when most of the FABO membership wakes up later and checks yor thread, you'll have alot better advise than mine!
Good Luck, sounds like a really cool car! Post some pics please!
