1960 Lincoln SAE 300 that is Frozen

admin

I have a Lincoln SAE-300 that is frozen stuck solid. I have used a mixture of diesel and acetone, PBblaster , and now I am using Kroil. This has not been a continuous effort as I only have weekends to work on it and it has been 4 or 5 weeks now.It is a Continental F244 engine that was frozen when I got it. The seller lives on a lake front property and his garage was a rock throw away from the lake. It had a top on it but no sides. He said he had it for 8 years.I have had the heads off now for a couple of weeks . Anyway is there a sure fire way to determine which pistons are stuck ? My mixtures will eventually drain out of all cylinders except one and very very slow on another. Could those be the main offenders ?Thankswxyoung
Reply:I have used a Hydraulic hand pump and diesel but does take time to work. I took a old spark plug and remove the guts and welded a 1/4" ips pipe the end then hook to hand pump. Then move from cylinder to cylinder watch the press max 200 psi. Did about once a day foe week then started moving Dave
