Hi, So I got my hands on a 7 bolt that's been sitting for 2+ years. It has intake and exhaust manifold attached on. Previous owner just said make sure to oil it up before starting it. It will be a 100 times easier to change the timing and water pump before dropping engine in. I tried to turn the crank to align tining marks but crank is completely jammed. After a day of soaking in pblaster, I finally was able to get the sparks out. Going along with an article i read, I have been adding WD 40 through the spark holes and pulleys for the past 2 days. But still nothing. I even tried to see if it would turn counter clockwise. Nothing. Please help! Any suggestions will be appreciated.
