Hi All, I am a bit further and would like your idea regarding my hard to turn engine. It is a 263 of the last year. It was revised in 2008 and all this time I turned it over ( by hand) regularly. During the revision everything was done professionally with good new parts, by experience staff. Everything you expect was done. first oversize, skimming, new seats (leadfree), new rods. you name it.
I always found it hard to turn, but had no experience with 8 cyl,s ( I did a XK 6cyl once and that was easier.). But now, with new solenoid and fresh battery, it hardly turns!
What I know is this: My battery is only 570 CCA (which is low as 750 is advised). I used a 6 volt Optima in parallel, which made no difference. I also used a 12 Volt in parallel, but the jump cable was not adequate. I will repeat that with better cable and will source a 990 CCA battery.
Somebody (experienced restorer) suggested that the oil could be oxidized (?) which would made the engine turn difficult and should disappear quickly when it runs.
I tried to turn the engine using the starter one time before (couple of years back) and at that time it turned better, but not fast enough to start. I had a discussion here at the time, about how fast it should run. The idea then was to use a 12 volt in parallel (see above) or revise the starter to hi torque (3th field?), which I did not do ( yet).
Any advise would be welcome, but why is a basically fresh engine so difficult to turn ( BTW removing the spark plugs helps, but not enough). Can I do something? without immediately remove the engine?
Any Idea? Everything else is sort of done, so I want to try to start her up!!
Thanks in advance
en met hartelijke groeten en Blijf Gezond!!
