Update
Ended up pouring white vinegar down cylinder 5 & 6 in hopes op it freeing up rings .
White vinegar is nasty stuff !!!
I also purchased a bore scope to look in cylinder thru plug hole but my old eyes can’t see anyway so that wasn’t much help .
I hate to keep pouring stuff down cylinders if there’s a broken rod or something!
But of course I can’t see down in there.
There “appears” to be an inspection plate or something similar on passenger side of engine? Maybe not?
Anything else I can do other than patiently wait , to see if there is something broke in #5 or #6 cylinders?
I was advised not to remove pan so I havnt removed it .
I don’t wanna get too aggressive trying to free it up but jeeeeeeez !!!!
