So I was doing research on oil rings going bad they can either seize up or break. If they are seized do you think it's a terrible idea to fill every piston all the way to the top with seafoam and let it sit for a few days ( I will of course not start the car until on the cleaner is gone, and will change the oil before i start the car). Hydrolocking is the main concern of course, but should the seafoam completely dissolve after a few days of sitting?

Can't hydrolock if spark plugs aren't in.

 

Also no way will your plan fix an engine

If rings are seized it just might work? If they are snapped i would understand why it wouldnt

Having a similar problem with a 370Z I just acquired rather cheaply that was using a bit of oil on no1 and blowing smoke on start up and had high misfire count  on no1 as well as a result.  I had hoped that it was a valve stem seal and might be easy to fix but now don't think it is.  Compression is still pretty good so think that it is a gummed up oil ring ; as in my experience it is rare to break rings now days and the car had a very poor service history.  I soaked overnight in lucas oil additive and it did not do much and then tried overnight with Marvel Mystery oil and improved a bit and then tried a concoction of wynns, nulon and no name brand cleaners.  I could not find Seafoam here in Australia but the Nulon hinted at being similar. The top of piston and inside seems pretty clean now when I put a bore scope down the plug hole but sadly problem has not disappeared but has improved somewhat.  I was doing an oil and filter change after each of these treatments along with an engine flush.  Am just going to drive a bit for now with no more engine flushes and try some valve/ engine stop leak /additives and drive it for a bit and see what happens.
