I agree that the opti is most likely the problem . water is a killer to these. some of you down in texas got some flooding rains lately. you drive this is deep puddles it is N/G..

The other issue is the plugs being fouled, and this excess fuel getting into the crankcase.

remove clean dry out OPTI , clean and/or replace plugs. then with the water pump off see if it runs for a few seconds. then put it back and if it works out change the oil.

if you see any oil leaking behind opti replace the seals felpro front cover seal kit.

Not difficult at all with the Goldmaster video series. All the cool kids are watching. :)
