Cat30 Exhaust riser blew up - Engine won''''t start
If the engine has ''frozen'' because the piston rings have rusted to the cylinder walls and piston grooves, don''t despair ... do the Marvel Mystery Oil soak (plus a little "PB Blaster" mechanic''s rust penetrating catalyst - auto shop sutff) as outlined in my previous post .... and keep on attempting to break the engine free with your hand crank.... it WILL free up and will probably run just fine. Once it frees-up turn it over with the starter only .... for a while. I just hope that you haven''t waited too long to oil-soak the engine. .... your ''mechanic'' should have recommended this for you to do right away on the **least suspicion** of water intrusion into the combustion chambers.
