My Honda Accord was flooded in 3 feet of water. Once car dried, spark plugs and coil packs were removed to check for water, they were dry. The oil was changed due to water being in the oil after flood. Now the car makes a constant fast tapping sound when running. What could be causing this and can you please tell me what to do further.
Dealing with a vehicle that is flooded can cause many problems. Being that you have replaced the oil, you may be hearing a lifter tick. this sounds like you may need to have a top end rebuild. I recommend that you have a trusted mechanic take a look further to ensure that you don't have any deeper problems.
