EAsy solution m8 to the following;
1. Change Oil
2. Change Oil Filter
3. Change Spark Plugs
4. Air Filter (non oiled type)
5. Open the bonnet in the sun and let mother nature dry the whole engine bay
Doing all of the above should be your car back to it normal self, the water will only do damage if left in there (left to mix and dilute the oil)
Hope this helps m8
Cheers Ill do just that over the weekened
No dramas m8 and when you change your oil get some good stuff I use Nulon fast flowing stuff 10w 40. But I'm not sure what grade the MPS's should run.
And future reference dont drive through big puddles if you can avoid them
Good luck m8 let us know how she turns out. .
I've had a cai on for a very long time now with no issues, though I am careful. Just be concious of it and you will be fine.
