I have a gsr motor (boosted) and went through some flood water, the car died and wouldn't start for a while, then it started, it ran but really bogged down and wouldn't do much past 4000 rpm. I got it home, it drove about 4 miles, and checked my dipstick and it has some water in it, also it looks like milk under the oil cap. what do I do now???????????????????????

 

rebuild your engine

 

is changing the oil a couple of times and driving it a bad idea. probably a dumb idea

 

don't know, never sucked up water into my engine

 

Depending on how much water you sucked up you may have hydrolocked it. Water doesnt compress like air does so when this happens things start to break, more than likely a rod/rods.

A tear down is in order imo to see what the damage is.

 

First id say change the oil, check the airfilter on the turbo if you have one, just make sure to get the water out of wherever it may be, ive seen many cars suck up water and not have the motors blow

 

1. remove the spark plugs
2. crank the engine ...if you have a lot of water in the combustion chamber it should shoot out through the spark plug holes. dry sparkplugs too
3. drain the oil completely
4. leave the spark plugs out over night and let the combustion chamber dry out overnight
5. replace everything,
6. add fresh oil
7. try and start
