Guys, just want to know what to cover or protect when having an engine washed

 

intake system?

 

Watch out for the johnson rod and your blinker fluid's, they can be ruined by water...

 

You just want to keep the water away from the MAF. Just don't blast any conectors with high pressure water. You can use plastic bagz (sorry I couldn't resist) to cover some of the conectors just for extra safety.

 

Don't cover anything. Just don't use high pressure water. Use low presure water and soap. Let the soap do the work not water PSI.

The only high PSI in your engine bay should be your turbo not a water hose!

 

I would suggest steam cleaning instead.
