Steam Clean the Engine ? Yes / No ??
Is it safe to Steam Clean the Engine ?
i should think so. i run the car at about 3000rpm use some degreaser and a jetwash. some times she splutters a bit as it dries out. just watch out what you are spraying, avoid the electrics.
cover all the electrics with pastic (pastic bags are the cheapist) and you should be fine, steamer is better than a power wash, power washing can be to powerfull some times and blow off pulg leads and what not.
