i want to get my engine looking shiney like the first day i got it, 3-22-02 03 S-navi. Can anyone recommend a method of cleaning or even comment on how safe engine cleaning is. I would love to hear opinions before i clean the engine cause i dont wanna hurt my car....thanks

 

you could use the Meguiar's all surface cleaner
it's a lot of work though

 

Many people use simple green. I dilute it in water 1:1, then just spray it everywhere inside. Use a cloth to wipe off the really bad parts, then just rinse with a hose(not pressurised, just coming out with no attachment).

 

simple green or dawn works for me and i use a 1300 psi pressure washer to clean it off........first i suggest a 50/50 solution mix of either one you choose and soak the engine with it ...if you like you can use a brush ....if u have a cai or other type of air intake with exposed filter i suggest u cover that. Ohh and make sure that your engine is not hott when u do this i suggest you do it after the car has sat for a few hours. you can run your car after to dry the engine or just let it sit which ever u like....i hope this has been helpful...i do this same routine for the rims.

 

you just let water drip everywhere and it is ok?
