Engine cleaning

[rockford33]

I was under the car last night and noticed quite a bit of oil build-up on everything. The car is 12 years old and somewhat rare and finicky, so I want to be extra careful in trying to clean anything. There is quite a bit of sludge on the cross-members, the underneath of the alternator (don't know how it got there, but how can I safely clean it off?), etc.. Since parts are increasingly hard to come by (or not made anymore), and I am not sure were every single sensor is located, what would be the best way going about cleaning off the sludge? Not looking for super detailed, just a little cleaner so I can tell where any iol leaks might be coming from.

Thanks,
Neil

GUNK, WD-40, Kerosene are all common solvents used to clean engines.

I have used all of them to clean engine bays and they work well. I usually follow-up with a near full strength soak with SImple Green to remove any remaining grunge or oily film remaining.

I use a degreaser from Costco that is made for house use. You can mix it with water but I use full stenght. Its about 4 buck a gallon and works wonders. I agree thought that slovent and that likes of those are really that way
