Engine cleaning advice
Having been under my car a bunch over the last month, doing coils and exhaust, I noticed it could use an underside cleaning. Nothing leaking, but years of grime, and dirty aluminum. Any advice on how to do this or what to use? I don’t want to spray it down with chemicals, and hose it off to find myself a huge repair bill

I noticed the same dirty underside when bore scoping my 997.2 coupe. I put alcohol on a rag and wiped the surfaces down and I also used Armorall on a rag. The aluminum of the engine is mostly surface oxidation and cannot be easily rubbed off, but a stiff brush will dislodge the dirt. I have a pressure washer but didn't use it as it would surely put water in places it didn't need to be.

That looks great!
There is a protection coat from factory what is removed when cleaned. What is the plan to protect the metal when cleaned? |
