Looks like a Katrina victim. There's no way to fix that rust, you could just spray on some mild degreaser, let it sit and spray it off. It probably won't do much but that thing looks rugged!

You're going to have a hard time getting all the rust off that engine while it is still in the car.

Then yes I would hit any rust in the engine bay. Simply hitting the rust with a wire brush won't do you will need to coat the exposed metal. But Im sure you already knew that.

No, the rest of the car is in good shape and under the car has no rust. The previous owner probably didn't clean the engine bay much. I'm pulling the engine out to go through it, fix the clutch and cleaning everything as well as I can well I'm at it.

Yeah that is about the only way you will get that engine and bay looking good again. This reminds me I need to give mine a good cleaning in the spring-gotta love a rear hood scoop

Scrubbing bubbles, search for the thread to see the effectiveness.

Nothing to do with your question but have you driven the car yet? How does it run and how many miles on it? Im just amazed because i've never seen anything quite that bad.

If I may make a suggestion: Lose the blow off valve and intake immediately and swap back to stock parts. Unless its been protuned that is bad news. As far as cleaning that you are looking at a lot of time and elbow grease.

search on youtube for electrolysis rust removal for your fasteners, your intake manifold and intercooler you could take the time to polish them up with a wheel.

it has no front grill, so water would easily get into the engine bay, its my guess.
(looking for a stock 02-03 front grill anyone)

blow off valves are a very highly debated topic. I am currently looking for a stock recirculating valve, because BOVs tend to annoy me after awhile. But im getting an SPT or cobb intake instead of the one on now. Tuned by an cobb accessport to stage 2. Car will be seeing a dyno in the late summer to early fall. Most of the work, if not all, will be done before car is registered in the summer.

Looks a lot like mine did...I used Evapo-rust on several of my fasteners then coated them with a layer of POR-15..looks better, but when timing belt comes due, gonna replace all the fasteners I take out during the job.no reason to skip out on a few dollars to get the cruddy ones out
