[jweir22]

How do i get this brown crap out of my heads its tough as nails,tried varsol,engine cleaner,power washer,maybe it needs heat like engine temperature.

You tried soaking in Mineral Spirits or just scrubbing them with carb cleaner?

[bszopi]

Just take them to a shop and get them acid cleaned and pressure tested.

it is probobly just from oil drying on there or carbon build up.
a high grit grinder should work like a dremel tool just watch what you hit.
high grit sand paper should work for the flat parts, like 2000 grit or some shit

Thats oil-soaked aluminum. The only way I know to get rid of it is to sand it down. However, its nto hurting performance, and its covered by your valve covers. Why worry about it?

[v6h.o.]

a good parts washer will get rid of that crud in an instant.

I have a parts washer with varsol in it and it helps takes that crap off

but you still have to scrub it quite a bit


Im doing my 3.1 turbo engine and that crap is everywhere

One of the best cleaners I've found is "Spray-9". It worked far better than engine degreaser on some old crud. However, it's a bit hard on the hands. Not sure if it's safe to use around rubber though.

OKay guys i found the cure i tried to use throttle body cleaner didn't work then i got some combustion chamber cleaner man that stuff is harsh but the stuff melted away like butter.Problem solved.Back to nice aluminum.
