The LIMs aren't even on the car in that pic. That'* all the filth and gunk that was under them.



That right there is the remains of my LIMs

What about this stuff, guys? It isn't B12 Chemtool, but it looks like it would be a good cleaner for soaking my intake manifold and throttle body in. I could just soak them in a metal pan.

Remove all of the sensors from the throttle Body before you do that

All 3 are already out, as well as the sensor in the manifold.

But, otherwise, that stuff should be safe?

Never used it on a TB... But it cleans carbs... I'll let others more versed with that stuff answer this one..

After cleaning the manifold, I plan to powerwash it and let it dry for a while.
Nobody around here sells that Castrol stuff :( I'd have to go to Milwaukee for it.

How about this?

Should be about the same as the Castrol, and far less caustic than the Berryman for soaking my intake manifold and throttle body overnight.

Crapola.

It looks like Castrol Super Clean, Simple Green, and the Kafko oil eater all damage aluminum Are there any safe dips out there for soaking aluminum parts? I tried Gumout carb cleaner and a brush on that throttle body and it barely had any effect.

Use the Chem-Dip. Soak for an hour or so. I've been using it for years. Rinse with water and air dry.

Use a razor blade on the heads, and make sure to stick a paper towel down into the port so all that crap doesn't fall into the engine when you start it up.

Any reason for a razor blade over a gasket scraper? (besides cost)
