Default Intake vavle cleaning - 07-08-2015, 07:57 AM

Quick question after I spray the carb cleaner and scrub with the wire brushes. How do I suck out the liquid? I don't want to use the shop van in fear of a boom. I currently use a oral ssyringe with a tube attached to it but it still leaves a little pool.

Why not use compressed air to blow out the tiny bit of remaining liquid?

What boom? I don't get it? How's a shop vac going to hurt anything?

They say the fumes from the flammable liquid can spark with the shop vac. Alright I'm currently using my blow gun and paper towell.

Dont use carb cleaner, its bad for the stem seals. I guess others have done this on the N54 but in general its a bad practice to fill the chamber with carb cleaner. Use a towel and air compressor to blow out if you did. You can use a detergent based cleaner but I would stay away from ether base solvents. You need to just walnut blast the head. You can make all the tools you need for 50 bucks at harbor freight.

I am in the process of doing this, but don't really have any idea what to get. What do you mean by "50 bucks at harbor freight"?

Looking forward hearing What I should buy from harbor freight. I thought I needed the shop vac adapter so that shells don't go everywhere.

I did the intake cleaning last month with carb cleaner. I used 2 cans of carb cleaner, a roll of blue shop towels ($2), a few brass gun cleaning brushes, some brass "toothbrushes".

Please make sure your valves are full closed. I bumped the engine with a switch connected to the starter solenoid to ensure that each valve I was working on was fully closed.

I sprayed carb cleaner in the valve area and then scrubbed with my wire brushes. I had a wand with some thin 1/4 inch tubing hooked up to my compressor to blow out most of the debris. I would then use shop towels to wipe the area. I used a vacuum just to suck out chunks of carbon.

I got good at it so it was only taking me 30 mins / port. I'm sure you'll find a method that works great for you.

Goodluck!!
