Would like opinions on cleaning my freshly pulled L33

[jrblanke]

Hey guys, I wanted to get your opinion on my cleaning plan for my partially disassembled engine.

The engine is an all aluminum L33 that pulled this past weekend. It has a large amount of oxidization and loose grit. I pulled the intake manifold and headers last fall and stuffed some rags down in the runners to keep the big stuff out. The motor is currently on the stand, but still doesn't have an intake manifold or headers. I am planning to pull they heads to eliminate the DOD lifter system and to do a cam swap.


What do you think of my plan?


1. Tape intake and exhaust ports of cylinder heads so no material can get into the cylinders.
2. Blow off any loose material
3. While the engine is still dry use an air powered 3" pad to hit the easy to get to surfaces.
4. Spray engine with simple green and use the pressure washer to wash off
5. Use hand brush to try to get any more crud/oxidization off. Hose it off.
6. Spray with the aluminum etching cleaner, scrub with hand brush, power wash off.
7. repeat 4 through 6 if necessary.


I guess what I am looking for is affirmation that the above plan is a good idea or suggestions on what to do differently.

My biggest concern is getting crap into the cylinder bores since I am not going to be disassembling the short block. I think I will be OK if I keep that tape on the intake and exhaust ports of the heads.

Once cleaned I toyed with paining the engine, but I'll have to research whether the paint with stick to the aluminum.






Thanks,
