Factory aluminum intake casting "cracks"?
After bead blasting my aluminum intake, I noticed several "cracks" or "fissures". I'm guessing they are just cosmetic, but thought I should ask what others think. I'll be painting it with this...

Nothing to worry about with those. They are just surface, irregularity's.

Re: Factory aluminum intake casting "cracks"?
You are going to paint your aluminum intake GOLD or bronze? To each his own I reckon. (I agree. Those do not look like cracks to me. What do those areas look like on the underside??

Re: Factory aluminum intake casting "cracks"?
Did you blast the underside also?

[QUOTE=Ziggster;1964653]Haha! No, painting the intake "natural" aluminum. The damn lighting in my shop gives it that bronze glow.[/QUOT]
A perfect example of why you can't post a picture of a car and expect someone to identify it's color.

Re: Factory aluminum intake casting "cracks"?
Yep. I just installed two 4,500 lumen LED shop lights in my garage. What a huge difference. I can now finally see!
Yes, I did blast the underside. I was going to paint it last night, but while giving it another go over, I discovered some areas still covered in grease/dirt where the generator mount is located. There was what appeared to be a wasp nest and dirt inside one of the runners, and I had a hell of a time trying to get that stuff out. Still not comfortable with the state of cleanliness. Will do another "touch up" job in the cabinet and will "hose out" all the passages. |

Re: Factory aluminum intake casting "cracks"?
Okay,Here is my take on bead blasting the underside. It happened to an engine I know of that was rebuilt. The abrasive that got imbeded in the porous aluminum began trickling down into the valley and into the cylinders,hence virtually ruined the bores.The engine had to come apart and redone.The intake was then hot tanked and steam cleaned to purge out the abrasives.

Re: Factory aluminum intake casting "cracks"?
That is a damn shame about the engine. I've got my engine next to my blast cabinet, which I know is really not good. I've covered the engine up with a large hefty garbage bag, and there is a very fine dust covering the bag from media escaping from the cabinet.

Re: Factory aluminum intake casting "cracks"?
OK, I have to ask, why would you ever consider blasting a block? IMO it will never be usage after that without a whole lot of work. What is the point? Very fine particles get left behind that are very difficult to remove no matter what you try. They are abrasive and will work there way out and into the oil etc and eat an engine up in short order. You are missing wasp nest and grease deposits how do you expect to locate extremely fine particles. This is a very, very bad idea.

Re: Factory aluminum intake casting "cracks"?
Haha. Not blasting my block. Engine is complete (short block). It is under wraps but is next to my blasting cabinet. Was blasting out the intake at the edge of my garage door while it was dark out last night. Was going to pressure wash it today, but also ran out of daylight. Will carry on tomorrow.
