If you tape off the Intake like i always do i just blast the stuff you see to bring the NEW LOOK back how would this cause an internal problem ?...i have blasted near 100 OLD ALUMINUM manifolds for folks an myself over the yrs with NO complaints.
I understand your point on not blastin the stuff that goes on or in the oily stuff ...but 15 or 20 minutes of tapin off will bring a NASTY lookin old intake back to new in a short manner ..an saves lottsa $$$
im Confused ???
Yes, lots of people blast intakes on the outside, and most of them probably don't tape off the inside, even if you do the tape never keeps all the beads out.
Personally I avoid blasting engine parts for the reasons mentioned earlier, even an intake.
I will agree with you that is can be done with a relatively small risk if you are careful.
I understand what you are saying about taping off the intake, that and a good washing after should not leave many glass beads inside to be drawn into the cylinders, but there is a chance, and it's easier to just avoid it.
I think it's best not to give people the idea that blasting engine parts is a good idea, someone may start with the intake and keep going...
A good aluminum cleaner and a brush, or walnut blasting is a safer solution.
