Finally did my walnut shell blasting. Took about 6 hours. I am sure I can do it again in about 3-4 hours.
Work wasnt that bad. Only problem I had was getting my manifold off. There wasnt enough clearance between it and the rear intake tube. So I removed the studs and it came right out.
I think the car idles a little smoother and is a little bit more responsive. Overall I am glad I did it and will probably do it again in about 15-20 thousand miles and see how it looks in there. I have in place now the BMS oil catch can and RB PCV valve. So it should have a lot less oil in the intake.
