Took a pic of the damage in question. Take a look. The cam covers were blasted too and ready to go, they are just sitting on the motor with the old gasket for protection from dust/debris until good painting weather gets here.

I'd find a new one to put on, if it were an external piece I'd JB Weld it but not up there.

finally!

Second Sean.. if it was not a spot that was under stress, which it is since it has a bot attachment, and/or critical to sealing; then JB Weld..

IOW, it it was on TOP corner away from sealant face or bolts would use JB Weld..

That can be easily welded.

I have like Greg found a couple manifolds with holes.
These are caused by the intake coating flaking, and the metal corroding.

As for cleaning the intake, I use a 3500psi gas pressure washer with a rotary blast nozzle.
I blast 90% of it out in about 5 min then rework all the corners and nooks and crannies. I then go in and scrape everything to ensure that nothing is left inside the manifold.

Sucks, but a simple weld and repair. Get them to put material on the inside, with a small bead on the outside. Grind the outside down, when done. File the sealing surface flat. Never know it fell off.

That if far more than a "crack" and it has a threaded hole for the side cover bolt, as usual listen to Mr Brown

I meant a piece cracked off. Alright Greg maybe i will get it welded, there is a great place my Dad has dealed with for welding for years. Btw thanks for letting me know you have those 10mm to -AN compression/adapter fittings for hard tube. I'll need 3 of them, are they 10mm to -8AN or -6AN because i would need 6-AN, they are all going to be used for the high/return pressure side of the system, closest to this would be -6AN, from resevoir to pump inlet, closest would be -8AN. The rest of the fittings i can source from a local Aeroquip distributor at a hose place here in town.

When are you guys going to start using baking soda as a blast media? It literally explodes when it hits a solid surface and desolves in water.

I've been using soda, on my Harley engines and other aluminum parts for 30 years. I put the cleaned parts in the ole lady's dishwasher, hit the pot scrubber cycle and run them thru. BTW no soap. The parts come out looking new and they're clean, inside and out.

For the ouside of the engine cases, and heads, I have a seperate cabinet with glass beads. Back in the dishwasher, and they have a show quality finish that lasts till the next rebuild. I do paint the insides of the engine cases with Rustoleum primer as a sealer.

Soda works ok... and it's pretty much inert so you can get by just wearing a dust mask and goggles as PPE. However, i still think good old sand does the best job and i use a P100 NIOSH respirator when i'm using sand. Coal slag works great though, especially for rust, and much less silica in it than sand.

I tried soda. The intake and valve covers ate up two bags and then went to dinner cause they were hungry for more. Ended up using oven cleaner and basically melted the paint off. Then we soaked them and powder coated them. Still holding up after three years. Next time I am sending them off to Greg Brown to be done.
