Didn’t go out last night was in the mid 20s All pulled apart. Anyone have a suggestion what to clean the lower intake with, I've seen people say they bring it to a shop to have it cleaned.
Is it blasted,parts washed, boiled in a solution, brake cleaner, or mineral spirits what would you do? Thanks

Use carb cleaner and a stiff brush to get in the corners and tight places.

That’s not bad IMHO, just make sure mating surfaces are nice and clean. I had some putting in the front corner/#1&2 area but sealed fine. Carb cleaner, wheel brush on a drill, some sandpaper and elbow grease. That’s by far the crappiest part of the job.

These work pretty good as well.

What about this can’t see other side do you think this is a crack or just in the casting and what are these holes for not all in the same spot like random one is right on the edge of the injector hole

 

[liquify33]

No idea on either question. I’d roll with it though. New lower manifold on the Bay is $200 ballpark if you’re concerned.

ETA this:

Shows the same holes.

That does look like cracks. Is there water on the other side? didn't look like it but you are there. If it is only intake valley you should be ok. Intake Manifolds around here are 35-40 junkyard.I haven't seen one crack before. Try a drop of acetone on crack to verify its not a scratch. It will pull right into crack.

Make sure you keep it very clean during reassembly and IMO, you cannot go wrong with Fel-Pro gasket kits. Better than OE in many instances.

Curious, for sure.

One valve cover has direct vacuumn, the other air cleaner vacuumn. Clean for a hi mile. What oil you using? Valvolene Dino always makes a dark film as you call it, but the rest stays clean.

Spoke to a friend he says pvc side thinks its moisture but I beg to differ

Ok upper and lower intake back in sanded,primed,and painted valve covers in spray booth now off to oven to bake on finish (top of furnace) spider was a little tough putting it in hope this is my problem one injector in way of throttle body but installed as per directions can’t really move it

 

[Kelsda]

Ok finished up spider conversion code 301 is gone drove and idled nice 45 minutes later boom check engine lit up wtf po154 it’s an 02 bank 2 sensor 1 clear it, back on po152 same bank 2 sensor 1back and fourth every time I cleared it so tonight I cleaned with carb cleaner swap out 02s from left to right good news now I have po134 bank 1 sensor 1 so it is safe to say sensor is bad and found this on the side of the road. Brought it back to the store earning a free pie for my honesty
