intake heat shield removal

I'm getting ready to start putting together my rebuilt engine. Need to clean the intake manifold. Thinking some metal particles from blown engine might have gotten under the heat shield. Is there a way to remove the pins that hold it on and then reinstall them. Seems I've seen something on this but my search turned up nothing.
Also you radiator guys. Can all the particles be cleaned from the oil cooler or should I just buy a new radiator.
Thanks Gary

 

Take wood chisel and pry them up, then put them back in when ready to ***emble.

 

They have a spiral shank.
I use a brand new pair of small vice grips..Lock down hard on the head, and twist counter-clockwise..
After you clean everything up, tap them back into place with a hammer..

Yes,you are correct that you should take the shield off.
I use a small chisel or screwdriver and with a hammer give light taps between the shield and manifold where the rivet is.Move the chisel/screwdriver around the metal surrounding the head.Usually they will work out enough to grab the pins with vice grips or water pump pliers.Just don't go animal with it.
There will be **** under there.
Use the same rivets to install,I put a dab of red Loc***e on them.Light blows with small ball pien.If they are giving you trouble,put in freezer for a couple hours.Think new ones are available but I have not used them.

 

Thanks guys!

 

Got them. Glad I did. The pins are a little different than expected. Yes that is a piece of bearing next to the pins.

Thanks again.

 

SR,
I usually tap the holes and replace the pins with screws. You do what you are comfortable with but that is what I usually do.

use ****** cooler flush designed for this purpose.

 

Thinkin that might be the way to go. Don't want anything to fall down in the engine again.

 

Steel Rebel, If you are talking about the trans cooler tank underneath the radiator just install a new proper, independent trans cooler along with new trans cooler lines and forget about the radiator. But please, can you give me the lowdown on what happened (maybe the thread that describes the carnage) and where you are in the rebuild. I think I remember you from another web site. Get me up to speed and I will help as much as I can.

I've about decided to do that. Just not use the radiator engine oil cooler and go with an aftermarket one.

Not sure what really caused the rebuilt 454 in my truck to spin a bearing. Maybe a bolt left in the valley. Maybe not cleaning out the oil cooler. Maybe built too tight. Maybe, Maybe, Maybe.

Just trying to not have it happen again. Having first original engine rebuilt by a reputable rebuilder. Trying to think through everything before doing it. Might have to rely on you guys for more info. So hang in there and thanks again for all the insight.

Sorry for the confusion. I'm not completely familiar with Chevy truck cooling systems. If the spun bearing trash got into the cooler, time for a new one w/cooler lines. They can never be completely cleaned. In fact, if the old engine is simply worn, no internal damage, I would have it rebuilt as you have suggested. I personally don't trust cleaning a short block when trash has circulated thru the oil p***ages. Invariably there will be something left behind. If you have the old short block rebuilt and use the destroyed engine's heads, clean them thoroughly, perhaps even dis***embling them for cleaning. Also 86 the cam, lifters, and push rods. If you use them, make sure they are clean, clean, clean.

I might be paranoid, but I have never lost an engine.
