How to bottom of intake manifold?

[DavidNC]

I gettin a junkyard explorer lower intake manifold ready for install, but the bottom has an 1/8th inch of oil crude. Half of the area is also covered by a metal plate. How do I get rid of this?

Engine degreaser, brake cleaner, high pressure washer or a hose.

If I don't hear of any better solutions, it will be the high pressure washer. Good idea.

After pressure washing, go at the surfaces that mate to the heads with scotch bright pads and afformentioned cleaners. You want those mating surfaces to be absolutely spotless before installing the intake; same goes for the intake side of the heads before install.

I;ve just started pressure washing, but can't realy get under the metal plate. Can it be removed?

is there something bolting it on?

 

[DavidNC]

It not actually bolted doe, it looks like for large round rivit heads holding it down. The be press into the manifold, but I don't want to start prying without know for sure.

just clean it the best you can... I would soak the lower in some type of degreaser or use gasoline as a last resort... those metal plates are oil shields and should be retained... one of them is to shield the pcv valve

mabey try taking the manifold to some sort of shop (tranny, engine building...etc) that would have one of those steam chambers that you clean parts with. i know those fuggers will take anything off...might even be able to get under that plate as well

 

[DavidNC]

It's getting there. The bottom came aprt after I removed the four press in retainers. I'll put it back after cleaning.

Yeah, they are press in rivets. If you remove them DO NOT try to reuse them. YOu have to drill/tap the holes and put small bolts in - not much trouble really.

Isn't that the same cover that they leave off of the GT-40 lower manifolds (if I remember right, my GT-40 had no plates on it)? Is it even needed?

 

[tmoss]

YES - you want the one big one or the two smaller ones - but DON'T go without them.

 

[Daggar]

I guess I'll have to take a better look next time I pull it apart. Thanks T

 

[DavidNC]

Are bolt heads okay, or should screw heads be used?

Either - and use some loctite blue on the threads.
