INTAKE MILLING

INTAKE MILLING - 08/01/09 02:04 AM

Having a problem with my 440. A few years ago I bought an intake off moparts. Finally got the engine running and I am having blue smoke out the tailpipes. I think the intake was milled, I cant get the bolts in without pulling the intake to one side or the other. I'm running valley pan and two gaskets on the intake side. How can I tell if its been milled, is there any way to correct it, or do I need to buy another intake?

IMHO,......time for a new intake manifold, you shouldn't have side to side movement like that, generally all that's needed is just the valley gasket to seal an intake, stock or aftermarket, yes some applications may require additional intake gaskets, you are sure you did a proper install?,.....valley pan first, then side gaskets?, then manifold,.....some guys make the mistake of put the gaskets on the ports first then the valley cover...and drop a gasket into the valley?

yes installed right at first i tried it with the valley pan,then gasket per side ,now two,per side. was thinking maybe i can open up the bolt holes?.

oblong the bolt holes

the manifold is not sitting rigth

the four ends of the manifold you migth need to grind them they migth be hang up on you on the end rails

milling heads and the block affect the manifold so dont think its the manifold thats the problem

Possibility, but not knowing the history of the manifold, IT may have been milled also,....seen plenty of good manifolds ruined because they were milled, or milled incorrectly?,....just a possibility,.....esp haveing to double stack gaskets on both sides,...IMHO, not good!

is there a dimension for a rb intake thats not cut?if it matters its a torker 2 intake. before i had the engine rebuilt i had a stock intake on it ,no problems,rebuilt engine and installed this intake now ,nothing but blue smoke,and intake ports wet with oil.

Re: INTAKE MILLING - 08/01/09 03:18 AM

did they reface the deck or mill the heads

oblong the bolt holes

put antiseize on the top of the intake gaskets

put the manifold on and drive it put some heat cycles into it

pull the manifold off the antiseize will show you a pattern where its sitting

I bet you the intake bolts are wedgeing against the manifold and not sitting rigth

pay attention to the four corners of the rails they too will hang up the manifold

the heads had a light cut to make sure they were flat. ,pulled engine apart after owning it for 15 years,found 040 over pistons,thats all i know.

heres a manifold I oblonged the bolt holes

ill give the oblonging a shot ,thanks for the tip with thr anti seize.

Don't hog the holes out. Take it all apart including the valley pan. Bolt the intake without a gasket or tin to the pass. side head. Torque the 4 bolts to spec. Then take a feeler gauge and run it between the driver's side intake/head and get the measurements. You should have less than .005" clearance all around the perimeter and underneath the valley side of intake, and the numbers should be consistent if you're going to have success sealing it correctly. If you can't get the feelers in at all then it'll have to be milled.

Also note if the bolt holes line up on the driver's side.

o.k ill give that a try first.if its off how will i know how much to mill? i wont be able to do anything till early next week,so ill let you guys know whats up then ,this is great keep the tips comming guys .

Take it from someone that's been down this road. Do the basics first, you may not have to mill anything. There's another way to seal an intake that involves cutting off the runners on the tin.

If milled Heads....I'd lay the intake on the heads with no gasket and align the bolt holes as well as possible. I will take an awl and scribe the intakes bolt holes radius above the cylinder head intake bolt hole. Measure the dimension of the cusp of the radius vs. the top of the heads bolt hole. I divide by two, add in half the gasket width and have the manifold milled that much on each side. This will get the intake to bolt on. Unfortuately, the core shift of aluminum may require the intake to be ported to get an acceptable "port match" So far its worked for me!

Re: INTAKE MILLING - 08/01/09 04:34 AM

The way I read this we have two posters that think the heads have been cut so the intake is sittint to high on the bolt holes...But the original poster is saying the intake sits to low & he's tried stacking gaskets to remedy the problem...

Do you still have the original intake?? How do the bolt holes align with it??

any chance this is not a 440 intake ?????

o.k pulled intake off as suggested pulled all gaskets ,valley pan off. set intake on ,bolted passenger side down . all bolt holes line up,i was able to get all the bolts in the intake . removed the driverside bolts ,only had them in finger tight,did not see any gaps. used .004 feeler guage around where intake mates to head on the driver side. i was able to get a .004 and a .005 feeler guage between the intake and head. also the intake is a edelbrock torker 2 440,thats what it says on the back runner. so now what do i do guys???

Mock it up again w just the valley tin & no other paper gaskets & see what you get for fit.

When milling heads it is nver (except under extreme circumstances) to mill the intake manifold. It is recommended to mill the intake side of the head. Milling the intake makes teh intake specfic to that engine set up. Milling the intake side of the heads makes either or usable with other combos without further milling.
In your situation slightly oblonginh the intake mounting holes will suffice. You will NEVER notice any difference in performance with such a slight difference.

Very likely would need a dyno to tell the differnce as it very likely would not even effect the et enough to be noticable.

That was my first thought. Do you really have a "B" manifold?

Re: INTAKE MILLING - 08/04/09 05:46 AM

up date on this problem.i pulled everything apart ,cleaned valley pan gasket,lots of silicone around the ports,cleaned up intake,some silicone stuck to it,bolted on ,started up with no smoke out the tail pipes.i probly should have mentioned it at the start that the engine was assembled by a guy who builds buicks. any way went back to basics and solved the problem.
