intake manifold problem!

[jmmorgan82]

i just installed a new intake manifold from Dorman. it is the newer one with the aluminum coolant crossover. well i got everything put back together and she started right up, but on the rear 2 bolts coolant is leaking out very quickly. the instructions said that there is no need for a gasket. anyone else have any experience with one of these?

You don't need a NEW gasket but you still need A gasket in there.(between the heads and the intake)

so is what they say- "this manifold is designed to eliminate the double sided throttle body gasket. do not reuse the original" bs or what? should i just throw the originals on there?

You don't need the tb gasket but you definately need the intake to head gasket.

awesome..looks like another 4 hours of work for me o well.. thank you for your help! its much appreciated. there anything else i should do while i have my intake off?

Change your spark plugs maybe,it's alot easier with it off.

good thought, just did that about 1k ago though

update: got the factory gaskets put on, and now its not leaking as bad, but it is still leaking by the rear bolts. any suggestions???????????

You bought a non-PI intake with the aluminum runner right? Are you following the torque specs? If you are and it's still leaking maybe try adding some RTV.

its part# DOR 615-178. i looked on their website and its the manifold they said was for 96-98. whats the difference looks wise between a pi intake and a non pi so i can look and make sure?

EGR tube

how do i go about removing the egr tube from the RH exhaust manifold?

I didn't... it's a pain in the ass. I removed my alternator instead to slip the manifold out. I don't have any pictures on this computer but I think the PI intake is much "deeper" than the non-PI.

I thought only the shape of the ports were different? Cause the ports on the PI and non-PI heads are different.

If you stand them side by side, one is noticably "taller" than the other one. The other tell tale clue is on the aluminum runner the non-PIs have two sensor holes where the PI only has one. But a second one is typically tapped when someone is putting a PI manifold onto a non-PI head.

And yes, the port shapes are different too. The non-PIs are more like a tear drop where the PIs are more like a slanted square with rounded corners.

i checked them out side by side and they are identical, so thats a relief. i put some rtv around the coolant ports and let it sit overnight. im letting it run right now to see if any coolant leaks. thanks for all of your help guys.
