Default Blown intake gasket

Well guys I figured out whatís wrong with my 4x4 truck. Itís got a blown intake gasket. I donít know how it happened but itís whatever. I need to know how to do this, because Iíve been told the intake manifold is attached to the motor mount and it makes it a bit of a pain to change. Does anyone know weíre I can find a guide to this. Iíve hunted everywhere and canít find anything.

There are just a couple of 12mm bolts underneath the intake manifold you'll need to undo. The bracket that holds the intake manifold up bolts to the block right by the passenger side motor mount but there's no need to undo the lower part. Drain the coolant before you start since it runs through the manifold. It would also be a great time to replace the bypass and heater hoses, especially the one that runs down to the block.

There is a lower bracket attached to it that is held by 2 12mm bolts. It's a tight fit to get at the lower bolts. A lot of the work will be through the fender well. Start by hosing the egr valve mounting bolts with pb blaster. Spray everything you can get at as well, let it soak in.

+1 on the EGR pipe. Forgot about that one. The big nut takes a 30mm wrench.

You can cheat on the egr pipe by just loosening the egr valve from the manifold.

or.....if you know where the leak is, you can ghetto smear a bunch of RTV on the outside of the IM and hope for the best. I did that once and it worked.

Clean the surfaces, replace the gasket, and reassemble - torquing to specs.

Iím talking about the mount bolts on the bottom of the intake. Iíve never done an intake gasket on one of these trucks. If anyone has any pointers for this Iíd appreciate it.

On the older Z24i versions, you need to take out all of the bolts except for the two underneath, near the middle. Those two were studs. Just loosen the nuts, break the manifold loose, and lift it straight up off of those two studs. No need to take the nuts all the way off. The manifold is slotted in those locations for that reason.

Maybe the KA engine is the same way.
