If the intake is aluminum your antifreeze ate a hole in it.The same thing happened to me on my wifes van ,I was able to fix the hole with JBweld and 3 years later still no problems ... Good luck.
Essentially, poor design. Gm's 3.1 and 3.8 motors are notorius for them failing. Even the Lincoln 4.6 falls into the same category.
The leak would vary on the size of the hole or seal failure.
Remove the intake manifold and take it to a welding shop that works with aluminum. Let them determine if it can be saved or not.
There is a tapped hole next to the distributor hole in the intake manifold.
On a small block Chevy the distributor goes through a hole in the intake manifold. On a Pontiac the distributor goes behind the intake manifold.
the pcv valve is located at the gack of the intake manifold there should be a gromet at the back or a big hole if theres a big hole you also need the gromet and it connects to the carb and air cleaner. I hope this was helpful It's in-line in the hose on the back of the intake manifold.
A hole in piston is caused by extreme heat! most likely cause is coolant being introduced into the cylinder during combustion from a leaking head gasket,faulty intake manifold gasket or a defective cylinder head!
The intake manifold are very bad about corroding a hole in them which means that you will have to replace it.
I had a hole small hole in one of the manifold covers on my truck, noticed it after I saw lots of steam coming out of it, so I used heat tape( got from Checker Auto Parts) to cover it, and to date it's still holding. (mind you this is only a temporary fix)
It blew a hole in the intake manifold? You probably broke a pushrod. Get this engine to a mechanic or engine rebuilder.
Start with removing the intake manifold. If it still not found you will have to drop the oil pan. If it made it's way to the bottom of the oil pan it would be harmless, but you will not know.
check the rubber tube next to the the lower intake manifold gasket, there is probably a hole on the underside of the tube coming directly off the engine. (it is a manufacturer defect)
there is a vacuum hose for the pcv system on the back of the intake that sometimes gets a hole in it. this may cause your no idle condition
"Manifold gasket" ? whick one? Upper intake MG,Lower intake MG or exhaust MG? I thinks you mean intake MG. The Upper intake MG is easy on. Just undo the bolt and clear the gasket materal, then replace new upper intake MG. The lower intake MG is a little bit hard. Carefully clear the old gasket material on the manifold and head, clear the bolt nad bolt hole in the head, then carfully install the lower intake MGand double check the coolant passage in ordeer to void the coolant leading. The last step is to torque corectly the bolt. good luck.
There is a 1/8"NPT tapped hole at the rear rail behind the intake manifold. There is a 1/4"NPT tapped hole just above the oil filter.

There is no hose under the intake. If it is leaking coolant it is because the intake manifold is cracked on the seam just behind the alt. You have to replace the intake with the modified one from Ford. It's a 6 to 8 hour job. Quote:There is no hose under the intake.

There actually is a hose under ther intake but I am not sure where it leads. I had a pin hole in mine and have gotten to the hose but have not changed.
I had a 1997 Lincoln Towncar with this problem. It probably had the same engine. The cause was anti-freeze leaking from the intake manifold. The manifold was made of a composite material of some sort and was quite pricey to buy new. Before I got an estimate for labor to install I donated the vehicle to the Salvation Army.
Sounds like your looking at a p.c.v.(positive crankcase ventilation valve,if it goes from valve cover to intake manifold.
There will be a hole in the valley pan under the intake manifold. This takes a rubber grommet that the PCV goes into. Then the hose runs to either the large port on the carb, or there should also be a port in the intake runner that it can hook to.
There isn't one you take the 2 screws out to remove the map sensor in which plugs directly into a hole in the intake manifold that's where it gets its vacuum from.
In my 1995 Pontiac Bonneville the oil leaks out the intake manifold and drips onto the exhaust. An engine that has a gaping hole will hold no pressure.
Are you handy with a center punch, and a drill? If so, the best way to do this is to drill a hole in the center of the stud, and along with penetrating oil, an/or heat from a torch, use an easyout to extract the broken stud from the intake.
A small hole in the fuse line would cause a gas leak on a 1994 Honda Accord LX. In addition, a hole in the actual fuel tank would cause a leak.
on gmc's and chevy's there is a spot in the wiring harness that goes down the back of the engine block on the passenger side next to the distributor, this section of harness continuously rubs on the back of the block, more so if an intake manifold gasket was just replaced. it will rub a hole in the wiring loom and ground out there. check it out and see.
