Hello,


My message originally started here : http://pantera.infopop.cc/eve/...90052674/m/233101936
but since it's not anymore the right section I continue here wich is a more appropriate section.

Let's make a point : I'am from France and I have now a 1971 Pantera in my garage wich I bought myself in Indianapolis.

I have some problems with it.

The cat has been seating for a long time after a restoration. Last days I had several rides with it and it appears that I have a leak....not a small one.
It goes all over the engine, it reaches the back window as you can see on the picture.

Yesterday someone who knows a little bit about american engines came to my place, he thinks upper engine gaskets are shoots...

Hard to say, I'am going to restart the car and to look at the engine bay to confirm...I didn't do it yet.


See on my picture, waht I call "upper engine gaskets" is highlight in red.
I speak well english but I'm not familiar with mechanical terms but I think it's the right term.

Also see on my picture oil all over the engine is highlight in blue.

I want good stuff for my car...well in fact I just want to stop that leak...
So where can I find on Internet the gaskets I need ? and is it hard to replace myself ?

The leak might comes from somewhere else ??? Any idea ?


Another question, is the accelerator cable normal to you ? it seems that it has been badly fix...


Thanks to all of you for help newbies like me !

The left most arrow indicates a leak from the valve cover gasket. It may be the bolts are just loose. However, replacement, if necessary is very straight forward. Recommend a gasket with a metal core which will maintain its shape. The other arrows and the blue circle are leaks from the intake manifold. Not unusual on a 351C. A gasket kit includes "S" shaped gaskets which sometimes seal, sometimes not. Some people prefer a bead of RTV instead of the gasket. Once again, not difficult to replace. Once advantage of the 351C design is the intake does not contain coolant so taking one off is fairly simple.
Frederic, Careful there is always some sweating (transpiration) versus a leak - where you can see a drop. Very few motors are totally dry.

Not saying that there might not be other problems.

If it is spraying oil all over the window it should be easy to find. That would be a major leak that is misting or spraying oil! Check the remote oil filters they are problematic and the dip stick connection on the front of the engine.

That vacuum line for the power brakes is looking scary along with the throttle cable. I wouldn’t drive it until that is fixed. The valve cover cap on the driver side should be vented to the air cleaner. Here are a few links that should help:

it's really leaking a lot, I have lot of oil on my back window.

Something elso to check that may be a leak NOT requiring gasket replacement.

Your Pantera has remote oil filters mounted on the wheelhouse brace. This is not original.

The hoses to and from those two filters must have threaded fittings. I would check all of them and make sure they are tight. Also, the hoses probably attach to an adapter plate that mounts where the stock oil filter was mounted. This adapter can unscrew over time, and it will leak a lot of oil.

This is what the adapter might look like. It will be at the front of the engine, behind the driver. Follow the hoses.... Wink

I suggest for you to take off the interior access covers, and look at the front main seal. An oil leak there will get on the damper, and oil will get all over the front of the engine and your window glass. I can only see oil all over your window by being sprayed there (under pressure) or flung there (from the damper). Let us know what you find. Rodney

That is a good idea and you would want to inspect the front of the engine on a new car for belts, etc. But you can easily see that area without jacking up the car by using a mirror and a trouble light. You do this from the side of the car and just reach under the pulley area with the mirror.

Frederic,
I took a close look at your #2 photo, with the circles and arrows, I see two things:

#1 - very important - the sight plug of your carb secondary float bowl has come out. It is lying on the intake manifold / head, below the bracket of the dip stick. Maybe you took it out, or maybe it fell out. You must put it in place before running the engine again - that is a serious risk of fire.

#2 - to the right of the oil pressure sender, I see a gap between the intake valley pan (turkey pan) and the end seal. A red arrow points to it. I think this is the leak of oil around the sender.

When an engine is rebuilt, it is common to mill the head and / or block surface; for flatness or to raise compression. When this is done, the intake surface of the head (or manifold) must be milled also, or the manifold will not fit. It is usually the head that is milled, so an "out of the box" manifold will fit.

It is possible this was not done on your engine. If true, there may a gap at the front. Look there for a possible oil leak.

Good luck, Rodney
Sure. I am looking at your photo with the red arrows and blue circles.

Between the oil pressure sender and the ignition coil, you have a red arrow pointing at the back of the intake manifold. At the point of that arrow, it looks like there is a gap between the intake valley pan and the rubber end seal. If so, oil would leak out there, and pool around the sender. If indeed oil is leaking out here, it is possible there is a similar leak at the front of the manifold.

As for the little plug from your carb - look at the right valve cover. See the bolt that holds the dip stick bracket - look about 5 cm. down and to the left. Just near the #3 intake port, there is a little brass plug.
