Another VERRY important point I forgot to make explicitly.
The bearbox surface that the gasket goes against MUST be 100% dry and oil free. Use brake cleaner aerosols spray or carburettor cleaner aerosol spray to clean it and dry it very carefully. It is a good idea to let the open gearbox drain for a couple of days before cleaning it, and have the sump assembly all ready to fit once it is cleaned and dried.
Gasgacinch on BOTH the gasket AND the gearbox.

Hello Greg.

I know that it is necessary to clean perfectly the Pan and the gear box surface before Gasgancinch.
I will respect your procedure perfectly.
I have everything I need in my garage to do the perfect work, and I’m sick and tired of dismantling that Pan four times already............

I’m still going to wait for the temperature to increase a bit to get the job done.
And sure I will pass with big palisir in the spring to Digoin with the E type.

Regards.

Philikat.

Looks great! Very sensible to let it set good and hard.

Hello Greg.
I took some time to answer you because the last assembly didn’t work, I still had oil leaks after 15 days despite all the care taken to the work.
I checked the pan with a comparator and it’s completely deformed by the tightening of the screws.
As I had 2 pans I decided to use one and strengthen the edges with 4 mm flat iron that I formed all around the case.
Once in place I welded the flat iron in the rim of the pan blocked onto a mechanic’s marble.
Photo 1 an 2




This work finished I had rectified the surface by a milling machine.
Yet i have only a little section with only 0.2 mm under the surface and everything is totally rigid.
I do the assembly this weekend without gasket by putting only LOCTITE SI 5980 Quick Gasket between the pan and the gearbox.
24 hours of drying and filling.
I cross my fingers, it will be 4 times that I empty the gear box and disassemble the pan ...........



It is nothing to compare with the original pan.
Regards

Have you checked your breather pipe and crank vent valve are all clear

Hi.
Thanks for your advice.
Yes I did all possible control around the gear box, and of course the breather to be sure to get no pressure into the gear box.
I made also a drawing with all dimensions to understand how the oil level works when the gear box is cold, hot and turned off.
I'm a perfectionist and I real can't support any oil drops under my cars.
I need to admit than was only in two weeks few little drops on the floor .........but to much for me.
When I was looking back some photos, I took during this major overhaul, I remember than was no gasket on this pan!
Yet I go to install my montage.

Regards.

I think that is an excellent design and idea, with a very good chance of meeting your high standards. Keep us informed about progress.

Out of interest, and knowing that you tried my idea using The Right Stuff and glass etc, how much oil actually dripped out every day?

Hello Greg.
Your idea to use a glass is really good.I found that my leaks were reduced after using your method, but not completely!

Like I said.... 2 drops per day....I know it is almost nothing but.....I can't see that under my car......and also because it is uncertain how that will progress with the time.
Just 2 hours ago I dismantled the pan from the gear box, all washers under the screw heads, were tapered as they are tucked in the holes of the pan!
Now with my 4 mm flat iron, that will be impossible.
It was quite difficult to put the pan away, this Gasgacinch is a real fantastic Gasket (Glue), It stucks so hard.
After Lunch back to garage and implementation of the modified pan.
I cross my fingers.
Verdict tomorrow afternoon.

Regards

I used the right stuff with no other gasket and it hasn't oil leaked from the pan since. Works great.

Pan bolts are only 10 ft/lbs

Good evening everybody.





No leaks finally, I'm so happy I can't believe......... I will wait tomorrow to check again under the car,.
The mechanical assembly I made, leaves little chance to chance and it should be definitely waterproof.
To be honest, I wanted to do this mechanical assembly as soon I discovered these leaks, but the amount of work I had imagined to realize these reinforcements discouraged me and I opted for other solutions to make this adaptation anyway!
Now I will use my car and enjoy every moments behind the wheel.
Thanks for your advice and your support.
Philippe.
