[DeTomaso] Unusual Techno Question: frame holes

[Larry Stock]

Drill some more 1/2" holes in the bottom of the frame rails to let out any moisture and any pea gravel that will also get in there, I originally did 1/4" holes but they got plugged up with road gravel so I re-drilled them to the 1/2" size.

Dear Larry,


Ah, I forgot to specify that the extra holes are on the top of the engine bay frame rails, which seems like it would aid water entry and not drainage. In the rear fender frame rails, the holes are oriented horizontally such that water spray from the tire could gain entry to the frame rail interior.


Warmest regards, Chuck Engles

Let it breath, especially if they can be also drain holes

Dear Forum,








I am working on my brother's Pantera and pulled the
drivetrain. I began cleaning up the engine room and noticed several
non-factory holes in various frame rails and in the frame rails inside
the rear fenders.








They were from one of the three previous owners and
certainly have no function now.








In my view, they permit water and moisture to enter the
frame rails. My first thought was to seal the smaller ones with some
black RTV silicone and cover the bigger ones with duct tape covered
with rubberized undercoating spray. Then I thought, perhaps all those
various and sundry holes might actually permit ventilation of those
dark recesses and *might* be left open.








Alex's car will ultimately, I think, be garaged in
Conncecticut.








Opinions? Leave open or seal up?








Warmest regards, Chuck Engles
