Got oversills fitted, but I can't fit the genuine bits for a while

So, was going to do the next best thing (from what i've read) and drill some drain holes in them.
Where should I, and how many?

And, Will it still be ok to get through its MOT? They won't take it as rust or any corrosion will they?

Obviously I'll be primering it all and doing it correct.

thanks

I hear this advised a lot and I don't think its a good idea at all.

When oversills are fitted they tend to rot out the floor(at the bottom where seam welded to the car). This is because the water collects here and can't get out.

By drilling holes in them you'll allow water to be sprayed into the new holes and make the situation worse. If you look at the sill and where people drill the hole(in the same fashion as the originals) you should see what I mean.

Proper sills don't have this joint at the bottom and the water passes through the vents and goes straight out. They do rot out where they are welded to the car body, again because water gets trapped in the welded join and can't go anywhere. The same applies to the jacking point in the sill as well, this is again a water trap and I never refit them. I've seen cars with near mint inner sills ruined by the jacking point rotting out..

I would spray some rust convertor into the sills and then fill with waxoyl, if the water can't get into the joints then it can't rot them out. Its also worth considering fitting a bung into the jacking point as well, this will stop more water getting in.

Cheers for that shifty, I hadn't really thought about filling it with waxoyl but it seems a logical thing to do.
I'll put the drill away then!

I'd spray some rust convertor first.

This is a good picture, note the damp and severely rusty bits at the bottom(where it was welded to the car floor)

The water has collected here and started to cause damage to the floor.

Makes me wince everytime I see where people have peeled oversills off
Just wish I was wise of them before I went car hunting

[Shifty]

I've got much worse pictures than that one..













Enjoy!!

The red one was a mess, heres a cross section of the floor..

[Lee_bash]

Might save myself the pain of finding this and just replace the entire floor, from door step down

i peeled my oversills down by hand.... the welds were not connected at the top and the originals were totall gone and the inner sills ******* too..... i can only find a pic of the heelboard end.......

To depress you further, the door steps don't usually fare too well when oversills are fitted!

[mini_in_progress]

found one a bit better.....
