Found my boot leak, an unsealed part of a welded seam on the right side.
Annoying that it dampens the carpet etc and I've got a feeling it's been there since new.
Yes once they've had a prang, all the seams are suspect.
No prangs to this one but it does have a tow bar so perhaps the strain is too much for the thin metal and seams, or maybe it's just been there since new.
I found it by blasting water up from below all around the fuel tank and floor. Pours in if you get the hose at the right angle.
my boot was leaking for ages.. only on the right side and i couldnt figure it out.
finally figured it out.. screwed up the little rubber knobs under the lid to sit lower - so the lid would closer tighter. Also the metal hook in which the boot lock closes on, that was banged down jus a little so once again the boot lid sits closer on the seals.
If you're towing anything of a decent size you used to be able to get genuine 'tow kits' which consisted of a metal bar on each side of the boot floor to the top somewhere in the boot. The first time I saw this kit I was shocked that they were needed in an Australian built car! They had 'bodgy fix up' written all over them. I love my GM products but it does make you wonder about basic build quality!
Silastic contains a mild acid that will promote rust. Don't use it! Use a sealant specifically designed for the job. Even some windscreen sealant.
