Help!

I have split a seam in the Chummy's perol tank - does anyone know of a temporary repair?

TIA, David C

Hi David, Guy tried some of that tank sealant when he did the same thing to his. I think it worked OK, but his long term fix was to have my spare tank!

David,

In the States, there's a 2-part epoxy product called JB Weld. Actually, there are two versions -the original JB Weld and one called JB Quik Weld (their spelling, not mine!), the difference being that the latter sets up in about 4 minutes so fast application is called for. If this product is available in the UK, it should do the trick for you.

I repaired a large area (most of the back panel and one end panel, in fact) of an MG TC gas tank by spreading several thin layers of JB Weld over what was, at best, metal rusted to a cheesecloth-like state. I also used it on the seams which were leaking. (This, by the way, was not an attempt to cheat a customer by not doing a proper metal repair- it was more in the way of an experiment to see just how good JB weld really is and to save an otherwise junk tank.)

Several years later, the tank still holds petrol with no leaks. If you cannot find JB Weld in England, let me know and I'll post you some.

Tank sealants are great for weeping leaks but aren't structural so won't stop a split extending if there's a force working on it. You have to take a judgement on situation

I used some of the pour in stuff from the Complete Automobilist and that has stood up to 4 seasons of trialling. I did try assorted gums on the outside but had problems getting them to stick to the solder.

The proper way is to have the tank re-soldered. When I took mine to a specialist for a quote (£80 from memory) he told me that the only way to do the job properly was to re-solder the whole tank. If you try and do a spot repair you end up chasing the leak around the tank.

The tank I have in there now is my original - Pete's is up in the loft if you need to borrow/buy a spare. I cannot remember if that was afflicted by the same problem though.

Is there any problem with doing a solder repair after using a slosh sealant?

I don't know as I haven't tried. I would guess that you would burn off the sealant in the soldering process. I would suspect also that there would be a significant risk of contaminating the solder joint with the sealant - short of taking it all to bits and sand blasting the sealant off the inside.....

Hello Guy,

Nice to hear from you - I gather you are now in Claybrooke Magna. Thanks for the offer re Pete's old tank, but I have stopped faffing about and taken my tank to Warwick Radiators in Coventry to be repaired properly. I also took the radiator in for them to see if they can clean it out a bit. I stupidly used some Holts Wondarweld to repair a crack in the block (that had opened up after c.40 years after having the block cleaned thoroughly) and this has blocked the rad core so that I can only do about 30 miles before having to fill up with a gallon of water. OK for short trips to take the kids to school, etc, but a pain in the neck on the Coast to Coast last year.

Cheers, David
