the dipstick tube on my sump is leaking round the welded join. it was only drip here or there until the weekend, but now its dropping more for some reason. I know welding it up properly is the best outcome, but I have a racing event on Saturday and pulling the motor before then ain't gonna happen. Is there something I can work into the join until I have time to drop the motor?

Looking for a quick trick here.

JB weld is your friend. I love this stuff for fixes like this. Best left for 24 hrs before use. clean very very well.
