Found the source of a leak thats been staining my drive for a few months.
A hairline crack in my sump where something has scraped along the bottom. i can wipe it clean and within 2 minutes, a new film of oil appears in the gouge.
My question is, can this be repaired with Araldite or Liquid metal / similar products.
Should i drain the oil first or should it be alright? ( will wait untill its cold if leaving in as it only drips when its warm )
Thanks in advance

I'd say you would be better with chemical metal if anything
Edit: do it when it's not leaking so it doesm't stay oily

Have used some stuff before, not sure what it was but it was like a putty that you worked in your hands for a few minutes then it sets hard. Think it was wurth stuff and worked fine. Just drain the oil and make sure it's well degreased.

No idea to be honest, I'd imagine you could get a cheaper alternative or something. That's just the first result I found on google.

they sell similar stuff in poundshops, about the size of a marker pen lid, knead it together for a bit and they set hard, worked ok on my fibreglass boot lid on the spoiler holes but not sure how it would work on the sump, worth a quid though?

Would use chemical metal TBH, used it on my diff casing when it cracked and held up for ages, id take sump off and dry it as much as you can then heat it up with blowtorch to get all oil out of the crack otherwise it will never work 100%

its like a stone gouge on the flat bottom of the sump. its left a groove and its just managed to skim through to allow the tinyest amount to seep out. doesn't do it when the oil is thick and cold.
if i fill the groove with that putty, as long as it holds on to the sump, i think it will seal it

Would need to be 100% oil free. Whip it off and get it welded imo

Id take the sump off personally and heat it up so you get rid of all the oil, wont have a problem using chemical metal or similar on that tho, mine was an actuall hole i filled with mine about the size of a 5p

That'll repair easy enough, just make sure it's really clean and then rough it up with a bit of sandpaper.

could taking it off and heating it potentially make it worse? not really a great idea to have the crack expanding and contracting.. i'll drain it, pepper it with brake cleaner and keep coming back to it throughout the day.
