20w-50 to reduce oil loss

[Ozboz]

I have an old car that's on borrowed time but needs to last until the end of the year. The sump has become porous and leaks oil. It's a 1.2 Fiat and uses 10w-40 and I want to know if I can temporarily use 20w-50 to reduce oil loss. Is this extreme or will 15w-40 be sufficient. I don't care about car and it will be scrapped in December. Cheers xx

a new sump is like £40 and an hour to fit so just replace it

Drain the oil, clean the sump, then paint with fibreglass resin. Should keep you going until Christmas.

If the sump is "porous" and is leaking oil, then a different grade of oil is unlikely to help. heavier weight oil is usually a bit of a fix when oil is getting past the rings. If you have oil leaks, you have oil leaks.

I'd get a big tube of sealant and just smear it over the sump. Tigerseal maybe.

Can you suggest a suitable resin please....presumably one that can be "painted" on from underneath. Cheers

Any polyester (for glassfibre) resin or epoxy resin, but in both cases applying some matting will be 10x better.

Panda Sump £20 buy it now.

New gasket. Self fit.

Come on. Probably cheaper than ballsing it up with some painted on rubbish.

I think it would be easier to replace the sump than to clean the old one in situ well enough for any external sealing to have a chance.

The people who said "just replace it" are right. I cracked every bolt to make sure none were seized, including the manifold, and none were, so am going to buy a sump and get my hands dirty.

Just one question as there is no sump gasket, so what sealant is best to use?

Many thanks

No sump gasket? By design? I doubt it, Fiat sump gaskets are dirt cheap, use one with a gasket sealant and do the job properly

Fair enough, I stand corrected, only got old cars!
