New KA sump - is it difficult/long job?

[nitten_traveller]

Mrs N's 2013 KA recently started leaking oil quite badly.  It has been diagnosed as a porous sump and needs to be replaced.  The quote to replace is pretty steep and I'm told it's mostly labour as getting to the sump on a KA is not easy.  I just wondered if anyone has any experience of doing this or how long it generally takes?  The garage reckon it takes several hours hence the high cost (north of £400!).

Petrol Ka is 2.8 hours and diesel 2.0 so yes, quite expensive job at a garage.

Thanks for that.  Looking at the invoice they don't itemise the labour per hour, though it's a hefty chunk.  Most expensive part though is the sealant!  Apparently it had to be ordered in specially.
