Silly sump plug question

[AndrewJames]

Hey guys and gals,

I am planning to change the oil on my 75 as the car came with no service history and only vague words on when various stuff was done. I don't tend to have copper washers spare so I thought I would just buy a sump plug that comes with a washer...that way I've got a plug if I ever need it and a correct size washer for this change.

I've reserved one from euro car parts although I don't always trust their website and have been stung in the past. This is what I've reserved: https://www.eurocarparts.com/p/sump-plug-333590081

Would this look right for a CDT? No information on size given but the only one that came up after popping my reg in...

Much obliged

Sorry don't know about diesels myself but DMGRS are usually quick to advise: cheaper too https://www.dmgrs.co.uk/products/sum...iant=303241171

Had a diesel for over 12 years now. Never changed the sump washer during the annual service. I think you'll find other members do the same.

Interesting. I am quite surprised to hear that. It goes against everything I've been told about not re-using copper washers.

Hi Andrew,

Maybe you've been speaking to people with an interest in selling you things!

Both copper and aluminium are soft metals. They will naturally form a seal when the sump plug is tightened to the specified torque. I have always re-used the washer which was fitted when I bought my car 16 years ago! "If it ain't broke, don't fix it".

My history too over the last 12 years or so however not only have I never changed the washer I have never removed the drain plug either.---



My Pela pump is perfection in itself.-------

If it’s not leaking now chances are there’s a washer fitted. If there’s a washer fitted there’s a very good chance that when it’s tightened up it’ll seal again. A few times now I’ve removed sump plugs only to find the plug without a washer of any description, no leakage either. Failing that, just drill a hole in an old 2p, be reet!

I’d you buy a genuine oil filter it comes with the correct aluminium washer.

I have a comline filter on the way but I was maybe a bit reluctant to admit that I shall see how it is and what's in the box!
