Sump 'crush' washers - a lesson learned

[Welly]

Actually a previous bodg....err....expert fitment proved successful with a quick flash over with Brake Cleaner and speedy application of gobbo it held up for a year.

Seems to only leak when the oil's hot.

Hoping some Instant Gasket will be a bit more suitable than clear construction silicone

Hoping some Instant Gasket will be a bit more suitable

It worked!

A slightly weeping brand new washer, cold engine, a quick flash over with brake cleaner and speedy application of 'Hylosil' Instant Gasket around the outside surface (washer/sump).

One test drive later and it's bone-dry

Well done.
The problem is the temperature cycles and different expansion rates of the materials involved, so you need something 'flexible' to cope.
Hopefully you've nailed it.

However all these oil changes will be adversely impacting the environment, (just saying).

The I-G is non-setting so I expect it to move a bit with expansion but am confident it will stay sound - it was applied to recently sanded smooth aluminium and completely de-greased thanks to my new found hobby of dispensing Brake Cleaner

I was ecologically compliant by reusing the oil each time so nerr

I'm not throwing away 10-mile old oil for no-one

Relieved to hear it.

Gonna invest in one of them syringy thingies next time I own something worth changing the oil in.
(If I changed the oil in the Cistern I'd probably be dumping the most valuable/functional/visually appealing* part of it).

Camper was serviced at a well equipped workshop with all the toys - vacuum oil removal system, (though we did remove the sump plug too to make certain it was dry). Also had an oil dispenser like a windy-up airline you pulled down from the roof. Preset to 6.5l, poke into oil filler orifice, press button, beeps when it's done. Magic. (You can't actually pour any oil in without dismantling half the interior).

Phew, yes that is a relief. I was worried it would go down the "still won't seal, drain sump, apply instant gasket, still drips, how the hell do you get these sumps off, use a flamethrower?" route.

A lovely chap called Mika does all my oilchanges now It's a change from my old days back in Blighty, where the parts were cheapbut the labour was expensive so it was all DIY. Plus it saves me the "I need to get a part but my car's in bits - help!" moments I had when I was first here.
