SH sump plug quick question.

[PRTVR]

Just recently done an oil change and when I removed the sump plug, there was no washer on it,
Is there or should there be a separate rubber washer on the Steve heath magnetic sump plug ?
Thanks

This might help, scroll down a bit to the post from "shpub" ...... sump plug seal

You need one of the copper compression type washers for a good seal. Rubber tends to squeeze out as you tighten.

Find the right size Dowty seal (bonded seal) https://www.ebay.co.uk/itm/Dowty-Washers-Bonded-Se...

This is a seal in two parts an alloy body (which would likely seal in its own right) plus a rubber lip seal bonded to it.
In use the bolt tightens nicely against the alloy body and at the same time compresses the rubber seal. The alloy body prevents the rubber from being crushed.
