Oil strainer gaskets do they need grease

Hi do i need to put grease on my oil strainer gaskets will multi purpose coma grease be ok as thats what I have any help appreciated

 

Can if you want. Or not. Your choice

 

Just a smear to hold them in place.

 

I've tried with and without, no difference.

 

Previous owner used a tube of silicone. Maybe 2.

 

Well, you don't want them to leak

 

...and you don't want bits of silcone sealant getting into your engine either - so use sparingly.

 

I just give them a smear of engine oil , works for me....

What the gap at the back of the sink lol

 

Just make sure ALL the metal surface are spotless, then use them dry.
Gently tighten the nuts opposite to each other. Torque the nuts appropriately. It’s a very low torque.
Do all that and it won’t leak from there. And use a new Sump plug washer/ring/thing…
