X84GNB 2.5 petrol V6 manual estate
I have changed the RH exhaust manifold, reassembled, and suffered coolant leak due to missing coolant transfer pipe O ring. Dismantled, replaced O ring and glued it in place, reassembled; refilled with new coolant, started engine, observed coolant flood at back of engine. Stripped it down again, discovered one of the coolant bridge bottom washers was absent.
I have four spare washers from my earlier assembly. They have been inserted once, torqued up, then replaced after earlier leak. I know I should buy new washers, but I shall not get any before Tuesday. Would I be daft to reuse the spares I have?

i would think you may get away with them tbh. just my opinion of course. :)

I cannot remember whether they are solid metal (aluminium or copper), crushable metal, or metal with a ring of rubber bonded to the inside :-\

They are a metal ring with a rubber ring bonded in the centre.

If the rubber inner seals look un damged, then I'd refit them. If torn or nipped in any way, binem.
...rightly or wrongly. It is just the rubber that seals these I thought, they're not a crush washer as such...?

as above. they are metal with rubber ring. :y

As Chris said - if the rubber is undamaged they are good to re-use. What you may find is that the rubber has gone hard in which case it is your call whether you think it is still elastic enough to form a seal.....

Personally I always fit new - but in an "emergency" I guess its your choice whether to rebuild with a used seal. At best it will work out ok, at worst you'll end up doing the job again to fit new seals!! For what they cost, imo it's a no brainer ;)

I refitted the used seals last night. This morning filled with antifreeze and started up - no leaks!
I appreciated that for £10 buying new was the wise course, but I was impatient.
Thanks to all for advice.

Hope they hold up ok for you ;)

At least not that hard to get to if they do fail, so I see it as no harm done TBH.
If they looked oviously damaged, I'd just replace them as a matter of course, even if they appear to be water tight now.
