Oil Drain Plug Crush Washer

Recommended Posts

Ok I got a handful from FCP, some are copper and some appear galvanized aluminum looking, are they the same or are the silver ones reusuable and the coppers not ? just dawned on me Monday during the change ?

I use Aluminum.

Crush washers aren't meant to be reused. They are soft metal that crushes to make a nice tight seal with the microscopically uneven surface of the oil pan. Presumably you can only crush them once.

My indie Volvo mechanic tells me the copper washers are for the red block engines while the shiny washers are for the white block. I also read on one of the Volvo boards using the wrong washer on a white block could result in a leak from around the drain plug. It doesn't take as much force to compress the shiny washer (and seal the area around the drain plug) as it would to compress a harder metal like the copper one.

alum for alum oil pans (white blocks), copper for steel oil pans(red blocks)

never reuse a washer, always torque the plug down to spec (never more).

OMG you are soooo right, it's not even funny :angry: I found a copper on a white block today and I had to use a chisel to get the drain plug on, the different metals didn't get along to well.

I used to replace the crush washer every other time I do an Oil change, however right now i'm using the same one, i'm on my 4 th change with the original. The alum will get more uses than the copper.

I do not reccomend re-use of the alum wsher during oil changes. what happens when the washer loosens up the plug and THERE GOES ALL YOUR OIL!!!

YAY! new engine!

Can you get any smarter? I love finding rubber ones that Jiffy Lube put on.
