broke

Hello everyone

I've been changing the oil on my '98z28 with 47,000 miles for about 3 yrs, and recently put a new, plastic washer on the drain bolt instead of the metal one which was sorta worn.

The washers



Today when I changed oil, I noticed the new, plastic washer was smashed flat and may have actually damaged the soft rubber lining inside the oil drain plug. What happened...and is this bad? Do I need a new drain plug?



Close up of the drain plug, not sure if you can see the damage

Looks like you need to order a new plug. That extra piece you added ripped out the original washer.

thanks Venom, I did buy one today for about 3 bucks and change.

should I put in a new, plastic washer?

l'm worried it will flatten out and damage the oil plug seal

is it harmful to put in the oil plug without a washer?

you should only use the factory rubber washer and throw away the plastic one. the rubber one seals better as long as the drain plug is factory.
