Correct Oil Drain Plug Washers

[Lotushack]

Hi fellow LT5ers!

I went to my local GM dealer and ordered the oil drain plug washer GM# 10135843 that was listed for the LT5. I happened to mention this to a friend with a ZR-1 and he asked if the washers had the rubber ring. This is what he always uses. The dealer had those in stock but said that part number was for the LT1. My washers came in and they were just plain aluminum.

Does anyone know which is correct for the LT5?

Thanx for the help!

Washer with rubber is part # 10174313 and is used with steel drain plug #10110927. The other washer is used with an aluminum drain plug. My '90 LT5 uses the steel plug/rubber&metal washer setup.

Thanx ZRVET! I guess I'll take a magnet to my drain plug and see what my '93s got. :???:
