Does anyone know what part the GTO engines use to block off the oil dipstick hole in the LS1 or LS2 block ? I'm using a GTO pan on my conversion and need to plug the standard dipstick hole in the LS1 (Camaro) block.

Or can someone with a GTO engine Email me a pic of that area? What's plugging the hole?

Thanks

Its just a mini freeze plug.

Is there a GM part number for it?

Measure the hole and go down to the parts store and get one, why pay the dealer $10 for a part that will cost you a buck, at the parts store

This is an aluminum block that expands differently than a cast iron block that uses freeze plugs. So the rules of freeze plugs and holes sizes may not apply here. That's probably why the LS aluminum blocks don't use freeze plugs, but screw in plugs instead.

So does anyone know what the GM part number for that plug is??

Lots of Aluminum motors used freeze plugs, wait until you get it and find out its a steel freeze out plug

It is, I knocked mine out to use a H3 pan. Didn't think to keep it.

Heres from my post in the G-body swap thread on my 05 LS2 GTO motor that I put a caddie CTS-V pan on..

One of the issues I ran in to swapping the GTO pan to the CTS-V pan was the GTO pan has the dip stick hole integrated into the pan. What I found was that there is a plug that you just need to tap out in the LS2 block with a punch to use the CTS-V oil dip stick..







Also found a thread with a closer image.. Cheers!

is this the right one to use for an LQ9 dipstick hole as well?

I'm putting mine into a VY commodore which has the pan dipstick hole from factory, so using that.

thanks in advance

It will fit all car and truck motors. The plug is not specific to GTO engines, it's a plug that fits the standard dipstick hole on all engines. It's only GTO-related because the GTOs are the only engine (that I know of) that plugs the dipstick hole in the block and instead uses a hole built into the GTO oil pan.
