My Chevy truck came from the factory with a magnetic drain plug in the 5.7 engine. I have an extra one of these drain plugs, I wanted to use it in the GTO, seems like a good idea. Is the plug for a Vortech 5.7 350 engine the same as out LS2s?

On a side note, I just changed the oil and put a new PF46 filter on. The valvetrain was a little noisy before but now with the fresh oil I swear its quieter.

I'm not sure if the truck plug is the same or not but I have a magnetic plug for the LS2. Part# 11518377. $3.23.

Sweet, it is the same plug. I just thought it would be a good idea. When you change your oil, is there ever anything on the magnet?

Oh YEAH is there *ever* stuff on the magnet ! Like the stuff that comes out of your electric shaver, but metal, and a good fuzzy coating of it on the plug. Also, I found a magnetic filter shroud on ebay for $10 that fits over the spin-on, and will deploy on next oil change.

Coming from a hydraulics background, I can tell you that even a small magnetic trapper is an excellent investment.

Where did you get the oil filter magnet at?

I was told by a chevy dealership that the LS2 comes with a magnetic plug. The part # for the Z06 plug and they GTO plug are the same according to them.

Mine did not come with a magnetic drain plug. My dealership had tightened it so much that the head of the plug was kind of rounded off. I discovered this when I changed the oil and had to buy a new plug (the magnetic plug).

Aren't most plugs the same size for all cars?

Maybe this is a dumb question, but what metal bits are in the engine that wear and will stick to a magnet? It doesn't seem like there would be much in an aluminum engine. Also, what actually wears to cause metal shavings?

the inner surface of the cylinders and the outer surface of the pistons are steel.

I can give an example that will give you something to think about. I had a built 327 and for whatever reason a snap ring came out of a lifter and siezed the oil pump. If I had a magnetic plug that would not happen. You never know what you will find on that magnet.

I have a magnetic plug on my GTO I got at Pep Boys. Yesterday I did my first oil change since I installed the mag plug and did find some small amount of tha fuzz in the very tip, no more than 1 square mm. I do not know if that is small amount or a lot but I am glad it is gone and out of the engine.

Would you mind cutting up your oil filter the next oil change? I would be interested to see what is being trapped.
If I get one, wouldn't be till spring that I would change the oil again

We occasionally cut spin-ons at work, so I'll see if I can remember to do it and post up pics. Likely there will be the same fuzzy shavings in there. but more of them.

Bear in mind that oil in the sump has been repeatedly filtered and the magnet on a drain plug is fairly puny, and you still see trapped shavings. The spin-on magnet is a really good idea. We used to sell a "Mega Magnet" in our parts catalog for hydraulic use that would have put the magnet on JL subs to shame ... and it was popular.

SimpleGTO and his example of the lost snap ring is exactly why a magnetic trapper is cheap insurance. It can turn a catastrophic failure into a recoverable one - important if you're off warranty.

I thought the magnets were there just for the holistic purposes :)
