This came out of my dads 2000 WS6 when changing the oil. It was stuck to the magnet drain plug so it is a metal piece. It is very hard to bend and to me looks like a ring? He has had very bad luck with Vortech superchargers in the past. He has had 2 units fail and is on the 3rd good one and the car has 12,000 miles on it. I was told they had a bad batch of bearings when they first came out with the V1 SC model? Each unit would last for about 3000 miles then get loud and the bearing would come apart?
Could this be a part from the past superchargers that may have come apart and settled in the oil pan? The car runs fine and does not smoke and still has power so I am confused on what it is? We wanted to go run the car this weekend but now it looks like we are going to pass.

 

It can't be from the blower, it would not be able to get past the piston and rings.
Is the oil pressure still the same or has it dropped a little lately?

 

The reason I think it may have come from the blower is because there is a oil return line that goes back to the pan.
If some parts came from the blower and went down the line it would end up in the pan? I am just grassping at everything to figure out what it is.

 

Is it a piece broken off the end of the dipstick?

 

all ur valve locks in place??

 

looks like part of a chewed up ring to me....

 

Oh ya, it go through the oil tube sorry
I was thinking ring too, but it doesn't smoke??

 

No smoke does not use oil and does not rattle??? Keep them ideas coming guys. It is not a valve lock.
Looks like part of a chewed up ring to me also.

 

possible valve spring chunk... any ticking?

 

I vote for the ring.

 

no ticking.

 

Ummmm, looks like a DIME to me.

Seriously though....Looks like a chunk of a ring to me. Don't know how it'd get in the oil pan though unless it's a piece of the oil ring.

 

I don't know, most rings aren't flexible enough to bend like that... Tough call though, doesn't look like anything that should have been installed on an LS1 motor to begin with

 

looks like the little thingy on the end of a spark plug dunno how it would get in your oil though?? hehe

 

OMG, are you saying he hasn't changed his oil from the inception of his first blower install? I'm going to say it's either part of the oil pan where he tapped it for a drain back or possibly a piston pin retaining ring. I forget if the LSx series has those or if it's press fit like the old motors?

 

Well you can tell it was some sort of ring because both ends have similar breaks showing that they were mated together. As for what it goes to... pretty sure it didn't come from the internals of the engine. I'd try to find the Vortech parts breakdown to see if you could track that part down.

 

Right now I'm thinking that if he hasn't changed the oil, it could ALSO possibly be a retaining ring from inside the blower. The blower drain line goes back to the oil pan and wa-la...broken parts in the pan.

 

The oil has been changed several times since the first blower came apart and the second one started making noise because of bearing failure. I think that is a good idea on getting a parts breakdown of the blower head unit. I don't think a ring could bend that much without breaking?

 

does it have stock rockers????? it looks a little small to be one of those bearings but poss a blower part.

 

I dont much about the insides of the blower. But i worked in a race engine machine shop for a while and it looks to thick to be oil ring parts (oil rings have 3 pieces two very thin rings sandwiching a wavey ring). Oil rings are very flexible, its the top 2 (the compression rings) that are very brittle. If the oil rings are good its hard to get a piece of the top rings into the oil they usally get into the intake. If the LS1 has floating pins the retainers are very thin, either spiral locks or snap rings.
