Was Vitesse throttle controller my engine seized ?
Hi.
My engine seized last week outta nowhere with no signs or explanation.As I literally was backing up of a parking lot when I heard a noise coming from the engine and oil was everywhere. I'm past feeling sorry for myself about it but still trying to figure out or at least have some explanation to what would of caused that. At least so I don't make the same mistake again. I've got 2 things I keep questioning myself about and was hoping some of you guys can help me eliminate or confirm my doubts. 1. When I did the last oil change I put 8 quarts in it, But when I checked it on the dipstick it was a little above the mark. 2. I installed the vitesse throttle controller last May and lately as I got used to it, I put it on 8 sport which is almost the max.Not sure if the high rpms from it could of done anything to cause the failure but is it possible ?

As much as I don't care about the VTC, its probably because you over filled the oil. Overfilling oil can cause the engine to seize.

I'm %100 sure I did not add more than 8 quarts. I don't understand what happened.

One thing for sure is the VTC has no role in the incident. Possibilities are one, an oil pump failure. Two the oil level was filled to a point that the crank throws were striking the oil and whipping air into the oil causing foam. When you get it torn down you will see where the oil starvation occurred and whether or not you have a pump failure.

Nope. Nothing to do with it.

Oil everywhere sounds like a spun bearing and broken connecting rod to me. We need high volume and 5-30 weight to keep our engines happy. The throttle controller has nothing to do with it except making it slightly more responsive and hopefully if your flogging the engine your doing it warmed up well. But that's one engine that will most likely need to be scrapped as a cracked sleeve on these blocks is a death sentence the sleeves are cast in. Good Luck to you though and let us know how the build goes in the future.
A spun bearing can happen and the results are like yours and that means the oil hole to align perfectly with the oil passage ways from the block through the bearing cannot penetrate and thus a unlubricated bearing eating itself up from friction and heat until..... the heat and stress, and from the slop in the bearing make the connecting rod break. Anyway that's my opinion it will have to be looked at on tear down, it could be many things but thats most likely IMO. I read about the long term tests of the new corvette in like Decembers motor trend and the LT 1 in it spun a bearing with in 7k miles sometimes its just bad luck..... They said they are working out the kinks of deburring the blocks better and the oil filters could even give off crap..so yes its usually better to go on the latter years of a engines implementation in a car as changes do occur over time that are really needed, Like the 2010 had several things that had to be fixed from fire hazard from the battery cables to other things. And our engine was still in use years before the Camaro gen 5 to iron out things better. Anyway good luck to you! And being a 2010 L99 I would be worried about the lifters at that age especially with AFM.....

How many miles do you have on the engine? Did CEL or any messages popup immediately prior to the engine failure? Ron |

I suppose it is possible if you changed oil on a inclined driveway, enough oil could remain in the pan to cause somewhat of an overfill condition. It would have to be so much overfull that the crank throws hit the oil level to cause foaming and in turn oil starvation. Only a tear down will reveal the cause.

My money is on a failed oil pump. He put the right amount of oil in, and assuming he used 5w-30, he should have been fine. Like 2sscamaro said though, only a full tear-down will reveal what really happened

Well now that I'm thinking about it.. Something wierd happened couple months ago. As I was backing up the car stalled. But it started back up with no problem. Then the same thing happened again a month after that. And in both times it happened when I was in a hurry and backed up pretty quick.. Not sure if it's related at all though.

When you say there is oil everywhere do you mean the seals have blown out and the oil is leaking out?
When I change my oil I do no assume that all 8 quarts is drained out and I can safely put in a fresh 8 quarts. I drain as much as I can and then add 7 quarts. The last quart I will check the dip stick and slow add oil and recheck the dip stick until it is where it needs to be at.
