BIG PROBLEM!!!! Need some thoughts.
BIG PROBLEM!!!! Need some thoughts. Last night when I pulled into my apartment complex, my motor was making a light know from the lower end. Wasn't anything loud our hard so I figured I would look at it this morning and see if it would repeat itself. Well I start up the car this morning, and no knock. The car sounded fine, so I took off for work. It's about an 8 mile trip down the interstate to work. So about a mile and a half away from work, my car makes a little lunge and this rattling starts from the motor. I slow down and notice my oil pressure went from about 30psi to 16psi. I have one stop sign where I exit the interstate and then my last half mile of 35mph driving. When I stopped at the stop sign, the car felt like it was running on 7 cylinders and knocking pretty bad. I limped my last little distance and parked the car and as I parked the check oil light came on and the pressure went to 6psi. After it cooled down I checked the oil and has gone from clean last night, to black and lots of grainy metal shavings. Obviously something internal went, but what normally would be gone with these symptoms? I haven't been hard on the car in forever since there has been so much snow lately and it's my DD. The car did sit for 2 weeks over the holidays. I had my oil changed exactly 261 miles ago and made the swap to full synthetic. To me I am thinking I spun a bearing. I just don't know.

let us know!!!
Sounds like a spun bearing to me! Drain the oil and remove the filter and cut it open. If you find a bunch of copper/brass looking particles in there, it's definitely a spun bearing! (ask me how I know?)

Is the oil full on the dipstick? See if you have any leaks somewhere, and yeah 6k miles on it it wasn't time for it to go lol. You should have a warranty on that don't you?

Verdad Gallardo Oil is full, but nasty and as for warranty, it's covered on workmanship, but I am thinking I might have other issues after talking to some people.
Only if I was so fortunate. A spun bearing is nothing to worry about lol. Try throwing a rod through your resleeved block and oil pan while internally destroying the block as the broke rod flung around at 4K rpms....This is what I'm dealing with right now....arg.
Good luck on your car!

Here are the damage pics. #6 rod bearing spun. The #6 rod ground about .030 out of the crank in that position. All of the rod bearing were scored and as soon as we took the caps off the bearing were falling out. Not locked in place at all. All of the main bearings were scored and damaged. The best of all the mains, was the thrust bearing. The crank is ruined, the rods are more than likely ruined. The block came through with no damage, as well as the pistons.

Looks like a serious mess! If no other rods bearing had spun, you may only need to replace the one rod.
As far as the crank, thats scrap metal now. What shop built this? I would leave it where it is now, and then start some court actions against faulty workmanship. You maybe able to get it rebuilt on their dime by another shop.
Lol, you can't tell those are already forged pistons/rods?

You're the stereotypical American who gets all lawyer happy aren't you? You don't even know what happened to it, how long it ran flawlessly, etc and you're saying get a lawyer?
Jason, shoot me a line and we'll see what we can figure out about what happened and we'll try to help in whatever way we can to get you back on the road.

That's an awful lot of damage caused by one spun rod bearing. When I lost #2 rod bearing on my new build at 1700 miles, all it did was ruin the #2 rod.
The forged crank wasn't damaged at all and just needed to be polished.
Builder replaced the rod, all the rod, cam and main bearings, put a fresh hone job on the cylinders and replaced the rings. It was all done under warranty and now the motor is back in the car and running fine.
If you can, you should post up here about where the motor was built and what they are going to do to help you out! Good luck and sorry to see that mess!
