I have a 2005 lgt with roughly 90k on it. I went stage 2 and ran a standard Cobb map for about a week. My brother was driving it on the freeway one day doing 65 (not pushing it) and heard some bad noise. I wasn't there, just woke up to the phone call
It was clear at that point the turbo was trashed- took it out yup. That was replaced and a new turbo was installed. We started tried starting it up and it sounded terrible.
Moving right along- I have bad scratches in the journals in the heads and on the cams. The block is seized (in the process of splitting). As stated the turbo was all play and not shaft. The oil pan is off and I found what I think is a wrist pin
I'm really looking for some help with a diagnosis as I would like to avoid this in the future. All signs point to lack of oil pressure- unless I maybe missed something?
Going back into my car will be a completely rebuilt ej257 short block, heads to be acquired yet?(just found out today machining will cost me about the same as just picking up new ones), and the newer vf46? Turbo.
I'll post my findings when I get the block split. This has just been a long emotional and financial blow. I'm just trying to get up and running proper again with some piece of mind.
Any help as to what could have gone wrong or head ideas or any useful insight would be massively appreciated.
-oil light never came on
-after taking apart the oil pump nothing looks weird there
-oil pick up looks fine
-the proper amount of oil drained out of the motor right before we pulled it
