qr25de questions..
Soo just out of curiosity anyone ever had a qr25 die on them due to the pre-cat or any other issues? If so what are some signs that its time for a new engine other than it obviously not starting lol.. And also what are some signs that the pre-cat is the culprit? Thanks for all your help.

The burning oil is the main sign of the precat failure. Pieces get ingested in the motor and ruin the rings, cylinder walls, and pistons, can also slightly bend valves depending on the size of the pieces. There are also the butterfly screws if they havent been taken out and loctited that can cause severe damage.

If its trying to start and doesnt want to stay running Id do a compression check. If it just doesnt start at all or try to I would still do a compression check but look for other issues that would cause it.

If it sounds like marbles are in the engine, it probably ate the cat. It was a free warranty repair if you car fell into the offending years, it could have been fixed for free.
