The engine going back in is a rebuild of the old wet sump 454 I had in the car. That engine lasted two years with a lot of miles. It had some oiling issues, along with some other things. I kept waiting for it to blow up and it wouldn’t. I finally pulled it after it fouled a set of plugs in 150 miles. Two of the pistons were missing corners, haha.
It’s always difficult to tell what factor(s) and it can be multiple, were contributing to the failure. Because of this, I always make sure all of the oil lines and cooler are checked and cleaned and also send the injectors out. We also had a bad coil pack, so I replaced the whole set.
