Changed out the oil filter housing yesterday. Took me about 4 -5 hours, including one little snag. I could not get the 2 sensors removed from the factory plastic part. I don't have a bench vise and using two 12" wrenches did not give enough leverage. I took the part to a local auto shop and their mechanic used an impact wrench and got them out easily. Over-thinking that a bit, and I hoped the impact would not have damaged the sensors from vibration. Placing all the parts back in, it seemed like the new cast aluminum part was wider, and at first it did not fit easily between the heads. Jostled the part around a bit and it did finally drop down into position. Refilled my coolant, started up, and sensors are functioning just fine. Went for a test drive. Oil pressure cold was 70-80 psi, then dropped to around 40 psi after warm up. Glad that the EVIC display has that available to monitor. I'll keep a close eye on it for the next few days and watch my coolant level as well.
Glad to have that problematic plastic housing out of my engine bay. The mechanic at the garage mentioned that they change these all the time, and, not just on Chrysler models, as other makers have gone the same route and used plastic. He asked if mine had the leak yet and I told him that I was doing mine preemptively.
Will follow up here if I run into any problems.
