What oil do you run?

Castrol GTX 5W-30 with a Fram Tough Guard filter. I was told on another forum the Fram is a really bad filter to run with the 4V. Also, I was told by the previous owner to not run synthetic till it hit 50k miles (currently at a little over 48k) since the engine was rebuilt not long ago (mileage-wise - year-wise it was 2008).

I have heard bad things about Fram and their anti-flow back valves on the filters. I had a similar sound on my Jeep Wrangler when I ran a Fram once... switched back to the Mopar one and the noise went away.

Really? That's what the other person said. Seems like its the first step I need to take. Is it likely that something is damaged or am I probably okay? It hasn't been happening for too long.

I have never heard anyone say they had damage from this, but it probably isn't "good" for the engine.

I would think it is just a cheap first step to troubleshoot. Quart or two of oil and a new filter is less than 30 bucks.

The whole mileage thing is BS. You can use synthetic whenever. Switch to a Wix or OE Ford filter see if it helps.
