Any easy way to figure out if the manifold is crasked or any tips?

So, what brand?

I have an 89 XJ that just turned 131000 mi and my last oil change a week ago I put in Gunk for high mileage and ran it for 5 min then drained and changed oil. Was getting small white globs on my dipstick i attributed to condensation since I drive 8 miles a day and my oil filler cap wasn't sealing at all (replaced). so far Gunk has gotten rid of that otherwise I don't know that I would have even considered it.

Also I used a quart of Marvel Mystery Oil for my lifters and my engine hasn't sounded this quiet since I bought it 3 years ago (with 118000 mi--i kinda stole this thing for what I paid for it). Usually use a bosch filter but Advanced only had STP that fit my jeep so I went with that and Mobil Super 5000 10w-30.
