All new plugs torqued down. Been seeing vids of maybe exhaust leakCould be a lifter that never expanded.
When you checked the plugs you made sure they were all in tight enough I am assuming. The plugs are known to "tick" when they are not tight enough, just before ejecting and ruining your day.
I used Ford racing header gaskets and the flange gasket is from the Ford dealership.The passenger side header flange to the midpipe is always a pain. If you didnt use factory layered steel header gaskets and midpipe flange gasket, it is likely an exhaust leak.
So I should replace the header gaskets with o e peice oem gaskets?and get new bolts ?Man, I hope you get this figured out. Just like Thomas_W stated, that flange can be a pain! If youre useing the original flange nuts, the pain is greater for they were made jam nuts. I toss them in favor of stainless nuts. Lock each stud by useing 2nuts tightened together
Plugs are torqued to spec. Thinking it's a head gasket issue.When you did the plugs, did you use anti seize and actually use a torque wrench? If you didn't you might have boogered one and that tick is air getting past the plug which means it would be ready to blow out. Most Mustang PI heads only have 4 threads, they didn't get 8 till 2004 and even then they can still strip out.
Yep thought it was the oil filter adapter gasket, but after changing it and then flushing took er for a spin. Quart low and it's in coolant reservoir again. The pass side head was a pain the header and flange got stuck and had to be pried apart. Thinking it didn't seat rightDidnt you say oil in the coolant also?
I'm also getting oil into my coolant reservoirSounds like it might be the EGR tube. Probably at the header.

I think that is a separate issue. I was just referring to the tick. Unfortunately the oil in the coolant reservoir will almost certainly mean you are going to need to take everything apart and do it over again. That is if you cannot locate an obvious issue. If it was me I would begin by taking the intake back off and see if you have anything that you can easily see as an issue. But I am willing to bet you have a head gasket issue.

That's what I was thinking. Since the oil is being pushed into coolant ,it's not lubing the heads right. Thinking pass side is culpritIf the head gasket is bad it could cause oiling issues to the lash adjusters and make them rattle/tick.
