[QUOTE="Ashlander, post: 15260319, member: 166914"] Just got a 98k mile motor from an 03 Mach 1. Turns over good, and didn't see any metal or coolant in the oil (they didn't drain it before shipping). Was told it ran good and got good compression, but never got around to getting the test numbers. It's pretty dirty, but haven't seen any signs of leakage. I was planning on removing the timing cover, valve covers, and oil pan at the very least to look at the timing components and inspect the bottom end before putting it in the car. I'm on the fence of whether or not I should take off the heads to check the cylinders. I've heard people say they wouldn't even think about cracking the heads on these motors unless there were signs of a major failure. Wondering what other people's thoughts on this was. Obviously if money wasn't an issue I'd just play it safe, but just removing the heads will run at least another couple hundred just in gaskets and bolts, which could go towards headers or a tuner.
