Wires not covered in looming

[ericem]

Is it important that they are covered? I found on the side with the coolant tank a bunch of the looming cracked and had fallen all over the top of the block. I goes right over the coolant crossover pipe and was resting right on it. For now used some rc car fuel tubing to space it up from the crossover pipe. Pretty well from that area up to the coil, iac and w/e else it seems to go to (possibly knock sensor?) it is exposed mostly. Should I reloom it soon or not worry about it? Most of it probably broke off when I first got the car and washed the engine btw.

Yes, reloom it. Just get some split loom tubing and some zipties, cover it back up, and attach it to the intake manifold. If you don't, you're risking facing weird hard-to-diagnose electrical problems down the line.
