Alright some background information. Engine has 171k. Heads and gaskets done 1500 miles ago.
Here's my problem, it sounds like a tick coming from the top of the engine can't pinpoint exact location. When it first started doing this my check engine
light came on. A week later my check engine light turned off and the noise disappeared. Check engine light hasn't come on since but the tick came back so I sea foamed my oil and changed it the next day and put in Lucas Oil additive (I use 5w-30). The tick went away for a couple days. Tick comes back and has been for about a week. It'll do it randomly though, sometimes while idling sometimes not. Sometimes when accelerating and sometimes not. Usually doesn't at cruising speed. Any ideas? It's utterly annoying.
No engine/performance mods (yet). Mach 460 sound system, 2 12" alpine subwoofers in a custom box w/ 1800watt kenwood amplifier. Smoked halo headlights, smoked sequential taillights, black bullitt staggered rims, racing stripes, and plastidipped spoiler. Future exterior mods - Chin spoiler, black fuel door, and demon fender flares (plastidipped).
