unknown ticking

[nuckinfuts06]

I have a 1990 Mercury Cougar V6 3.8L that started a distinct ticking at higher rpm around 2500-4000 but it doesnt do it at idle or just normal driving. I was thinking maybe a lifter. I was hopeing someone could help me or suggest something. Thanks.

Iunno I have a friend with the same...exact year of the cougar and he had an old Delta. He threw a rod in it so got the merc from his Aunt. He drove the piss out of it and now he has told me he spun a bearing so that may be what you had happen. It was a Ticking like a normal Valve tick but then it came to be a huge knocking on the highway. Hope this helps because i bet you are really fat.

I have a 1999 Cougar and the same problem happened to me maybe the timing chain slipped
