Really Loud Ticking When Driving

[unreal808]

If one of the HLA’s has collapsed,
you really wouldn’t notice it visually, witch could be the problem.
But lower end engine noise like wrist pins could sound like a collapsed HLA. But I don’t know how the “Loud Ticking’’ noise really sounds like and at what RPM. a lot of things cause ticking like ignition timing off, low oil and so on.

And you could have outstanding cylinder compression and pass a leak down test and still have a bad bearing or wrist pin. I have driven some cars that for the most part ran like a champ with only 10 thousand miles deep, and pop something loose In the lower end.

I hope its not somthing to serious.
