engine noise,knock, goes away
 

i tried to localize it using a hose to listen. it starts as a fairly load knocking sound but goes down in a few minutes. i havent had a "knocker :in a while so i cant figure it. is it lifters/rockers?.
its not ticking like exhaust will do,its metalic.
gets almost silent, and always runs smooth

i cannot localize it but it almost sounds outside the engine, a knock/click, that goes away slowly as it heats up.
the "hose"listening works and i hear no knock in the oil inlet or on in/ex manifolds,valve cover.

Have you ever heard piston slap?

? i dont know? is that my description, it goes away in a few minutes?

Definitely sounds like piston slap. My old motor had it bad. Simply put the piston has worn down and it moves around in the bore when it's cold, once warm it expands slightly and fits better, and the knocking goes away. If it is this, the knocking should also go away when the engines under load as it stabilizes the piston. Do you have oil consumption? Any oil in the intake filter? These are also signs of this.

no oil trouble or excess use.it sure sounds like it though.danger?
how long b4 real trouble?

That is difficult to answer. If it is piston slap and you want to fix it is a rebuild plus machine work. IMO if you did a compression and leak down test with poor results plus had excessive oil consumption then its time for an overhaul. But just piston slap I wouldn't bother.

not something ive had b4 so i dont know what to expect. it feels just normal and quiet when warm, a few minutes now, winter?

how many ? does not sound like all 6!!

I'm not sure what you are trying to say. If you retype or edit we may be able to help you

Just drive it until it blows. I drove 80,000k with mine before i pulled it. It had got so bad that it knocked at idle even when it was warm. And even then, I pulled it because i got a new one, not because the old one had blown up yet

i think thats the plan! thanks

It's a roll of the dice. You may get away with it for a while but if that skirt breaks then I recommend getting a super heavy duty oil pan to help hold all the sheeet in :laughing:...

im learning! thats what im here for and i can se your point. thanks
