you'v all heard this many times before but lets try n give myself, being a newb, a chance..kinda intimidating on the forum, but i've been doing the search mode and have come across several sound/video clips (but they dont match my quality of engine knock)..also been reading posts but have a few questions that i havnt found answers too

first of all..bought the car about a month and a half ago...but realized there was a engine tick/knock/whatever almost a month ago..i dont know if its always been there or developed..i cant remember recognizing it the day after i bought it...

it only knocks when cold..doesnt knock when idle..but when i rev it does..and is worse around 2000 rpms..and goes away ocne the engine reaches normal temp..

this is a NEW engine..the valves were recently adjusted (few weeks ago)..but the knock is there...there are no oil leaks to my knowledge..and use mobil one synthetic...its due for an oil change at the end of this month...

the knock is like a clack clack clack..and isnt very consistent..if it IS a piston slap..it sounds as if it slaps on random revolutions..not on all and doesnt sinc with the revolutions of the revving (if that makes sense)

my questions are

1.) will a thicker oil tame the knock significantly while i find the problem? (im thinkin of doin an oil change this weekend just to see if it'll help)..

2.) has anyone experienced this before?

3.) is an oil test a good idea worth its money to get some kind of diagnosis?

4.) i once heard these engine knocks were normal..explaining..that the pistons just needed the time to expand and reach normal temperature and dialation...and that it didnt do further damage to the engine..could this be true

i'll try to get a sound clip up soon or a vid...

sorry for my newbness..just want some guidance

 

unrelated..but someone just broke my back window with a brick haters

 

anybody?

 

damn..100 views and not one response?..hard for n00bs to get some love around here isnt it

still pissed about that f*cker who bashed my back window in..

Internal engine knocking is not good. Could be valves, pistons, spark knock. Do compression and leakdown test and whatever else test there is to make sure internals are ok.

 

hmmmm well for starter how did you "rebuild" this motor?

if you did a ball hone and piston swap I can almost bet its piston slap. but thats just my $.02 the unfortuneate thing is if im right u have to go get the motor rebored and honed and get a set of OS pistons

well good luck to you, and sorry bout the haters
