I might have missed it, but are the pieces they found aluminum? If the pieces are metal, then you are in the clear.

But, I don't want to tell you this, but no matter how soft aluminum is, it still wreaks havoc inside an engine...

 

Yeah I know nothing like that is good. The link says its made of 6061 Aluminum (Dont know what the numerals are for) They may not know its aluminum though. How would I be in the clear if they are indeed metal? LOL.. they would pin that on me since its aftermarket.. and especially if its the blame for this noise.

 

If it's metal that puts you in the clear on it being your intake....since you haven't done anything downstream from the intake, it can't be your fault.. I would still want to see where the pieces came from if they insist it is from the intake.

The 6061 is aircraft grade al, it is built to withstand heat and it can be bent to some degree without cracking.

 

Ahhh.. ok

 

Ok, first of all aluminum is a metal, and second of all, the majority of the 2az-fe engine IS aluminum. The block, head, and yes pistons are all aluminum. The cylinder head cover is magnesium, the cylinder liners are iron, the con rods are steel. The crank is forged steel.

So, since the pistons are aluminum.... as well as the head, it is possible the shavings came from somewhere else. Something to think about...

Thanks for clearing up the matter Jowie... I wasn't thinking that the tC motor was aluminum...

Stu, good luck..

 

Yeah.. thanks bro! I will just have to wait at this point.. its out of my hands..

 

oh wow....

they are just trying to find someway to blame your aftermarket products because they are probably ____ed on working on it.....

if it did "come from the intake", did you happen to check inside the intake for any shavvings at all?

regaurdless if the pistons and head are aluminum, the only way shavvings can form there is inadequate oil feed.

i believe someone said oil pump in this topic, and you bring up a valid point, stu you might have been really low on oil

but i havea feling this will all be covered under warranty, there's just not possible way this was caused by an aftermarket product....just no way

 

There was flakes in the intake.. I went and looked myself. I am just out there.. I think it will be fine.. or.. i'll be broke.

 

How long has the intake been installed?

IF there were shavings from the factory, this problem would have started as soon as you fired it up.

 

The intake has been on for about.. ehh.. early summer. I am just skeptical about these flakes.. although they aren't good, what could they possibly do to create this noise.. I guess thats the answer they are going to put together for me.

 

How can they prove that it was the intake and not the engine itself???They are both aluminum..

 

True.. but they would have to also be able to prove what did it internally. If they cannot, or cannot give a reason why, then it falls on me.

 

Then inspect the intake to see if something has broken. If it hasn't it will be much harder to say it was shavings from what you did. I find it hard to believe after final inspection, shipping and installation, there would be anything inside the pieces you put on...

 

I dunno.. come to think of it.. better yet.. everyone that has the WR intake should take a look.. maybe that could be somewhat of an issue!

 

I just don't see how thru all the banging and bouncing of shipping and surely, you'd hear it as you installed it, you'd have to check out what was making the sound or you'd look to see where all that mess was coming from....

 

These are very fine flakes, not really large enough to be noticeable. They are "caked" to the inside and only are being removed when the intake manifold lets the air in.. or so they think.. I had to physically remove them with my finger to get them off. For what its worth.

 

Then you must have sucked a bird in to dislodge them...

Air alone is not that abrasive.

 

Yeah.. I surely think like you said, if I installed this thing and if there were peices that were large enought to cause massive damage, they should have fallen out.

 

Sorry to hear man...hope it all works out for the better (warranty) and not the worse (your bank account).....either way i think we are all curious, especially if this is somehow related to an INTAKE....unreal!
