Knocking noise
I have a 04 STI. Motor started knocking a while ago. Was just wondering if anyone knows any shop that could diagnose and fix my car. If anyone can refer me to someone that would b great. I think i probably need to rebuild or drop new motor. Thanks.

Just saying that its knocking is very vague and can cover a blanket list of possible problems.
Record a video with good sound and post it up. Any other symptoms like loss in power, metal shavings in oil, increase in vibration can be helpful in diagnosing.

I'll post a video I lose about a qt of oil a week. Didn't check or pull anything apart yet. Trying to find someone or a shop that can do it. Just don't know who to take the car too.

It could be Mr Opportunity.
Sorry I didn't see that you said there was white smoke.
That changes a lot.
Take it in and ask for a leakdown test.

Yeah white smoke and sound is not good, but each by itself is not necessarily bad.
I was thinking at first it could be the tensioner pulley bearing. Mine went, and I totally freaked out and thought it was a spun bearing.
But the combination of smoke and knocking sound doesn't sound good.
It could still be a bad turbo. I've seen one with so much shaft play that it made a noise, but I doubt it.
