Hello guys, I'm new to this by the way so sorry if its in the wrong section.. Anyways I just bought a 06 tsx and it's modded. Has many aftermarket parts. And I'm kinda concern that the ex driver drove it a little to hard. It has the check engine light on, and it said "check emession system"

It has aftermarket headers, it has a hondata reflash, and a cold air intake. I just change the oil and filter and spark plug to a racing one and synthetic Mobil 1 oil. Reason why is because there is this noise when I start the car that sounds like two metals pieces scraping each other reall fast and loud. It's only on cold starts for the first 3 or 4 seconds of the car starting. If I turn it off and on it won't do it. I have to let the car sit an hour or so.

I asked the previous owner and he said some bs about that he fixed the timing belt to a racing one and that's why it does that noise that I shouldn't worry about it. -_- sounds like bs to me, plus we didnt leave on good terms so I'm worried he just want my car to **** up. Lol anyways, any body have any suggestion on what the problem might be and if I should fix this. Maybe he was right and I just didnt know that the noise is normal. Idk, it doesn't sound normal. HELPP!!!

Also!!! "Check emession system" should I be worried about that??

does the sound come from the engine bay? or under the car?
did you check you o2 sensors?

Any check engine light is never good. Go get the code read and post it up or check online. Also, the 2006+ doesn't have the "hondata reflash" from what I remember. They have Flashpro which is quite pricey, so if your car has flashpro, then that's a plus. As for metal scrapping, that's never good. I've never heard of a "racing timing belt" for our cars... especially since our cars have timing chains... and rarely need to be changed or upgraded. Maybe check the tensioner.

Looks like a lot of BS the guy said to you. Did you not have the dealer or a mechanic check it out before you bought it? It's always a good idea to do that...

It is BS. You don't have a timing belt, one. Two, the sound you are hearing is associated with your Timing Chain. I can guarantee 100% that the sound you are hearing is the timing chain tensioner. It will sound like a rattle and only happens on cold starts about once a day. It has to do with it not retaining it's oil pressure till the car is started. It can eventually fail and hurt your engine. I would replace it immediately.

Timing chains r a PITA to change. Stealership charges 1500-2000. I say return the car

Yeah I think your right bro, plus this was a little Asian kid who had to sell the car because he couldn't finish paying it off. He did so much stuff to the engine that I don't know half of the stuff in it. I just know the basic CAI, headers, reflash, exhausts, he has a spacer between the CAI and the engine. If this noise is coming from the timing chain, how much is it to repair, and what could happen??
