Strange knocking when I start

Thanks everyone for the help. I will go to the casa now to have it checked (better safe then sorry). Balitaan ko nalang kayo. Thanks again.

Sige, check ko. Thanks.

Hey guys, I sent my car to the casa na, they can't find anything wrong. Ang sabi nila the only thing that could cause the strange knocking sound would be carbon build-up sa intake ko. Have any of you heard of carbon causing a knocking sound sa engine? Hindi ko tuloy alam kung niloloko ako ng casa o tama sila.

tingin ko ay normal lang yan for cold engine start-ups. advise ko lang sa yo, na huwag mo na muna ipakalikot ng ipakalikot yung kotse mo ng wala naman talagang sira. you mentioned kasi na twice mo lang naman narinig within 2 weeks. and to back it up, casa na nagsabi sa yo na wala naman sira. sayang lang pera mo.

Weird lang kasi ang lakas ng katok sa engine. Now, i'm no expert pero alam ko hindi normal yung katok sa engine even during start-up at cold engine conditions. Hindi naman sa pinapakalikot ko yung engine araw-araw, in fact now ko lang sir pinagalaw dahil sa knocking.
