engine knock

[2gud4u]

mga sir pa help naman po nag kakaroon ng engine knock yung civic ko kapag nag aacelerate ako o kaya kapag mabilis na yung speed tapos bibilisan ko pa ng konti(100-120kph) o kapag nabibitin sa akyatan.

mas malakas po yung knock kapag mainit ang panahon 5deg. up, kahit gamit ko na po yung pinaka mataas na octane nag engine knock parin, pero kapag malamig yung panahon mga -5deg my engine knock parin pero bihira ko lang marinig

nawawalan din po ng hatak pag ng eengine knock

anu po kaya posibleng dahilan bakit nagkakaroon ng engine knock yung car ko


btw civic 2000 yung car ko d16 engine

thanks

It is best to take it to a reputable shop that specializes hondas so they can scan for trouble codes.Maybe theres a vacuum leak, faulty sensor,exhaust leak or a dirty injector/injectors.Worst could be too much carbon buildup within combustion chambers.Madugong usapan na kapag tatanggalin ang cylinder head.Check ignition timing first,baka eto lang ang problema.

My guess is you have a faulty knock sensor or worse a spun bearing.
Pa gawa mo na agad kasi ung sa kapatid ko nasira knock sensor nawasak ang buong makina.

thanks po sa mga reply,,, papacheack ko sa friend ko yung knock sensor pero siguro pagkatapos na ng winter, sa ngayon ok naman ulit ang takbo kasi nsa -10 ang temp. pero kapag uminit ulit lalabas na naman yung mga problema like pag nasa highway ako tapos speed ko 100 then slow down to 60 tapos pag mag aaccelerate ulit ako kahit naka baon na yung gas hindi parin ng rerespond yung engine tapos meron pa akong naririnig na knocking sound

additional peroblem ko pa po pla, nag babawas din ng oil yung engine, kahit wala namang leak

THats not a faulty knock sensor as it went away during winter.Knocking should be there no matter whats the temperature outside.Its not advisable to just guess on what part is causing the problem.Let it be scanned for trouble code.

is the knocking sound like a bunch of ball bearings contained in a tin can?

yup parang ganun po yung tunog

The MAF sensor is probably faulty.Try cleaning it by spraying electronic spray cleaner.You can watch it in youtube on how to do it.If problem still exist,then it is more advisable to bring it to a shop as they have the right tool to do the job.

sir kung faulty po yung map sensor,, hindi kaya dahil yun sa air filter ko? K&N drop-in filter kasi yung nakalagay

[dagol]

The oil you use for the filter might be the culprit.Original air filter is still best to use for EFI engines as it can trap dirt better than free flowing filters.It doesnt need oil treatment hence no oil contamination to MAP or MAF sensors.A lot of issues with the use of aftermarket tuning air filters.
