hi guys.. need your expert advise with regards to my car engine.. this happened last holy week.. pag umabot na ako ng 105km/h na speed may naririnig ako na parang may belt or loose or parang may na ipit na ewan ko na medyo malakas na sound galing sa engine (rattle sound) .. tapos nawawala pag less 100km/h na speed ko... then i tried it again.. nawala siya bigla so i went up until 110km/h tapos bumalik na naman yung sound... any advise para before ako magpa checkup sa mekaniko.. me alam ako kahit konti... mga expert diyan.. tulong naman... :D

wind drag cguro. yung sa adventure umuugong yung roof rack pag 120 kph, pag lumapas ng 125 nawawala yung sound.

fierari,

sa may engine kasi galing yung sound not sure if sa engine nga pero sa loob ng hood... na conclude ko lang na galing sa engine kasi nga if i increase my speed pagdating ko ng 105 or 110 km/h doon lumalabas yung rattle sound na parang may naipit tapos pag nawawala pag below 100 km/h na isa pang conclusion na galing siya sa may engine kasi if i step the gas pedal lalong lumalakas yung sound.... advice naman sa mga technical people diyan ...

salamat in advance...

d kaya sa alternator yung problema??
have u checked the belts??
bka kasi dun galing yung mga rattling sounds na sinasabi mo.

one option ko yan pag mag pa check up na.. any other expert opinion dyan... pero kasi feel ko kasi when i step up the gas to increase the speed lumalakas ang sound and no power na yung engine... yung sound nya sounds like yung electric fan na nilagyan mo ng isang object yung parang sa roleta yung pangpatigil...... ganun yung sound niya...

ipa check up mo agad...

dont wait for other's comments kasi hindi pa naman nila nakikita ang engine mo...you'll feel alot safer if you go to your nearest trusted mechanic.

sa belt yan..

palitan mo na ng bago.. o baka maluwag na.

**marwen** · April 21st, 2003 03:55 PM

yup.. ipapacheck up ko naman.. sa akin lang.. baka kasi hindi ko alam kung ano ang sasabihin ko sa mekaniko at least meron din akong idea from the experts diba...

ang disadvantage ko kasi... wala akong alam masyado sa automotive and im not from manila so hindi ko mapupuntahan yung mga shops na recommended ng tsikot.com.... cebu based kasi ako im working here .. pero davao yung origin ko. Help naman kung me alam kayo mga shops na pwede ko ipa check up dito sa cebu.. surplus car kasi converted from RHD to LHD

If mileage is high or you suspect it's higher than shown on odometer, then check the timing belt, tensioners together with other belts.

Try to ask the mechanic to check ALL your belts (if they haven't been changed, replace mo na kaagad, including the timing belt!).

Try to ask them to examine the steering system, ingat ka dyan sa mga converted, minsan panget ang pagkagawa, lalo na kung palpak ang welding and all, delikado yan at high speeds!

Also, try mo i-rev yung engine mo (to the point where its supposed to be around 100kph) when you are stopped. Then let the mechanic check, kasi kung mat tunog ma-isolate niya kaagad yan.
