what your advice on how to fix this problem?:

- anytime the engine is cold, i hear a loud rattling noise for abt 1-3 seconds from the head of the engine. after that car works fine..

info i got is that its the timing chain belt thats the culprit. its not getting enough oil at startup to lubricate when in motion hence the rattling metal on metal noise.

some people tell me to change the tensioner, others say change the chain itself cuz it stretch, others say change the cam gear, others say change the chain guides,

i was thinking switching to a better oil, if dats it then wat is the best brand and type of oil to stop dat?

thanks with blessing for the response.

May just be a sign of sludging which these engines have been showing quite frequently locally.
If this is the case,I would bet oil viscosity has been 'too heavy' coupled with protacted use of low end oil filters.
If this is not dealt with the need to repair engine could be in the very near future.
Get a repairer who understands these engines to determine problem quickly.

The issues with this vehicle would be best established by of a proper assessment by a experienced mechanic in light of the new infor.
Is this the same vehicle in your other thread with tranny issues?
If this is the case you have some real 'wear and tear' consequences.
I am unable to understand a engine rebuild 'using back the same parts'.

The timing chain will usually make a constant ridiculous racket when its bad. I feel it may be the vvt timing gear. If it was the bottom end it would usually be because u have a worn bearing or a spun bearing and that would be like a jack hammer all the time. When u start take a listen by the left of the head by the bulge in the head cover and see if its around there. hope that helps.

Good Afternoon, let not your heart be troubled. Simply change the engine oil you are using - I am almost sure you are using a 20/50w oil ? I had this exact same issue and changed to 10/30W oil which is the designed spec oil for the engine...
