Re: Rough Motor


What oil are you using Bob ?

Our QR25DE engines use a hydraulically assisted timing chain tensioner and when the engine gets older the 5W30 oil is too thin to create enough pressure in the tensioner to keep the timing chain tight enough and so it can rattle a bit.

I changed to 10W40 grade once mine got over 120.000km and both the slight oil consumption and chain rattle went away.
Give that a try as it is easy to do.

Re: Rough Motor


Thanks for the thought kev i recently did a trip to orange & noticed the oil was low so added 1 litre of 20/50 caltex normal oil but that was only 2 weeks ago i will keep an eye on it.
