Diesel mechanic recommendations.

G'day everyone. I have an 08 D22 YD25 Navara. 193000kms. It's never had the timing chain done. I'm hearing a pretty loud rattle at times coming from the front of the engine. I think it's long over due now. Anyone know a good workshop to do this job. Moss Street area Logan would be ideal.
I have been told Steve Jordan from Nissan Auto Parts in Herbert Street is the go.

The timing chain is a reasonably big job. Get the tensioners checked (replaced is better) and make sure the oil galleys are cleaned. The main cause of timing chain wear is an auto tensioner that isn't pulling enough because it's been gummed up.

I don't know anyone who can service diesels in the Logan area..

Very likely that's timing chain noise.
From the factory, the lower chain is single width and has a tendency to break from 150,000 on.
YD25.com.au sell very good upgrade kits to double width and will also fit.
Sort it out asap before the chain breaks or the pistons will crash the valves.

Hi everyone,
Just something to consider here regarding a loud rattle coming from the front of the motor at times.
I am currently doing some work on a V9X that had the same loud rattle at times.
By chance I found that the harmonic balancer was worn and when I hit the pulley with my hand it makes the same noise I was hearing. This by itself was not of much consequence, by my reasoning anyway, except that I looked at all the idlers and other bearings and lo and behold found that the AC compressor had a stuffed bearing. Because I was only hearing the noise at idle, I believe it was that notchy bearing jolting the belt and "clacking" the harmonic balancer.
Worth checking out before delving into timing chains.
