Sons new Mav is making a fairly audible whine from front of engine.
Fairly sure its chain/tensioner but may need to replace all of this as a precaution $240 timing chain kit+ oil etc
Any tips, things to look out for doing this job on a TB42 ?.
Yep, if the timing cover is std/unmodified (you will see its been welded in places) take it to someone who knows where & how to reenforce it with weld. They have common problem with pinholes in the water jacket aria & it would be hard luck to do all that work just to find yourself ripping it all back down to do a repair that could have been covered while it was all apart in the first place.
The gen nissan chains are made to length, so you will need to remove sprockets to get chains off.
Replacement chains have joiner, so easy putting on/off.
The oil pump tensioner is not self adjusting.
This is a problem and needs adjustment.
If rubber is worn then it's worth replacing.
The $235.00 Kit as pic contains,
3 x guides.
1 x tensioner.
2 x chains.
1 x front cover crank oil seal.
Recon for 150 thou+ wear "n" tear, the kit is excellent idea.
Every engine is different here, wife car is 250thou and needed manual tensioner adjustment, but wish I priced kit and would have done this instead for the peace of mind anyway.
Sons ,oil chain tension had been wanting for some time.
It had folded teeth over a bit on pump sprocket.
Lucky fair price, available genuine only, $65.
If you know your way around this sort of job, then 1 solid weekend will see this job sorted.
You will need a good selection of tools .
Removing the sump is part of the job.
Oil and new coolant.
belts, thermostat , idler pulley maybe etc.
Its 1 of those job you can find yourself doing more as you start to look.
Consult a manual first, Any ? post me.
I'll try to help out, "if I can find time".
Cheers

Was lucky, the cover was in good nick corrosion wise.
Good clean, new crank seal installed and ready for another spin around the block.
