Whilst I had my motor modified at Billcar, I took a few photos to show what goes on and the state of the abysmal affair that Nissan fit.
Please bare in mind, I use top quality oils, I service every 6000miles.
You'll see how my timing chain has stretched, not any major but there's a definite difference in length between my stock chain and the new Billcar Duplex.
When you buy your cheap eBay duplex kit, do you get a re-manufactured vac pump with a newly designed uprated shaft??
I'll guess the answer is no, so fitting all the duplex kit is good, but your still leaving a weak link'
The timing chain cover showing everything in place is a worn cover, not mine...
But the tensioner & guides were my worn parts. Obviously you can't see the sharpness of the gears, but any engineer will tell you, sharp gear teeth are the first signs of wear.
The Billcar quoted price to me included new anti-freeze, oil & filter, all gaskets, duplex timing chain kit, new aux drive belts & the modified exchange vac pump, labour & vat.
A very top quality outfit, superb workmanship and knowledge that nobody can match.
As I had other mods done I can't really & honestly advise any differences to the vehicle JUST on the duplex mod, apart from the obvious satisfaction that I now have an engine that is capable of what Nissan should have ensured as standard.
So after looking at my 40,000 mile chain with 6,000 mile oil changes... Are you getting worried???
Sorry for the **** pictures, all the post was done via my phone.
