Timing Chain tensioner QR25DE


Hi can anyone enlighten me as to whether the hydraulic tensioner should have a O-Ring between it and the mating surface on the head?

Re: Timing Chain tensioner QR25DE


I have a genuine chain tensioner in my hand and there is no indent on it for an O-ring. There is also no replecement O-ring in the box with the tensioner.
The electronic service manual shows an O-ring but it looks like it is in a different place from where the tensioner bolts onto the head.

Gotta agree with you Kev.
After re-building Datsun/Nissan engines for the past 40 years, I've never seen an 'O' ring located in the tensioner.
