Premium valve regrind gasket (VRS) and head bolts combo set is designed to meet and exceed OEM specifications. Each item in this set has been checked and evaluated, so you can be assured of quality fitment every time.

Head bolts play a vital role in the sealing of the combustion chamber, oil/coolant channels and ambient air. Therefore, we recommend our cylinder head bolt set for the task. Having met and exceeded OEM specifications, these quality bolts are suited for standard and mildly modified applications. These are a torque-to-yield (TTY) type bolt which means they can be tightened past their elastic limit, guaranteeing high and uniform clamping forces. No-retorquing is necessary after correct installation procedures have been followed.

This valve regrind gasket set and head bolts combo pack suits Nissan vehicles fitted with the YD25DDTi Turbo Diesel I4 engine.

Vehicle Fitment Guide

Notes:

• This set only suits YD25 engines with a 8 inlet port cylinder head.
• When torquing up bolts, an accurate torque wrench or angle gauge will be required to achieve correct clamping forces.
• Please follow the torque specifications as recommended by the service manual.
• TTY bolts are only to be utilized once due to permanent elongation and safety concerns.
