*Ultimate K Series Head Gasket Fix - N Series Gasket, High Tension Head Bolts and Revised Oil Rail. Equiv to ZUA000530

In stock and ready to ship. 

It's finally here - when SAIC revised the K Series for fitting to the MG7, they changed the construction of the Head Gasket, used higher-tensile Head Bolts and fitted a re-enforced Lower Oil Rail. You can now fit these parts to your K Series-engined MG Rover vehicle.

The revised engine used in the MG7 also had minor engine block and head changes, however the majority of the changes were brought about by the items included in this kit. 

This kit is currently fitted to many high performance K Series powered vehicles - including a Judd-engined MG ZR and several Lotus Elise / Caterham 7 models. 
It's also the current solution of choice for those fitting a 1.8T engine into the MG ZR / ZS - allowing power levels in excess of 200BHP without having to worry about failure.

Revisions to the items included:

  • Head Gasket: new 6 layer construction with revised fire-rings, a sealing surface coating and other minor changes. 
  • Head Bolts: Tensile rating changed from 9.8 to 10.9, meaning more pressure applied to the sealing surfaces of the Head Gasket. Observe tightening sequence below. 
  • Lower Oil Rail: Additional webbing and thicker casting adds additional strength, meaning clamping load is maintained. 

The kit is supplied in one of 3 forms:

  • Basic Kit - includes the Head Gasket, Head Bolts and Lower Oil Rail only. 
  • Comprehensive Kit - Includes the contents of the Basic Kit, and camshaft seals, inlet / exhaust manifold gaskets and cam cover gasket. 
  • Ultimate Kit - Includes the contents of the Comprehensive Kit, and a cambelt kit with new all-metal tensioner and waterpump assembly. Also includes a new thermostat with a full seal kit (thermostat outer seal and housing O rings) and 16x valve stem seals. The VVC option of this kit also includes the Rear Timing Belt LHN100400.

This kit fits all K Series applications - 1.1, 1.4, 1.6 and 1.8. Use the drop-down menu to select if you have VVC or not (1.8 only).
