Holden LWH Engine Parts

The Holden LWH is a 2.8 litre Duramax four cylinder turbo diesel. The LWH runs double overhead cams, sixteen valves and common rail direct injection. Holden fitted it to the Colorado RG and the Colorado 7 from 2012. Most of this stock is boxed for the LWH and the later LWN revision of the same 2.8. Willys lists 15 parts under the LWH, weighted towards gaskets and seals.

Holden LWH timing belt set

The LWH is belt driven at the camshafts, not chain driven. One NVP timing belt set is listed, boxed for the LWH and LWN 2.8 Colorado.

LWH gasket sets and crank seals

Full and lower gasket sets are both here, the lower one supplied with the rear main seal. Rear main, front crankshaft and camshaft seals are also listed on their own. A rocker cover gasket and a Victor Reinz exhaust manifold gasket round out the sealing stock.

LWH piston, ring and bearing sets

A TIK piston set covers the LWH, and the TP ring set here suits TIK pistons only. ACL main and conrod bearing sets are also listed.

LWH rocker arms and the rest of the shelf

Rocker arms are listed two ways, bare and as a rocker arm and lifter assembly. Work out which one you need before ordering, because a bare arm will not cure a collapsed lifter.
