1-High-pres sure common fuel rail2-Bolt (2 off)
The common fuel rail is manufact ured from forged s teel and is s ecured wi th 2 bolt s to the cyli nder head, above t he li ne oft he exhaus t cams haft . The fuel rai l st ores press uri zed fuel from t he high-pres sure fuel pump and deli vers t he fuel t o thefuel inject ors .
The fuel rai l pres sure is regulat ed by a Pres s ure Cont rol Valve (PCV) l ocat ed at the fuel pump end of the fuel rail , undert he cont rol of the ECM. A fuel pres sure s ensor i ns t alled in t he oppos i te end of t he fuel rai l provides t he act ual fuelpres s ure s ignal to the ECM. For addi ti onal i nformat ion, refer to:

Fuel Injectors

The lubricat ion sys tem is a wet s ump, pres sure fed type. The oil lubri cat es t he engine s lidi ng s urfaces , di s si pat es heat,absorbs fuel combus t ion resi due and seal s off t he gap between t he cyl inder and pis ton.
The engi ne is lubri cat ed by a force-fed oil circul at ion sys tem compri si ng a full-fl ow oi l fil ter and cooler ass embly. The oilfi lt er and cooler form an int egral ass embly mount ed on t he LH s i de of the cyli nder block, in clos e proxi mit y t o t he oilpump. Engi ne oil is cooled by the engine cooli ng s ys t em, and eliminates t he requi rement for an addit ional remot elymounted engine oi l cooler.

Dri ll ings and galleries connect ed to the mai n oilgallery deli ver pres s uri zed oi l to the cyli nder block and cyl inder head reciprocal component bearings. A dri lli ng above No. 3main bearing cap direct s pres s uri zed oi l to a port at t he rear RH si de of the cyli nder block. The port provides pres s uri zedoil t hrough a banjo connect ion and pi pe to the t urbocharger bearings.
All t he engi ne moving parts are l ubricated by press ure or spl as h oi l. Pres s uri zed oil is al so provided for operat ion of t hehydraulic las h adjus ters and ti ming chain tens ioner.
Oil i s ret urned t o t he oil pan under gravi ty. Large drain holes cas t in the cyli nder head and cyl inder bl ock al low a quickret urn of t he oil .
The lubricat ion sys tem is replenis hed t hrough the oi l fi ll er cap, locat ed on t he engine acous t ic cover. An oil l evel gage islocated on the LH si de of the oi l pan. Two marks at t he end of the gage i ndi cat e t he mini mum and maxi mum oi l levels .The difference between the minimum and maximum marks is approximat ely 1.5 l it ers (1.58 US quarts ) of oil .
