CYLINDER BLOCK COMPONENTS

11-VGT oil return port
12-VGT oil s uppl y port
The cyl inder block is manufact ured from cas t -i ron and feat ures double layer wal ls t hat provide high st rengt h and ri gidit y.An air cus hion i s formed between t he l ayers and als o acts t o reduce t he NVH l evel s produced by the engine. The blockfeat ures 5 bol ted mai n beari ng journals that als o provi de high s t rength and rigi dit y to the l ower end of t he engine.
The cyl inders are direct ly bored int o t he cyl inder bl ock and do not require cyl inder liners. Two gui de s leeves are l ocated int he cyl inder bl ock, and provided t o correct ly al ign t he cyl inder head and gas ket to the cyli nder block.
A hole formed in the LH rear of the cyli nder bl ock below the st art er motor, provides the locat ion for an engine t imi ngs pecial t ool . W hen i nserted, the special tool locates i n a corres ponding hol e in the flywheel to temporaril y hol d t hecrankshaft wit h No. 1 pis t on at the Top Dead Cent er (TDC) posi ti on.
The oil filt er and cool er hous ing, and main oi l gal lery are locat ed on t he LH s ide of t he cylinder block. The mai n oil gall eryis a longit udinal dril li ng that runs t he l engt h of the cyli nder bl ock, and s uppl ies pres s urized oi l to al l the engine movi ngcomponents . Pres s uri zed oi l is di verted from t he main oi l gal lery to s upply the main and bi g-end bearings via diagonal oildri ll ings in the cyli nder block, and in t he crankshaft journals . The mai n oil gall ery i s s eal ed at each end wit h a s crewedplug.
A cros s dril ling above No. 2 mai n beari ng direct s pres surized oil from the main oi l gal lery to a port at t he Right-Hand (RH)s ide of t he cyl inder bl ock. The port s upplies press urized oil via a banjo t ype connect ion to t he VGT beari ngs. Ret urn oi lfrom the VGT is direct ed via a pipe and a connect ion at the RH si de of the bl ock, i nt o t he oil pan. A vert ical dril li ng at theLH front of the cyli nder bl ock s upplies press uri zed oil from the mai n oil gall ery, up t o a corresponding oi l gal lery in t hecyl inder head.
Engi ne cool ing i s achi eved wit h int er-cyl inder coolant chambers and expans ion chamber dril li ngs , formed i n t he cyl inderblock cool ant jacket . The coolant chambers direct coolant t hrough openings i n t he block upper s urface to the cyli nder head.Core pl ugs seal t he ext eri or openings formed i n t he cyl inder block coolant jacket.

The 4 oi l s pray jet s are i nst all ed in the LH si de of cyl inder bl ock bel ow each cyl inder. The jet body i s s eat ed direct ly i ntot he main oi l gal lery. Pres s uri zed oi l is s prayed beneat h each pis t on to lubri cat e t he cyl inder wall and gudgeon pin, and t ocool t he pis t on crown. As the spray cont act s t he undersi de of the pi st on, the oi l col lect s and flows around 2 formed cool ingchannels t o cool the pi st on crown.

A CKP sens or is i ns t alled at the front of the engi ne, and i s s ecured to the cyli nder block wi th a locati ng dowel and s crew.The posi ti on of the sens or is not adjus table. The s ensor head is pos i ti oned clos e t o a corres ponding target ring l ocat edbehi nd t he cranks haft drive pull ey. The t arget ri ng is keyed on t o t he crankshaft.
The s ens or is a variabl e rel uct ance s ens or t hat provides an i nput of engi ne crankshaft speed, and No. 1 pis ton pos it ion tot he ECM. The informati on is us ed by t he ECM t o det ermi ne the quanti ty of fuel to be inject ed, s t art of fuel delivery, andquant it y of exhaus t gas to be recircul ated.For addit ional informat ion, refer t o: Electroni c Engi ne Controls (303-14 Electronic Engine Controls - 2.2L Durat orq - Td4,Des cript ion and Operat ion).

3-Coolant pump
The engi ne cool ant pump is a cent ri fugal type, and is direct ly driven by t he t oot hed cams haft bel t. A s eal ing gas ket and 7bolt s s ecure the pump to the front RH si de of the cyli nder bl ock.For addit ional informat ion, refer t o: Engi ne Cooling (303-03B Engine Cooli ng - TD4 2.2L Dies el , Descripti on and Operat ion).
Oil Filter and Cooler Assembly
A combined engine oi l cooler and fil ter as sembl y is mount ed on t he LH s ide of t he engine block, in-line wit h No. 3 cylinder.The fi lt er hous ing contai ns a dis pos abl e paper fil ter element , and an oil pres s ure swi tch.

2-Counter-balance s haft dri ve gear
A formed hel ical drive gear on t he cranks haft provi des the drive t o t he count er-bal ance s haft as s embly. The cranks haftdri ve gear contains twi ce the number of teet h as each of the balance s haft gears , and therefore drives t he 2 balances hafts at twi ce cranks haft s peed. The cranks haft gear drives t he cont ra-rot at ing balance s haft i n t he oppos it e direct ion tot he cranks haft . The remai ni ng balance s haft is driven by t he cont ra-rot ati ng bal ance s haft i n t he direct ion of t hecrankshaft .
A s him plat e i s located bet ween each s ide of t he balance s haft hous i ng and the cyli nder bl ock s kirt. The s hims areavai lable in varyi ng thi ckness and are us ed t o provide the correct backl ash bet ween t he cranks haft drive gear, and t hecont ra-rot ati ng shaft gear. The backlas h between each balance s haft gear may be checked, but is not adjus t abl e.
The rot ati ng balance shafts creat e an opposi ng force to counter t he imbal ance forces produced by the engines reci procat ingcomponents . The i mbalance is creat ed in a 4 cyli nder engine as pairs of pis tons move in opposi te direct ions during theengi ne s trokes . To count er the oppos ing forces of the paired pis t ons , t he balance shaft weights must be at Bot tom DeadCenter (BDC) when a pis ton pai r is at TDC.
Lubricati on of the counter-balance s haft as sembl y is by spl as h oi l.
