2006 LAND ROVER FRELANDER 2 ECU

The cyl inder head and st ructural cams haft cover are manufactured to form mat ing parts . The part s are mil led i n a si ngl eoperati on and accurat ely pos it ioned wi th 2 alignment s leeves. The 2 components mus t al ways be ins tall ed t oget her, andnot renewed as s eparate component s . The cyl inder head and cams haft cover are s eal ed to each ot her during manufact urewit h a gas ket and s ili cone bas ed s eal ant, and are s ecured wit h 27 bolt s . An oil s eal i nst all ed at the front of t he cyl inderhead provides s eal ing of t he exhaus t camshaft hous ing. The open port s at the rear of the cyli nder head are sealed wit ht he vacuum pump and hi gh-pres s ure fuel pump s eal ing rings .
Two ali gnment sl eeves correct ly l ocat e t he cyl inder head and gas ket to t he cylinder block. The cyli nder head is secured t ot he cyl inder bl ock wit h 10 deep-s eat ed bolt s .
• NOTE: The cyl inder head bol ts are not acces si ble wit h the st ruct ural cams haft cover i nst all ed.
• NOTE: The cyl inder head is not t o be reworked.
The cyl inder head is manufact ured from al uminum alloy, havi ng valve s eats and guides made of s i nt ered st eel. Thecyl inder head is precis ely machi ned and mil led t o i ncorporate t he 4 combus ti on chambers, cams haft l ower beari nghous i ngs , oil drill ings and cool ant gal leri es, and t he air i ntake, val ve ti ming and fuel sys t em component bores andhous i ngs .
The desi gn of the cyli nder head maximizes air flow and s wi rl i n the combus ti on chambers. The 2 int ake val ve seat s aremachined wit h rais ed profil es that act to promote swi rl of t he int ake ai r fl ow. Combined wit h t he acti on of the i ntakemanifold heli cal port , t he s wirl effect of the 2 int ake port profi les al lows t he air and i nject ed fuel t o complet el y mi x, andreach t he outer edge of the combus ti on chamber.
The s truct ural camshaft cover is manufact ured from alumi num all oy, and i s machined on t he upper s urface wit h t hecamshaft upper bearing hous ings . The cover is al so formed wi th 4 int ake ai r fi ll ing t racts , fuel i nject or bores and ori fi cesfor t he cyl inder head cover PCV components .
