That cover gets more than warm, especially in the spark plug wells, will be interesting to see how the paint last. Looks great now, clearly labour of love :)

Oh yes indeed, clearly a labour of love alright ... It's knowing when to stop, sometimes. I recall the story about the chap with a cabin cruiser and because of a blown bulb in the "saloon" ended up rewiring, re-decking and almost re-building the complete craft....... :shock:

so , today , i sat down with some feeler gauges, some paper and a pen ( Jaguar pen at that ;) ), i had previously noted all the shim sizes under the lifter buckets under the cam shafts , the shim size was still readable on the shim surface , this was denoted as a '30 or a '26 etc, for all 24 valves , my original shims ranged from #27 to #38 across the 24 valves

then with the feeler gauges i measured the gap between the back lobe and the follower top for each valve, this should be between 0.012" to 0.014" of an inch for inlet and exhaust , ( 12 to 14 thou )

noting each reading under the original shim size for each valve , as can be expected, with some wear and also the lapping of the valves, not many were within tolerance, but most were very close , some 0.0015" and a little more on some (measured at 0.0155" for example + 1.5 thou over max tollerance of 14 thou )

still with me ??

so , now with the original shim size and the new reading of gap , and some calculations i could work out how much bigger a new shim would need to be to close the gap to within tolerance ( 12 to 14 thou ) X24 , lol

so , looking at the parts on Jaguar Heritage, i could work out which new shim i needed , but hold on , not quite that simple, for example a #29 shim is measured at 0.0985" , i need a shim 1.5 thou thicker , so 0.1000" is needed, so looking through the shim table to find the new size, it turns out i now need a #33 reference size shim ,


fun isn't it , lol

so , with some swapping undersize for over size and making a list, i needed x7 new shims of the calculated size , and they should be in tomorrow , cost £4.02 each including VAT , so im happy with that to be honest ,

wish me luck

btw, gap tolerance is between 12 and 14 thou , however it is recommended to go towards the 14 thou side as a little noise is much more preferable to tight tolerances once the engine is at running temperature causing potential galling of metal surfaces....

in-between my day shift and a night shift tonight , i decided to do what i could,


so first thing this morning, i moved all the shims around and added the new ones , and then bolted down the cam brackets after applying some super slippy/sticky engine build lube , and then tightened the cam covers to 26NM , that went very well ,

then i decided i was up for putting the head back on the block , so gave it a good wipe down , checked TDC , placed the new head gasket on and with the aid of my grown up son we placed the new head onto the block , it sat down very nice first time, so happy days,

then i got the x14 new head bolts and dropped them in place, and gave a quck spin up by hand so they sat against the head , then using the correct tightening sequence i torqued each bolt to 60NM , basically you start in the middle and work outwards doing opposite bolts as you go , when each bolt had been tightened i left it for half an hour to ' relax ' , in the mean time i placed a white mark to each bolt had looking towards the front of the car , then used a long breaker bar and a deep 17mm socket and using the same tightening pattern as above i put a 90 degree turn into each bolt, this is easy to do with the white mark , as the start facing the front, and are at 90 when facing the right wing , thats the head fixed down ,

i then offered up the exhaust manifolds to the mostly new studs , and fixed them down with new gaskets and spring washers, and then placed the refinished rocker cover on to stop any debris falling into the cam head ,

next is to fit the cam chains and upper sprockets to get the timing correct, and then the chain tensioner and the distributor,

but that wont be until im off nights now

let the buttoning up commence

firstly , get the upper cam timing chains and pockets set , with the engine at TDC and the inlet and exhaust cams confirmed with the setting tool you pull up the cam chain up onto the inlet sprocket , pull it tight and place in the centre facing plate with x4 bolt holes, this will only go in one way , ensure new locking tabs are placed in , then place the chain and exhaust sprocket over the exhaust cam , and then insert the chain tensioner to take up any slack, when satisfied place in the inner locking plate and x4 bolts as before, check TDC on everything again , and tighten as required and pull over locking tabs

then the upper chain guide needs fitting ,

then the distributor can be placed in using the position marked before removal, and the contact pointing towards the 5 o'clock position towards the cutout tab ,

i then got my 32mm ratchet and after lining up the cams etc, i turned the engine over by hand on the lower crank bolt, checked the TDC at one revolution , and did another revolution , and again checked TDC , it was all in the right place, so i placed on the cam cover seals and tightened down the cam cover
i also added the dizzy cap and leads for that ' finished look , lol'

thanks , its been quite hard and very intricate and technical at times, but hopefully worth the effort , as i think i want to use her as my daily driver....... we shall see


so , as of this evening, everything is now put back together, the intake manifold got new gaskets and bolted up quite easily , this was after connecting up the interior heater matrix pipe valve at the back of the head which is under the intake side, my late car has a pipe and olive with back-nut fitting, unlike earlier cart with the longer pipe to the valve ,

then i fitted the thermostat block to the head, i searched high and low for a gasket but couldn't seem to find one,,,,,, ( when removed i didn't see one either ) and it seems that on the late AJ6 the mating surfaces just get some gasket sealant and are face to face fitting, so thats what i did, connecting up the remaining cooling systems pipework and bits and bobs ,

fitted a new Genuine Jaguar oil filter ,

then i connected up the TB induction pipework and airbox , a few final fittings to button it up

tomorrow ( if it doesn't rain ) i will drain the rest of the engine oil, fill with new, and fill with some ready mixed OAT coolant specially mixed for aluminium engines ,

crank it over with the coil disconnected to get oil pressure etc, and then see if it makes any nasty noises, lol

thanks for staying with me on this, and have a go yourself,,,,how hard can it be :shock: :shock: :lol:
