[GT6 Mk3 only runs well with VERY advanced timing. Any ideas why?]

as yours is still assembled you need to use the equal tappet gap to get the cam lobes at their   TDC

so feelers is all you need with a piston stop to set the piston at TDC  you must not rely on using the timing cover marks 

and hoping the crank doesnt turn while you are fiddling about .

you can make a piston stop by wrecking an old spark plug by remove the electrode and adding a bolt

[Oil change: can you identify this ?]

thats nowt to do with the spin on filter   its either spurious or packing for some obscure reason 

i would put it in the might be useful one day but not for oil changes 

Pete

[GT6 Mk3 only runs well with VERY advanced timing. Any ideas why?]

you need a protractor ?dial  (like on the crank )  on the cam   set the DTI on inlet lobe mark the degrees 

for say 0.025 on the up and down from highest   mark the centre of the two .

do same on exhaust lobe   mark the centre of the two readings 

if on compression stroke  turn cam exactly 180 degrees (half a turn)  ft the chain with the best aligning holes 

as compression stroke uses the back of the lobe  you need to turn the crank one turn so the two lobes are uppermost 

just check both lobes give the same lift on a DTI (or feelers under the rocker )  at TDC

well something like that      easy to do not easy to write it  Ha

eed to get the cam lobes in balance and exactly mid point highest point   

best use a dial indicator to get the centre of the cam ramp

[Is it worth fitting one of those glass inline fuel filters?]

and the more you play with the fuel hose the more rubber slivers breed .

I agree with Johny   dead end pressures are not controllable get the pump under control by spacing from the block and simplify the filtering 

they lasted 50 years before paranoia filtering got into the aftermarket 

unfortunate but  most problems of debris are the now  aged fuel tanks and fake rubber hose let alone whats been pumped in via the filler over the years

[Radiator cap touching bonnet]

who welded the drop links  ?????   nuts 

these (should)  do need to swivel so when adjusting the turnbuckle on the tie rods the bonnet moves fore /aft to set the gap to the screen panel .........   thats not possible if the links are welded

you can see the links on here item  36

yes wheatabix not blow lamp  

we have enough problems with the crank pulley damper ring bonding breaking loose without cooking it 

then you are in the doo doos as they are not overly available these days 

locking the ring gear is a good way then all energy is on the bolt not winding the transmission up

transmission just winds up....

thats exactly why care in overtorque doesnt destroy the clutch damper springs the engine max torque is around /upto 115 lbft  easy to bust that with a scaffold pole or similar overloading 

pete

[Radiator cap touching bonnet]

the cone heights look ok  there is an adjustable drop link hides under the overrider 

that would raise the os and even up the taper better and you gain a few mm across the front of the bonnet 

Pete

[Radiator cap touching bonnet]

the O/S door gap looks like that side need to be raised to get the taper door gap to a parallel gap 

are there pads on the rad mount brkts you could remove ??

[GT6 Mk3 only runs well with VERY advanced timing. Any ideas why?]

if you think about where the thread section is then any squirt on stuff wont get anywhere near it 

it needs a sharp shock ,so a decent ring spanner and  a clout  with a club hammer 

but a 1/2 drive impact  battery gun is the best solution so put one on your wish list along with a set of impact sockets 

preferably in imperial sizes

[Outriggers & rear extensions]

pic of the  approach to repair the floor/A post base and the two front body mounts  

i believe Chic Doig made a repair section for this job   it was a nightmare of patch and head scratching  

if we did it again we would have known more ....always clever after the event 

Pete

 

[Outriggers & rear extensions]

my first  Herald a 59  948  we had in 67   had no floor and the two front body mounts were just holes in the floor 

so at 8 years old it was a complete rust bucket in 1967

,frequent gasket failures  ....do make sure you have the fixed strap down pipe to gearbox  as this steadies  the pipe 

Pete

[Zero compression on cylinder 4]

one very normal place is the short hose  off the  top of the tank  hidden in the boot on all H &V   this is often the cause of loose /degraded hose that sucks air and stops the pump suction  and could well be the common with both pump failures 

Pete

[Revs drop pressing accelerator at idle. Herald 1200 Solex B30PSE1]

there are changes to needle valves on early and late B30pse1 carbs probably where the changes in size occurs 

its not overly important 

canley show them all throughout the 1200 range of carb  changes

cant get the Burlen site to work since its all changed (might be me )

they do wear and can jam up with little to see why 

Pete

[Zero compression on cylinder 4]

remember any fuel hose fitting has the possibility of breeding the dreaded rubber slivers  get sheared off the rubber hose when inserting the metal pipework these float about and jam/block the back of the float needle valve 

its very common problem , less so with gates barricade hose which seems a much tougher compound 

Pete

[Herald 1200 rocker cover breather confusion]

yes swap it around the only restriction is if  the filler may be too close to the bonnet

[Zero compression on cylinder 4]

i would start by reading up about setting the shift cable on Rovers it could be well out of adjustment .

kick down .....wont have any real effect on the basic selector settings 

normally there is a small ferule crimped on the carb end of the kick down cable and at idle this should just touch 

against the cables  abutment 

oil level   yes  basic needs to be ok ( is there a cold fill and hot fill level on the dipstick )  ????
