hmmm, 3.2 next Mark? ::)

And by the way, is it likely all 2.6 and 3.2s will be effected?


Geff confirmed that both the 2.6 and 3.2 were affected for a short production run

Will Geff have ideas of what range of engine numbers they fell in??

He didn't know but, said it was only early units around 2001

No pics tonight as didn't get much done.

Cleaned a few items (oil cooler plate, transfer pipe etc), servcie the followers and primed with a bit of fresg oil.

Need to do the alternator idealy soon and get the engine bay and block cleaned ready to start putting some bits back.

just a rather late thought, but any reason why 3.2s suffer a bit with lazy lifters when oil changes are left a bit too long and the 2.6 doesnt? or at least i dont see any 2.6 owners complaining about it...

No difference between the two on that one....both could suffer the same.

I have found noisey lfiters during running due to one of two things

1) Very poor servicing resulting in oil pump wear and low pressure

2) An engine that has been flushed, often the oil pickup strainer is a bit clogged.

Again, not much done today as I have been fitting a water softener this weekend.

Managed to get it on the road and give the engine bay a good wash down.

Aircon compressor was covered with a bag to protect the bearings, alternator was removed as its bearings are already noisey!

Filthy!





Also, managed to start stripping the alternator down.

Off with the pulley (break me tight!) nut



Removal of the 4 bearing retaining plate screws (I use a cordless drill to get plenty of sudden torque behind these to shift them as they are loctited in!)



Removal of the rear cover (this is the later type, the early versions are much easier!)



Removing the 4 main body securing screws



One of them is a little hard to get at so out with the cordless drill again!



And got, the oil cooler and oil cooler pipes re-fitted and oil filter and housing re-fitted.

Looking a bit cleaner now





Plus a few more random pics

Knock sensor number one and the starter motor



Oil level sensor and the oil pump (later type)



Knock sensor number 2



Oil filter housing location, crank sensor and the oil cooler pipe holes



Side shot of the steering box with the cabin coolant pipes poking through the fire wall



Further shot of the steering box, you can see the solenoid which varies the assistance with speed just to the bottom right of the pic



Aux coolant pump bracket....this is where the cruise box is fitted on cars wothout drive by wire throttle

I had to have some 'fit it back on therapy' today as all I have done so far is take stuff off this lump!

Should add, whilst the pressure washer was out, I cleaned all the cable trays etc so should be nice and clean

The alternator is re-furbed and re-fitted now.

The other head is stripped and had its first clean, ported and ready for its final clean before re-build. The valves are cleaned and the springs, bases, caps, collets and T-vents are also cleaned.

Once its had its final clean and check, assembly can begin.

Interestingly this head has been in the wars.....

No 4 combustion chamber:



No 6 combustion chamber:



You can see damage due to what I would guess is where the engine has gobbled some plug electrodes, perhaps Mick can confirm if this lump has had an appetite for ceramic and metal at some point in its life!

Relaity is thats its nothing more than minor grazing so wont cause any issues.

And how the compression was lost!



Its now clear that the very minor dish in the piston crown is not the cause of the compression drop....they simply fitted shallower pistons (the 3.0 and 2.5 ones come flush to the top of the bore!)

Crank seal was changed with the help of Matchless and his huge torque wrench

The final head got its final clean last night and had the valves lapped in plus stem seals fitted.

So, it needs springs, collets etc +manifold and heat shields fitting plus the followers sorting and its ready to fit.

The its......'on with its head (s)!!!'

Also got an engine under tray off Mr LooKnee (thanks) to save the bottom end getting so filthy in the future plus it will aid cooling to.
