Having thought about the AWD conversion I'm going to put it on hold. While its likely to be a great conversion the cost is a bit prohibitive, taking into account the amount of fabrication required to the sump, oil pickup, transmission R & R plus other associated costs. Maybe reconsider this at a later stage.
Meanwhile I've ordered bush overhaul kit for the front and rear suspension for a freshen up. Also, since I've had the vehicle the diff has a whine (much like our Premier, Mark McGowan) which has become more noticeable since the diff bushes and control arms have been upgraded to Nolathane & Superpro parts. I've ordered a 3.07 ratio for the M86 diff, somewhere between the 2.73 in the sedan and the 3.23 it currently runs. 3.23 is renowned for diff whine. The 3.07 will give it a little more legs in gear.
New wheels are on the way, got Simmons 19X9 FRC NCT's. Will try 275/45/19's which should fit.
Did an oil change yesterday as I noticed the oil I used last time was as black as bitumen after only 4000kms. Used Valvoline 15W-40 engine armour. Never again, totally junk oil. Switched back to Penrite 15W-40 semi synthetic. No point running fully synthetic IMO as I'll be changing the oil every 5,000kms.
At some time I'll get the timing chain and tensioner plus guides replaced with the Atomic gear. While the engine was rebuilt with new genuine chain, tensioner and guide I think it's peace of mind to replace it after nearly 20k of engine service. The chain does rattle sometime during startup, good enough sign to do the upgrade.
