After watching those video's What a nightmare!
It's almost done. Just some last minute gaskets to fix and we can pick it up...... What a journey! Can't wait to get him home though.

This causes the crank to run pretty much dry until oil pressure builds up, increasing the friction on the bearings, which eventually leads to bearing failure. I have noticed that mine has this rattle for a couple of seconds and im wonering what could be done to minimise this, without have the oil pump replced. One thing that crossed my mind, was to turn over the engine for a few seconds, without my foot on the brake, so it wont start, but to assist in building oil pressure, at a lower crank speed. I know this isnt a fix, but am wondering if this could help minimise the time, as witch the crank in running dry at a greater speed. All comments greatly accepted, if this is a viable option for the short term.
cheers

This product might help (if it does what it says) by leaving a film of lubricant on the bearings.Quote:

Well, brought him home yesterday arvo. All going well with the new heartbeat, I forgot how smooth and quiet these vehicles are [bigsmile1]. Just some software upgrades for the gearbox to go and back on track with the mods for a future trip. Question for all, what's the go with the cheap ass snorkels? Are the safari ones worth the (considerably more) extra coin?
Cheers

Look at the airflow snorkel, less than half the price of the safari and made in Melbourne.Quote:

On a side note a conversation with Sydney rebuilder say ALL 3.0lt version can suffer this fate and Says it’s due to incorrect tolerance from the factory on the original crank ultimately allowing the shells to spin. The rebuilds he sells for 12k exchange apparently rectify this. But the crankshaft shells are still not keyed so one does wonder.Quote:

That’s good news. So what path did you go in the end? I saw one of your previous posts mentioned a motor from a donor vehicle. Thanks.Quote:

This noise occurs because the oil is sitting in the sump (where it should be, and not on your garage floor) to ensure the crank and all big ends get enough oil. Plus the oil pump needs enough head to ensure oil is sprayed where its supposed to go. Theres nothing to do or worry about with the timing chain rattle. It will always happen and you cant fix it with a new oil pump. If it goes on longer than a second or two, then your timing chain guides and/or timing chain is stretched. Keep your oil levels correct, change oil every 10,000km and use only the specified grade and oil type, oem filters and you've got a decent chance of not having a catastrophic failure.Quote:
