Life of 4.5 petrol motor

[altech]

Hi Guys, GU motor is coming up 380,000 km and still going strong. Change oil when needed and get tappets done when needed too.
all great with motor and no oil leaks. is the motor life up for another 380,000 km or I'm I dreaming regards Alex

Why worry, you can buy the engines for a song now :)
I just sold mine with 136000 on the clock for $1000.

Providing you take good care of her, keep the fresh oil in it, i wouldnt be stressing.

I have 300 on mine and she still starts first go everytime regardless of how long she sits

Yes, you're dreaming, but what do you care?!!
Lot can happen during that time and you can end up getting another fourby or swapping the engine for peanuts.
The motor has been serving you well by the sound of it.
Look after it and enjoy it. Don't think too far ahead when it comes to motor vehicles. They are what they are.

Some GQ 4.2s have 750k on them and the 4.5 is basically a bored out 4.2
you should have plenty of Kays left if serviced right

The guy must have been driving it like a nana. ;) :D

It's a good to know 4.5 is basically 4.2 bored out. I thought they totally reinvented the wheel with the 4.5. Apparently not.
Does this mean these engine's are swappable?

Yep. At the end of the day it's something to get you around. I learnt the hard way on my last 4by. Wanted to be like everyone else. Now it's what "I" want/need.
I'm happy with what my gas blower does, even if it's the most unconventional Patrol out there.

The 4.5 is a totally different engine. Alloy head and totally different block. It uses a timing chain, the TD42 uses gears.

They are "swappable" (I've just done mine) inasmuch as the engine mounts are in the same place and they have the same transmission fitting (as does a ZD30).
Exhaust manifold is same bolt pattern as is viscous hub & fan.
No alternator, steering or A/C brackets fit. Coolant inlet/outlet are totally different.

I think he was referring to the TB42 not the TD42 :-)

You're right! Sorry about that, I have TD42 on the brain these days :)

Yeah, I was. But, TB and TD42 are swappable engines, aren't they?
Pretty much a straight swap, as far as mechanics go?!!

The issue with predicting how long an engine will last is that by 400k most components have reached there designed life span. Things like case hardening on camshafts (very thin) could wear through. Valve seats burn and therefore the valve cant cool and burns, piston rings lose their tension on sidewalls etc. All the servicing in years gone by, how good a quality oil was used, all the times it got worked severely in heavy sand dunes, overheated or ran hot, how well it was put together at the factory will determine its life span. And of course how it is driven. Having said all that and if it has had a lovely little life, it could definitely go another 100k, possibly 200k if everything go's perfect and you do drive like Nanna before your arms will be reaching right down into your pockets

My TB42s has over 430k on the clock. Gets driven hard, revved hard and left to sit for weeks. I keep an eye on the oil and coolant but as said above, theres no point over stressing about its longevity. Cross that bridge when you get to it and for now just drive and smile!
