What is a typical engine life???

As the title suggested, what would be the typical engine life of a ford falcon? This topic has always interested me since I got my first car off the old man (1990 XF ute, gave it to me with 410000km, now up to 495xxx). With the great advancements in electroics and precision engineering I would have thought the engine life would have dramatically increased.

I was also told that a V8 engine should last many more Km's than a 6 (either V6 or i6), due to the 8 cylinders in a V8 firing less times per cylinder that a 6. For example, say we a cruising at 2000rpm, this equals 33.33 revs per sec, or 5.55revs per cyclinder per sec for a 6. Now in a V8 at the same revs we would be revolving at 4.167 revs per cyclinder per sec. I know that we wont always be at 2000rpm, but in general, at any rpm, a 8 cyclinder engine will be revolving less times per cyclinder than a 6, hence a increase of engine life. So considering this, do you think a 8c engine has a greater life than a 6???

What are you opinions?

How long is a piece of string? It all really depends on how the engine has been treated, has it been serviced regularly, did they use high quality oil ect..

I have heard of 6 cyl 4.1 motors doing up to 750,000 before being rebuilt . These were taxi motors and but most will do 500,000 before needing rebuilds if looked after ! I think most motors average around 3 to 4 hundred thousand though !

I usually freshen my clevo's about every 40 or 50 thousand. but they get driven hard , and rack a few burn outs in that time as well!

no.

it all depends on how the engine has been treated and serviced.

My EF I6 is up to 328,000 and is still on the original head gasket and has never had a rebuild where as my dads F100 with 351 clevo is up about 360,000 and has been rebulit once already and is now due for another

590,000 kilometres in a XE carby fed falcon:oil change every 5000 kilometres and filter every 10,000.

It all depends on how well the engine is serviced but a general rule is that a Falcon engine will always last longer than a Commodore engine simply because it's a low revving understressed engine it's like the car worlds equivalent of a Moto Guzzi.

Probably same deal for the old Kingswood motors me old man reckons they were pretty good engines but only if it was built properly in the first place.

Shame really that Holden didn't bother investing in it's six like Ford did.

I was going to say this :(

In v8's the valve gear requires servicing before engine.. But most the time both is done...My old Clevo had one head, cam, service at 300,000 had klrs tmk its still going strong 12 years latter still pulling horse float all over Aussie...

Ford design the cars to last for 240,000km's or 10 years.

The pistons still move up and down once each rev reguardless of how many there are.

ROFL.... 2000rpm is 2000rpm whether it's an internal combustion or the back wheel of a pushbike.

It's a bit like saying which is heavier, 1 tonne of Lead or 1 tonne of feathers
