Rover V8.

[ImpJimbo]

I'm still after a Range Rover and have been looking at one local to me. Its a 91 V8 auto. Its not in bad condition but it has done over 12000 miles! Is this alot of miles for Rover V8 engines?

[hairnet]

you mean 120k?

not a lot in 15 years

long as its has regular oil and filers then no

cos they sludge up if they don't

[ImpJimbo]

I reckon I will get it. Its in fairly good nick, has new shocks all round, new tailgate and new steering rack. It does need abit of tidying up but nothing major.

was having an argument with a mate at work... in a V8 engine, compared to a 4-cylinder, do the components (pistons, conrods, valves etc) work faster or slower?

i reckoned slower, as there are more of them to do the same work. he said faster, as for one rotation of the engine you have to move 8 pistons instead of 4. try as i might i can't picture how it all works!

but a rover v8 is just about run in at 120k, they're pretty bullet-proof. Look for regular servicing and the state of the oil but you should be able to get double that if you look after it!

Formula 1 theroy has it that smaller displacement with more pistons can rev higher, thats why they use 3.8? 10cylinder engines. Is easier to stop smaller pistons at the top of the stroke. Thats why thay can rev so high. Imagine a 4 cylinder at 18000 revs.

the engines need regular oil n filter changes, to check remove the oil filler cap from one of the rockers, and check to see what colour it is in there.. If its a black oily gungy tar mess, walk away.

if its whiteish, it hasnt had a damned good thrashing for a while and will need one

if it looks fairly clean in there it should be ok.

only thing to be wary of is the cam, its the achilles heal in the Rover V8 and can wear out before 60k...


Oh and generally speaking the more cylinders in an engine, the less wear and tear there is, for a similiar powered engine with less cylinders.

Attualy your both wrong. It makes no differance as for one revolution of the crank the piston moves up and down the bore once in both 4cylinder and 8-cylinder engines.

Rpm capibility is down the the weight of the componants and the length of the stroke (shorter giving higher rpm but less torque)

Looks like we have decided to get the Range Rover. So if all goes well we will being helping to add too the huge profits made by oil companys

lpg ;D

Nice one on the Rangie!!

A V8 will wear less than a 4 cyl of similar power. A 4 pot would have to work harder to get the same power / torque figures, and these generally come at lower a rpm for a V8.
So in that respect, a V8 will wear less than a 4 pot, as the 4 pot is doing more work (more revolutions per minute) to produce the same power.
But on a single engine revolution, the pistons do the same amount of movement, so the same amount of wear.
Correct me if I'm wrong

thanks for the replies... i think i was sort of right, i'm righter than him anyway

sorry for hijacking the thread also!

[ImpJimbo]

Cheers for all the advice guys.

No worries about hijacking the thread ;D ;D ;D ;D
