...a large price.

<The Story So Far>

A few weeks back I bought a Range Rover EFi off ebay. It hadn't been on the
road for a couple of years but ran well, needed an exhaust, the LPG system
fixing, a few bits of trim here and there, in all a cheap but solid Rangie
for a sensible price. Drove it home - 290 miles, that was interesting. Thank
the lord for borrowed tradeplates... /ahem/

Gave it a good wash, checked everything was ok, oil was clean and to the
right level, antifreeze was ok, no leaks!, took it for an MOT, which one set
of wiper blades and a full exhaust later, it passed. Which was nice.

Taxed it on Tuesday morning, checked the levels again, all lovely, so I
fitted it with the bits I need in daily life, radio, phone, that kind of
stuff, found all the bits of trim - fuse box cover, door pocket, fixed the
headlining droop, found a new top tailgate and a cheap way of fixing the
central locking and happily mooched about all day.

Today I used it as my daily motor, drives well.. but tonight as I started it
I heard something not so nice, something that reminded me that despite
checking the oil daily I hadn't actually changed it yet, and that it used to
be run on LPG... which doesn't leave much crap in the oil, which means the
oil tends to stay clear for longer..... even when it's probably 3 years
old.. in a 175k mile engine... which brings me in a long winded way to my
point..

*the bit that matters is below this*

It's now got a light bottom end growl when cold at around 2800 rpm. No sign
of the oil pressure light coming on though, which I suspect means I've
knackered the big end bearings at the very least.

Will I get away with an oil flush, and filter change using decent oil? All
will be revealed later today.
