what did it blow? a gearbox or diff?

[peps]

Hey guys I have a question for you, my mum was driving her POS 1987 fwd 1.6L pulsar, when all of a sudden the gearbox or diff died (I think diff blew because the car has been whining in every gear for quite some time). There was a loud clank/bang and the she pulled over. The car will not drive in any gear, clanks although the gearbox selects all of the gears like normal. It dropped its oil. (I cleaned it).

So what I was wondering before I can check tomorrow:
Does this sound like the diff?
Does the diff run the same oil as the gearbox? are they in the one case?

Is there a difference between the 1.6 and 1.5 gearboxes and diffs? This is a weird pulsar as most are 1.5 and run on leaded this one is a gxe and runs on ulp and is a 1.6 carby. Also on the rear of the car, the plastic panel there is a faint sign that says Langley (Japanese Nissan model?)

How much is a 2nd hand gearbox or diff?

I know this car is a turd but am thankful for any answers. Cheers

I don't think it really matters what is broken, a second hand FWD gearbox will come with the diff.

You may want to check this with the ET guys, but I believe the 1.6 crank goes into the 1.5 block, so the gearboxes should be the same or interchangeable.

Cheapest way to replace the scrood diff in my AE82 was fitting an entire used Jap "gearbox" (they apparently usually sell the entire transaxle, 'cos the labour to remove the diff probably costs more than the profit they make on each gearbox). That was $350, but as AE82's go through diffs fairly regularly so they'd be in demand to a degree, it'd probably be less for a Pulsar.

I don't think it's an odd car; according to Red Book, all N12's of that year are 1.6 carbied. They probably swapped the 1.5 for a 1.6 in '86 for Australia for a bit more go while waiting to gear-up for the N13 in 1987, as '86 was the first year of mandatory unleadedness.
