Requiem for a V8

[proper4wd]

Interesting about the DII thermostat. I didn't know it had a different rating to earlier Rover V8's.

A lot of good info here:

It would be possible to have a fairly good understanding of what is going on without doing a complete teardown. A compression test, leakdown test, inspection with a borescope, and inspection of the engine oil would reveal a lot.

Cylinder 5 failed a compression test. A block test showed that it's not burning coolant, thankfully.

I can't recall if he did a leakdown test, thanks for the suggestion. I'll follow up on that.

What would you look for in the oil? Metal shavings?

There will probably not be "shavings" but you may see a metallic sheen in the oil - like metallic paint on a car.

I would pull the oil pan (easy) and take a look. You can get a pretty good idea of what is happening in each cylinder in terms of scoring etc with the sump off without dismantling the top of the engine. Also once the oil sump is off maybe remove a crank and/or big end cap then check for metal particles imbedded in the bearings.
