With respect to the filter, which is the top and bottom? Sometimes you see a black spot near the bottom where the hot air inlet from the exhaust manifold comes in. My recommendation in Australia is to remove the hot air pipe, remove the flapper valve, and plug off the hole in the side of the air filter housing where the flapper valve once resided. We don't really get cold enough temps here for that to be required, and the flapper valve can get stuck in the hot air position and cause issues.

@carnut222 I recently read in the USA they move the end of the metallic tube at the manifold and poke it towards the front of the car as an extra cold air inlet. Is there a reason you blocked it instead?

The regular inlet pipe is as big as the mass airflow meter so I don't think it needs more air, but you could do that. Just a bit messy IMHO and evidence that something's been messed with. You could poke the metal pipe out under the RH side headlight using the existing large hole there. I've also found, depending on the type of heat shielding and heater pipe attachment on the exhaust manifold, you can remove the 4 bolts, remove the heater pipe attachment bit, then re-install the heat shield and it looks neat and no evidence of a pre-heat tube remains.

I did that airbox model a couple of years ago so there's no exhaust air entering the airbox whatsoever.

@240, don't forget to let carnut222 know if the top of the air filter as it is in the photo, was located at the top or bottom of the air filter box.
240
The top of the photo is the top of the filter... but that's irrelevant anyway, because no exhaust air is reaching the airbox.

On the previous page, I posted a photo of some oil that was pooling underneath the intake manifold. Servicing the car today I had a closer look and I found a couple of bits of gasket sticking out so it definitely needs a new gasket, which is okay because I do have a spare.
My question is - how concerning is it that there is oil in that part of the manifold at all? I mean, I can understand a little bit, but this is enough for oil to drip under the car when it's parked overnight.
(Before anyone asks, yes the PCV system is perfect - I've replaced or cleaned all components including the breather box and flame trap.)

What were the items you cleaned or replaced? The PCV entire system is cheap enough, you might as well replace it. Especially the breather box (if you're keeping the car)
240
Yes I just said that I've replaced the breather box. Along with the flame trap, and I've thoroughly cleaned all the hoses.

Nice car. Sounds like time to pull the inlet manifold and inspect the inlet ports for oil. No healthy engine should be leaking oil from the inlet ports. That would be a sign of excessively worn guides and valve stems or valve stem seals at minimum.
For most engines I have ever encountered at this stage, regardless of brand, I would assess for cylinder blow-by (crank case pressure while running) and if okay - remove the head for reconditioning. Maybe you can get away with just replacing the valve stem seals, but often when they have aged to the point of dis-integration you might be dealing with other areas of wear also.

What's the oil consumption?
240
I probably will pull the manifold to change the gasket anyway, so will have a look then, which I suppose will help narrow it down a bit.
(As an aside, can I just put the new gasket there between the metal surfaces or do I need to apply a sealant as well?)
What's the best way to test crank case pressure? I have read methods of holding a plastic bag or rubber glove over the oil filler hole, I might try that test.
Oil consumption could be better but isn't too bad, it uses probably about 1 litre every 5000 km.
ramrod
That oil consumption is considered normal.
You don't need to put anything on the gaskets, as long as the mating surfaces are clean enough to eat off. Read: Brake cleaner

I replaced the manifold gasket today.
It didn't look anywhere near as bad inside the head or manifold as I was expecting. I assume the reason I was getting oil leaking out was just because the gasket was bad enough to let out any oil spray that came near it, and it must have accumulated over time.
But I could be wrong, happy to hear other opinions
(First picture is looking inside the manifold, second pic is looking inside the head, third pic is the old gasket still sitting on the head)

Pretty normal looks like a bit of reversion

Far out I hate 240 lights
The RH brake and indicator lights are on faintly even though the car isn't running, and they stay that way when I unplug the connector from the light!
Do I assume there is a short between the earth and something?

Wow if they glow faintly with the light connector removed, I think you’re parked under a high voltage power line LOL! Need to test it at night as it seems impossible for the lights to be on if the connector is unplugged...unless somebody has bypassed the connector and attached some wires directly to the globe holders (I’ve seen that done before)...
240
That hasn't been done, although a previous owner has bodged some of the wiring to splice in the trailer wiring connector.
I will try at night, although in any case it was definitely glowing faintly with the connector plugged in so something isn't right.

Could definitely be a bad ground causing the faint glow. I’d recommend checking all the grounds for the lights including the front ones as even something wrong up front can cause issues with the tail lights since they’re on the same circuit. It is frustrating but if you go through it methodically checking grounds, cleaning any terminals and globe holders, and fuse terminals as well, you should be able to sort it. And might pay to locate a 2nd hand bulb failure relay thing to swap out to confirm that’s not the culprit.

I found a Dave Barton grille badge sticker that I bought ages ago.
