What is leaking from under the throttle and the air filter box? [photos]

Hi. Gentlemen, what can leak from under the air filter and throttle can as in the pictures?

Fiat punto 1, PB + LPG, 55 KM, 1996, SX version. In the attached photos, the passenger side under the air filter can shows a black gasket and a gas cap under which supplies gas to the injection chamber. From these elements, something red, sticky flows, which, due to heat, bit into the metal of the inlet, I cannot distinguish between oil or coolant.

The coolant in the radiator tank is red in color, just like what comes out, but the oil is also a ... ginger color. A few days under the radiator cap and on the walls of the radiator where the liquid is poured, I had a reddish-colored sediment from the liquid (photos). Rust in taste and smell, I wiped off. Before the appearance of this deposit, I gave the car to a mechanic to replace the clamp and clutch plate. Once I poured oil on the maximum mark of the dipstick and the excess was blown away by pneumothorax, and from the pneumothorax it went to the filter can and it could flow down. Now half of the oil is on the dipstick but it's still leaking. The emphysema in the middle of the tube has a mini-filter made of a tangle of wires. Is there any coolant in that area, I don't think so ...

1. What is your opinion? What's going on here? Is this a throttle gasket, a gas adapter gasket (probably paper) or an air filter gasket?
2. Do such leaks also mean blowing of the head gasket to the oil channel and then pneumothorax?

It is red, there is an obvious leak in the cooling system. The system was previously flooded with plain water. There may even be a blowout on the head gasket.

Under the filter it looks like pneumothorax oil. Pull off the filter housing and you will see where the emphysema is connected, whether it is wet with oil. You can check if the emphysema is partially stuffed (wash, blow). If you want to make sure, after cleaning and washing, you can close the filter and connect the vacuum to a separate container and see if it will be clean around the throttle. It looks like it was flooded with water, not liquid, hence the sediment in the tank, as my colleague wrote above.

The cooling system was poured 0.5 years ago with a descaler for kettles and then it was rinsed twice with water, and then it was all covered with muck and flooded with coolant and so it went through the winter. In winter I did not see a red color and the car ran every day only the normal color of the fluid, now in the spring not long ago it turned red, I do not know when and it dumped a sediment under the coolant filler cap, 2 times it poured some liquid through the cap, i.e. the pressure in the system was too high even though I vented it earlier. I know that the heater is leaking, it smells in the cabin and stains the windows, so let's do it in the summer.

The oil filter housing inside was stained with oil on the odmatic side 2 weeks ago when I replaced the ignition cables, but I didn't have time to dismantle the throttle. This weekend, when the weather is good, I'll try to dismantle the entire throttle. Only what seals to buy?

Along with this issue, there is a second one described in another thread but related: click on the link: www.elektroda.pl/rtvforum/topic3327714.html#16396348 named {Fiat - Braking my engine goes out}

In order not to be too easy, there is a circulation of the coolant in Punta through the throttle body ... it's hard to know from the photo whether it is fluid or oil. The fluid feels sticky rather than slippery to the touch. However, from the photo you can see that the evaporator, which is above the throttle body, is also dirty with the liquid, so I would be leaning towards the pneumothorax oil fed to the air filter housing. Unfortunately, a large amount of oil in this place badly indicates the condition of the engine, which may correlate with the second problem. I suggest measuring the compression pressure and measuring the vacuum in the manifold at idle speed.

The reservoir cap is cool, replace it or wash it and blow it thoroughly, because in the cap you probably have valves that monitor the pressure in the cooling system, two, one allows air to be sucked in, the other to release it, equalize the pressure within the limits of the cooling system.

Do you see the description in the photos and the given pressure? Excess pressure drops the plug.
Clogged valves are too much pressure, and then instead of a stopper, the pressure will drop with the fluid elsewhere, and it may be on the throttle heating lines. You may end up spilling the fluid in a different, weaker place, lower, and with bad luck, getting rid of the coolant on the way, overheating the engine and its death.

Rinse the system with more water, you probably won't drain the block completely if you don't have a drain plug like in older cars. It is possible that the descaler is still circulating and cleaning.

Of course, I cleaned the cork and what was possible in the radiator of the red sediment.
I measured the pressure about 10 months ago, it was 11 and 12 bar on the cylinders, but I don't remember them. Hmm .. it would be best to measure the vacuum as my colleague Tzok suggests in the manifold, but I called 2 mechanics from my friends and they won't do it to me, so after the weekend I will look for others. Is there any other way to check the correct vacuum at the servo?

If there is an efficient sensor (MAP sensor) and all the wires, just connect the computer and you will see the current negative pressure in the manifold.

We write about other pressures, I am talking about the one in the cooling system which is guarded by the plug and possible ore at the throttle, You about the compression pressure in the cylinders and oil here and there.

Has it started to leak and feel after descaling or before?
I did this descaling with vinegar, 2L for 5L of water and 3 days of driving, later I poured over 30L of water, less chance of thorough washing of the stone and unsealing of the cooling system, especially with the old heater from which now somehow this liquid is leaking, since it evaporates on the windows oily . Well, I think I have a newer one, in any case the cause of the leak could be - from this descaling.
I have already read about a throttle completely covered with a stone, it is heated with liquid, I also experienced the double unfastening of the conduit to it, when a plug was made in the conduit, blocking the flow of the fluid. For me, it is venting from the thermostat housing and the engine, the return from the throttle goes to the expansion tank, and the pressure in this hose must have been good, as once it even managed to break the throttle supply hose with hot liquid.
It looked nice, a vapor cloud from under the hood, like in the movies good that at low speed, because I might not notice ...
Look, feel if any hoses going to the throttle under the air filter get hot, and think why:

The taste and smell of rust,

So not oil.

Hi. It turned out that the oil from the pneumothorax ran out and continued to fall into the air filter housing, then it ran down into the throttle body, dissolved the air filter housing and rubber sealant through which the mono-injection cables passed and continued to fly down after rebuilding the throttle. The side effect was that the car went out with strong braking, I sealed the can with silicone, put a new seal under the can and the problem resolved.

I removed the rusty rust-tasting coating under the heater cap and when it gets warm, I drain the coolant every day and replace the heater in the middle of the cabin.

Thank you for the hints, I click helped.
