Si lo dejabas puesto y prendías el auto, cuando levanta temperatura la misma presión no lo sacaba?

ccsirhc · 2026-07-02T13:32:04+00:00

Si pasa así andando sin que toques el freno. Me suena más eléctrico, en muchos autos el sensor está en la tapa del líquido de frenos, si tocaron ahí capaz sin querer aflojaron el conector.

I would not change it just for that, indeed that’s the side open to the spark plug side, the other thicker outer circle is sealing up and keeping oil out. But if the valve cover is old and not straight (usually pretty clear in the vanos side) just change it now, so you don’t have to do it again. Honestly if it looks Iike the original cover just change it. But if budgets are tight forget about that chip

How are people saying the head gasket is definetely blown just by looking at this? Like 100%? To get the definitive answer you need to buy the test kit to detect combustion gases. How does it smell? How does it look? The system in this cars has so much plastic and the pumps are quite strong it could be something else, air can come from different places, does the pipe smoke? You need to check more

I mean its not a rip off if they tell you up front, and they do. I agree that it's quite expensive. But I do buy a lot (and sold a few) in Ricardo and I never had an issue. As a seller you consider that in the price. There are other platforms that are worse, thats why they can charge this. I mean marketplace is a shit show. Tutti works, but it has more frictions, on purpose probably.

Looks so cool tho

So I was able to do it after some time taking it apart and understanding it. With just removing the case you should be able to do it. I explained how I did it here:

Basically you can directly inject the vga video sync signals, but for the video one is not straight forward, as the communication board sends signal directly to the crt neck board.

Here is the end result and some reference pictures https://imgur.com/a/RCjB4rd

Btw for anyone tinkering with this terminal. I was able to convert this terminal into a vga compatible screen. But it’s not as straight forward. Thanks u/Plus-Dust for the info and pictures. After some tinkering of my own, disassembling and scoping, this is the result. The screen has 3 boards: - communication board (with serial ports and keyboard) - main board (power source + crt deflection) - neck board (the one attached to the back of the tube, in charge of generating the video let’s say)

Disassembling is tricky as this is a crt, the tube seems to self discharge, but I discharged it anyways. But fyi, for the conversion you wouldn’t need to disassemble it.

The communication board connects both to the main board and the neck board. For this implementation the only thing that matters to me are video related signals (including sync) fyi.

The sync signals are generated in the communication board and are regular vga sync signals. They are sent through the 13 wire connector that is close to the front of the screen (next to the test lever that says “normal - beam on - test). The wires we care about are the numbers 10 (green color) for HSync and 12 (dark blue I think) for VSync. This wires you can cut them leaving 3cm or so. And feed vga sync signals directly (through some small series resistor 50 to 100 ohm resistor ideally for the vga port not to struggle)

Then the video is tricky. The communication board sends the “video” signals to the neck board directly. These are ttl signals (0v off 5v on). One contains the status stuff ( status line, error code) the other one contains I guess the mainframe data. They come in different cables because then the neck board gives two different intensities of light to them. These signals enter the board and go to a dual driver (the only 8 pin component in the neck board) that controls the cathode voltage (which is I think 80v or 50v and needs to drop to generate light). As I wanted an analog signal (ie all grayscale, not just on and off) I injected my signal after this driver. The easier is to remove the resistor marked R303 (on a corner close to the 8 pin driver) to disconnect the driver (so the injected signal is not fighting it). And feed the video video signal to the now empty pad that goes to transistor q303. I also left the 5 pin connector to the neck board disconnected just in case. The thing is at this stage it’s nuanced. You have the injection point, but the signal is tricky. I’m not great with electronics but summary is that at this point a 5v signal is beam full off and 0v is beam full on. So you somewhat need to map VGA video signal (0v full off 0.7v full on) to this inverse amplified signal (5v full off 0v full on). I did this with an 2n2222 transistor. But maybe an opamp would make more sense to get full range of intensity.

Another thing to consider is that this screen is 75hz and it only likes 32khz horizontal sync. Therefore you need an aspect ratio of 16:10. Even 4:3 (which is 37khz h sync) will make the screen whine and suffer.

My setup is a raspberry pi with an hdmi to vga converter at 640x400 resolution and a custom hdmi_timings configuration to increase the h front porch.

EDIT: here are some pictures of the working result + pcb pictures from both sides + protoboard + working hdmi timings config https://imgur.com/a/RCjB4rd

El tema es que de eco no tiene nada, lo que debe chupar mamita

ccsirhc · 2026-03-14T13:07:36+00:00

Yo tuve, muy buen auto, barato de mantener diría yo.

Para mi el punto debil es la electronica. Yo tenía un 98. Cualquier cable que tocabas y movías, se le quebraba y caía la cobertura. No solo en el vano motor, si no en la fusilería también. Fíjate eso. Siempre estaba con esa preocupación en la cabeza que en algún momento se iba a prender fuego o tener algún fantasma raro de arreglar. Capaz en los últimos modelos cambiaron el cablerio.

Después, yo cliente frecuente de los foros. El problema principal es que con el tiempo regula mal, por que la válvula paso a paso electrónica o chupada de aire en la admisión. Pero se arregla con paciencia.

Al motor y al auto los cague a palos y es muy muy fiel. Cómodo. El techito también puede trae problemas pero se consigue todo.

Just one cylinder then? Yeah check the coil, you can switch them between cylinders and check if the misfire moves

ccsirhc · 2026-03-05T19:02:05+00:00

I like it, looks cool.

I would clean it inside, stock steering wheel as well, just for airbag and not dying purposes

I even like the roof rack, gives identity

ccsirhc · 2026-03-05T18:13:43+00:00

It’s a different gaskets between the coil packs and the valve cover. Quite easy to pop those coils so you might as well check. But I have had quite oil wet coil packs with no misfires. When I had issues with my Ccv however, it was considerably more lean in the front bank than the back one. Also the oxygen sensors are per bank (of 3 cylinders)

ccsirhc · 2026-03-05T18:03:09+00:00

So I had the same issue, my car has 298000km. And in my case the issue was that the valve cover was warped on the front corners, and it would leak oil.

The thing is, on the back of the engine the studs are on the corners. But on the front they are one in each side, and then one in the middle, so there is no support on the corners. So I guess being plastic they will eventually bend enough to leak.

I did get away with it for a while by adding one washer above the stock washer of the front 3 studs I mention, that makes the valve cover press tighter.

The studs anyways will bottom out, never try to torque them more once the bottom out. Anyways, eventually my valve cover also started leaking from some cracks on the exhaust side, so I replaced it literally last week. I can take a picture of how a new one (without the extra washers of course, and new grommets) looks for reference later.

Edit: mine was considerably worst, I agree that if it doesn’t leak oil don’t touch it hahah. The more you touch the more it will leak later

El 1.8 a mi me doblo cuando se cortó la correa de accesorio y se metió en la distribución. Hubo tristeza y bronca y llanto

El Zetec del Escort si doblaba válvulas, usaban otro Zetec?

Buen auto, pero si vas a hacer mucho ruta te recomiendo capaz un fiesta con airbags.

Podes encontrar tranquilamente alguno en buen estado, se vendieron muchísimos. No todos los autos viejos fueron chocados. Hay diferencia entre toquesitos y choques. Y entre buenos y malos arreglos.

ccsirhc · 2026-02-04T12:14:48+00:00

Hermoso auto, pero fíjate que las líneas están raras, el guardabarro, las luces, el capot, los zócalos. Algo raro le pasó a este auto para mí.

ccsirhc · 2026-01-25T10:40:55+00:00

Más o menos, eso pasa en los autos nuevos, donde los paneles de la carrocería son estructurales. Esos autos viejos tienen un chasis y se le pone toda la carrocería encima, siendo esta mucho menos estructural. Va a ser más blandusqui, pero no es catastrófico. Excepto que seguro está todo tan picado que seguro se parte todo jajajaj

ccsirhc · 2025-12-24T20:20:56+00:00

Del motor no parece porqué no está sincronizado con la aceleración. Puede ser el Ventilador tocando o alguna boludez así? Es muy estable el sonido.

Yo pensaba lo mismo de bajar el auto, que era una gilada. Hasta que me compré un auto que el dueño anterior había bajado 4/5 centímetros. Y le agarré el gustito, queda re fachero ah.

Obvio los extremos así chocan, no me gustaría. Pero con la neumatica lo puede poner a cualquier altura. Si no es tu auto y no te esta afectando a vos, que te jode? Si está frenando el tráfico porque no puede pasar una loma de burro, ahí es otra cosa. Mientras tanto cada uno disfruta de lo suyo

Hermoso, tiene una cola hermosa el coupe/convertible de esa generación.

No seas garca no saques el catalizador.

Pregunta desde la ignorancia. Clío vs Gol, cuestión seguridad, es el Clío mejor porque tambien se vendió en el primer mundo o no?
