loose connection under the instrument cluster
took off the cluster the other day and ive noticed this loose connection. does anybody know what its for? there was no obvious plug in points on the rear of the instrument cluster

before and after valve adjustment idle sound comparison
just completed mt first valve adjustment and it was worth it. dont mind what im doing in the first video just listen to the noise. engine sounds way happier at all rpms and pulls harder (its a 200d so every bit of torque counts). every single valve was out of adjustment a considerable amount.
a lot of fucking around but with patience a monkey could do it, its actually kind of relaxing once you get a good flow going after the first few valves.

why is idle so high?
hey guys. i think im reading the gauge right but this is almost a thousand rpms right? when im driving the revs drop normally in-between shifts so its only an idle thing. no codes or anything. saxo 1.5 diesel '01

what is the importance of the F ratio (focal length) in telescopes?
Hi guys, im deciding on what kind of newtonian telescope with a dob mount to get. Im leaning towards the 10in dobsonian as it seems to be the most bang for your buck without being that big or heavy (its still pretty big and heavy but so am i), and i am drawn towards it for its light gathering abilities, and i think dobs are just plain cool. I also have zero interest in astrophotography
What this post is about, is that im worried about the short focal length (comparatively to the aperture), 250mm aperture and 1250mm focal length so an F ratio of 5. Will this cause any noticable coma? i watched Tsula's review of her 15in ultra compact obsession, with an F ratio of 4, and she decided to purchase a coma filter that was worth several hundred dollars.
I am interested in deep space but also, ofcourse, planets are pretty cool to look at as well, so
Another thing im worried about is planetary viewing. I know planets require quite a lot of magnification to be viewed, and thats why SCTs are kings for that, with their crazy focal lengths (atleast thats what i gathered). Ofcourse its hard to find out what planets look like thru dobsonians as its difficult to take images of them. People who own 10in dobs with their most popular focal lengths, what is the planetary observation like?
tldr are there any inherent negatives when purchasing a 10in dob in their most popular focal length (1250mm), and what is the planetary viewing like with them?
Also, are there any manufacturers which make the mid size dobsonians with longer focal lengths, like a 10in f8 or an 8in f8? I am in Europe so an 8 in is always 1200mm, a 10in always 1250mm
please excuse me if i made any errors i am really new to all of this

thermostat stuck closed?
as you can see i point the laser on the thermostat housing. the side which has the hot coolant interacting with it at all times is showing 70°C. The side which only has coolant flowing thru it after the thermostat is open is showing 30°C cooler. This was after a 30 minute drive on a warm night so it definitely should've opened, which would've made the temperature much more similar. The block temp was 90°C.
The thermostat was tested in stovetop boiling water before we installed it and it did open.
I think this means its stuck closed, its at 47°C probably because of ambient temperature.
Please let me know what you guys think.
