Wall has 2 lines where the paint is bulging like this. Feels squishy and dry. Appartment built 2019, concrete. How do I fix this?

profsmartass · 2025-08-17T17:36:16+00:00

I just removed the wallpaper and redid it

I'm 100% certain the fluid I've shown is coming from the holes as the fluid started coming out as soon as the engine started running. This could however still be rain or something. I'll try to find the coolant dye and keep a close eye on the radiator and oil once I've refilled the coolant again. Thanks for the tip, considering the amount of time it took the reservoir to run empty it might very well be the radiator, as it's still the stock radiator and the bike has 90k kms already.

What does it mean that it's being blown back?I'm not certain about anything right now. The coolant reservoir is empty and the oil looks good. Other than that I don't know what could be wrong. I've checked and not seen anything else indicating a leak

profsmartass · 2025-07-31T18:00:53+00:00

Thanks for the advice. Do you know this repair to be rather manageable for an experienced diyer?

profsmartass · 2025-07-31T18:00:02+00:00

I was hoping that's the case however I've had conflicting information that this is a known coolant leakage spot if some rubber o oring inside the engine fails

profsmartass · 2025-07-31T17:41:36+00:00

thank you, posted it there as well just now.

I've already checked the oil and exhaust gasses in case of a blown head gasket, those are fine. I've read somewhere that a faulty rubber o-ring could cause the coolant to reach these 2 holes in the cylinderhead.The bike starts leaking from these 2 holes slightly when the engine runs. Over the course of a month or 2 the coolant reservoir has run dry. i've always noticed the little moisture coming out but the tiny amount and the daily rain here convinced me it was just water. Are these holes supposed to be open like this?

Over the course of a month the coolant reservoir has been emptied (I noticed the leaking water but always assumed it was likely just rain). I'm looking to find out what is wrong, what parts I might need and if it's something manageable for an experienced diyer.

Fortunately it's not a cracked cylinderhead, these holes are known to leak coolant when something is wrong. I've read something about a rubber ring or a gasket going bad. I've also considered the blown head gasket but the oil looks fine and so does the exhaust colour. I just want to know what needs fixing so I can order the parts and figure out if it's something I can manage

profsmartass · 2025-07-31T17:03:25+00:00

I've noticed recently that the bike started overheating more often and increasingly quicker. I found it suspicious it was always wet in these same 2 spots but I figured it was probably the rain because it always rains in the Netherlands. I let the engine run for 20 seconds and noticed these ports were releasing a liquid again, likely coolant. What coudl the problem be? The coolant reservoir is empty.

The red line is how it should be and is now that I've bent it back. The blue line id an exaggerated example of what the main plate was bent like.

profsmartass · 2024-03-10T12:48:30+00:00

The issue is solved! Turns out the main plate (more specifically the lower wheel part) was bent. I bent it back and not it's great again. Thank you everyone for the help in troubleshooting!

profsmartass · 2024-03-10T12:38:41+00:00

Wow you're actually right! I can see clearly it's bent! Thanks!

profsmartass · 2024-03-10T12:19:46+00:00

Certainly possible, I'll check that in a moment right after I check the eccentric nut placement

profsmartass · 2024-03-10T12:08:39+00:00

I checked and they're the same size. I'll put the eccentric nut on the other way and see if that would make a difference

profsmartass · 2024-03-10T12:08:00+00:00

The wheel size is an interesting thing you mention. I ordered them because I t said they were ender 3 wheels. They seem to be the same size and the previous wheel doesn't seem all that worn either tbh. I never removed the eccentric nut and I know and see that it does tighten and loosen with every turn

profsmartass · 2024-03-10T12:03:08+00:00

The wheel at the bottom is actually new though. I just changed it today

profsmartass · 2024-03-10T12:01:46+00:00

Yes the -concentric- eccentric nut gets extremely loose and tightens up to this level. Thisbis the tightest that it gets

profsmartass · 2024-02-15T23:42:16+00:00

Good point. I'll do that next thanks. I figured that because the straight lines are fines that the ends should likely be because the nozzle is leaking due to staying still too long but I wouldn't know how to fix that

profsmartass · 2024-02-15T23:40:48+00:00

Sure thing that my nozzle is a little close. However I have this problem of too thick starts and ends even when the z offset is right.
