MOT today Omega 2001. All ok. When lifted up engineer realized that rear brake brake tube in right side had started to leak perhaps during brake test in dynamometer. Brakes were ok. So not accepted. Have to change both of those long tubes from ABS to rear. Good

Thanks DG, yes canister case is clear. I was just thinking "while I am there" whether I should check something else, too, as it is difficult to see where the oil is really coming from.
1. Is crank sensor going to oil area or is it in a dry place.
2. Tightening the oil tube fittings agains block was in my mind, perhaps I just damage them if I touch...

Omega General Help / Y26SE Oil Leak around Oil Filter

« on: 01 December 2025, 18:18:11 »

Hello again
So V6 with canister type filter. The canister is dripping oil slightly. There is allways a drop when I take a look. Terrible place to study in floor but I took the whole canister off and found that the O-ring there against engile block was hard and brittle and tired. That is one possibility. I alredy have original spare for it. Cam covers are dry, checked with mirror. In canister area there are cooler pipes which may leak and also the area around crank sensor is wet. Any ideas how to proceed? Is crank sensor O-ring typically leaking in these enines and available separately? Does anyone know the size. I changed it perhaps 15 years ago. All ideas welcome.

General Car Chat / Re: Astra J 1.6 A16XER, Oil above Manual Gearbox???

« on: 02 August 2025, 13:13:02 »

Yes, thanks, that is possible, heard from local dealer that this version of F17 gearbox have just Bronze Bushings around selector  shaft, no seals like previous version (perhaps Astra G/H) which had selector coming from different direction and had oil seal which had to be changed when leakage occured. In J Astra the whole selector (part 1 in schema earlier in this thread) have to be replaced, no spares available. Have to remove the selector and see what is inside there if I do not find any crack on cover. Problem is that daughter drives this car 100km/day still next 4 coming weeks. I see the car once a week and control oil level in gearbox. In Sep I get the car back and try to check what is going on.

There is no pressure in my gearbox. It just hissed once as I blocked the breather with paper.

Thanks again DG for your activity here. However, due to my bad English it seems to be difficult to explain the situation in a proper way or I do not understand what we are talking about. Once again:
1. My breather is not glogged
2. My breather was not glogged
3. I glogged my breather with paper (for a while only) just to see whether the oil is coming through it.
Breather is just a stupid bolt having a hole in it from top to almost bottom. In bottom area there is another hole which is pependicular to the vertical bore, then it have a loose plastic cap, see below.
So, glogged (by myself) or not, I have the same oil leak in the area seen in pic.
I ordered new breather only because I thought that the thread of it is somehow damaged and oil is "climbing" up though it. But it was not as I heard that pressure release when opening after having glogged it. Now I am thinking that cover plate has a minor crack somewhere, have to clean everything and check where the oil is really coming from.
