Should the dip stick tube look like this?

[ScienceBoy]

So as is was working on others things, I spotted something I've spotted many times before. The tube that holds the dip stick is fitted into another tube and into the engine block. But the wider tube appears split at the top, supported by a jubilee clip.

Is this normal?
If there's more atmospheric access to the engine oil, could this cause low pressure?

[itchyfeet]

Yes
not the origional factory crimped ring but most are long gone by now and replaced with jubilee clips

thats not a second split tube it's just a bracket, take it off and you will see

Thought you had taken a picture of mine , it's identical .

If there's more atmospheric access to the engine oil, could this cause low pressure?

Just popped in to say that the oil sitting in the bottom of the engine is not under any pressure at all and is in fact kept at atmospheric pressure by the breather on top of the engine. The only oil that is at pressure is the oil flowing into the crankshaft and camshaft bearings (fed by oil pump).

To the purists out there, ok, I know, the breather actually provides a reduced pressure from atmospheric and galleries around the filter are under some pressure, but the above is a simple guide!
