Do you think this could help? Time travel to my past lol

The title is just being cute, I do not actually mean time traveling.

I had a some what but not horribly ruff childhood, well it was hard. I am planning on going back to main places that caused me pain , or places that I have good memories at, and trying to tap back into my mind set of what happened, imagine it like it were a living dream, and face it there.

Sounds a bit strange, but its no different than going back to your past , and reasoning. Its just a way of doing it. Some parts of my past actually have parts of me still here and there I believe, if that makes sense. Parts of me stayed in the past.

Maybe they are waiting for me, to come and reflect on them one on one. Maybe if I went back to those places I could see those parts of myself still there eye to eye, and in turn I could better understand the person I am now.

Maybe I can further develop my frame of reference, if I went back to the past physically mentally as the person I am now, maybe I could see what parts of me that are and are not worth holding on to are still back in that past .

Sink or swim maybe I have matured enough now to have understand things better, why things happened the way they did, but I just need to be reminded and to face it all more directly.

Maybe it would help. .

I plan on riding my bike to these places, at night and seeing if my fear of the dark, and fear of being at these places can remind me of what it felt like to be there originally and if I fantasize and try to imagine my struggles I had back in these places during the light of my youth, if I can find strength.

All I have to do is be reminded of my past, and then I can face it.

Sound like part of my problems, or part of a solution ?

Peugeot Boxer 2001 Y plate 1900d?

Hi guys,
A friend of mine owns a Peugeot Boxer 2001 Y plated 1900cc straight diesel, and today whilst we were driving along as you do, a tapping sound started coming from under the bonnet, so we had a look.
The sound, sounds like a fan blade tapping on something every time the engine turns over. – (It’s not the radiator fan, its coming from the inside of the engine) – When you rev it more and more, the knocking gets louder and louder, and more repetitive.

The sound comes from the top left of the engine (if your looking at it from the front of the vehicle) and it seems to be coming from around where you can take the cover off the timing belt.

Have you got any idea’s atall on what this could be? and a solution to the problem?

An RAC mechanic said it sounds like it’s top end. then he said it sounds like theres a problem with either the big end or small end of the piston. (But he might have well be speaking french, because I am an IT Technician!)

Thanks in advance (:

Guise,

maybe the oil pump is on its way out.
