That is pretty cool and generous thanks.

I am at work most days till late and only have Sunday off this week so if you want to have a look at the car and give me your opinion, would be great. I maybe saw a couple of things that need replacing.

I have also just found out that one of my friend used to do mechanic and he has accepted to teach me, starting with the basics so it is great news. It is better for safety reason.

I am looking to do a service on the car to reduce the bill of a full service before doing an MOT. My main concern after that would be body work (bit of rust on the archways and bad scar on paint job).

So all in all, great news

I think the most common mistake for novices is over tightening of bolts and nuts, which leads to small sized nuts and bolts getting sheared off or threads stripped - which then gives you a major problem!

Things do need to be tight, but it's very easy to shear things off.
Make sure you get a torque wrench, learn how to use it and make sure you do things up to the correct torque.

Some of us still shear off nuts/studs

I did it the other day on my Isuzu, undoing a nut on the exhaust manifold

I'm pretty sure manifold bolts are designed to shear off just to be a pain in the ass!

yep - spot on there bb1boy

And yep, a torque wrench doesn't help with undoing, you're right jj

at least it stops the avoidable though (doing up)

When undoing a rusty bolt or nut, undo it a bit, then tighten it, then undo it a bit more then tighten it, keep repeating until it's fully off.

I remember a cabaret act where the man did that with his trousers.

Yep - another good tip.
Just like cutting a new thread with a tap

Tap and die set has got me out of a few sticky situations. Had to re tap a hub once as somehow the wheel bolt had shed all its thread in their and then melted itself there! :S peugeot...never again.

I've used my torque wrench to get bolts undone a bunch of times. I have to breaker bars which are sometimes a bit too long so i just whip my trusty old halfords wrench out. However for exhaust work I have upgraded to a rattle gun. I dont care if it snaps the heads off, its quicker to snap the heads off then drill out the rest than it is to lay under the car for an hour strugzing to get 1 of 6 exhaust bolts off XD
