Would guess it's your cam tensioner, 19 and 20 on this.

yeah thats exactly what it looks like, guess its pops back in? hope so as the car is in hamilton and i live in auckland, hope i can drive home end of the week

and if the water pump is fine and thermo is fine, and everytime i drive it, its runs a little hotter does that mean that the head is cracked

Or you've got an air block, ask Quicksilver about that?

Check this thread out, air blocks come in many different ways as well.

Davids right, airblocks come in many ways! And that spring is simply the tensioner spring that pushes against the pulley to tighten your cambelt, theres only one way it can go back on.

My 327 had a slight bend in a hose which gave me HUGE issues, if you did read that thread my car was over heating till the cows came home, I eventually let it sit for a few days, and re-routed all hoses, then I filled the car up with water by each hose, doing a lot of squeezing and listen so that the water made its way through the block and all the hoses BEFORE I started the car, this was I was also able to bleed a lot of the air out before I got it going. Once this was done, the car started and bled without an issue.

Its not he first time I've had a bitchy m20 to bleed, they are a pain in the ass!

Edit: if its only running a little bit higher than normal that sounds more like a viscous coupling has gone in your fan.

on open road it has started to go up to 3/4 of the dial, i think it may be an airblock, atleast i hope so

An airblock would normally cause a car to overheat fully, ie needle goes all the way up, steam (if you dont turn it off early enough) the whole shabang. Have you checked that your thermostat is functioning properly and is opening at the right temperature?

Its got a new thermostat, and it was going fine for about 2 weeks then one day on the way home the needle just started raising i did a complete flush of the block and it seems to be a little cooler that it normally is but i am yet to go on a long drive then thrash it, that i will do tonight

Ah yep, make sure you get all the air out of the system first though!
