I had my waterpump leaking from the small hole under the impeller for around 6 months.. :(

I used to go through a full overflow bottle of water every week roughly.

The water trailed along the sump and made the leak look like it was coming from underneath the turbo.

The top radiator hose was always soft and never developed any pressure inside due to the leak.

As JIMX said if the water is not leaking out it must be leaking in,the first thing you should do is a sniffer test on the radiator coolant / water to see if there is no cracks in the cyl head.Remove the rocker cover and see if there is any visible sign of water in the head, we had a VL commodore with this problem it was using water but not overheating and on inspection the cyl head was cracked under the cam but not enough to affect the oil. Is the car blowing a lot of steam when it is cold, the most common place for these heads to crack is around the exhaust valves and the sniffer test will show this up .If the whole cooling system is working fine you should't need to top up the water at all, so there is deffinately a problem there.

Well i went into supercheap today to buy some coolant. he told me it there was nothing to worry about because:

i bought the car a month ago, the previous owner just had the car sitting for about about 4 months, not turning on nothing. So yeah he said dont worry about it. He gave me this coolant booster thing, small bottle - only 500ml. He said just drain a little water and pour the whole 500ml bottle into the radiator - i told him i'm only keeping my car for 6 months. he said that'll do. I havent been able to find the plug to release the water - still searching. If i just left the tap water in the radiator, how long before it acutally does any damage to radiator - rust?

I woudnt be going on the word of a salesman at Supercheap. Do as a few have suggested and take it to a mechanic and see what they say.

If you dont want to do this then keep removing the oil filler cap and inspecting the oil colour in the cam covers as well as the oil on the dipstick.

If you leave it too long and it is a cracked head then you will eventually do bearing damage etc etc. Then you will be up for new engine, when you may have got away with just head or maybe even a gasket. Or worse get stuck trying to sell a lemon to another person.

And someone correct me if im wrong, but the biggest prob with alloy head and tap water is corrosion of the alloy parts like head and water pump, not the copper radiator.

Give up on band-aid fixes, just take it to someone who knows (ie a mechanic) before it cost big dollars. Could be any number of things, not worth taking the risk. Even if you only plan to keep the car for 6 months, if something big goes wrong between now and then, then you will be stuck with a broken car and be seriously out of pocket.

      Seat of the pants assessment of the new intake: The car is way less "doughy" when hitting the loud pedal, especially off idle when stopped or in traffic, I did use a cheapo lazer thermal thingo to measure the temp around where the pod filter got its air, it was between 55 - 60°C, in saying this the car was shut off and not moving, so the OEM intake pipe was not supplying any fresh air to where the pod was when the car was at least moving A weird bonus was induction noise on the throttle in the cabin increased a bit,  I was worried that I was actually going to lose some of that induction noise I love so much, outside though, when I got the daughter to do a WOT drive by pass for me, the induction noise has increased alot when on the throttle, not quite ITB doort, but well up there I'm extremely happy with the results and have been exploring the country roads in the region  As for house mods: 1.New front fence is up and is awesome, it really upgraded how the joint looks from the street, and the added security is nice 2. Electricians have replace some interior lights, and with more lighting in the garage, a few new motion detecting lights out the front above the garage, front room, and at the front door, which I have already found heaps helpful coming and going, also now has fancy pants CCTV all round the house The only hold point for power though is the solar and batteries due to supply issues, although this will happen over the next few weeks 3. I have done a heap of landscaping out the front and I'm almost ready to do a new small retaining wall with some nice blocks to replace the brick and cemented in rocks around the raised garden beds cemented in river stone "was the fashion at the time" the house was built. I currently have a pallet of retaining wall blocks and 2 bulka bags of 20mm blue metal to replace the wood chip that is in the raised garden beds around the house 4. I now have 3 big raised garden beds for out the back to grow some vegetables, about 70cm high, 200cm long and 100cm wide 5. My 2 compost bins are already pretty full with brown, green and kitchen waste from the landscaping I'vedone so far, but they will probably take a few months to break down, so anything else that gets chopped, trimmed, and kitchen waste will just start filling the base of the raised garden beds to about 30cm before I start throwing 40cm of good compost, and stuff, for the vegetables to grow in, I'll need a few ton of compost and soil, but the local supplier can sent me bulka bags of the stuff Basically the logs, wood chips and a few strategically placed rocks for drainage, will give the beds some good organic materials down low to break down over time, and they will hold moisture during the warmer months to save the water in my big arse water tank if we don't get alot of rain So, all in all, the car and house mods are going well, and I'm really enjoying being retired, I sleep in too 0700 and slowly plod around inside until I feel like actually doing anything, and only work in the yard for as long as want, which has actually been alot over the last few weeks,  although when you look at it, it seems that not a huge amount of work has been done,  until I look at the before I started the work pics Happy days and good times indeed

      hahaha yeah. Plan is to get side skirts and probably just rear pods. But going to do them one-by-one. I've got a set that I really like from RHDJapen, but that one isn't shipped to AU. So need to find someone who can get it for me

      Here's an idea, answer the questions I asked you as they are trying to work out WHY the LSD will be binding up in a straight line.
