This is a very common issue with metal head gaskets when they have been installed dry (no hylomar spray), or if the head and block weren't surfaced exactly dead flat.

Provided your not leaking combustion gasses this is easy to fix.

Get yourself a cheap ass ebay radiator or an old second hand one. Fill the coolant system with water, bleed the air and go for a drive to get it up to temp.

Shut it down, and VERY CAREFULLY with a very big towel or rag, take the radiator cap off. Give the top radiator hose a few squeezes to get rid of some of the water.

Start the car and then empty a bottle of BAR'S Stop Leak (Cooling system sealer) into the radiator. (Lots of auto shops stock this stuff) Top up with water and put on your cap.

Drive the car like this for about 2-4 weeks. Then drain the water, flush the system through a couple more times with water (running it up to temp each time).

Last of all, swap back in your good radiator and fill with coolant.

As a precaution, it would be worthwhile having all your head studs torque settings checked too. This is a cam covers off only job, and is perhaps an hours work at most for a good mechanic. This is an overkill check though, as if something was loose you'd have nothing but combustion gas in your radiator. Not just a little oil.

Ah thats makes a bit of sense actually.

I ran my tuner, who also did the engine rebuild and he said he would be shocked if it had done the gasket or cracked a head etc.

He to said along the lines of when the gasket was installed there may have been something wrong etc. and they will check it out no charge for me and go from there

Just an update.

Just got the car back yesturday.

All checked out fine.

Head was tested along with the head gasket both fine.

Had a compression test, come out excellent.

The cooler was leaking slightly but leaking oil OUT not in, but that has been fixed.

The little scum / oily film has been mainly put down to it being a new motor and during the rebuild may have got some in there along the lines.

So all in all, its all good. Flushed the radiator etc out for me to and topped up with coolent no charge, long story short im a happy man!

      Sorry no - The sandtrap adventure ended the day, happened at the end of the last session. At that time I wasn't hearing any weird noises nor were the brakes shuddering anymore. It was only when watching the videos that I remembered I had these sounds early on!

      Did the noise appear after your sand trap adventure? Could be something got dislodged and is playing rub rub. Even a rock wedged somewhere.

      Is there a shroud around the tailshaft spline into the back of the box? They can rub and make a horrible noise if they are not on straight/damaged. The heat might have caused it to grow too much in one direction and rub.

      Strangely I noticed it either disappear later in the day, or not be present. I definitely noticed when I was crawling around that open wheel thingy entering the pits (that part was audible in car). Driving home and commuting around town for example, I didn't hear it. It's plausible that it was a brake disc or something still slightly in contact. The brakes absolutely felt BAD for the first couple of sessions, huge amounts of shudder and grinding as they got up to temp - And then I actually just forgot about it as the day went on/didn't notice it. The videos were from the morning when this was more present than the afternoon/drive home when it wasn't. I've asked around and got a variety of responses including handbrake shoe contacting hub, CV joints, CB tailshaft bearing as above, and clutch input bearing. I didn't test if it disappeared when clutch was in. I haven't noticed it in any of the other videos nor did I notice it when driving to that extent. More or less hoping the microphone at the rear license plate giving some kind of clue of 'something' but it looks like "spin stuff and see if you can notice it" is the way forward here. I could be smart and use the gopro mic and re-mount it to that location to see if the sound is still present at low speed actually. Sounds like a decent test whenver I have the CBF'ness to drive the car again. Given it's almost 40C for the day of the track day and the next 3 days after, the CBF is high. All I've done since getting home is unpack the car, remove the remnants of the lip and undertray and left it there. I was surprised how well the PMU Club Racers actually worked. The brake performance on the track was absolutely fantastic, best I've ever personally used, no fade whatsoever and the bitiness was almost too good, I was scrubbing more speed off than I needed to, but I also ended up infield when I started trying to scrape off ... less speed.... so...

      Not really, no. Anything you would do is easily reversible.
