I was wondering if there is a test to see if some sort of Chemical additive has been used to stop coolant leaks throughout the coolant system ?

Something like Bars or Chemiweld etc , what would be the main ingredient to look for in this type of product ?

well.... any of those things leave an obvious white residue when dry in either the top of the radiator or overflow bottle. I don't know of a test for the coolant either. But more importantly, you ca

Oh noes. :/

I hope you didn't use ARP2000 head bolts... You wouldn't be the first to lift a head at that power using them.

You could be right but they have been doing these builds for yonks?

What happens? It seems to be worse when on boost for a longer periods :(

I will check it out, thanks

I've never heard of a test like you describe..

Which means that it doesn't exist.

Just because you have not heard about it , it does not mean it cannot be done.

Take water from the radiator and have it tested ?

That is why I asked for the main ingredient, makes it easier to know what you are looking for and cheaper :)

Wether or not it shows up is another question but worth a shot I guess :/

your head is lifting. If what I can only presume is loosing coolant is worsening on boost then boost is your issue, head studs.

turn down boost and see if it is as bad or none existent...

I think once again you are chasing the wrong tail.

As the lose is a slow one it is hard to know exactly what is going on. I had turned the boost off before but if you push it there was still water being lost, could be 250mm to Sydney or the same pushing 60klm

What tail am I chasing wrongly this time, I am still trying to work out the other tail ??

Just found the invoice and the studs are 1/2" ARP head and main

I would think 1/2" is pretty substantial and are used in similar powered engines, but no personal experience.

But more importantly, you can test for what is going wrong in a cooling system, it generally goes like this

1/ you notice it got way hot suddenly on a long drive

2/ you see lots of water missing and top up everything.

3/ you check the water after a few days driving and it is way low again

4/ you do a pressure test on the radiator (any mechanic can do it) which confirms there is a leak.

5/ you do a radiator gas analysis to confirm if there are any combustion gasses mixed in. If so you have some sort of head problem, if not you have a leak somewhere easier like radiator, hoses, turbo banjos, heater code etc etc. Might need a more specialist cooling system place for that

One shortcut with a badly blown head gasket is that with radiator cap off and some big revs that the radiator bubbles like crazy. Or even more obvious if you remove the oil cap and see milky oil (mixed oil and water). But these don't always happen

While it might be annoying (or lets face it, very f**king annoying on a $$$$ build) there is not much to be done if the engine was chemi welded. You can't take it back out, and it does often fix small problems.

Have checked everything every morning since the build if I have driven the car the day before. It does not loose water when not driven.

It has never got to a stage where the water temp is higher than normal. About 70-72 degrees on the MFD and just under 1/2 on the temp gauge.

Oil is clean

Water is clean and no gas bubbles when revving

The car is booked in for Monday to do all the tests, so before I jump off the gap I will wait and see, lol

As usual you are willing to jump straight in there with a wealth of knowledge and give it you all, what a great person You are so helpful :wub:


So I will race out and buy 3 and see if I can stick them all together, sort of a power packed sequential with , PT 7675 , EFR9180 and GT47R , now if that does not fix the leak , nothing will :nyaanyaa:


Turbo is too small.... Get a bigger one..... Solves every problem in the world

      Ah. OK. I take it back. I hadn't looked closely at the R33/4 arms and presumed that GKTech did as GKTech do everywhere else, which is to use sphericals there. The poly bushings are made to be 100% interchangeable, should use the standard bolt just fine. Every other bush in every other place in pretty much every other car, does.

      Steps to DIY sanding car back ready for respray....

      @silviaz Ok cool, so much easier with a video. I can see why this video would be confusing for new players.   It is obvious that this entire bonnet is going to be resprayed, have a look in the background around 2:05, you can see a bunch of bare metal on the left side of the bonnet.  It's not an issue for the primer being laid down on the non-prepped clear on the bonnet. It will be sanded off at a later stage.  This might not be obvious to new players, but working on bare metal and factory paint in this instance, the factory paint is like a mountain and the bare metal is a huge valley. The bonnet needs to be levelled flat before it receives it's final stage of colour and clear coat. During this levelling process, the primer that is landing on the clear that you are worried about will be removed.  Also, this guy is out of control. Zero PPE while spraying, maybe he is a good example overall about what not to do lol.

      Ok I FINALLY found a video lol. This took way longer than it should have as I could have sworn I saw multiple videos like this. I kept finding the completely opposite (the correct way of doing this). I wouldn't be surprised if I f**ked this up somehow.  I just realised where I've been getting confused and even with other things I work on. I haven't been doing things the regular way instead I'm going a roundabout way of doing things, like putting epoxy primer first then filler for example instead of putting just filler then primer on top of that, then wondering what happens if I get that primer on the clear coat that I haven't sanded yet. This was a bit of an epiphany 😂  But anyways, here this video. Time stamp, 2:56, some of the primer lands on the paint unscuffed above. You can see from the reflection it looks shiny.

      It does, this part circled in red. I assume the OEM bolt might not work well with the poly bushing because the dimensions may be different?

      The J arm doesn't have bushes either. Assuming that by "J arm" you mean the part of the upright that runs down from the upper arm's outer bushes to the top of the hub. That has a kingpin style bearing in it. If you meant the lower control arm, it has 1 bush, at its inner end. If you have PU in there, that is superior to Nismo rubber. If you meant the caster/tension rod - it has 1x bush at the front end, and again PU is superior to Nismo rubber. But as I said above, I would definitely get the GKTech arms for that, as sphericals slay all other options there.
