Paul Whiffin Posted June 13, 2013 Share Posted June 13, 2013 May as well get the engine rebuilt and stroked while it's out, eh? I just happen to have a fully sorted 3.4 engine sitting here, that'll do you Dave! Quote Link to comment Share on other sites More sharing options...

ManwithSupra Posted June 13, 2013 Author Share Posted June 13, 2013 Is the water rad in the stock location? I was a bit confused when I read "expansion tank". Not being pedantic, but it would make it easier if you were to call it a "header tank". An expansion tank, strictly speaking, does not have a pressure cap and the contents are at atmospheric pressure. You may need to add a small bore (1/4 inch) air bleed from near the water pump, and from the highest point on the water rad, to the header tank. They help stop air getting trapped and causing hot spots. Did you use a dye to look for carbon monoxide in the coolant, or a gas analyser? Yeah I meant header tank lol I wouldn't say its in the stock location as I have a V-Mount setup, I used a block tester, you know the fluid that goes from blue to yellow in the presence of CO2.

pedrosixfour Posted June 14, 2013 Share Posted June 14, 2013 Feck it mate, I say give yourself a pat on the back for catching the problem before it did any real harm, about an hour into the next track event! If you're lucky you might get enough room to remove the head with the engine still in situ if you raise the back of the gearbox as high as it'll go. Depending on the clearance afforded by the new tunnel. I don't know if I'd like to be footing the parts bill for a similar job on a Noble or Ultima. Supras can bite you in the ass but at least they don't pull your trousers down first! Quote Link to comment Share on other sites More sharing options...

Wez Posted June 14, 2013 Share Posted June 14, 2013 Sounds like you caught it just in time. What pressure cap are you running and do you have a similar setup to stock where pressure can be released if needed, ie its not a sealed system is it?

What pressure cap are you running and do you have a similar setup to stock where pressure can be released if needed, i.e its not a sealed system is it? Its running a 1.1bar pressure cap on the rad and apart from that it is indeed a sealed system (Header tank does not have a pressure relief cap on it or open atmosphere vent). I must admit I was a little confused on why the header tank does not have a relief valve or cap when I bought the car, that said though I didn't think to question it at the time.

The stock system is designed to be vented isnt it, I would rectify that, should be fairly easy to do too. Quote Link to comment Share on other sites More sharing options...

Yeah, I will need to replace the header tank anyway as on closer inspection it is has a pin sized hole in a weld now and of course the fact its swollen. So may as well turn the system back to how the stock setup works. Actually thinking about that the radiator is lower than the engine (as its mounted at 45 degrees) will that cause any issues If I was to revert it to a stock type setup? I wouldn't have thought so but its worth an ask. Quote Link to comment Share on other sites More sharing options...
chazuk Posted June 14, 2013 Share Posted June 14, 2013 Sorry to see this I hope you get it sorted soon mate , I am thinking about something like the rad setup on this track supra below . Also been meaning to ask you is having the fuel pump/lines in the boot approved ?I was looking through Steve's L build and his swirl pot and lines were mounted above the diff not sure what to do on my build. http://img211.imageshack.us/img211/6863/dz58.jpg Quote Link to comment Share on other sites More sharing options...

I assume you mean approved you mean MSA/FIA approved. No having the fuel lines/tank/swirl pot open to the cockpit is not approved, You need a firewall between the fuel system and the cockpit. I am looking at changing my tank to an ATL bladder unit in which all the fuel lines will be re-routed and the rear section sealed off. Come to think of it I may as well do that while the car is undergoing the other work. Quote Link to comment Share on other sites More sharing options...

I am guessing the benefit of the above setup is better cooling but not sure yet seems a normal rad can hold the temps okay. Yea MSA/FIA like you I will try to aim to keep to the regs as its not a bad thing to do I guess, thanks for that I am guessing one could mount everything in the spare wheel well and then plate it off and this would be a firewall ?.

ManwithSupra Posted June 14, 2013 Author Share Posted June 14, 2013 I am guessing one could mount everything in the spare wheel well and then plate it off and this would be a firewall ?. Are you keeping the stock tank? If so then yeah the swirl pot can be installed in the well and you can plate it off that should pass, although it would be best to check with the scrutineers that run the event you plan on doing for guidance on this. If you cant speak to them then you can purchase a MSA yearbook which details everything (this is the link to the 2012 book http://www.msauk.org/site/cms/contentviewarticle.asp?article=1122) If you are having a new tank installed (like an ATL tank) you will need to install the tank in a approved metal enclosure (with a sealed lid) and then that separated by a firewall.

Reminds me that I have a very rare woman very true mine would say get rid of it now dont you think you have spent enough ! i do think your going about it the right way , the preasure to bend that header tank like that must of been great and would expect any head gasket to go , some sort of preasure release may of save you in the feuture. luckly you have a spare engine if the worst happend, keep at it mate it truely is the best toy a man could have love it Quote Link to comment Share on other sites More sharing options...

I am kinda hoping the rear vibration issue is a simple fix, the prop is off on its way to get checked so hopefully its just this. Its just two fairly major problems in one go I think got me down a bit lol. But I am starting to get into mend it mode now Quote Link to comment Share on other sites More sharing options...
