Td04 Users And Civic Rads?????

would a sniff test work particularly well on our cars? Surely most of the vapours will escape out thro the overflow?
I think you can get some sort of chemical you mix with the coolant that detects traces of exhaust fumes.
Yeah if it was the head lifting causng it, it would show up in the coolant, as it would if the head was cracked.

I think there are two possibilities now we have whittled it down:
1) The Head is lifting although seems odd as there new bolts and not mad mad power unless they were torqued incorrectly
2) The system is pressurized due to a poor rad, blockage, water pump problem etc etc
I've told Kelly they can bring the car down to us if they like so we can actually have a look rather than speculating over the forum, other than this it is very hard to tell...

With a Sniff Tester mate as you should lol and it was done at operating temperature and as far as im concerned, if the HG is gone the exhaust gases will still be mixed in the coolant system.

right chaps and chappettes.
we've been doing some research into this tonight and we may have come up with a possible answer:
circled below is an outlet from the water jacket on the cylinder head, presumably for a water heated inlet mani.
now our starlets don't have a water heating inlet so it is blanked off
now, if the gasket was worn or damaged it would be entirely possible for boost to get past it and into the water system, pressurising it and causing the problems you are experiencing. a sniffer test wouldn't show this up as it is just pure compressed air at this point.
also, while we were doing this we noticed that the genuine gasket toyota supplied us was wrong. had we fitted it we would have pissed water all down the back of the engine
gasket that originally came with the engine, laid over the new one
note in both pics you can see light through the hole, confirming this hole is part of the cooling system as we were directing the light into the water jacket.

around that particular hole we just paste on some sealant

to be honest....i dont think that hole is the problem.....like u said before, it will just leak and as it has been mentioned before (long time ago) ....there are basically two types of manifold set ups---which u have highlighted
the most it will do with the wrong gasket is leak water....which anyone putting up the engine should realise almost immediately when assembling---and then go and get the right intake gasket (the gasket that matches basically).......as i say, just put some sealant around it.and u will have no problems
i cannot see boost leaking from there --IF done up correctly ...at worst, it will leak water if poorly sealed anyway (boost or boost not)---probably more if u have a head gasket problem and running a lot of boost,,,,only due to the additional pressure
so all of that to say, its MAY not be the real root of the problem....its just a side efftect of the real problem-----maybe

I also can't see that causing the problem, as if it was a problem all other starlet members would be having this problem surely?

the pictures i put up of the gaskets were unreleated to be honest. it was just to show there were 2 types of gasket. you would know if you had the wrong one cos water would be pouring out of the back of the head.
what i was getting at was that there is a chance that boost could get past that few mm of gasket and make it's way into the water system
it may not be that at all, but it is one possibilty

atleast its a good theory i dont think you should write it off just yet!

did they not do a 'winter version' GT, that came with yellow headlights etc? maybe that had a water heated inlet.

That's easily checked - the next Snow Version I see will provide the answer.

its all new coolant after the head being done etc!
dub-seven -- thanx for the info and thought gone into your post but surely if that was the prob about 50% of the starlets on this site would experience something? :S
anyone ever think that under hard acceleration that there is simply too much pressure in the system and it just needs releasing?
Ive been told of a few ppl that the rad cant be blocked all seems work fine/ flushes fine and also the whole rad gets warm.
Nick's just recently fitted a new rad (civic uprated rad) and has releaved his symtoms alot , altho not gone completly. so he's on about the same sort of level of us now when it comes to throwing coolant out
