Thanks!!

just to add this is the third thermostat its had

I was going to say Thermostat maybe. Have you checked it is def a 2wd stat and housing and not 4WD. Have you checked the water pump just to be sure? and then bled up the system? Also check and double check that you have not mixed up any of the pipework...your brain will be telling you NO but forget that and check again.


If it was the same as when the other items were on the car I would be looking at the water pump and then making up a bung and trying to flow some air through things like the head and the water to oil cooler (assuming it has one) just don't put too much pressure in there.

hi mate cheers for the reply, it did this before the new water pump this is the reason ive changed everything ive even tried blocking the turbo water pipes and running a pipe from the stat housing directly to the header but its still not flowing. Thanks.

I think I would try and take the stat housing off and make up a rubber type disc and try to put some compressed air off a compressor in there and see if anything can be blown through then work through it.

No flow seems very odd.

yeah the top hose get boiling hot one side of rad gets hot but when you take the 2 small pipes off the thermostat housing there is water flowing out of them its a strange one like

thanks mate i always thought they would boil over if it was HG but hey i suppose it could go in a differen place. thanks mate

ive also noticed very slight traces of water in the oil (white) so you could well be right. in a way i hope it is the gasket as at least i know i can sort it i wouldnt car but the car has only done a couple of hundred mile since it was put together im now wondering if the head is cracked

i dont want a cent for advice but also check the turbo core isnt superheating the water-join the two turbo cooling hoses and see if its better over a reasonable run
i had this issue on one of the first turbo technics s205 on an evo
i will add this was promptly replaced under warranty by them via enginetuner

It sounds like you need to pull the head off...unfortunately

carterhall14@hotmail.com

so you rekon head gasket or possibly crack? cheers

Caddyshack

I doubt you will know before you pull it off, hopefully just the gasket eh?

carterhall14@hotmail.com

yeah hopfully mate, i do have spare head if its the worst case but it only measures 137.5mm so will have to work it out

v6gerry

is the engine std with std head bolts or on long studs , if so im sure you have to machine the water pump blades to miss the long stud , just a thought

carterhall14@hotmail.com

standard bolts mate
