Anyone have any idea why water would start pi$$ing out the overflow every time I drive hard ?
(93wrx)


HG was tested today and all seems good

 

Airlock. Had a coolant change recently? What HG tests have been done?

 

did about 5 coolant changes in the past 2 months now (the proper way) .

and they tested the water. the coolant has been in the system for about 3weeks now.

its fine if i drive slow but as soon as i boost for abit it starts pi$$ing out again

 

Normally HG issue, starts as leaking under boost which puts combustion gases into the water jacket and pushes the coolant out.

 

thanks for the input




the garage said they tested the water and all looks good . is it still possible for the HG to be on its way out and not show up in the water test ?

 

The test needs to be done right after giving the car alot of boost.

 

I had the exact same issue. Car was fine off boost for as much as you like. but as soon as you boost it up water comes out.Unfortunately That is your head gasket no question.

In the end I gave up chasing all the issues and went in for a rebuild. Strangely enough on the morning I was supposed to take it there, water went into my cylinder. After that there was no doubt is that.

 

what water test did he do exactly? compression test? coolant pressure test? bubbling overflow is sure sign of HG failure

check the bottom of the dipstick when engine is cold for telltale mayonnaise sludge

 

not sure what test they did it was the local fastfit all they said to me was we tested the water and all looks good . but will check the dipstick tomoz

appreciate the input people

think its time to see the specialist now

 

Get it too a decent garage or idealy a specialist and get a "sniffer test" carried out too find out for sure hg failer, affraid it has the tell tale sign of it it though.

 

poor car served me well

will have to see what the specialist say..
