Having a dilemma as I dont no what to think
Getting a gluging /sloshing noise from the back of my dash

No ive bled the system twice

But im still getting lots of tiny bubbles in the ht when running with the cap off

Nit as bad now ive bled it this morn but its still doing it
No sloshing noise but give it 5 or 6 days and itll start again
Car has done 121k and has full sevice and records of timming belt plus other things
But no records of it ever having it having its head gaskets replaced


Bled it up by running the car with the cap off till the fan kicked in

Loads of tiny bubbles then just before the fan started two or three big bubbles were expelled
Left to cool then topped up

 

Still sounds like you need to bleed. Did you add the water slow with the heaters on full ?

 

Heaters on full and yeah as slow as pos

 

Is this a classic?

Exactly the same started happening to my JDM WRX.

Does it (or watch out for) rapid overheat ie. Temp guage goes mad after 10-20 mins, then further down the road drops back to normal before becoming rabid again?

Then BIG gulps into the header tank (cap removed) ?

If so, HG replacement time I'm afraid.

 

Its a 55 blob


Just had a sniff test done
And its head gasket

 

Oops.

Sorry to hear that.
Hope you can get it sorted asap.

 

bad luck m8

 

I've heard mixed reports about the reliability of those kinds of test.

Easy way to measure HG issues is by seeing your expansion tank fill up when you give some boost.

Is your expansion tank level higher than normal, after giving it some?

 

Loads of pin ***** bubbles when ticking over

When you rev it the header tank just turns in to a mass of tiny bubbles the it just spits it all out when the revs drop


The car stinks of coolant when in traffic as well but it never over heats

 

Any white smoke out the exhaust?
Is it actually using any water?
Is there mayo type stuff in the oil filler cap?

 

Also worth looking for any stains around the water feeds to the turbo, as if they split the water will be boiled off quickly due to heat off the turbo, but might leave some marks

 

My JDM WRX stunk of petrol through the vents when ticking over.

Since you originally said that there's no record of a HG change I'd say you wouldn't be wasting your money on having it done.

Also, if you do sell the car within the next 30k miles or so, the buyer will be more reassured that they've got one that isn't going to 'go wrong' soon after purchase.
