Reminder : 1998 TS 2.0 litre
Anyone care to list what the tell-tale signs are of a failing head gasket apart from overheating through coolant loss?
My header tank seems to be getting up too much pressure and it does seem to smell a little "petroly" .. is this what they mean by "sniff test" ???
It's new clean plain water at the moment so it probably shouldn't smell of anything. After driving I seem to get a lot of coolant/air/gas coming into the header tank via the small pipe that runs across the back of the block.
I changed the thermostat at the weekend but this hasn't cured it ... temp gauge is getting very erratic and I think it keeps getting a air-lock. It can go from just under 90 to red line and then drops back down, then back up and down and sometimes just settles back to the 90 area. Tends to be fine with a good airflow but as soon as I drop speed the temp climbs and fan just in often on high very quickly.
I changed the cambelt assembly and fitted a new water pump in May ... but it didn't make a lot of difference to the already wild gauge and and fluid loss.
I can't really see any fluid loss. It's a bit "wet" around the top edge of the gearbox but that could also be oil from the years of use ... tried to clean as much up while the thermostat housing was off, but it was cold and wet on Monday and I probably rushed it. There are no leaks on the pipes and all clips are tight.
The only time I've seen fluid loss is when the pressure in the header tank got too much and the over-filled fluid was pushed out ...
Put me out of my misery folks ...
PS What size is the ribe-bit for the head bolts ... I am prepared for the worst ...
Although at 204,500 miles do I bother?
