Re: Possible V6 Head gasket failure
gazza thats a really good point because the oil on the dipstick looks fine. The engine has been running extremely cold as I only do short journeys, but even on longer journeys the temp needle hardly moves going down rather than up so I believe the thermostat may need replacing. It also idles high on start up at about 1500rpm then settles after a few minutes to just below 1000rpm.(I cant remember the last time the temp needle was above a quarter, it also drops to zero when I drive instead of rising to 90). I had a stat on order to pick up today, in the end I didnt get it because before I left thats when I checked under the bonnet and discovered the mayo under the filler cap. The recent history of the car is that it started to overheat (therefore hiding the faulty thermostat I think). This was caused by a non working water pump which was replaced along with belts, tensioners, pulleys, spark plugs, cam cover gasket basically everything. Once this was done everything seemed ok. Then it started to run cold like I say, therefore my diagnosis of a faulty thermostat. Do you think changing the stat and getting the engine up to temperature would be a good start. Would I need to change the oil? Thanks for all your help as I really want to keep hold of this car. Just had a look at your website, looks like a great resource will bookmark it straight away.
