Hi guys , just thought I would share with you a problem that I encountered with my zetec turbo black top running a gt25 .
Firstly , this was not a complete suprise as the turbo was getting tired and smoked a bit on boost which consumed a bit of oil depending on how hard it was driven .
This was ok up until recently when I was doing the routine checks of levels and I noticed the header tank was empty so I topped up /checked for leaks with nothing visible so carried on .
The next weekend the same empty header again !! I checked the oil and it had risen and also started to emulsify and removing the oil cap showed all the signs of a possible head gasket fail . Time for action I thought !!
A full inspection and series of tests were carried out as I have spent a lot on this motor . Without boring you too much and following gut instinct It turns out the turbo was allowing coolant into the oil . A gt26 is waiting to be fitted !!

 

good choice of turbo.

 

The 26 ? Its a 26 hybrid so I hope so !! I was happy with the 25 as it spools up so quickly as does the standard 26 !! As far as im aware the 26 doesnt run out of puff like the 25 . Both can be a bit on the weak side I have heard though !!
