Seat Alhambra V6 Turns Over Fast But Wont Start

[STREDWIZARD]

hi guys,

 

sadly my beloved alhambra is poorly, for the last few weeks the voltage gauge has been reading only 12.5v at idle but  shoots up to normal once revved, so i hoped and assumed it was the battery and i thought id change it this weekend.

 

anyway this morning, very cold as it was, i went outside to start the car to go to work, only to find that it sounded like it would start but then didnt and would only spin over very fast with the occasional splutter like it would start, it sounds like no compression or the cam chain has snapped.

 

anyway i took the battery off hoping and praying it was that and put it on charge and got a lift to work, got home refitted battery and of course its the same. if i take the oil cap off i can see what appears to be a cam chain and it appears to be moving as expected, although i suspect there is another for the other bank but i don't know enough about these engines.

 

any ideas guys/girls, really not sure what else to try really.

 

thanks

scott

Your best bet is probabbly to take the rocker cover off and have a proper look whats going on underneath. I don't know the V6 engine at all, so can't say without further looking if its got a single chain or two, though theres other ways they can break so you may not be able to see the full story though the filler cap.

 

If all looks ok I'd suggest a compression test would be your next step (a tool to do this can be obtained fairly cheaply yourself, or borrow one off someone - Amazon etc can be used to find them, avoid the silverline one its rubbish!)
