Hi, its my first thread so if in wrong place please move it. Ive had my vrs for roughly about 2 months. Bought it used privately so no warranty it was ok, but sometimes normally on a warm day i used to get really bad engine shudder ? just like youre about to stall car, all i had to do it was turn it off and on again and it would worked briliant as usual. Ecu didnt store any codes so kinda just left it. It did happen two more times, then today on a trip to southend in traffic car started doing same thing turned it off and on again to drive about 5 metres and it happened again so pulled over and tried cranking it but it felt like it had no compression. Took timing belt cover off to see it was intact and nothing broken. Checked ecu with torque pro and carista but there was no faults once engine stood for an hour aa man came and we tried to start it again but no luck but it felt like it had compression again. Tried easystart but it didnt worked either. Out of curiosity checked top idler roller and it didnt move freely as it should it was quite stiff movement so hence my question how unlucky iam ? is it going to be head or whole engine ? thanks and sorry for my bad spelling.

If the timing belt has jumped then it's a head off job at least as the PD and CR engine will bend valves if they say hello to the pistons. May be cheaper to get a second hand head rather then rebuild the existing one, must be for a CR though as they are different (it's just the bottom end thats the same.)

 

Hope this helps a little.

Took a valve cover off today, no broken arms or anything.. It feels like i've got no compression sometimes. Will set timing to marks tomorrow and see if it has jumped. If it hasn't i'm thinking hpfp pump im out of ideas my old vag com doesn't show any codes neither does carista or torque.
