Totally agree with doing stem seals properly, mine were done on my vxr before I bought it but done with the head on so I anticipate doing it properly one day, next thing to do though is gearbox rebuild :(

Hi Aaron. Thank you for this video. I have just failed my Zafira2002 MOT because of blue smoke. When I asked them to fix it they said that they can't do it (2 garages). I don't know if they don't have time or another reason( I have that filling). But your video brings me hope that if they don't want to do it I'm going to give it a try as that's the only option I have. How to do recut the valve? Thank you.

Hi mate just seen your video on doing stem seals I've got an astr h vxr 2.0 petrol and I've managed to replace everything and valve lapped it just worried about how to get the crankshafts back on and in line I've marked everything up before taking it off but I don't have the gold tool to keep them in line do I need to get one. And if you've done a video on how to get the crank shaft in line could you send me or show me where to find it thanks mate

Hi Aaron, great video. Your z20let videos are very useful. I'm going to be swapping my engine in my zaf gsi soon for the second time. Last time we dropped the sub frame which seemed to be a lot of mucking about and now have tc light on permanently. Have you taken one out before and if so did you take it out the top? Thanks again for the videos, keep them coming 🖒
@AaronUnknownPerformance5 жыл бұрын
Yes i normally take them out the bottom due to the bulk head. Is the Tc light on its own? Or is it with the abs light aswell

Hi Aaron, yes the tc light on its own. Opcom says the steering angle sensor needs calibration but can't find any info on the Internet about how to do it or even that it exists on a zaf gsi. There is a video on KZbin of someone taking it out the top, but yes the bulkhead is the issue 🖒

Owned my vxr now for about two weeks noticed when I leave it idle for around 5 mins then give it a slight rev to around 3k get a puff of blue/ish smoke , once im driving no smoke at all expect for when I hit traffic lights ect when I pull off get a slight puff of smoke is this stem seals or Turbo ? Second question is , when I had the car he said the sport button had been mapped out , it was fine on a dry day expect I went to take it out on a day where it was raining noticed that the traction controlle was holding me back a hell of a lot so I pulled over held sport button in tried to turn it off but I’ve noticed the sport button don’t work at all so I can’t get the traction control off , will this have to be altered through map ?

Blue smoke not good at all ever, could be either. Stem seal smoke better to check when just started for first time and cold. How many miles has it done?. Yes a map would sort the traction control out.
