I’m a new vxr owner, didn’t know about the p4 issue until I looked further into the vxr. Very good video mate, could save a lot of £££ doing this every now and then 👍🏽
Hi, if I could ask, how many kilometers or miles have you had on your dash when the pressure test have been done ? Did you have any modifications done at that time ? Have you drive your Corsa WXR onthe race track till that time ? Thank you! Very good content! 👍
Xopher I think ours was injecting. There was a bit of a fuelly smell. Nothing too bad, it could’ve just been residual. Removing the injectors fuse probably would’ve helped. We didn’t think it would inject until we tried it.
I don’t think necessarily as part of it is poor inlet manifold design and part is also poor piston quality, I think it’s a number of things. When you map it for extra power you are asking maxed injectors to do the impossible, but on a stock engine you’ll just end up over fuelling. Best route is to service it every 4k miles to ensure engine is cooled thoroughly, warm it up and warm it down before and after driving, and don’t redline it. P4 failure happens at wide open throttle so drive it sensibly and you shouldn’t need to worry! If you want the extra power then forging would be better with stronger pistons and bigger injectors to cope with the lack of fuel☺️
Tiam Heydari it can range. Depends how early you catch it. It can be a case of replacing the piston or a full engine rebuild with reboring etc. Certainly not a repair you would want to be doing.
Tiam Heydari They’re great cars. The newer body shape are supposedly more reliable because they have different, larger fuel injectors. Just ask for a compression test from the garage before you commit to buy. They will be able to provide those details.
Tommy Cars&Games 97 Magnet would be a nice idea! I personally love our rubber glove improvised removal haha! That’s the fun with driveway mods! You can do what suits you so long as you don’t cause damage!

Thanks man! Enjoy the car. It’s a great fun little car!
On the spark plugs there is a little copper ring/washer, this is why they want you to tighten it to 25 Nm so that the ring is compressed ;-).
Let us know if there are any more Corsa VXR/OPC DIY maintenance or mod tutorials you'd like to see and we'll try to sort it out. Thanks for watching!
Amazing video fellas! How about removing the heatshield from the turbo, still puzzles me how to get dipstick out the way😂😂😂
Excellent thanks for sharing👍👍🏴🏴

Great content ✌🏻
Should have removed the fuse for the fuel pump too but very good demonstration
Kaniel Woodward that would’ve definitely helped reduce the amount of fuel vapour we were smelling for sure. Thanks man!
HaphazardGarage yeah definitely haha there's a diagram of fuses in the owners manual telling you which one is the fuel pump 👍🏼
Kaniel Woodward Awesome dude! Thanks for watching and thanks for the advice! 👍
Do you need to press down the accelerator pedal as your turning the key?
Pull the Fuel Fuse or Relay before doing the test.
why
@@musimir1883stops putting too much fuel into the cylinder
How good are 170 175 results ?
Higher end of average. On these anywhere 160-180/190 max. I’d say is good. Some cars have higher or lower averages though!
HaphazardGarage cheers buying a A16LER they told me it was 180bhp across the board will take that as good then thanks loon 👍
What’s the plus and negative wires on the coil pack
With our corsa e vxr its actually p1 that has a problem now not p4 like the old gen
Someone can confirm the number fuse of fuel please? thanks very much
surely when you hold the throttle wide open it doesn't inject fuel when cranking? i know a lot of cars are designed like this.

Would upgraded injectors and maybe a upgraded fuel pump eliminate the issue?

Do you push the accelerater while turning the key over?
Not needed mate. Just turning over as if you’re starting the engine.
@@haphazardgarage6439 OK cheers. Thanks for the quick reply
If p4 fail how much does it cost to repair it ?
Tiam Heydari it can range. Depends how early you catch it. It can be a case of replacing the piston or a full engine rebuild with reboring etc. Certainly not a repair you would want to be doing.
HaphazardGarage well I’m deciding to get one. After this video I’m not sure what should I do whats your thought ?

You shouldn’t use pliers to take them out next thing to do is use a magnet
