[@bigsteviesri]

Ware is all the vids Aaron hows the cars getting on.

[@michaelmatthews8171]

Learned a bit too, will be making one too to test my set up when built.Thanks for that...

[@leestephens8663]

What’s the part number for gearbox bung??

[@deanot6616]

Im stuck where my z20let engine got replaced and since doing so..my bov isn't realising the air to atmosphere like was when old engine was in...

[@AaronUnknownPerformance]

Check your vacuum lines and rear vacuum box they leak

[@deanot6616]

@@AaronUnknownPerformance cherrs mate..will doo..check pipes. Other day and all lines seemed to be ok. Will check box 😊

[@996stoky]

hey i have a z20leh and it miss fires on idle when warmed up and the o2 sensors jump from lean to rich the whole time the car is drive able but has no power up top and it shows a generic p0170 code i checked for air and exhaust leaks and no leaks have been found

[@996stoky]

ps fitting a right angle o2 sensor spacer on the 2nd o2 sensor fixed the idle but made it run rich the whole time and it was switching code from p0170 and p0130 depending on the driving in town or cruising but a local dyno centre said to remove it and bring it in after driving it for a bit was wondering what you think

[@scottsvxr]

Did you try and spray a bit of brake cleaner around the inlet manifold area (while engine is running)? If you get a rev increase you have an air leak.

[@996stoky]

@@scottsvxr tried that already however no longer have the car anymore i found out that the injectors in it where not the originals and where bigger so i reckon the idle was due to the injectors turning off

[@callumt2115]

When i am trying to test mine i am getting air coming though the rocker cover breathers ?

[@AaronUnknownPerformance]

callum T check your one way valve is working

[@callumt2115]

Aaron Unknown the one on the throttle body ? Would it be ok to send you a video on my car at the moment as i have every garage stumped and no one on z20let knows what my problem can be

[@AaronUnknownPerformance]

Message me on instagram mate

[@Supremizer]

@@AaronUnknownPerformance I've tested a z20let yesterday the way you have shown in the video. I've disconnected both breathers. with onewayvalve and the one to the crossover delete. There is air slighty leaking out of the camcover.... Knackered engine?

[@michaelrobinson7420]

Did you find out what this problem was guys. I have the same issue any info would be appreciated thanks

[@americoalmada7316]

Is it ok to use a dump valve on a vxr I heard they cause to be hi on fuel

[@AaronUnknownPerformance]

No will cause poor running due to maf sensor

[@NiallMcMeeken]

More videos of your track car mate. Keep them coming!!

[@AaronUnknownPerformance]

Defiantly will be mate! Lots of other builds too

[@max-rf6fm]

Aaron, love the vids pal. Got 2l Sri with vxr turbo, forge actuator and stage 2 map. Every now and then I get P1106 error code only seems to do it in high gear. Any ideas? I'm stumped

[@TunedVXR]

Nice video bro 👌can you send me a link for your air filter or the dimensions of it please bro

[@AaronUnknownPerformance]

Thanks man! 👌🏻 yeah no probs its a 200mm x 200mm x 80mm neck pipercross cone

[@TunedVXR]

Aaron Unknown thanks bro appreciate it👍 I did buy one thinking it would be a decent size, I did measure it thinking it would be quite big but it's like half the size of yours. I'm running nearly 300bhp so it'll be better for me I think

[@AaronUnknownPerformance]

Bigger the better when it comes to air filters mate!

[@lyndelllister452]

Hey I love your vid it was so cool I got a astra the same Mondel

[@sasamustajbasic1743]

On a stock Z20LET Engine I assume its enough to test it on 10psi, am I right?

[@AaronUnknownPerformance]

I always test around 30psi.

[@Dave__outside21]

What’s your catch can setup mate? Any pics?

[@AaronUnknownPerformance]

Hi mate. its a baffled Bailey oil breather setup not a catch can

[@TheNeedForSpeedSHIFT]

hey,love your videos,they are well put together and people can learn :D can you make a video of applying a catch can to z20let and does a stock engine needs one? thanks

[@AaronUnknownPerformance]

Thanks Raz. I can indeed, i have a baffled breather,catch cans are for catching oil residue from from breather

[@liammcfadden4308]

Great vid 😎😎👌

[@edyvalceanul6196]

I love bro z20let 😉 200cp stock

[@AaronUnknownPerformance]

Great engines!
