PostSubject: Vxr turbo oil restrictor bolt..   Sat Mar 06, 2010 3:03 pm

Today if all goes well and i get the time ,i will try and change the oil restrictor bolt in my vxr turbo on my GSi and the sons vxr turbo on his Astra Gsi ...according to many views the z20let engine in the GSI.s runs too high an oil pressure from the oil pump to the turbo,which can cause oil to be blown through the turbo seals and cause blue smoke as well as possibly messing up you turbo.....the oil restrictor bolt reduces this pressure to avoid this....so decided to get two £21 each on ebay ..and hopefully fit today...hopefully it will prolong the life span of our turbo,s..

you only need one of these when you fit the vxr turbo to the let as theres more preasure in the let engine than the leh engine and they blow the seals in the turbo (correct me if im wrong)

No Percy mentioned that the VXR oil pressure is way too high. So reducing the hole in the bolt will lower this.

He mentioned that these have been fitted to cars that are blowing blue smoke then fitted them and it stopped! Also they had been fitted to race cars!

I think regal etc have started to sell these too.

The only thing im not sure about is the hole. As this is small about 3mm if that gets blocked ur screwed! Saying that if ur oil is that dirty or thick then it's been too long since an oil change lol
