Ok i searched and read all the articles about oil restrictors and a lot of them have a link I guess about an article Samnavy created about this issue but that link no longer works.

If someone has details as to what i do with the 1/8" rivet to make it an oil restrictor that would be great. The turbo is a china version of the 2870 ran great for the first couple months but now randomly at idle it will start smoking out the tail pipe but when I start driving it stops smoking and on my stock oil pressure gauge I am seeing 65psi+ of oil pressure around idle and sometimes almost 80 under heavy acceleration.

Do I just get the pop rivet and stick it in the turbo as is or what?

 

remove the stick.

drop the rivet head onto the fitting.

crush the flat flange around the 45* taper of the fitting.

install the feed line.

 

and actually... his post is still there and his pictures still attached.

Thanks for bringing this up, I've never heard of this but seems like a perfect easy, cheap, effective solution.

 

I had to take a dremmel to my fitting and to the rivet(around the edges) and it fit just fine in my chinacharger.

 

I'd go with a real 1mm restrictor every day. I used on for a day or two but would not risk it again.

 

.035" is the number you want.

 

Thanks brain, for some reason the link in the other threads kept giving me a 404 not found error.

 

As for the size, do I need to run a .035 restrictor or what? The 1/8" rivet is .075 correct? Just want to make sure I get the right one without starving it of oil or blowing seals.
