In Topic: Running Radium AOS instead of catch can. Keep PCV?

22 March 2019 - 12:11 PM

This can has some good positives in that it 'cleans' the oil prior to dumping back into the pan which also results in clean air purged into the intake tract.   Although it does not resolve the overall issue of a poor crankcase ventilation system on our cars.   For the system to be enhanced, it requires a sufficient purge system to evacuate the medium with minimal loss in addition to a method to provide a vacuum to the crankcase.    This may help a little to remove some of the restrictions from the factory separator (depending on the hose/hardline you use...what about the primary restriction of that 10mm port on the vacuum cover?) but it will not aide in providing a vacuum.    The suction from the air inlet is not sufficient enough to provide good suction.   Therefore you are relying on the PCV system to provide the vacuum on idle and off boost conditions while resorting on the separator to simply allow gasses to escape the crankcase on boost due to pressurization.      Now think about your PCV system, it's sucking in the same non-cleansed gases/oil mixture as the can but it isn't filtered from the can.  You'll still get the oily film in your intake lines.    To me, the only measurable gain by this can is that you are putting cleaner oil back into the pan.     I'd put in a much less expensive can but have a manual drain to purge the oil.

The clean air gets routed post air filter.

It's not going to be enough.   Keep your pcv valve if you go this route.

In Topic: Cam gear offset bushing

21 March 2019 - 11:24 AM

Yes, a former member, Richie Rich, did just that years back with off the shelf comp cams offset bushings.  Most of the adjustable cam gears made up for these engines are two piece.  Most modify the factory gear by adding slots and opening up the center hole to accept an aluminum disk with tapped holes.  This one was obtained from an former member in canada, Shawn Silva

Bump

Tank is sold but I still have all of the rest.   Either carpet can be shipped.   The dash is still laying in the garage for now.

In Topic: Finally 6-bolt swapping, Axle Bolt Specs?

15 March 2019 - 02:17 PM

Hmm, you might be right.  I'll have to confirm whether or not I used 1.50 vs 1.25.  

I think this would be a good choice:  https://www.mcmaster.com/95735a631

BTW: Gr 8 is very similar to 10.9   Gr 8 is for inch fasteners, Class 10.9 for metric   Same goes for the Gr5s, the equivalent is Class 8.8. There are Class 12.9s out there as well but I've had bad luck with these in the past (on work projects).  Hydrogen embrittlement is an issue if they are plated.

I also noticed that the factory torque spec (55-65 Nm) is the standard clamping force for a Class 8.8 fastener.  Not that clamping force is key, the bolt is loaded in shear in this application.   I felt better utilizing a Class 10.9 especially due to them being fully threaded at that length.
