PCV Air Pump

Well I took some time off from the porting to let some of the aluminum dust settle. Also to give my compressor a little bit of a break.

A rainy day and all I decided to fix the $20 Denso smog pump that I bought a while back. My thoughts are to use it as a mechanical crank case ventilation system. Considering there probably isn't going to be enough vacuum to do it as per usual.

Used a puller and got the thing opened up, it was a little rusty around the edges. After a bit of cleaning it was as good as new.
Pulled it completely apart to give it a thorough going over.
Gave the inside a quick wipe down. Didn't want to use anything to abrasive and remove any material. I wasn't able to find any way to adjust the clearances of the impeller blades.
All cleaned up!

Found that it was the front bearing that was a bit messed up.

I don't think it was the original one ether. Looks like it was a quick fix. The seal on the back side of the bearing was dented. I removed the seal and a few of the retainers were slightly crushed. So I'll pay the $5 for a new bearing and press it in. Hopefully that will be the fix to my $20 PCV pump.

Mounting this pump under the alternator using the A/C bracket will be the next step for this system.
