YAY!

I too have had a brand new core blocked right out of the box.
Now I blow dry compressed air thru everything before installing.
We have a commercial dryer (actually a small compressor/evap/condenser- Speedair brand) in series with our shop air because we need super dry air to paint cars in our booth

the funny thing is you can blow through it, it just only goes through the 1st inch or so.

Seltec TM-16HS or TM-16HD

Sanden Enhanced SD7H15

The ear-mount Seltec is available in the common 6 and 8 groove serp (10 and 12 are also available) and V-belt (1A, 2A, 2B) configurations with a 12V or 24V clutch. The ear-mount Sanden Enhanced SD7H15 with a 12V clutch is only available in A2 V-belt or PV8 serp. If your engine uses a PV6 you can either run the PV8 pulley with 2 unused grooves, or buy the PV6 pulley and swap it on. The Seltec is available in several head configurations including the popular vertical o-ring and rear horizontal pad, while the Sanden enhanced is only available in rear horizontal pad. If you want o-ring ports on the Sanden you simply need one of the adapter manifolds to go from horizontal pad to vertical threaded o-ring ports. The Seltec and Sanden with horizontal ports both use the same manifolds, so you can use a "Sanden" manifold on a Seltec or vice-versa.

Even though the Sanden is a bit smaller in displacement (154.7cc) vs the Seltec (163cc), it pumps the same amount of gas at idle, and as RPM increases it's capacity also increases compared to the Seltec TM-16. This isn't to say that the Seltec is inadequate. On the contrary, it pumps plenty of gas. It's just that the Enhanced SD7H15 pumps a bit more. Either one will get the job done. In my experience the Seltec is quieter and smoother, even though the Sanden has an extra cylinder, but the difference is tiny if it even exists at all. Reliability and longevity is a wash; they're both excellent compressors (so is the Denso 10PA & 10S series, but sadly they don't make a Sanden-style ear mount version).

One last thing: don't buy Chinese clones of these or any other compressor! Get the real deal! Real Sandens and Seltecs can be had for little more than the Chinese clones if you shop around. Chinese compressors are cheap for a reason. If the Sanden doesn't say "Made in USA" or the Seltec doesn't say "Made in Japan", go elsewhere. Don't listen to anyone who says the Chinese compressors are "just as good as" (or, laughably, "better than!") the real deal. Saving a few bucks with a Chinese compressor is false economy. Don't do it!
I see the same failure rates with OEM as I do with After Market. So go figure!

Just another kid with a sanden catalog , Tim.

Interesting that one vendor caused the Original Poster so much trouble though. Supplied an inadequate compressor for a car that big, AND a "custom" defective evaporator. And the only way the OP got the the bottom of it was coming here - for free.

I see some of these eBay customers can get 10 minutes of expert help for $14.99.

I'm guessing that hawking ChiCom crap is more profitable? Even if the failure rates were the same (if they are, it probably means a shoddy replacement job), why should I give the Chinese, who are our enemy, a dime vs an American worker? Last time I checked, the Chinese don't hire me and pay my bills. My fellow Americans do. If they don't have jobs because they've been shipped to China to take advantage of cheap labor for higher profit margins (aka greed), then they can't afford to hire me. Then I don't have a job. End of rant.

Another reason for manufacturing to be in China is that their environmental rules are more lax...

What rules?
