OK, I'm getting pretty sure the condenser isn't an issue.
I left the MEK in it overnight and drained this am. Got a little bit of yellow color (IE: dissolved oil) and that's it.
Blew it out with shop air (mine is dry, I run a plasma cutter off it and have a big drier) and got nothing but more MEK.
SO, how to determine if it's clogged or clear it out if it is? I almost wish it had the old tube and fin....
OK, so it's suspect for clogging. Can't put it back in like that, sure don't want to spend the better part of a grand to get a new one. At least, not before I have too.
So out comes the drill:
3/32 holes. Easy to tig shut and same size as a 3/32 filler rod. Figuring if anything is clogged, it's likely the bottom tubes where everything would drop out. I feed in a 3/32 filler rod and it slides all the way to the end of the tube without resistance. the return and the second from the bottom tubes are the same. Feels like nothing but air.
Well, instead of drilling another 15-20 holes, I just go right to the middle tubes and check them out:
Same story; feels like nothing but air.
So, unless someone can explain to me why not, I'm going to say the condenser is clear.
Hmmm, I think I'll cut open the old accumulator and have a looky see.
Also did some quick math and forty two lengths of 26" six mm diam tubes works out to roughly .78 liters. Which is right about what the condenser held when I filled it with MEK. Sounds like it's got nothing but air in there by my rough reckoning....
