Pushrod Tube Seals
Anyone have a how to on replacing them on a 76 2.0l ? I am tired of smelling burning oil on the heat exchangers and putting an oil pan under the car in the garage.

The best way is to pull the engine and remove the heads. Then pull the pushrod tubes away and replace the seals. I use "gaskasinch" gasket sealer to "glue" the seals to the tubes, case and head. Then reattach the heads and install the engine.
There is a procedure on the Automobile Atlanta for doing it with the engine in the car. I've not tried it so I can't speak for how easy it is.

Good luck.

You don't have to remove the heads; it's a T-IV, you're thinking T-1.
The AA procedure seems pretty thorough, although I used a <a href="http://www.autobarn.net/all260194.html" target="_blank">strap tool</a> to grab the tubes verses marring them with a pair of pliers.
Clean the seals mating surfaces THROUGHLY, or they'll leak again. The Viton seals ARE a lot tighter to work with, but seal the best; #1!. I put a very small amount of grease on the seals (NO RTV!) just to make them pliable (probably all worn off by now), and no leaks, period.
Treat the sealing surfaces of the valve covers with the same respect; CLEAN THOROUGHLY. I applied some Permatex <a href="http://www.permatex.com/products/prodidx.asp?f_call=get_item&item_no=80062" target="_blank">sealant</a> on the gaskets before snapping the bailing wire back on, and they've been dry, dry, dry. Good Luck!

GRRRR! this will probaly start the wheel of how to do it right and how to make it last and this is how I did it.
So how I did it was with the engine in the car (kind of a pain) I pulled the valve covers removed the rocker arms and then push rods. each tube should slide out with a little patience. except one of the intake tubes I have been told each car is different. Anyway everyone will agree to clean clean clean. new seals Yada Yada. I put teflon pipe paste on the things and haven't leaked in 1000 miles.
