Re: [T3] My new fastback


Last time I had oil coming up the dipstick tube, I had a hole in a
piston.  Air got pumped down through the hole and blew the oil right
up.  Came out a hole in the dipstick boot and got on the muffler,
major smoke screen.  You might do well to check your compression all
the way around, not a bad idea upon acquiring any used car.  You might
have a bunch of blowby.  There's a breather box on the right hand side
next to the air cleaner, it's supposed to separate oil from fumes and
return the oil down a tube to the dipstick/filler fitting on the
bottom rear of the engine case.  Fumes get piped into the air cleaner
through a short hose.  That's the theory.  Mine's a '71 and I think
it's got the same setup as yours, when I first got it, the plastic cap
on the top of the box was hopping around like a pressure cooker
weight. Got a new cap and things became cleaner. Must be a common
problem, I've seen any number of wrecks that had monster screwsI*u pipe plugs and Brillo pads stuffed in there.   There's a short
section of rubber hose between fan housing and engine case on the
right side that connects the breather box with the dipstick fitting,
it's hard to see and probably impossible to replace without an engine
pull and partial dismantling.  Mine was disintegrating when I got
around to changing the engine, another possible source of oil leaks.
Anyway, I also need a new dipstick tube boot, the ones they're selling
for replacement  are crap.  Kind of a semi-soft plastic bellows thing
that gets hard and melts in a half-hour of running.  It also leaves a
hole in the rear plenum for hot air to get sucked out of the engine
compartment by the fan.  Anyone know of a source for NOS?
