Looking at getting a 1988 TII, has what sounds like a leak at the ex. manifold. What do used manifolds usually go for?



Also sounds like it could be coming from the air pump, like a unseald hose off the air pump. Makes more of a chug,chug,chug,chug,chug,chug sound, does not SOUND like it's repititious with the engine, but could be with the rotation of the airpump.



Can not drive vehicle as the trans is bad, so not sure about boost.

 

I've seen them go for $30-100 depending on the deal. Most are cracked by now.
