l had a new engine put into my 03 Stilo Abarth. l had fitted a new seal on the spigot shaft on the auto box but when started it leaks back out the hydraulic fluid. Is there any way to set this seal so it will not leak !!

You sure the seal was put in correctly if it is leaking already.

Try asking on Stilosport.there are a few Abarth owners on there who should be able to sort you out.

take it back to whoever put the engine in its there problem if it keeps blowing the seal out then the breathers are blocked on the box
