i would like to know wich hose leak mor often on a 87 TII. I probably have a leak but don't know where to start.



does anybody here have a solution to test vaccum leak ?



thanx

the duct between the air box and the turbo, and then the intake gaskets. the hoses dont fail that much, they just get routed wrong

easiest way i know to find a vac leak and it did work on my 87 TII



first start the car and let it idle

if its so bad that it wont idle get a friend to sit in the car with his or her foot ever so litly on the gas to keep it running at a steady rpm



secondly get a can of carb+choke (with a straw on the nozzel) and begine spraying it around the engine bay little bits at a time check the areas that where said earlier first as they will most likly be the sorce of the leak



listen for the engine's rpms to suddenly change

they change because where ever you had just spraied the carb cleaner is where your leak is and it just got sucked into the combustion chamber



this will tell you the general area if not the exact area of the leak the turn off the car let it cool and change what ever needs to be replaced

 

the duck is suppose to changed be the last owner. for the intake gasket I don't know..<



I will check the carb+chke.



for the intake gasket is the lower or the top one ?







give you some detail.



thanx

ive seen both the lower and the upper. the upper tends to get ripped when the intake is pulled off

yah, but some people dont do that

 

Some people need to buy a tube and have it on hand. I have 3-4 tubes at all times
