I have the ferrari turbo test results. FAILED! Big time. My question is; did I do it right? My assistant and I replaced a coolant leak under the intake plenum. Started up the car and got the usual smoke and oil. After a while the car heated up and was running very well. (much less smoke and oil and steady idle, if you read past post by 4returbo Big improvement). With the car heated up we started the test.... Wait can't find the only socket that will get the plugs out. After a trip to Sears (engine not cold not hot) all plugs are out we start the test. In a nut shell he turned the engine while I watched the gage. 100% leak... he keeps turning 80% keeps turning... 40% ... 15% ... 12% ... 12% ... 30%... 80%.. get the picture? We did this until the min percent was reached and held. My results.... Sad to say. 14% 15% 29% 14% 13% 37% 32% 38% Would the results be better if the engine was warmer? Are the results valid with the method we used? Needless to say I am going to perform another one and listen for air leaks in the exhaust, intake and valve covers.
