i stated it can be done. mellowyellow01 is the one that stated , that he done it also, and yes i have done this in the past. i have checked compression (like the book says 90% of the time, but if you are having trouble like he is! you can also do a compression test while the car is running, and i dont care how long your boss has done it the way he does it, i have been building motors for the past 20 years my self. so im not some 18-22 year kid that knows nothing, im a 39 year old mechanic, that specs every bearing/bolt and nut i install so go blow smoke up somebody else's ass..
like i stated (it can be done that way also!!!) i know what im doing , and i do my job well. with that said , enjoy..
