where do i attach the vacuum gauge to do a vacuum test on this engine. want to check for possible sticking valve (or not seating valve) and general engine health.
Am about to start the engine after replacing the oil pan and then engine has stood unstarted for one year. so i want to prime engine with oil pump primer and fire it up. Would then like to do vacuum test to see how engine is performing . I did a compression test after i replaced oil pan and all cylinders were spot on except one..it may be a valve or rings ..but would like to check vacuum readings when i start it up.
Engine was running fine before oil pan change and left to stand for so long.
