Answer: A leak down or "cylinder leakage" test is similar to a compression test in that it tells you how well your engine's cylinders are sealing. But instead of measuring pressure, it measures pressure loss. A leak down test requires the removal of all the spark plugs. The crankshaft is then turned so that each piston is at top dead center .
With a leak-down tester, you can see where the compression is leaking. Connect the pressure gauge in place of the spark plug, so the positive pressure can be read. It’s important that the valves are closed when the . I've asked for another, and hopefully more accurate, compression test. I want to be careful to set my expectations for a 10-11 year old boat accordingly. I don't want to spend much more than what these year boats run.

Our build started out life as most 6.0Ls, with the base workhorse LQ4. Rated by the factory in the low 300-hp range (depending on application and year), the LQ4 featured reduced static compression (compared to the LQ9) thanks to a combination of dished pistons and sizable 71cc chambers on the 317 cylinder heads. The 408 stroker test mule started out life as a lowly LQ4 6.0L truck motor. The iron truck block was machined to accept a forged rotating assembly that included a 4.0 inch . to produce a static compression ratio near 11.0:1. Thanks goes to the guy at L&R for the balancing of the new stroker assembly and the remainder of the machine work. most all gauges read a little bit different. but a normal around 385 psi.

Obviously, where you are starting with static compression plays a big role in how much "work" you need to do to keep the engine alive on the street. The LQ9 - basically an LQ4 with different pistons to increase compression and deliver about 10 more HP and TQ - has a static compression ratio very similar to yours; so you should be fine.
Hey all I have an lq4 I want to swap into my obs but I want to get some 243 heads milled to 62cc with I was told maybe a .045 gasket. I want to run a 227/234 btr cam with 614"/.576" 113+2. . all while still bumping the compression a little more. . If you run that much cam and have overlap on it you'll have a hard time if you need to pass an . How does a cylinder leakage test differ from a conventional compression test?
