[QUOTE="TARM, post: 475776, member: 578"] Which part? The draining and evacuating of the cylinders and or the straight edge? For the first part. Where did you learn to install injectors? Self taught by just figuring it out or did you read or someone teach you? Not at all being a SA here. Its to prevent hydro-locking the engine and damaging the rotating assembly. Then consider the oil viscosity. Its not like diesel fuel. Its stays put more or less comparatively. Consider this: 1/2 quart in each oil rail. So quart total all flowing into the cylinders. Maybe more in one that another depending on the order you remove them. But for best case lets assume equal distribution and run some numbers: 1 quart is what almost 1000 cc of oil. The dish or bowl of the piston is what 40cc? 40ccx8 if they were all equal is only 320 or about 1/3 of that quart of oil. 125cc (closer to 110cc) of oil per cylinder of which the dish only holds 40cc. The rest of the oil is sitting on to of the piston. Close to a 1/2 cup. What is the clearance spec between head and piston on these engines? I honestly do not recall but something like .0055 is coming to mind. 80cc of oil in the cylinder with the dish already full would take up what 1" or so... Does not sound pretty. Think about what can happen if you start cranking the engine over. Where is that oil going to go before the valves open as the piston reaches TDC. Last time I checked the force it takes to compress oil is WAY WAY more than what it take to compress air. Maybe a starter can not create enough force before the oil can be forced out thru the valve if it does not full lock to do any damage? How far is the piston face from the head when teh valve begins to open anyways? Regardless its nothing I would ever put to chance with my engine. Besides its nothing to pull the GP and crank the engine over at the very least. For me its super easy to pull and vacuum 90% of the oil right out. Would not want to chance maybe starting a bend in a rod or wrist pin etc to then have it throw a rod and window a block down the road and have me wondering how that happened. :shrug::D:D Just having some fun. Seriously though I have not seen a single instruction set for changing a injector for any authority that does not mandate preventing and or evacuating the cylinder in some way of the oil. This is why I asked the first question about if you had basically taught yourself how to do a injector swap basically just by doing it and figuring it out as you went. I could see that. [/QUOTE]
