A little different "Spin"" on your comments regarding starting without oil pressure. An accusump certainly sounds like a viable solution. An alternative to that is a small button (normally open)used to create a momentary ground(when pushed) in the primary side of the ignition. This is pressed to eliminate ignition while the starter is spun until sufficient oil pressure is obtained then released, allowing the ignition to function normally. Used this method on 302 Chevy in friends Can Am Car years ago, and seemed to work ok. Carried same application to 1600 Twin Cam Ford in Lotus serving street duty too. This worked for us. ........Rick |
Going to have to agree with Roscoe on this... Changed oil yesterday for the first time and saw the cooler as a problem but figured out that the oil I was dumping was good anyway..
When changing oil on the boat I used to use a pump (siphon) that slipped down the dip stick hole and pulled all the oil out of the marine engines. Possilbly this could be snaked down into the hoses and pull the oil out??? They're about $30. or $40. at marine dealers... Might be an option and would be a lot easier and less messy than blowing it out... |
Rick - you are absolutely right, I used to use the "ignition kill" approach to build up oil pressure on a cold start before letting her fire up on my old car.
But since I have the accusump now (primarily fitted to maintain pressure on the track ) it doubles up neatly for starting. You still have the problem though, on an oil change, of turning the engine over quite a bit to prime the filter and lines, (and now the empty accusump as well), so that's why I pull the plugs. I would not even think about this for the daily driver (besides, I never change the oil - the shop does it), but when you have several thousand £££s or $$$s invested in your engine (and a rare one if it's a 427SO) then any little thing you can do to protect it has to be worthwhile. |
