project: Oil pressure Priming 'button'
Yes this is a Duplicate for the oil filter, I posted it by accident!
Im working on a 'Priming Button' Push it and it kils the Glow plug relay/Engine control Providing the batterys up to standard, A 5 second Push'n'hold before you start the car, should bring oil pressure up for the first start of the day. After changing the oil, and 'priming' the car on saturday it took 45 seconds to bring the oil pressure up to put the light out on the dash! I should post pics and step by steps for the inexpierienced owner. Hopefully By next week. |

cant wait to see what you have been up to - did you see my post on automatic engine pre lubers?

Engine control? What engine control? the fueling is mechanical?
All you need to do it bridge the contacts on the starter solenoid with the key at O and the engine will crank. I dont see there being a lot of point though, you're still cranking the engine with low oil pressure whether the engine is running or not. Granted with the engine running its turning faster, but then so is the oil pump to match it. The only practical way to do this would be with an electric oil pump driven by the glowplug relay at start up. Which ever you used though, the engine then has to work harder to recharge the battery..... |

i suspect this is a push button that kills the glow plug circuit and i assume starts an electric pump to build up the oil pressure BEFORE you start the engine - planning on doing something very similar myself a Sureflow 45 PSI pump uses about 4 amps so is hardly going to seriously discharge the battery and this is NOT the only way to do this - google engine pre lubers or read my post with links on the oil filter thread

I still think it's a pointless excercise, i mean a well maintained example of these engines is capable of at least 250'000 miles, i cant honestly see that pre-lubricating the engine before start is going to make a fat lot of difference over using good quality oil and maintaining the car properly. I'm sorry if this is NOT the only way to do this, seems like i ****ED you OFF by voicing my opinion. Well never mind, I did say this was the only 'practical' way of doing it, sure there are loads of ways you could build up the oil pressure prior to starting, but they would all be a lot more involved - less practical.

you probably have an air leak on the oil pick up pipe in the sump , 45 seconds is far too long , no more than 2 seconds is normal when doing a filter and oil change ...

i dont think you read the post properly this is some other device that is taking 45 seconds to build up the oil pressure not the engine turning over
