Hi Guys,
Finally getting the 2056 running great and took it out for a 15 minute drive around the hood. As I'm climbing a hill at about 3000rpm, I see the green light come on and I immediately lay off the gas. I check the VDO mechanical oil gauge and it's reading zero. Not sure if I imagined this part, but I could swear I heard a slight metal-on-metal friction sound in the engine for a few seconds. There was a line of cars behind me, and being on a hill, no real safe place to pull over, so I put it back in gear and gave it a little gas to get me to a safe place. The green light went out, the VDO gauge read 35 and all seemed well. Was able to drive the remaining 10 blocks home without incident and at normal pressure. I checked the grounds on the gauges and all seems fine. The light sender and VDO sender are in different places, so little chance both grounds went bad at the same time. I let the car cool down a bit and checked the oil...a quart low. I guess the slight drip from the taco plate and all the tuning and testing I've done used more than I thought. Wouldn't it be weird for the oil pump to just stop and then start again? or could that possibly be a sign of a failing pump? Or could it be something simple like driving up hill while a quart low on oil? Def something I don't want to experience again! Ideas welcome. Thanks! |

Thanks Rich. Unfortunately (fortunately) All grounds check out fine.
Makes sense that the oil requirements would be the same. I've topped the oil level off and will drive it around a bit tomorrow to see if all is well. For now I'm guessing the pump struggled a bit due to the low oil level and long, steep hill. Maybe wishful thinking...but that's the most logical explanation I can come up with for the sudden drop and just as sudden return to normal at the top of the hill. If the pump was bad, I assume the noise would be super obvious, no? Next oil change I HAVE to get that taco plate area dry. I thought replacing the o-ring this winter would do it, but nope. Ugh. Somd - just noticed your signature. Ravenna green 2258? Love that color. And motor! |

... Next oil change I HAVE to get that taco plate area dry. I thought replacing the o-ring this winter would do it, but nope. Ugh. ... Do you have the copper washers on the bolts? (Same as a type 1 oil screen washer.) BTW, has anyone ever seen a "taco plate" folded up by tightening the bolts? Mine won't do that as there is a flat surface it presses against. Something to try after getting the copper sealing washers. If it still drips get some oil stop leak and coat the o-ring before assembly. I've been doing that to pushrod tube seals, and rarely get leaks even there. Makes them swell a bit... |

Will try the stop leak coating at the next oil change. Was also thinking about a thin coat of "the right stuff"...which has worked great sealing up the 289 on my 65 mustang. |
