Question.....I only was able to idle the car in the garage.
The water temp got to operating temp on the dash guage. The oil temp didn't seem to move much. THe oil temp was always a little lower than water temp but I never noticed which got hot first and how long after they were at full temp. Just want to know if I should pick up a oil temp sending unit or not. Can anyone tell me how much after the water temp gets to normal, how long after does the oil temp catch up? |

My '85 takes about five minutes, depending on how hard you are driving. I drive the same route to work every day. I see my oil and water temps go from low to 150 degrees at almost the same point in my trip. My water hits 180 degrees or so depending on if I get caught at a light, then my oil hits 150 degrees about five minutes later. Also, I have an oil cooler, which makes a difference (heats up oil faster).

Maybe not long enough to get the oil temp up to where it needs to be? That's what I'm really trying to figure out. |

Just sitting at an idle in your garage or driveway, will take quite a long time for the oil temp. to come up to operating levels.
Even driving the car, the water temp will come up to normal before the oil temp does. IMHO, your better off not even starting the car if all you can do is idle it in the garage for 10-15 minutes. You need to drive it, to get everything up to temp.  |

When I lived in the upper Midwest and had my hot rods stored in the winter, I would start them up once a month and let them idle for 20 minutes to half an hour. I would make sure the oil was heated up. I would also move the car forward and back and make sure the tires weren't sitting in the same spot.
Then, I wised up and moved to Southern California. |

I just finished building the motor, I was setting the timing and such. The oil is fresh, as is the motor. Looking at the guages I was just wonderin how long it would take for the oil to come up. I was thinking since I'm taking it to an exhaust shop, the temp sending unit is no big deal since they're there. Thanks, I probably wasn't letting it run long enough. I'll try to drive it around tomorrow (with open headers) to see if the temp comes up. |

Yesterday, when I started the 92, the water was at 40. I didn't look at the oil but, it was probably anround 40. I always run idle to 100 degrees water before I even move the car. That takes 5 to 7 minutes. At 100 water, the oil temp was 53 ( on the digital because the analog gauge is never even close to what the digital says). If I curse slowly the 2 miles out to the highway, the water is at 150 and the oil may get to 100.
So, if you're idling for 10 min. in the garage, you just have about enough oil temp to move the car and put a little load on the oil by driving. I thing this is especially important since you have a new motor and the clearances are still a little tight. Just my opinion. We have a vintage Nascar with really tight tolerences in the 750 hp smallblock. The oil gets preheated to 140 every time before we start it. |

Nice catch, Tommy
Jsup, your oil temp is fine. If mine idles 10 mins or so the oil is still cold, but the water temp is up and fan kicks on. Don't forget to change your oil and filter after running a little bit. The goo you disturbed but couldn't get out of the bottom end, the permatex and dust from scraped gaskets, etc. will end up in the filter pretty quickly. I've seen average oil pressures drop considerably, then a new filter brings them back. Keep and eye on it, but don't be surprised if you see your pressure lower than when you first got it running. As a side note, I put in a new K+N oil filter and the pressure is more than it was with a new Fram. I always change the oil out again after about an hour of runtime on a build as well, just to be safe. |

Nice catch, Tommy I'm just going to drive it to the exhuast place and back before I change the oil. About 20 miles round trip. Tops. Lots of crap in there I'm sure. |

I'd love to hear it with open headers. I'm in PA, let me know when you are going and I'll stick my head outside and be real quiet, maybe I'll hear you.
 That 20 miles will be the perfect drive to let the oil and filter clean the engine out before you change it out. |
