I was creeping along in traffic the other day, about 89 degrees out, when my oil light started to flicker on whenever I dropped the RPM's a bit when engaging the clutch. I've always been able to make this happen if I REALLY lugged the engine down, just about stalling it, but this was unusual. It started to get the point when letting the RPM's anywhere below idle (900 or so) the light would come on, and it would even blink a little at idle. Luckily I was at my destination so I just shut everything down. I checked the oil (which was fine) but the dipstick was so hot I could barely hold it even using a crumpled up paper towel. I towed the car home and let it cool down. When I started it up to pull it in the driveway everything was back to normal. The oil light turned off quickly after start-up and would even stay off for a second or two after I stalled out the engine. How bad is this? It could be something as simple as the oil pressure sender, right? It doesn't HAVE to be horrible, does it? Or should I be thinking about what kind of great upgrades I'll make during my rebuild? -Mike |

Do a compression and leak down test then report back with the numbers.

Do a compression and leak down test then report back with the numbers. Or measure the oil pressure and see how low it is getting. If you dont have an oil pressure gauge, then you probably have only the stock pressure switch that will come on when the pressure gets really low (like < 4 PSI) If you have a non-stock switch (like the VDO dual sender unit) then the switch might turn on below ~10 PSI. HF has this kit that threads right into the oil pressure port by the dist: (IMG:http://www.914world.com/bbs2/uploads_offsite/www.harborfreight.com-10819-1436640339.1.jpg) |
