well. my carb'd 2.0 has about 6500-7000 miles on it since rebuilt last summer. i drive it hard and such, but for the most part it has been good. here's my pproblem- after driving like 45 min - 1hr at like 75 mph, if the car's idle drops below a 1000 rpms at a light, the oil pressure idiot light will flicker and then come hard on- so i heel toe it to stay above 1000 rpms (hot idle carb issue- working on it!!) here is what i think is happening. the stock oil pump sucks. also, i think the oil is getting too hot and thinning out so the pump has a hard time pumping.....
external oil cooler? HD oil pump? what do i do? btw- fresh oil change- proper level, 20w-50 |

Yes, it sounds like the oil is gettiung too hot, thinning out and dropping pressure.
What oil grade are you using? you may go up one viscosity and see what it does for the temps and pressure drops.... The other issue is the oil pressure relief valve. During many rebuilds the condition of it's bore and the tension of the spring are overlooked. If the preesure relief piston seals poorly, you will have low pressure. |
