oil pressure light M-5411 Universal
I have a flickering oil pressure light. I just did a rebuild a few running hours ago and may have used too much permatex 2 gasket sealant on the cylinder head gasket. Last year I tried to get a direct read gauge (was flickering then too) to replace the pressure sensor, but couldn't find the right size thread adapter for the gauge. The engine isn't running making any valve noise and I'm getting the same running and shutdown cylinder head temps. I'm thinking some of the sealant migrated. I stuck a rag in the oil fill and only found a few spatters of oil after two minutes of running at 2500 RPM.
I know I sound lazy for not wanting to run out and buy a new sender/sensor, but I've had it so far as putting my Mr. so/so Wrench hat on. I guess I'm just asking for any seat of the pants ideas for whether it's just an indication or not...the sender is difficult to reach on my boat. I think that the normal temps is a good sign. Thanks
