engine tin removal Options

[pda914]

Is it at all possible to remove the engine tin over the oil cooler and temp sensor without dropping the engine? I need to get at both the oil cooler top and I need to replace the temperare sensor.

If so what should I look out for?

I put a custom fuel injection setup and am using a megasquirt engine management system on it. It works fine but the cylindar head temp sensor is very nosy electrically, I will be replacing it with a type K themocouple together with a themocouple amp with offset correction and some op-amps to make it act like an thermister with a negative temp curve that the megasquirt expects. This will isolate the temp sensor from the engine ground that electrically noisy.

I had put an extra duct in the heater blower to go to the other side. It slipped off its mounting and got sucked into the impleler. I pulled a mess of wire with sheaded plastic out of the impeller and since that event the oil temp has been a bit warmer that before. Since I need to access the temp sensor on that side I can inspect the top of the oil cooler for plastic bits that may be blocking some of the area,


That front tin pieces you sold to me a few years ago has been installed and is working fine.

How much noise are you talking about? I assume you are using the CHT for the coolant temp signal in Megasquirt. If so then you most likely are only using this for warmup enrichment in which case you would need a pretty major swing in the sensor reading to actually have a problem, so aside from getting nice pretty graphs in your data logger I don't know what else you would be accomplishing here by changing your sensor..

How bad are the fluctuations in the reading? I run the stock CHT sensor grounded its normal way through the block without issue.
