Plug gasket CHT sensors - generic ....?

[Jim Sower]

Hey all,

I am suspecting my CHTs are too optimistic since I am using bayonet probes on the lower regions of an updraft engine. Are there off-the-shelf (generic) plug gasket probes that I can replace my bayonet probes with? Or do I have to go to manufacturer?

 

Just wonderin' where to turn .... Jim S.

I would suggest you just going to Wick or ACS for for the spark plug type. All you have to do is make sure they are long enough and are the right type... K or J type.

<... make sure they're ... right type... K or J...

 

That's what I was wondering. I thought there were more than one type, but I didn't know how many. I guess I'll have to look up the mfgr and find out what type I have. Might as well buy from mfgr if I've done that research with him.

Thanks for the heads up ... Jim S.

You can just add 40-50 F to the readings and you will be in the ball park.

 

You can also make your own thermocouples. Buy thermocouple wire from Omega Engineering .50 a ft. for 25 ft. Silver solder the wires to a copper sparkplug gasket. J type is the most common for Cyl. head. K type for exhaust gas.
