I wanted to see the temp. difference across the front of the engine. I used expensive infrared thermometer.
Outside air temp 68, very slight wind, no sun
I started the car and let it warm up on idle for 10 min then shut the car off. I took the following temp reading from the space to the right of each injector. Starting from the passenger side 130, 134,145
Increased rpm's to 2000 for 4 minutes until fans kicked on. Same place 168, 168, 175. I also took a reading from the upper intake bolts- passenger side to driver’s side 130,140,173. The heat also radiated down into the intake manifold causing a slight temp difference across the three.
The mount for the EGR was 170.
Not sure what these are for but there is a tube located next to the first injector and another next to the last injector. Passenger side tube 108 drivers side tube 160.
This shows that the engine has some temp ranges that could be causing the EGR plate to be hot on one end and cooler on the other. Possibly causing the driver’s side cylinder to be hot enough to handle the EGR gasses yet the passenger side to be a lot cooler.
Also looks like each cylinder has its own air temperature, which would cause each cylinder to have a different amount of horsepower.
Oil temp measured from the dip stick was a nice 82 using Mobil 1 oil.
Just thought I’d pass it along.
