I have read all the posts about EGT probe placement. #3 Cylinder runs the hottest, however I think some people are confusing that with #3 runner counting left to right. I have seen several pics of probes mounted in the 3rd runner from left which puts it on the #2 cylinder. If I'm wrong please correct me.

 

standing in front of the car it should be.
Intake side 4321 crank pully side.

What he said.

 

correct, but I have seen a few people mount the egt on the #2 cylinder because they were told to mount on the 3rd runner instead of #3 cylinder

 

they are confusing #3 runner with #3 cylinder. I'm just trying to clear it up for others who may search this topic in the future.

 

Never seen a pic of it backwards, but i could see where there would be some confusion.

 

Can anybody explain why #3 is the hottest? I would think number 1 would be the worst.

 

I have seen some pics where they tapped the 3rd runner counting from left to right. which is actually the #2 cylinder.

 

its got warm water flowing around it , heated from cylinders 1 and 2 (water is flowing right to left)

and it also has #4 next to it.

#4 has the warmest water around it but it has more surface area exposed to water, so its actually cooler.

therefore 3 is wamest.

but the point is moot if your injectors flow unevenly. the EGT sensor will read higher in the runner that is associated with the injector with the lowest flow rate (clogged etc) cause that cylinder will be leaner.

 

I guess I never thought of all the coolent lines under the manifold I should have known that
I was just thinking something to do with air flow and fuel.

 

i am referring to the flow of water around the cylinder sleeves under the head, as well as the flow of water in the head around the combustion chambers.

 

Ok I get it. Thanks for the mini lesson.

 

#3 y0!!
