EOT magic number?

[beemerbiker5]

What is the upper limit of the EOT before you start thinking of fixing it? Or, what is considered wnl for the EOT? ECT?

Also, I know that low EGT's are good, but why?

If you have a difference of 15* your cooler are in trouble mine run ECT 190-192* EOT 194-196* some say the EOT can go to 250* for a short time low EGT means you will not have a melt down above 1300-1350* you may have turbo and piston problems it's all about gauges.

2 stroker is right. It is the temp delta you need to worry about. If that delta is more than 15* when empty and cruising at 65mph your oil cooler is clogged. Fix it immediately before you start blowing other things like head gaskets.

Lower egts are good because it is less stress on parts and it gives you more head room before temps get to the point of melting your pistons. Sustained egts over 1350 will result in a melt down. An occasional spike for a few seconds will not hurt things.

I just did a 9 hour trip stright with 5 passengers, luggage and a few Galaxie bumpers so not very loaded up. I had a delta of about 6-8* at 80-90 MPH. My oil was in the low 200s most of the time. When I drive normal my oil is in the 190s. Pulling stuff in 100* temps I have seen 220 for a bit but my coolant was righ there!

Thanks for the info!
