How to check a cat C7 loss of acceleration?
The best way to check is to inspect the IPR which in built inside the huei pump, and also pull the big plug on the pack of the cylinder head for the oil rail and catch the oil and inspect for metal and brass. I did not do a lot of them, C7’s but the 3126’s I did from day 1.

What causes low oil pressure in a Caterpillar C7?
This article explains 7 of the most common causes for low oil pressure in a Caterpillar C7 but the principals can apply to the majority of diesel engines. Before any inspection begins it is important to take a few precautions before tearing into the engine. Remember to keep all parts clean and free of contaminants.
What should I do if my cat C7 loses power?
It should bring up a code, loss of power, diagnostic usually starts, low boost, test the CAC, low fuel pressure, change the filters and be sure they are on properly, and the right ones, and proper pressure. The air system filter plugged, or exhaust. Turbo seized or malfunctioning, Valve set to tight.

Why does my diesel engine smoke when I accelerate?
A small puff of smoke during quick acceleration is acceptable with older diesel engines due to a lag before the turbocharger’s air flow can match the increased volume of diesel fuel injected into the cylinders.
What makes blue smoke from exhaust when accelerating?
If a diesel engine has a bad glow plug, it will create blue smoke at startup until it has warmed up. What Makes Blue Smoke From Exhaust When Accelerating? 1. Stuck PVC Valve If you see blue smoke coming out of the exhaust, all the time, PCV Valve is the frist thing you should check.

Top speed might be 35 – 40 mph. Need to kinda feather the throttle until the engine temp comes up to then it runs fine. See this thread……
Why does my 2005 Beaver C9 over heat?
Get the boost up and push cool air into the engine will help keep it cool. My Beaver 2005 CAT C9 400 HP engine over heats when climbing a hill. The Transmission Temp gauge gets up to 230 and the Water Temp gauge reaches 240. Once I start back down the hill both of the temperatures gradually return to normal.
