Loss of power isn't. There is a saga about my adjusting timing and making a mess of it. Then having the IP rebuilt- it was leaking diesel- and also having the timing belt done at the same time.

But - there was some smoke with the original loss of power before all this. I know the timing is retarded- it's supposed to be set to factory settings. I just want to make sure she's not hiding something else in addition.

Two years ago she ran AMAZING. We did a 5k road trip with her. Something changed the last 500 miles of the trip and now she's not happy.

Ha. My 7 dollar IP pump gasket attempt turned into a full IP rebuild at blue ridge diesel and having to dive in to do the timing. Expensive lesson but gained a ton of info!

Maybe its different on a diesel, but on a petrol engine valve seals will definitely leak oil in. In my experience you get smoke on deceleration.

Gasoline engines have intakes that run at high vacuum when the throttle is closed and so oil can get sucked in.

A diesel intake is at no pressure or positive pressure. The crankcase pressure is the same or lower. The exhaust is always at a higher pressure than the crankcase due to the turbine back pressure.

I actually noticed this about an hour ago when I checked for blow by at the oil cap. I have some. Not.... a lot.... but enough to see coming out. But there was considerably less when the engine was revved.
