Has anyone used this to fix leaking oil seals in a diesel engine?

Supposed to recondition rubber seals safely.

I'd replace the seals & instead use AT-205 to keep suspension bushes, steering & drive shaft boots conditioned & supple.

But that would mean a top overhaul. Don't want to go that route yet if possible. If no risk to the engine I'd much rather try this, then have it overhauled if it doesn't work.

Specifically, where is the leak coming from?

Engine is burning oil but only visible at startup. Rebuilder says it might be the valve seals after they ran a compression test. Since this car has around 80TKm on it and never saw extended oil change intervals I suspect one or two of the oil brands I used shrank the seals.

I recommend that you get a second opinion.

Compression tests are usually an indication of the condition of your piston rings and valve adjustment/valve seats. Oil consumption increases as blow-by gets worse.

Another possible source of oil consumption is the turbo. If the bearings are worn down enough, it may leak engine oil into the intake. If this is the case, treat this with urgency as this is one of the more common cause for Diesel to enter a runaway condition.
