Volvo D2 75F Waste-gate stuck

We got a Volvo D2 75F. It’s 3 years old and has around 400 hours. For the first year I could get 2800 rpm under full throttle. Volvo recommends to run the engine wide open every 10 hours to prevent carbon build up in the turbo and waste gate. I noticed that in the second season we only got 2700 rpm. I could not quite figure out why. This fall when I did the oil change I noticed that the 2” hose clamp that holds the rubber hose that connects the turbo out to the engine intake slipped off and therefore would lose some of the Turbo charge. At that time I realized that the Waste gate is firmly stuck. Questions. Does anyone have the same problem? Since everything seams to run fine, would it create problems if I keep running the same way? Is there a way to free the Waste gate without rebuilding the turbo for $2000.

Re: Volvo D2 75F Waste-gate stuck

Waste gates jam up quite often but usually in the closed position so there should be no loss of turbo boost or efficiency but it would be nice if it worked. For a drop of only 100 rpm at full throttle there could be many things to explore ...starting with the propeller health and working up to fuel filters, air intake filter and engine control cable adjustment.
Hope you find the missing 100rpm

Re: Volvo D2 75F Waste-gate stuck

thanks for the reply. the waste gate is stuck in the closed position. The turbo charge loss is at the flexible rubber connection. I did put the hose clamp back in place but as soon as I go over 2600rpm the hose balloons and pulls the clamp off again. Too much pressure.so basically the rubber hose acts as a waste gate. The question is. 1. will it create problems down the line? 2. is there a way to free the waste gate without pulling everything apart?

Re: Volvo D2 75F Waste-gate stuck

Whilst looking for information on the waste gate found this at YBW.com.

https://forums.ybw.com/index.php?thr...-turbo.431360/

"Just had to rebuild my wastegate on my d2-75 turbo caused by a volvo penta casting fault on the exhaust water injection elbow. The bottom fixing point of the casting obstructs the waste gate from opening and requires grinding away if you want the waste gate to ever open. My engine has done less than 300hrs!! It's worth checking all you d2-75 owners, just put your hand under the turbo from the port side and tug the wastegate actuator bar it should move towards you approx 15mm."

Re: Volvo D2 75F Waste-gate stuck

Over boosting from a stuck closed waste gate is NOT a trivial matter. Too high a boost can seriously damage your engine.

It's not just "nice it if works"--it is vital to the longevity of your engine!

Take it to a turbo shop. Have them fix and recalibrate it for you.
