I looked around for a compression test kit, but the only one I found that specifically said it was compatible with the Penta MD series was the OEM kit for ~$800. My understanding is the sticky wicket is getting a compatible piece that will screw into the Volvo injector port, that’s why people...
The OEM kit and adapters to do a compression test are very expensive. It's possible to use an injector with the innards stripped out as an adapter. Any ideas on sources for nonworking injectors? It's a Volvo 833191/Bosch KBL 87s78/4
