rosey Posted April 20, 2006 Report Share Posted April 20, 2006 You could try back flushing it with mains tap water, the problem could be just sludge (if you are lucky). Try a hose on both sides to stop the mess going all over the engine, and try a low pressure to start with in both directions and hope for the best! Dave Quote Link to post Share on other sites
