My 2004 Marauder is long over due for major updates. I have all the Ford parts needed for this rebuild. New ford kit with chains, guides, gaskets, bolts are ready and in my case needed. The timing chains, guides and tensioners need replacement at 148,000 miles but should have been replaced much earlier. My timing chain related problems are total wear and failure. The lower driver side guide is completely worn thru with large pieces of plastic and aluminium guide material in the oil pan. I think based on the chain and guides that putting off this wear item was/is foolish. I think oil pan removal for debris removal, oil pump replacement and pickup cleaning is a must. Thank you Justbob for the tuff truth about if removal of the oil pan is necessary you must take out the engine or drop the K member. Just received the oil pan gasket and ordered more parts. Big job ahead.
