[QUOTE="kzite29, post: 16639439, member: 186342"] Hi All! Here for a bit of help again.. Tore down the '99 motor and am in the process of rebuilding. I'm though the "hard stuff" inside and have a couple things to verify before I get too far. 1. Timing Chain Tensioners: The 99 has the iron ones, supposedly more robust. With about 70k on them, the tensioners seem fine to me, but when I compressed them to put back in I noticed some oil come up around the piston. Is this normal? Since they're constantly getting fed oil pressure I feel like this could be by design, but if this is an issue I'd rather spend $120 on new tensioners now than have to tear into it again later. 2. Oil Pan: The powder coating seems to be kind of flaking a bit on the sealing surface of my pan. To me, I want to say "it's not spotless, get a new one" but OEM pans are getting harder to come by these days and are pushing over $100. Has anyone just sanded the coating off and polished the surface? I also noticed some small "bumps" on the sealing surface, maybe warpage on the windage tray. They're about 5mm wide and 2mm tall, enough to feel a lump when you run your finger (whole finger, not just finger nail) over it. Is this something the fel-pro gasket can handle? OR alternatively, should I just slather this guy with black RTV and stop worrying about it? All dubious advice appreciated. -Kyle [/QUOTE]
