Hi-Long time reader, first time poster. I have a 90 loyale engine that broke a timing belt. I thought, "while i'm here" I would pull the engine, do the clutch, pull the heads and do the valves (leak down confirmed 2 leaking exhaust valves, but good rings.) I was thrilled to find aftermarket gaskets and hone marks in the cylinders, along with an incredibly clean engine. So, valve job, remove and degum lifters with carb cleaner per manual, new head gaskets, new oil pump seals, new orings in head, clean check valves, new t-belts, back together. Great leak down, smooth idle, and an ear shattering clatter in the driver side cam housing. So, MMO to the rescue. 300 miles, still rattles. Constant, indepedent of oil pressure, which is 45psi above 3000rpm, and 15 or so at idle with hot engine. So had lifters (valve lash adjusters)remanufactured by http://www.mizpahprecision.com/, installed reman lifters, and same noise. Did not replace oil pump, saw no damage, and did not measure. However, pressure is good at gauge. What sucks-no clatter before tear down. Did I mess something up?
If this thing did not run so good (minus clatter) I'd junk it. Any thoughts?
Thanks.
