Thanks for everyones help connecting the green plugs disconnecting suction advance and blocking hose . Resulting in able to set timing correctly so belts must be ok . new oil new filter plus oil flush additive resulted in smother idle . Ran engine 1hr including 20 minute drive .big difference . Drained oil , new oil , new filter plus a hydraulic lifter additive nice quiet engine but cannot get idle below 1000 to 1200rpm . Also built in turbo bov now working ,wasn't before flush out . 2nd hand engine must of been on self a fair while and oil lines full off goo
I'm in Australia not U.S.A. but hay guys thanks not sure what your additives are but I used Wynn's and in this case it worked to a treat .
Re leaking oil pan gasket ,the secrete is the old standby new bolts with star washer locknuts clean surface's with white spirits or similar then use loctite 587 gasket goo --- six mil -3/16 inch beed on sump leave stand 1 hr then smear engine pan with film of 587 and fit pan tighten to contact only leave 24hrs AND THEN tighten bolts in a opposite diagonal sequence . Works on bent eights and straight six and fours every time .
Yeah the subbie bug is contagious and interesting even to an old fart like me (my son's terminology)
