hi guyz...
M.W.P. : no smoke (startup or off-throttle). Try the URL in the sig - it's the current site for the car - i've been pretty slack updating it - too busy building megasquirt, dissasembling a RA40 with a 1G-GTE and family stuff.
My older RA23 used to have a cam chain rattle - once it got up some oil pressure, the tensioners started to work and rattle went away. Yors sounds familiar.
I never got hardened valve seats/stems when i got the motor rebuilt - i figured that by the time they wore out, the rest of the motor would be in need of care also.
THE WITZL: I'm think the valves were only cleaned up and re-faced when the engine was rebuilt, but new guides were put it - so as long as the rebuilder (swift engines @ rocklea) used toyota valves and valve guides, running mostly UL (BP's 98RON premium UL being the preferred) isn't going to lead to premature valve wear? well, not within ~20,000K of rebuild.
so (gulp) i hope it's not something more dramatic... oh well...
