Hello ! Let me explain: engine is a modded Toyota 3SGTE ( 2000cc turbo - 425 4whp ) It's 1000 miles old... the running in, a map session, and a track session... only 6 laps because I cracked a weld in the ext wg feed pipe. In those 6 laps oil reached 120 deg C., not more, but oil pressure wasn't so high... 1 bar at idle AND 2.5 bar at 4000 rpm. That's why I put off the stock oil pump, and bought the $$$ WRC-TTE oil pump... ( and even because my oil squirters are TTE - open at 3.7 bar ). When changing the oil pump, I also checked the valves' clearance.. BUT I looked at the camshafts and it seems to me that they were worst that they should be... Imagine a new camshaft...with its shiny pins... now, after 1000 miles, pins have some darker zones, yet shiny, but darker. the pins are not deeply digged as if some dirt passed with oil... at the most they seem like they were nearly to seize ! Poor oil pressure ? Or too little oil clearance ? What oil clearance do you use in your engines ? FYI camshaft journal diameter is 26.97mm ( 1.0618" ) TIA. Bye...
