Oil pressure check
Whenassemblyoperationsarecompletedllenginewithoilandfuel;
connecta10barpressuregaugetotheoilltertting.
Starttheengineandcheckpressureasafunctionoftheoiltempera-

Calibrated pipe for lubrication of hydraulic tappets
The pipe is tted to the hydraulic tappets oil line (see g. 83, detail
11).
If the calibrated hole is clogged, the tappets are not sufciently
lubricated,valveclearanceisthereforeincreasedandtheenginemay
benoisier.
Ifthediameterofthecalibratedpipe islargerthantheones givenin
picture93,thepressureexertedby the hydraulic tappetsmaycause
thevalvestoremainopenevenduringthecompressionphase.
