Engine has knock on start up when cold ,if restarted within two days all is ok leave three days knock is back sounds like a big end but only knocks on start up all ok when running and high or low revs I have had new timing chains fitted as this was suggested as the fault can you help

I usually found that timing chains caused more of a rattle than a knock . Symptons you describe in my opinion would be more oil pump related .It would be interesting to check oil pressure on start up after 3 days with master gauge .But I am no expert on the Boxster .
