10W-40, The motor has done maybe 2000k of road use, and only about 12 laps at Wakefield 3 sessions of 4 laps super spints and 6 laps of Eastern Creek (but in the wet), so not even getting hot, catch can is being redesigned as more of a oil air seperator style of thing and restricors are being changed to a 1 mm at the rear (whats in there now) and blocking the middle one (has a 1mm in here), the VCT drain is being reconnected and the drains are being rerouted to the left hand side of the sump(VCT has a 1mm restrictor).
Hopefully that fixes the problem, if the lifters get noisey the spring will go back in the Tomei pump to give it some more oil as it was removed to try and stop the oil surge before but that was unsuccessfull.
Goes in again tomorrow for the next week or so.
So with a new TO4Z, recoed gear box, new clutch and the oil under control I may be able to get some fun hot laps in with the new motor, finally.
Hopefully.
