Hi.
I rebuilt my engine some 1000 miles ago, the rebuilt included new piston rings and big end bearings. Also did the valve stem oil seals etc. The car has a pace alloy intercooler, ahmbed bayjou 195bhp chip and mahle low comp pistons, but if you run 0.9 or above bar of boost, the oil filler cap pops off which means the car stalls when not revving the car
I have one of those oil filler caps with a crup screw and large oil ring on it etc, so am going to try and fit it. Is there another way round this or has anyone had experience with this happening on modded engines? Also, when running higher boost you can smell a kind of petrol/burning oil smell from the dump valve.....?!?!?!
Thanks, Paul
