Following track day session, on slowing coming off track got low oil pressure light. Gauge showed always had oil pressure but seemed lower than normal for same revs. Once oil cooled had full pressure again. However once oil warned and thinned pressure dropped and again light on at idle. After car sat for day, MAJOR smoke on startup (well byd the small startup puffs you occasionally get). At indy shop that does Porsches in area, pulled sump and found no shrapel, oil pressure relieve valve good, screen clean. Scoped all cylinders and found no noticible grooves or marks or anything out of ordinary? Car made no odd noises, has no leaks but cylinder 5 filling with oil? What should we be looking for next?? Any help of suggestions appreciated
