Hi, further to previous post on sump refitting issues... Cracked sump, removed witg help of Guide on here, repaired at fabricator, refitted by following guide. Took for a test drive and oil pressure gauge went to zero. Pulled over straight away and engine off. Checked oil level and fine, checked for leaks and none visible at that point. Figured it was the gauge so fired up and gauge was showing full pressure and then dropping to almost zero, intermittently. Got the car home, about 5 miles and dropped oil and sump. Think the sealant pattern could be the issue. Tried to follow pattern from when I took sump off, but was hard to see and looks to be gaps. So firstly does anyone have the correct pattern they can share please? Second thing, on the sump plate a heat spot has now appeared. Anyone have an idea of what may cause this? Link to photos. Before and after, to illustrate heat spot. Thank EDIT: to save you reading on, heatspot resolved. Fabricator applied heat when releasing a seized alen bolt
