I recently bought a 2003 Range Rover that has a really bad oil leak from the passenger side valve cover. I currently replacing the valve cover gaskets but having some trouble. I can not for the life of me get the rear of the seal seated properly. Are there any tricks that have been used. It’s a bmw 4.4 v8. I have removed the wiring harness out of the way as well as the fuel lines. Any hel is greatly appreciated
