Owner Narrative

Cam tower leaks oil on the heat shield below it. Cam tower uses rtv rubber seal instead of a gasket. The rubber deteriorates and the cam tower leaks engine oil on the heat shield. Not clear why Toyota used form in place rubber material instead of real gasket. Repair however is major. Need to take apart engine to repair. Major repair. The fix is to replace it with the same material again. Which is subject to deteriorate again. This is a know issue on the 5.7 L engine. Toyota seems to have its head in the sand hoping they shouldn’t be forced to recall. However this is a know design flaw resulting in leaking oil on the heat shield. With no Toyota recommended new design or parts repair except to do it all over again and hope it doesn’t leak again it’s ridiculous. . Terrible design that leaks oil on the heat shield.
