Hello, I am new to this forum and more than likely this problem has been posted previously, but I could not fine it. I have a 1992 Landcruiser 4.0 liter. The small .250" diameter aluminum plug on the right side of the head, (located towards the rear of the head right in front and above #5 spark plug) came out and subsequently I lost near all the engine oil. I replaced the plug and it is still leaking badly from around the plug. I removed the valve cover and it seems the plug does not vent to to this area. Can someone tell me the purpose of this plug and how I can properly seal the oil leak. I am going to need to remove the plug I just put in and try again. The Landcruiser has only 100K miles on it and runs very well and uses no oil, so I would rather not remove the head to fix this leak. Any assistance on this problem is appreciated; or simply direction on where to go to find the proper solution. Thank you.
