Hello. After solving a few oil leaks on my 98 300 tdi. I found it still was dripping oil. Well i looked at the vacuum pump thinking it could be that. then i spotted it leaking from a rubber plug. there's three holes and i can only think the other two have come out on there own accord. end one near flywheel end has no oil round it the one at the back of the vacuum pump has some oil round it and the one above the lift pump had one in it but oil was coming from around it. I took it out to find I could see the cam through the hole. the plug is around 1" long. Can anyone tell me what they are called and What they do. Apart from stopping oil coming out. It seems to me that the oil pressure hasn't reached the end cam bearing cos the pressure wasn't there to feed it Because the pressure was lost with the leak. If no one knows what they are can some one check there 300 tdi see if it has these rubber plugs there small but visible from right side of engine. Cheers everyone.
