My daily driver is an 88 300E. It has 210,000 miles on it. I have looked back in the records and have seen no mention of engine work. It does leak a little oil from the front upper timing cover, but I can correct that easily. I did valve guide seals on it and it uses little oil. Good, strong, reliable. I think they are good.

As with all engines, they do wear and have to be serviced. Bearings in the front such as the idlers and the water pump will wear, when this happens it costs money. Sorry.

Thanks
