Well, I finally got the head off my 300E. After blowing the head gasket about two months ago. I removed the plugs and turned it over. It appeared that there was a little water in the back two cylinders. The dipstick looked okay, no hint of water in the oil. I squirted oil in the back two cylinders and hoped that it would wait on me.

When I drained the oil yesterday, there was a lot of water in the bottom that came out before the oil.

When I got the head off, the front four cylinders were badly rusted.

Because of everything going on and my travel schedule, the car sat for a long time. I am really bothered to see this rust. I cleaned it up as best I could, turned the engine, oiled the cylinders, cleaned some more, oiled again, and so on. I got the cylinders pretty clean and left a good coat of oil on them and then covered them with rags.

Since the engine has not run with the rust on the cylinders, do you think, I am going to get by with this? My thinking is that when I put it back together I will run it to operating temperature, then drain the oil and change the filter, then maybe run it a few hundred miles before changing oil and filter again.

Any thoughts or bets?

Thanks to everyone,

YOU will be fine. I saw a tech do this at the shop one time. He took off the head and it sat for 6 months. When he reinstalled the head, Hans just oiled the cylinders and all was OK.

Good luck

It will work fine. The rust won't hurt anything, as little as you say is left. I have seen cylinders horribly scored and rusted slapped back together and still hold good compression.

I am fully recovered and back on the line at the shop. I set a shop record last week of 170 hours turned for a two week pay period. (Yes, I worked my a-- off to do it, but I wanted to prove a point to the old guys.) Not all of them thought I could do it after having a desk job for a year or so.

See ya/
