Good 602 pics. Why didn't he run the rtv gasket material around the bolt holes too?

The $12 set of 8-, 10-, and 12mm triple square/double hex bits at Autozone are all I need. If the bit breaks within the return period, they'll replace it. Using this cheap tool means you have to pull the cam. A longer bit lets you remove head bolts covered by the cam towers without removing the cam towers but you have to handle the head with head bolt tips exposed and valves in the open position. I'm too clumsy to trust myself with that so I'd pull the cam even if I had the longer bit. Don't foget the smaller bolts in the timing chain cavity and the one by the fuel filter.

Bob, thanks for the site addresses. I got great information from them that is helping. I have everything off except the exhaust and head bolts. Will not be able to work on it again for a few days, but am beginning to see some light at the end of the tunnel. I also discovered from the site that he had exhaust bolt 1 broken. Mine has done the same thing. I hope I will be able to extract it as he did. Again, I really appreciate all the input on this board. Hopefully I will be a proud mercedes driver enjoying the great diesel experience.

Got her apart yesterday. Head gasket was definitely blown on #1. It had a gap in it that was about 1/8 in. No wonder it was pouring oil out the exhaust pipe. Everything else looked great. Head and block were in great shape. In the process of putting her back together. So far so good. Now if I can remember where all them bolts go. I don't know how many parts you are supposed to have left over on there cars. On American cars usually 2 to 5. Makes cars lighter and perform better. HA!! Anyway, I have to get back to her if I am going to hear that beautiful diesel sound in the near future.

Got her done. Started this afternoon and performs perfectly. Love the diesel sound of power and economy.
Thanks to this site I was able to get the information I needed to correctly diagnose the problem and get it fixed. Thanks so much to everyone who contributed to solving my problem. Now I am smilin

Exclamation Use Quality tools

So far it has ended well. I only had one surprise. I borrowed a cheap set of serrated sockets to fit the head bolts. Like another poster on here mine broke on one of the head bolts. Fortunately for me I was able to remove the broken piece with a magnet and was back in business. I went to NAPA and bought a good one that finished the job for me. Learning that it pays to use good tools, especially on critical areas such as the engine.

Up and Running

Got everything in place and began driving her yesterday. Everything went well except she smoked for awhile burning all the excess oil out of the exhaust system. Since I just bought the car I began to check everything out to make sure all was well. Only 2 problems so far. Odometer quit working. Strange since it was working when I first drove it. Needs freon in air conditioning system. I have already purchased Freeze 12 on ebay and am prepared to fix that problem. Everything else is as it should be. Really nice driving car. This is my first mercedes diesel and I am looking forward to enjoying some quality time in it.
Since the speedometer works but the odometer quit I am thinking the problem is inside the housing. I do not know of anything I could have done to cause the problem under the hood but will check today. Any input appreciated.

Was this the first time you worked on a MB diesel? R&R the head is quite the "first project" on it.

That was me. It took me MONTHS to find time to slowly grind away at that bolt head and get the head off... I just got it done Sunday. Mine had the same issue you found -- blown gasket at the oil passage up front. Obviously this is an issue for the 602's! I need to check my head bolts and whatnot, and order my parts now. Glad to hear your R&R went smoothly!

First time I have done head gasket on MB Diesel, but not first time I have done head gaskets. I used to own 2 escort diesels, and had to replace head gaskets on them at least twice each. They lasted about 75000 miles each and gave out. I had the heads resurfaced and that stopped the problem for blown gaskets on them. They were bad about warping.

The information on this site was a great help to me. The insights you gave me helped me avoid mistakes that I could have made if I had not been here.
I did my first head job on my 57 chevy when I was 18. I am now 61, so you can see that I have been at it for awhile. It is just a hobby that I enjoy.

The mercedes really drives great. Only 2 problems I have found so far. Cruise is erratic and kicks out and odometer is not working. Hopefully I will get these corrected soon.

cscmc1. I got my head gasket set on ebay for 47.99. It was Elring, which my dealer said was better of those available. Seller is cedric9371. He has great prices and free shipping. Got mine in 5 days from California to Ohio. MB dealer prices same thing to me for $129.00 with discount. You may check out ebay for saving money on these things.
I have a 2000 Saab that had bad abs computer. Saab wanted $2950 to repair. I found gentleman on ebay who rebuilt mine for $225. He made money and I save money, LOTS.
Good luck on getting yours back together.

Update

I have been driving this Jewel every day since repair completed. Love the way it handles and performs. It is my first mercedes and I didn't really know what to expect. It drives and rides well. Has a great feel to it, much better than I expected.

Odometer has quit working. I reset it when I fueled up and it has not worked since. I saw a thread on them and hope to fix when time permits.

Now in the process of repainting it. Planning on keeping it for awhile and enjoying the dirve of a mercedes.
