Piston geometry and modifications are in the FSM:

Not completely clear if the .97x deleted just the angular channel and retained the sprayer nozzle or if it all went away. Considering how Mercedes says that the angular channel is designed to help with thermal loading, it seems strange to delete it from the larger engine...

What is wrong with the 87 300SD? You're willing to buy an entire car, pay the registration/safety on a vehicle that you don't know the maintenance history and such, could could possibly have an engine that will go bad? Even if you got the car for $5000, could that money not goto OEM parts/labor on the 300SD?

What is wrong with the SD and what needs to be fixed suspension wise? Also there's nothing wrong with having a shop do some work for you. A lot of the major work I have done, I pay shop labour and I'm happy to do so in some cases.

I'd not want to pay 8K for a 350SDL. I had one for a year or so and enjoyed driving it, lots of nice torque and a sweet transmission and interior. I ultimately feared the rod bending I believe.

OTOH if you look in the classified I have my daughter's very lovely 85 300SD for sale with new leather on the front seats, a freshened motor and a lovely new paint job over a southern rust free body for $4,000. This car is good enough I sold it to my youngest daughter.

Mercedes just made a bad choice by boring out the block basically. If you look at the small amount of material left between the bores. In comparison to the 3 liter. It is pretty obvious.

This alone should give people pause. This had to substantially weaken the block. North American dealers wanted a stronger diesel engine is the story. True or not this was their answer.

You have to accept that German cars just require more service. If you are content with this that is fine.

I like the 1985 and older models as I can cope with their needs easier. They may also be more reliable in general as well.

My reading of that pdf is that they changed the piston design slightly by deleting the annular channel, but it clearly states that the piston crown is still supplied with oil (from the oil nozzle jets) and a recess is included on the piston skirt for the oil nozzle.

I agree, the bore made the block too flexible in my opinion and caused sealing problems with the head gasket, and eventually would lead to a partial hydro-lock making a slightly bent rod which then would wallow out the cylinder bore and cause poor sealing.

Any owner on the thread who can share their opinion of the 2005-2006 E320 cdi?

I am on my third W211 Diesel, and can honestly say from experience that they are great cars. Being a DIY guy, the '07 Bluetec is right at the edge (but still on my side) of being out of my ability to work on. The '05-'06 CDI are very DIY friendly. Both CDI's that I have owned needed only basic maintenance for the years I owned them, with the only exception being my latest one needed the SBC module rebuilt. It still was not that big of a deal, and only cost about $700 total. I sold my first CDI to my niece, and she loves it. My second CDI I sold to her mother, and she is now enjoying it. The '07 I drive now has been extremely reliable. As far as repairs, the oil cooler seals needed replacing, and then the swirl flap motor was replaced a couple months later. Both these jobs I did myself, and weren't that bad (actually kinda fun!). I really enjoy the comfort, safety, and overall feeling of the W211 platform. I will say that the natural progression from a W126 is to a W210 ('98-'99 E300). These are becoming very affordable. My opinion is that they are the last of the "best" Diesel cars made, and probably the most bang for your buck. Yes they have their problems, but they can be the most reliable and inexpensive cars to maintain, and with more safety features than the W126.

Not so for the '07 W211. I have changed the air filters twice on mine (once for previous owners, and once for me), changed the oil three times, transmission fluid, fuel filters, oil cooler seals, swirl flap motor, and turbo positioner on my Bluetec. No dealer visit needed. Yes I do have an Icarsoft MB II scanner, but that was only $160 on ebay. A small price to pay for what it does. Yes of course a dealer is needed if the owner is not a DIYer, but basic maintenance items (and even more complex) can all be DIY.

I just spent my morning ripping the exhaust manifold, cross over pipe, downpipe and a whole bunch of other things from a w140 om603 in the JY to install in my 87. Having crawled all over that car, the w140 is an overweight cluster****. They got the head and the exhaust manifold right. Everything else is garbage. Also the w140/om603 is down 15hp vs the 87 despite the extra 500cc. I think they did that for emissions because it doesn't have any kind of exhaust after treatment.

This will go well with my #17 head.

There's an #18 ripe for the taking in the Windsor PnP

did the car still have the power steering pump and air cleaner box?

Pump yes, air clean box lid was off, filter and lower box we're still there. I think the lid was on the ground.

If you are going back and feel inclined, I really need the power steering pump and air box if you would be willing to ship it. If not, I understand. I am having a hard time finding these.

Sorry it's not near where I live. I was just passing through. I figured somebody might put the #18 head to good use.
