11-22-2010, 01:52 AM #1Hi folks, I have a 1986 300E 5 speeder and am looking at options to get diesel under the hood. Having the car is nice, but it needs some body work and has seen better days! So any feed back would be great! Option 1) Install an OM 603 from a US Spec 1987 300D 2) Install a OM606 from a later US 300D 3) Install a Turbo OM602 2.5L from a later W124 4) Install a 603 3L NA from a Euro car. 5) Buy a Nice 1987 300D and use the current car as he Donor 6) Make my wife Happy and sell the 300E 5 speed to someone who will do what I am talking about. Thoughts? BTW I am looking for a nice commuter car and making the A/C work and the like. Thanks!

11-22-2010, 08:19 AM #3The most resonable with price, is find a good body, low rust, good running 300d om603. Use this 300e as a donor for good parts, and for the 5 speed swap.
If you go with George3soccer suggestion I have a 1987 300d light blue ZERO rust New Mexico car no mods other than 8 hole wheels.. need to keep working on my house..has a hitch. I could even bring it to you if SFO is SanFrancisco. I would bring my son and take the train back he would love that.

14, 15 and 16 heads are fine. You only need to be careful about excessive heat and 17+ heads allow more room for error.

It's more than just heat from what I have read. There were poor castings and poor metallurgy, even with normal use and no overheating you can get cracks. Then again there is alot of discourse and very little factual information.

Problem with "driving until it goes boom" is the "boom" could also be the bottom end as well when it hydrolocks.

All 603 have a problem with the gasket sealing between the timing chain and cylinder one, and all straight six with aluminium head have some gasket issues.
Ive never heard about hydrollocking from cracked head on these.
This is my experience from Norway.
My experience, is that the N/A 603 have no problems at all with cracked heads, på the turbo-engines use to get cracks between valve seats and PC`s at 350 to 450 k km.
