Hello All,

'87 300SDL 202k

Last week she started to idle a little rough and got progressively worse. I thought it may be the injectors so I put in a rebuilt set and fired her up (I pop tested them and all were around 2000 PSI). NO CHANGE

So, I started her up and cracked open each injector line - the engine ran differently the second I turned the nuts on injectors 1 through 4. Injectors 5 and 6 made no difference. Fuel did leak out of 5 and 6.

I have only had the car a few months. It does not smoke and the engine temp has been stable in the 80-90 range.

More information if this helps. The previous owner said he had the delivery valve seals changed and new nozzles installed. The power level has never been what it should be - 16 second 0-60, but the car otherwise ran well and I thought I would take care of that after I got the heat/AC stuff done. Looks like the diesel gods have decided otherwise....

What do I check now?

Thanks!

Richard
