Yep, the owner just called MB with his VIN and found out that the replacement hasn't been completed, so he's scheduling a visit. I'm about 90% certain that thing is clogged. The thing is that I just got done removing all the emissions crapola, so now I have to re-install so that the dealer doesn't balk during the recall work...grrrr

The VCV on this one won't pass more than a little vacuum on through to the outlet port, no matter how I adjust it--it's blocked nearly completely.

[QUOTE=auspumpen;2954304]Has anyone here actually experienced a clogged trap oxidizer on an '85 Cal-spec OM617? I ask because I'm working on one at the moment, and it just doesn't want to rev quickly and produce much power. I've tested the ALDA (holds 10psi), and cleared the banjo bolt, and bypassed the switchover valve...but, still no dice. Timing is at 15 ATDC, chain is 1 degree stretch. Unlike the OP, this one will rev up to redline, but it just doesn't do it with authority and feels like it's being held back. I also suspect that the intake is all coked up due to the EGR, so that might be contributing.




When we bought our 85 300D, it was experiencing a lack of power. the Indie shop called the dealer and gave them the VIN#. the Trap is suppose to be replaced every 30k miles, and this one was over 50K miles. took it to the dealer, and they replaced the Trap, this was back in 1997.
They did some lousy work, the dang thing fell off one day, and haven`t seen it since.
