- How to replace Mercedes OM648 pencil glow plugs on these cars -- in US, 2005-2006 E320 CDI. Also applicable to similar Mercedes and Sprinter engines
Do this job every 50-60K miles, use Anti-seize, torque to 19 Nm, and you will never have a problem.
If yours have not been removed for over 100K miles, think about bringing to a shop -- they can break off and this is essentially unrecoverable for a do it yourselfer -- would require a special kit or removal of entire cylinder head.
This is why it's so important to do it regularly and according to specs as shown in this video - Auta a dopravní prostředky
Very good video. Just changed all six on my 2006 E320 CDI. No issues. The torque wrench method to remove is a Great tip. Spray penetrating fluid in all the holes and let it sit a few days or so. Drive the car as normal with many heat and cold cycles and it will make removal a lot easier. Take your time and things will work fine.
You gave me the confidence to try this on my own. It went without a hitch...#4 was the only real challenging one. All six came out very smoothly and I used a nice ceramic paste for the new ones.
Finally some meaningful work performed 👍😁
Looking forward to the Black Death video just purchased an 05 135k your videos are very helpful
How did you get to #4? A u-joint on an extension?
Could you please post the Hazet catalog
number or specs for the reamer?
thx
Could you please post the Beru glow plug catalog number
A Star diagnosis scanner has a tool that can illustrate actual values in real-time of injector performance & injected quantity corrections occurring electronically if engine's acceleration under load doesn't sound as smooth & uniform as it should & a leak-back test using clear aquarium tubing on return lines of injectors can determine how well injectors are performing mechanically which is the gold standard really short of sending them all to Bosch to be bench tested. At 280k miles, a leak back test might provide insight as to why #2 & #3 injectors are ablating their copper seals & starting to leak compression. I was amazed to find out just how much pressure those seals are under, equivalent to what one might expect to find at bottom of Mariana Trench (...25k PSI)! Glow plugs hold back similar pressures & though I haven't seen this happen on a Mercedes, I've seen pictures of Ford glow plugs that have actually launched out through valve covers & impaled like blow darts into engine hood.
I'd love to do that. Lacking for resources. No Star diagnostic equipment at my disposal. May do a leakdown test, though. I'd suspect that at least a few of my injectors are out of range by this point -- 14 years and 280K on the clock -- but at $500 each x 6, that's the value of the car. My plan is to reseal -- maybe leakdown test -- then let it ride.
Would love to have access to those expensive and professional tools, but I'm just a guy driving a 14 year old car with 280K miles while working alone in my garage. I'm sure the injectors would benefit from rebuild -- but as long as car running smoothly and reliably, will defer
Doc, I got diagnosed with RBBB by an ER doctor. Anything to worry about?
Funny. I just do engines on this channel. Civilian mode.
Please can you give me a list of the tools you used to accomplish this task.
Where did you purchase the reaming tool?
Great question, as I need to do this to mine and need that tool
Great question. But please give us the HAZET part number for your glow plug reamer.
Us: Questions…
Doc: You do not ask question. I make video. Every question is answer in video. Now, back to finger bang #6 plug hole and reaming!
Me: Not to question doc, but I’m wondering about 6 glow plugs in a 5 cylinder engine, respectfully mr doc sir
Hi, what kind past u are using ? Aluminium or ceramic ? Regards
