Hi Mate, this is a great video, I just noticed you didn't bleed the engine, I thought some air might get in - can I confirm that you didn't need to bleed ? Cheers !
Hi Damien. Thanks! There shouldn't be a need to bleed the engine when doing an oil change. However, when changing the coolant, you usually need to. On the OM636, there is a tiny little hose at the fresh water pump that is meant to bleed it, but it is notorious for getting clogged as I quickly found out when I did a coolant change! The way around that is to loosen off a bolt at the top of the water pump to release the air that gets trapped up there and forms a airlock. Thanks for watching!
Great video. Eventually plucked up the courage to do my own oil change as mechanics in my area are as rare as hens teeth. Any advice on the separate spin-off oil filter that Westfield sell as an aftermarket fit? I have a W33 so access is dismal.
I've not looked into the spin-off kit, but could certainly be a good option. I like the reusable filter fitted on my boat, but I do need to get a spare! I'm very careful with it, but nervous on what would happen if I accidently dropped it! If you go for the spin-off route, I'd be keen to hear how it goes! Thanks for watching!
Hi Ray. I was going to include that in the video in fact, but still felt unsure about that seemingly mysterious subject, so did not want to inadvertently share bad information if I'm not doing correctly ! I did refresh the oil in the injector pump by using a syringe to extract the old oil (which looked very clean) from where the the dipstick goes, and then replaced it with fresh oil also using the syringe. I think I got about 150 ml of oil out. It is strange the lack of clear instructions out there on that subject! The Westfield 4X4 facebook page has some info on this. Later next week, I'll make a little video about the injector pump oil and post it on my facebook page here: facebook.com/sailingseadreamofclyde Hope this helps.
@@SailingSeaDreamofClyde as far as I know (I've got a W33 + OM636) the oil in the injection pump is considered a consumable so you only need to check levels and add some if it's low. Never heard of anyone changing it before :D Not sure where I got it from, it may have been from Manfred (runs westfield 4x4) but I'm not sure. Also, look after that TDZ pump, it's impossible to get any spares for that thing and changing it to a Bosch is a happy fun time (not) process (going through it now).
@@BenvanStaveren Hi Ben. Thanks for that info! I decided to extract what I could as when I pulled a little out, it seemed as tough it was very thin and resembled diesel rather than oil. Had you found that with yours? Maybe it was just warm oil that appeared thin, but was fine... not sure, but either way, after exchanging the oil that was there with fresh, everything was running well. Here is one of the bits of info I found: forums.ybw.com/index.php?threads/mercedes-benz-om636-with-tdz-injector-pump.366706/ Had you just always added oil, but never extracted it to refresh it?
@@SailingSeaDreamofClyde as far as I know, the oil will mix with diesel in the pump so it will come out looking very thin - I generally just check it before I depart, if I think it looks too thin I add a few squirts from the oil can. Can't over-fill it anyway, if it's too full the pump will just start dribbling it out of an overflow hole. Also just read the link you posted, which pretty much says what I just typed. Might even be where I got the info from.
@@SailingSeaDreamofClyde oops, too quick on the enter key - I've never removed the oil before, just added when I thought it looked like it needed it. I can no longer really speak as to the TDZ pump since mine busted it's little guts last season, so I'm now in the fun process of installing (and timing) a rebuilt Bosch pump. Same idea, though.
Thanks John! Westfield 4x4 in the UK is my go to. Very prompt shipping, and owner Manfred is very knowledgeable. He strictly deals with the OM636, including rebuilding. I take it you have a OM 636? Cheers!

I'm kind of jealous with the level of access you get in a Discus. In the W33 I get front and top access relatively easy, but no way to get at the oil filter without making like a snake person in the engine room. Unless I carve out an access panel under the galley sink where all the drawers are (so still a pain in the ass to get to regardless).
Yes, the engine access is pretty nice on bridge deck version of this Discus. After some pretty brutal engine access on my last boat (a "Cal-29"), that was one of the selling points for me when I first viewed Sea Dream of Clyde! The oil filter is accessed from under the galley sink for me, too. But I don't need to remove the drawers above, but just a few cooking pots I store in there. Thanks for your input above! It is reassuring for me to hear your experiences with the TDZ pump, and I'm sure will be helpful for others that come across this.
@@SailingSeaDreamofClyde no problem - I hope it'll help a few people maybe. Can't beat the OM636 for reliability, they're worth looking after. It's maybe a little ridiculous to have 42hp on a 33ft boat but eh, better too much horses than not enough :D Wildlings Sailing recently did a series of videos on a 636 rebuild, also interesting to take a look at maybe :)
@@BenvanStaveren Ya, for sure, though where I cruise, the extra HP has been helpful to get through some of the many strong tidal passages around here when I've been late or early for slack current! Ya, I saw those rebuild videos. Great series indeed!
SAE 30 is good for the High Pressure injectorpump.

Thx was allot of help!
My pleasure!
Thx! My filter looks a bit different. One long bolt in the middle of the filter but also washable. 😊
Hi have u ever changed the injector pump oil, any info u have would greatly appreciated Thanks Ray

Where do you get parts for your Mercedes diesel engine?
Cheers
Yukon John!

Ya, I saw those rebuild videos. Great series indeed!
On my Discus I made an access hole on the port side. This for easy access to the raw water pump.(seawaterpump)
But after watching the vid again, I noticed Sea Dream of Clyde has that already. Good.
