pgrbff Posted February 12, 2014 Share Posted February 12, 2014 New to Defender (1995 300Tdi) and diesel. I replaced my diesel filter today (amongst other things) and expected to have to bleed the system to get her going again. I undid the bleed screw on the filter housing and pumped the primer lever with ignition off and then on to prime her but never saw any diesel at the bleed valve. There was little or no resistance at the priming lever. She started nevertheless and apart from the revs changing occasionally till she settled down she ran just fine. Why didn't I see any diesel at the bleed valve? Also, (blue box) filter had two washers, one copper and the other what appeared plated steel. What were they for?

mmgemini Posted February 12, 2014 Share Posted February 12, 2014 You don't need to bleed a 300Tdi it has a self purge system. What I normally do is change the engine oil and filter. After checking there's no oil leaks by running the engine, then I change the fuel filter.and start the engine again. As you've found it runs rough a bit then clears.

pgrbff Posted February 12, 2014 Author Share Posted February 12, 2014 Thanks. I'd been told it would need bleeding. Still like to know why there was no diesel at the bleed valve? Quote Link to comment Share on other sites More sharing options...
mmgemini Posted February 12, 2014 Share Posted February 12, 2014 Maybe the cam was holding the pump off so there was no pressure Quote Link to comment Share on other sites More sharing options...
pgrbff Posted February 13, 2014 Author Share Posted February 13, 2014 Any ideas on the two washers included with the fuel filter? The copper one looked like an engine sump plug washer. Quote Link to comment Share on other sites More sharing options...
Reiny Posted February 13, 2014 Share Posted February 13, 2014 Don't worry about it. Just fire her up and she'll self bleed as mmgemini said. Just avoid revving it for a minute or two. Quote Link to comment Share on other sites More sharing options...
pgrbff Posted February 13, 2014 Author Share Posted February 13, 2014 She was fine. But I'd still like to know what the washers were for. Save me buying something I already have! Paul Quote Link to comment Share on other sites More sharing options...
Reiny Posted February 13, 2014 Share Posted February 13, 2014 Not aware of any washers that require changing to be quite honest with you. Keep them. You'll never know when they might come in handy. Quote Link to comment Share on other sites More sharing options...
mmgemini Posted February 13, 2014 Share Posted February 13, 2014 Nail on garage wall. Hang washers on nail. Then when you need a washer, you've forgotten all about them and you go out to buy new Quote Link to comment Share on other sites More sharing options...
pgrbff Posted February 13, 2014 Author Share Posted February 13, 2014 When you have to wait 10 days and pay £10 for a parcel to arrive from UK yo want to know what it's for. Quote Link to comment Share on other sites More sharing options...
dailysleaze Posted February 13, 2014 Share Posted February 13, 2014 They're probably included to replace the washers on the banjo if it's removed to bleed (even though bleeding is not required). Quote Link to comment Share on other sites More sharing options...
pgrbff Posted February 13, 2014 Author Share Posted February 13, 2014 No idea. I bought two filters, and I found another non copper one in the bottom of the box. I'll check the second filter box tomorrow. Quote Link to comment Share on other sites More sharing options...
