discojmz Posted October 14, 2008 Share Posted October 14, 2008 on this photo, to the right of the oil seperator is a boss for a hose. ive seen this on a few 200tdis on ebay in the past but never been able to ascertain where on earth it goes to and what it does... point being, mine does not have one. the casting on my rocker cover is completely flat at that point. If anyone could tell me whether or not I should have one or am at a disadvantage without, id be most grateful. Im assuming breather. In fact on further investigation on microcat it seems to be a breather pipe that runs down to where one of the side covers is on the block (forward most one) but again, no clue why I wouldnt have this! thanks Quote Link to comment Share on other sites More sharing options...
Guest WALFY Posted October 14, 2008 Share Posted October 14, 2008 There isn't 1 on my 200TDI. So it's not that vital Quote Link to comment Share on other sites More sharing options...
discojmz Posted October 14, 2008 Author Share Posted October 14, 2008 that'll do for me. thanks Mark! it's still aroused my curiosity why some do and some dont. Maybe its just one of those great mysteries of the universe that we're not supposed to know ...bet Ralph and Jamie know Quote Link to comment Share on other sites More sharing options...
Guest WALFY Posted October 14, 2008 Share Posted October 14, 2008 There's only oil vapour mist that high up or it could be someones bodge for some form of overpressure from the engine Quote Link to comment Share on other sites More sharing options...
Les Henson Posted October 14, 2008 Share Posted October 14, 2008 That pipe stub connects to a rubber hose that goes down the side of the block on the drivers side to a baffle plate. 300TDi is the same. Les. Quote Link to comment Share on other sites More sharing options...
Guest WALFY Posted October 14, 2008 Share Posted October 14, 2008 Mmmmmmmmm. I'll have to have a look now. I only had it all apart not that long ago and could of sworn that there wasn't anything there. Hence my reply. Will have to go check now Quote Link to comment Share on other sites More sharing options...

bush doctor Posted October 14, 2008 Share Posted October 14, 2008 My Defender hasn't got one am I also at a disadvantage. It's a 1994 so is out of warranty should I contact Solihull to see if it was a recall Quote Link to comment Share on other sites More sharing options...
JimAttrill Posted October 14, 2008 Share Posted October 14, 2008 All 300Tdi's have a hose there without exception. In your engine, is the hole in the rocker cover blanked or what? And the lower hole also? Quote Link to comment Share on other sites More sharing options...

Les Henson Posted October 14, 2008 Share Posted October 14, 2008 EPC shows the pipe there for both Disco and Defender 200TDi's. I would imagine that if the pipe is blanked off on the rocker cover, then there would be just a flat plate where the baffle usually is - same as N/A and TD engines. It would mean that some engines have two breathers - rocker cover to rear of block (near camshaft), and then rocker cover to front of block. There's a familiar problem with oil leaking out of the oil seperator - partly due to a single bolt holding the thing on. Perhaps early engines had no second breather pipes, but later ones did? Les.

discojmz Posted October 14, 2008 Author Share Posted October 14, 2008 mine's one of the very latest 200tdi's and does not have it. it doesnt have the stub blocked off, the stub is not there full stop, the rocker has no sign of ever being cast with one. as said, theres a flat plate on the side of the block Quote Link to comment Share on other sites More sharing options...
JonR Posted October 14, 2008 Share Posted October 14, 2008 My parts catalogue says: ERR1530 Rocker cover Up to April '92 ERR3368 Rocker cover From April "92 So if Jims was one of the last 200Tdis and doesn't have one then it looks like it was deleted from april "92.

Perhaps early engines had no second breather pipes, but later ones did?Les. the breather leaks because the o'ring has got tiered. Pull it off replace the o'ring with a new oil resistant one. then I also so put a little silicone one for good measure Quote Link to comment Share on other sites More sharing options...

Guest WALFY Posted October 15, 2008 Share Posted October 15, 2008 There isn't 1 on my 200TDI. So it's not that vital I stand corrected. I do have tht pipe . In all the times that I've stripped it all down I've never consciuosly noticed that pipe . Sorry for the missinformation. I will now go and chastize myself Quote Link to comment Share on other sites More sharing options...
western Posted October 15, 2008 Share Posted October 15, 2008 my 200tdi doesn't have that pipe, just a blanked [undrilled/machined] part of the rocker cover. Quote Link to comment Share on other sites More sharing options...
draper40 Posted October 15, 2008 Share Posted October 15, 2008 My defender 200tdi doesn't have that, but the disco one in my garage does! Pete Quote Link to comment Share on other sites More sharing options...
JonR Posted October 15, 2008 Share Posted October 15, 2008 So, the question is, what specifically is its purpose and was it really effective at doing it, why was it deleted (cost saving/didn't work) and why was it reintroduced on the 300Tdi..... and...... if I haven't got one do I really need one ??

Les Henson Posted October 15, 2008 Share Posted October 15, 2008 I looked at 2 x 200TDi Disco's today and both of them had the pipe. I don't ever recall seeing one without the pipe, but they obviously exist. I don't know if one is better than the other though. It does seem odd that these pipes were stopped and then reintroduced again. I wonder if Land Rover realised their mistake. Les. Quote Link to comment Share on other sites More sharing options...
western Posted October 15, 2008 Share Posted October 15, 2008 probably deleted as it wasn't a great effect on the crankcase vapours passing oil mist back to the sump, seems maybe the cyclonic breather was more effiecent. Quote Link to comment Share on other sites More sharing options...
rusty_wingnut Posted October 16, 2008 Share Posted October 16, 2008 my guess is that its used to equalise the pressures either side of the seperator. helping the seperator work more efficiently? Quote Link to comment Share on other sites More sharing options...
discojmz Posted October 16, 2008 Author Share Posted October 16, 2008 i wondered if it wasnt required on the 200tdi so it was removed to save money and leaks. it was replaced on the 300tdi as part of the meeting emissions regs process Quote Link to comment Share on other sites More sharing options...
tomaco1 Posted May 1, 2017 Share Posted May 1, 2017 (edited) Revived thread I have the option to go in either direction with this, breather or no breather. Breather is already installed on my rebuilt motor, but I have the blanking plate and blanked valve cover if that's the better way to go. Does it really matter one way or another? Thanks Edited May 1, 2017 by tomaco1 Quote Link to comment Share on other sites More sharing options...
