vulcan bomber Posted August 2, 2012 Share Posted August 2, 2012 IS there somebody on the forum that has a spare and is willing to sell it to me and send it over to Holland? I've got one from a disco that could be altered to fit. Trouble is it'd probably cost more to send it than the cost of the rad. Quote Link to comment Share on other sites More sharing options...

You probably right about that, but i'll kep it in mind if i can't find anything else. Thanks for the offer both of you Quote Link to comment Share on other sites More sharing options...
tukko Posted August 3, 2012 Author Share Posted August 3, 2012 Small question? When I accelerate there is some black cloud coming out of the exhaust. I know that i can reduce them by turning the pump. But wich way should i turn it. Should i turn the top of the pump towards the engine or the other way? Thanks Quote Link to comment Share on other sites More sharing options...
tukko Posted August 3, 2012 Author Share Posted August 3, 2012 By the way the engine is running. Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted August 3, 2012 Share Posted August 3, 2012 Top away from the engine.. Scratch the pump and timing case so you can see ho much you've moved it. Quote Link to comment Share on other sites More sharing options...

Was a bit disapointed today. After a drive on the freeway my oil light went on at idle speed. I wanted to swap de oil pressure switch for another one and then i found out that the internal thread was gone. Maybe that 's way it's losing pressure? Probably not. Tomorrow i will make a new thread and try a new oil switch to see what happens. Quote Link to comment Share on other sites More sharing options...

reb78 Posted August 4, 2012 Share Posted August 4, 2012 Could it be the oil pump? Maybe it's not building up the pressure? Might this just be an issue as the new rings etc bed in? There will be a running in process you should probably observe to get the most out of your rebuild....., essentially, my understanding is don't leave it idling and don't thrash it, but others will have more detail of that or you. Is the idle speed set high enough? Just a thought. Quote Link to comment Share on other sites More sharing options...

Is the idle speed set high enough? Just a thought. Idle speed,is set at 800 rpm. I know it's a bit high but it runs very smooth. It could be the new rings, i don't know how this process is going but it makes sense to me Quote Link to comment Share on other sites More sharing options...
tukko Posted August 4, 2012 Author Share Posted August 4, 2012 The oil pressure is with a cold engine 3 bar. How much should it be with a warm engine? The gauge shows a pressure of 1,2 bar that 's 18 psi at a idle speed of 800 rpm Quote Link to comment Share on other sites More sharing options...
ejparrott Posted August 4, 2012 Share Posted August 4, 2012 Maybe a tad low, but I don't think its much to worry about until you've had a running in period. IIRC my TDi is supposed to be 55 cold and 25 warm, I think Quote Link to comment Share on other sites More sharing options...
tukko Posted August 5, 2012 Author Share Posted August 5, 2012 Can any tell me how i fit a cyclone breather to an 2.5 TD. I know it's done in a later stage on the 2.5 NA defender engines but i can't find anything about it. Regards Roy Quote Link to comment Share on other sites More sharing options...
western Posted August 5, 2012 Share Posted August 5, 2012 you can't, the breather on a TD is in the oil fil cap, the Tdi cyclonic unit attaches to side of rocker cover & drains to the sump. you could fit a oil catch tank & pipe the so drain back to the sump.

tukko Posted August 6, 2012 Author Share Posted August 6, 2012 Here a few pica's of a 2.5NA army diesel with a breather system. Any one seen this before? Quote Link to comment Share on other sites More sharing options...
rusty_wingnut Posted August 7, 2012 Share Posted August 7, 2012 I modified my TD with this sort of arrangement. I had to weld a tube into the sump but it's not hard. Quote Link to comment Share on other sites More sharing options...

reb78 Posted August 7, 2012 Share Posted August 7, 2012 On the later TDs, isnt there an oil feed back to the sump at the back of the rocker cover? You could possibly 'T' a pipe from the bottom of a cyclonic breather into that - the breather would be fed from the oil filler cap and run to the air filter and the drain in its bottom pipe. I reckon it should be easy to modify one from a tdi if you can get hold of one. Quote Link to comment Share on other sites More sharing options...
markyboy Posted August 7, 2012 Share Posted August 7, 2012 Going back a few posts to your issue with oil pressure. Firstly, piston rings have no bearing on the oil pressure. The oil rings "merely" prevent the oil in the cylinders from finding its way into the combustion chamber. Oil pressure problems relate to worn/faulty oil pump or pressure relief valve. Alternatively, if your crank bearings are badly worn this can also cause low oil pressure. 18psi oil pressure on tickover with a hot engine doesn't seem unduly low. HTH Mark.

Yes it's the black hose from the rockercover to the engine were the camshaft sits (see picture) like you said above it should be possible. I asume it's ok for the engine?

Hello Mark, considering that every thing has been replaced, except the oil pump (i forgot) it almost could'nt be anything else then the pump.

RustyNissanPrairie Posted August 7, 2012 Share Posted August 7, 2012 I have the modified set up on my ex-mil 13J engine. The oil return needs to go to the sump under the level of oil - cant quite remember why-its summat to do with the negative pressure of the inlet manifold connection. Works well though.

tukko Posted August 12, 2012 Author Share Posted August 12, 2012 Hi all, after a long drive to a camp site in Gemany i parked the car in front of the office. After everything was arranged i went back to the car to start it up. I noticed that the car had difficulties to start. Although the battery is ok, i was thinking, is it possible that when the new piston rings are warm/hot that it causes so much friction (because they're expanded), on the cilinder walls that it is hard to start?

timppl Posted August 13, 2012 Share Posted August 13, 2012 Hi Tukko Yes you are right. You will also notice that for the first 500 miles ( 800 km ) it will feel 'stiff' intil it is all settled in. ( I had the same with the new 2.5TD in my Ser 3 ) Regards Tim Quote Link to comment Share on other sites More sharing options...
