ejparrott Posted April 28, 2015 Share Posted April 28, 2015 The fittings for the cooler end a re a bit special I think. I had custom hoses made for my 88 and 109 for the filter end and IIRC they were just 1/2" BSP. Both are 200 TDI Disco engines Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted April 28, 2015 Share Posted April 28, 2015 As a bodge to run it for a few yards could you just blank off the return and then hook the flow line into the filler cap? Quote Link to comment Share on other sites More sharing options...
qwakers Posted April 28, 2015 Author Share Posted April 28, 2015 Tried that, it cant flow in fast enough. Result is the entire sump on the floor. Quote Link to comment Share on other sites More sharing options...
Boydie Posted April 29, 2015 Share Posted April 29, 2015 Forgive my possible ignorance but if the engine is cold should not the oil thermostat stop the oil from circulating through the oil cooler ?? I know on my 300Tdi Disco this is the case so if this is the same as a 200Tdi dismantle the oil thermostat, which is possibly defective and cause the bypass past the thermostat to be blanked off then all the oil will simply bypass the oil cooler hoses - as it's supposed to do.

qwakers Posted April 29, 2015 Author Share Posted April 29, 2015 all i can tell you is 0 oil pressure and a flood of oil is the result of starting it the other day. Quote Link to comment Share on other sites More sharing options...
miketomcat Posted April 29, 2015 Share Posted April 29, 2015 On the tomcat I cut the steel pipes fitted a compression fitting with a copper pipe bent in a funny shape in between. This was because the radiator was in the back. Mike Quote Link to comment Share on other sites More sharing options...
Boydie Posted April 29, 2015 Share Posted April 29, 2015 I've just gone through RAVE and from all the guff printed there if the oil temperature hasn't opened the by-pass to allow oil into the radiator oil cooler there should be almost zero flow. Use a thread gauge, measure the two threads used by the oil cooler hoses and simply put in two bolts as a temp measure. Quote Link to comment Share on other sites More sharing options...
smokey_joe Posted April 30, 2015 Share Posted April 30, 2015 I have a bridging pipe I made up from 2 old cooler pipes using the 2 filter housing connections where I split the crimp connections on the metal pipe which uncovers a pipe with a swage on the end, then cut out a section of the rubber hose and joined the 2 together with jubilee clips. This seems to work fine for running up engines without connecting up to the radiator, I have even used this for short road tests and never had any leakage.
