Hello all,
Still investigating my R3m and establishing the optimum running of it. Just to recap it's a 1993 terrano with TD 27 engine which has an air intercooler fitted to top of engine under a bonnet scoop. I am led to believe that this has been added as mod as this year was not fitted with an intercooler,but in investigating I have found 2 small hoses not connected from the EGRC solonoids A&B, The intercooler has a little spiggot coming from it which is blanked off using a cap and also within reach of the hoses are 2 open ended look like brake pipes, I i traced to top of gear box and other looks like it goes back to a little pot by the fuel tank. I found a vacuum hose diagram and it shows hoses to and from the solonoids A&B going to EGR Valve and also throttle control valve this is my problem is that my engine throttle control valve doesnt have a hose connector on it. So if anyone can help with some advice here I would be grateful. My questions would be;
Is the spiggot on the intercooler where you would connect the throttle control valve hose?
Where does the other hose go to? The diagram suggests the other hosing goes to vac pump,brake boost, egr valve, speed sensor and throttle control valve.
If the intercooler was added to standard turbo engine is it possible that these hoses were not connected because they are not needed? or because the fuel/emmission control is not compatible?
Lastly and hopefully not but is there a more sinister reason these hoses have been left unconnected? or just forgotten.
Sorry for long post but loving the terrano just want to get best out of engine and suffering from lack of a service manual for the TD27.
Many thanks
