Seems my reply got lost in the ether. When I had the original mods done to the car in 04 they fitted a GBF boost controller and wound the pressure up to 14 psi - good or bad. The oil is leaking out of the small hole in the side of the controller ( I assume when it reached boost pressure) which means there must be a lot of oil coming out of the turbo to the intercooler. As you suggest, I will fit a catch can to the PCV line and see what happens. I have had a look at all the points for leaks as per your diagrams, other than the oil from the boost controller, there are no other leaks so we will watch this space as I have finally got it back together. (I lost the E clip on the boost arm and it took me 3 days to get a new one, problems of living in the bush) Next time I have my head under the bonnet, I will check the fan, I have had it tested however, again I am not convinced. One last thing, is there a way to check the timing of the Injector pump??? Once again, thanks for the advice. Hi Ricster, Thanks for the reply. All this has convinced me to fit a few gauges so I can see what is going on. I will start with the boost and Temp. I know the temp has been up high when climbing and I have had to back off on the pedal just to get to the top. One hill I had to stop twice to let the motor cool. It seems everyone else's patrol goes better than mine especially when towing so I am going to get to the bottom of it this time. (gives me a reason to use the new hoist) At least the car is back on the road and it seems to be a lot quieter, except for a thump in the rear but another story for another day. Thanks for the interest. Regards

Thanks for the welcome. Nothing worse than the lurkers Roland

Many thanks for the detail, I had to read it several times to make sure I had it all in order. When I bought the car new I had the 3"exhaust put on and the turbo modified and boost to 14psi. I have to say I was a little dissapointed with the outcome. The first trip we did the thing over heated going up Cunninghams gap and we pulled into nissan at Warrick to have fhe vehicle checked. We did have the campertrailer on and it was a hot day. This issue has plagued us ever since and I sometimes wonder if the engine timing is actually correct.I have just replaced the exhaust system and thought while I am under the car i may as well see what else can be done to get the power up. I have noticed some oil leaking from around the turbo, I found it was leaking from the boost controller. I am not sure if this is reasonable . Your thoughts would be most welcome. Regards Roland

I have been following this forum for some time, especially when something comes up with the vehicle. We have a 2004 model 4.2 manual patrol from new that we have taken to many places across this great country. It is our second patrol, first one was a 2000 model 3litre auto which also took us to a lot of remote places. I had a 3"exhaust with mod turbo installed from new along with diff locks front and rear and winch. Inside we did the usual things, drawers, shelves etc as well as a HF radio for communication. Fundamentally the vehicle has done a lot of off road miles with only one problem whin a rear coil cup split, however that was self inflicted. (Long story) I am currently replacing the exhaust on it and keen to do some further mods to improve performance - I have never been really happy with the performance. I am looking forward to becoming part of the forum community and getting feedback as well as contributing when appropriate. Regards Sue and Roland Cox Moore QLD

I am new (as a member) to the forum however followed it for long time. I have read the post from Dronus4x4 on nads mods which I found excellent -best I have seen for a long time however I am after the same for the 4.2. I am in the process of fitting a new 3" exhaust to the vehicle ( it has had one from new) and having pulled everything off I felt it the best time to do some mods. Does anyone know where I can find a post that discusses the mods and issues with the 4.2 (2004 model) I look forward to your i put. Roland Cox
