Thread: Discovery TDi 300 Sluggish on takeoff

I recently did a bunch of tune ups to the wifes 300TDi disco. The exhaust made a difference, the pump mod made a difference, a new air filter made a difference. And something my mate with a patrol suggested, I removed the intercooler and flushed it out with brake clearner and got all the oil out of it, this actually made a big difference. Anyone got any good suggestions on how to stop this oil transfer in the crankcase ventilation?

I also replaced the two flexible hoses going to the intercooler with silicon units, as they were soft and expanding, this made a big difference down low.
All in all each mod only made a small improvement but all together thay added up to a reasonable differance.
I have a feeling that the flexible joint in the exhaust is starting to collapse. So a new slightly larger exhaust is next on the list.

Cheers

You need one of these Provent doovalackies....

Have a chat with Isuzurover, he's the man

Another another another 300Tdi Provent Install

Wow....talk about feeling like living under a rock! Where was I when this was happening?????

That's pretty much what I was thinking of. Don't know about the $$ though.

Cheers for that

It seems to be working well on mine, I hardly have any oil residue in my intake lines any more and im sure I can improve the plumbing on mine so it could work better.

im thinking of fitting a second gas tank so that i can have a better range, i dont have that prob of servos being that far apart though they would be about 100'ks at most id have a deisel if i was doing a round aus trip though

Hi can you elborate on the exact procedure you used for flushing the intercooler. What brake cleaner did you use ? I've been thinking of doing it but am afraid of the risk of overunning the engine on the residual vapours.

sorry is this a hijack ?? it is related to the original subject.
