Holy thread resurrection, Batman!!!!
Just to say that on my recently acquired TD4 I have a leak under the inlet manifold, so did what I have always done, and put it off for a few weeks (not been using the car, so not a bad thing). As there was no puddle of oil underneath I decided it wasn't a 'big' leak, or anything with liquid oil, so it was likely to be a vapour issue.....
.... but it was all too horrible to see what was happening, so a good squirt of degreaser and spray of water left me with a (still grotty, but far better) area to examine. First thing I noticed was the vacuum pipe off the EGR valve - and as it was plugged with a bolt it was clearly removed intentionally. So, I stripped the whole inlet system off (2 of the orange rubber gasket things were damaged, so it was worth doing) for a good clean. The EGR valve was carbonated (is that a word??) shut, and there was no gasket between it and the manifold.
Pretty sure that this is the cause of the leak/mess but rain stopped play today.
I intend to clean up the EGR valve, but not necessarily replace it at this stage..... can anyone tell me what level of vacuum needs to be applied to see it open? (I have yet to try it, but a non-calibrated suck through a length of vacuum hose would be my first approach.)
As the car was purchased solely for a 'banger run' to The Gambia, where it will be sold off for charity, I don't want to spend a fortune on parts - but still want it to get me there, and be worth something when it arrives......
......so.......
...... can I use 'instant gasket' to refit the EGR?
is a cheap EGR any good?
should I just delete it?
Obviously, I shall address the things that may cause the issue as well (breather filter etc), give it an oil change, and filters etc etc, so this post is purely to try to understand the EGR issue........
.....oh, and to thank the OP for recording the issue - and to highlight the fact that the search function works, and I didn't start a new thread for an identical issue
