Hi All, Hoping somebody will be able to help me with an issue I seem to have with my PD130. Since I bought it I’ve noticed excessive pressure from the valve cover, as you can see on the video. Turns out the breather is a sealed unit and the rocker cover is £145 from TPS which I’d rather not change unnecessarily. I’ve taken the breather pipe off, there is air and some oil vapour passing but nowhere near as much as what’s coming out of the oiler filler? The engine running doesn’t seem to be affected by doing either of these. I took the rocker cover off last week to try and gain access to the breather but failed, so refitted it with a new gasket.. the hole up to the breather diaphragm was clear. I don’t mind spending the money on the new rocker cover if I know that’s the issue, but I’ve spent a lot of money on the car on various things and can’t be careless with it. I’ve been told to run it till it dies but I’m not in it to do that, I want to get another 200k out of it.. we all know they are capable. I changed my oil filler cap at the same time as it was blowing a small amount of oil. I don’t know if it’s coincidence but ever since every couple of days is struggling to start now, coughs and splutters into life and I’m not sure if I’m not suffocating the engine so when I’m home I will be swapping the cap back I think. Any PD experts or anybody had experience with this before? From what I’ve read online it could be worn piston rings, I hope this isn’t the case. The engine has done 218k with full Audi ‘long life’ History on a mixture of what seems to be 5W-30 and 5W-40 oils. It’s now on the correct 5W-40 oil at 5k intervals with me. Any help appreciated, Matt.
