It’s become quite a popular topic of conversation lately! Pretty simple to resolve in my experience but will reoccur unless you “cut” the injector seats to remove carbon. I did mine four times over the last couple of years and only succeeded on the final attempt after buying a cheap injector seat cutter to clean up the seats.
Have a browse through the following https://www.defender2.net/forum/topic74929.html https://www.defender2.net/forum/topic74338.html https://www.defender2.net/forum/topic67028.html And there are some photos on page 9 of my progress thread https://www.defender2.net/forum/topic53240-120.html > 110 XS Double Cab |

The copper washers are important also. So a very interesting feature on Britannica Restorations YouTube channel. I was always lead to believe that the difference in these was the thickness etc. But it would appear that the cheaper ones are copper coated mild steel! As steel does not compress/form as well as copper they don't seal properly or only in the short term. Simply check them with a magnet. If you can pick them up with a magnet they aren't any good. Let some others weigh in on the blow by issue though. Just to be sure you are barking up the right tree.

Ok I had the seats done, replaced all washers and the exhaust coming from the oil cap has dropped dramatically. So it’s definitely made a difference.
I cleaned down the engine and gave it a good drive for 40km Or so and held it in boost where possible to push the seals a bit. After this there Is still a minor leak coming from the fuel pump cover. No where near what it was but wondering if the seal is no good as it had leaked from there before. |
