    Cylinder anti carbon treatment requests

    Hi, in about 1 month I'll swap out my engine (1.6IDI), but before doing that I'll try the berryman anti carbon treatment. If there's any requests people want me to do let me know. Here's my plan Before treatment 1) With cold & warmed up engine, document - blowby smoke (at night with flashlight)...

    Air intrusion, fuel filter

    hi, its either a small leak (cracked tube or whatever), also make sure that the metal lines copper gaskets are good and the surfaces are smooth. also likely, if you are using a rotary pump (like bosch), then this pump can suck with a huge amount of pressure. meaning that if theres a clog...

    Cheap way to clean out WMO even more (using water)

    Hi, the tdi swap is still on-going (rebuilding the engine), but during the x-mas days I've been thinking on how to improve my WMO production. 1) Washing the WMO Black dawg noted the positive effects of it, but there's a problem on what to do with all the contaminated water. -> There's a...

    Cheap way to clean out WMO even more (using water)

    Wow nice reading the extensive experience you have with these engines & WMO. Yeah it's been a great learning experience, the ring-sticking issues seems to be the last of them, after having dialed in pretty much everything else (filtration etc etc) haha. I boroscoped the cylinders and they look...

    Cheap way to clean out WMO even more (using water)

    After running nearly 3 years of WMO, an update: The good: - engine compression is still pristine (same as when I bought it). - the turbo really helps with burning the oil cleanly. People can drive behind me on the highway without cursing - because of the turbo it maintains power a lot better...

    Cheap way to clean out WMO even more (using water)

    Hey, sorry for the late reply. Hope you are well. For example, salt, sugar. These don't dissolve with oil or gasoline. Same with some leftovers from brake fluid / coolant , etc. It will create a suspension, true, these salts will float in the oil However, if you mix water through it, these...

    New insight in IDI burning WMO - need high compression or turbo

    I'll see if I can dremel them bigger, nice idea. Got a summer mix running now, 75%wmo25% kerosene. Winter its more or less 50-50. I'll try with RUG next, the manual of the car says I can run up to 30% unleaded. Should thin stuff out nicely. Does it evaporate over time?

    New insight in IDI burning WMO - need high compression or turbo

    this is the injector, the tip is a small needle which rocks back and forth. Gets carboned / fouled up over time. just alot faster with wmo Here's one from the net, after running it 100k miles +- Mine looked the same after only 10k. The headshields are in the first post.

    New insight in IDI burning WMO - need high compression or turbo

    Update, the heavy towing stuff didnt work. The car was starting really hard and lots of unburnt diesel smoke (even when running on straight diesel). Heat shields were full again, however it appears to me that they get clogged much faster than before. Pop tested the injectors and they were all...

    Removing VE-pump anti-tamper cover w/o damaging it?

    I hate this screw, I destroyed many pumps bcuz of it. You can actually turn the screw in 1-2 more turns even with this collar on, lol. I finally found a injector-shop who had some spare screws lying around and took a bunch with me. My guess, if I had to do it would be to clamp it (through a...

    Polymerisation lube oil

    Check out google images and youtube for "engine oil sludge"; https://en.wikipedia.org/wiki/Oil_sludge more frequent oil changes seem to be the remedy. Assuming you have the 1.9D (the IDI), e.g. AEF or AAZ, 24bar is out of spec, yes, BUT it will run fine. I have a 1.6D, runs and starts with 2...

    thanks for all the inputs, will do! Once the power decrease sets in again, will do that heavy towing, will be interesting in seeing if it clears things up or not =)
