Just a simple but overlooked issue caused by the previous person working on the vehicle. Click below to buy our hx30 turbo kit dieselpumpuk.com/products/hx3...
i think there are a lot of guys on the interwebs who just share their opinions as facts. Good thing that there are actual engineers out there with the equipment to prove their points. I like to watch Gale Banks.
Old video but i feel your pain with the misinformation, the exact same thing is happening here in Australia with our TD42 scene. People pumping 40psi through a 6cm housing with a tiny turbine wheel and then they wonder why they're snapping crankshafts and shooting rods out of the block. All with sky high egt for the amount of fuel and emp of 3:1 or more. Just because they want boost response and still big numbers. The wastegates simply aren't big enough to exhaust that without dropping boost and blokes run crazy spring pressure to hold their tqrget boost pressure. Just a nightmare A few of people know how to make a reliable set up but it's so hard to explain this when all the big companies write it off and are adament that this causes no issues
So, you didn't specify why the PCV restriction & crankcase pressure caused oil in the exhaust. For those wondering, excessive crankcase pressure prevents enough turbocharger oil draining from the turbo bearing housing down into the crankcase (it pushes back on the oil, increases the total pressure on the turbine shaft seal). Then the oil pressure at the turbine shaft seal increases enough to leak quite a bit of oil, maybe even some crankcase gas. Hopefully the turbo bearings & seals are not significantly damaged, as the journals require adequate oil flow and not just pressure.
Just tell it as it is Luke 👍. I don’t know where some allegedly ‘knowledgeable’ individuals get their information from but some of it is downright daft and dangerous. Looking forward to seeing a bit more of this W124.
Your videos are excellent. No muss no fuss just right to the point clear and concise, kind of a rarity on RU-vid. I have a standard shift E39 BMW that I would love to diesel convert. As much as I think the 0M06 is a fantastic engine I think transplanting and N57 or an M57 would be easier. The hardest part so far is finding a standard shift diesel transmission, apparently they never sent them to the states. A guy like me would greatly benefit from 10 minutes of your time, is there a way to put some money in the kitty and pick your brains for a little while? Please advise, Al
Good video 👍🏽 It would also be nice that in future you might make a video about your opinion about crank case ventilation system is it ok to use original one, or do custom outlets in valve cover or something like that 👍🏽
Nice! I have a brand new turbo that will not make enough boost to open the wastegate. It spools up nicely and definitely has great mid range, but feels undersized at the top end. Could a new pump and injectors help this?
Now I understand the difference between VNT turbos and Waste gate turbos with their beautiful sound.... Now how to deal with a stock vnt turbo on OM605 with no respond? I want to get a guide to start a checking. Thank you guys
I don't know about your particular application but CATERPILLAR eventually put waste gated turbos on their ACERT engines as they were seeing shaft breakage from over speed under some conditions from this high exhaust pressure choke issue, since then failures are very rare, this was at same HP rating for non waste gated spec, around 800 -1200 HP in particular. Automotive/Highway applications seem to be less harsh than constant load applications but i guess still pertinent in regards to exhaust pressure ratios
yup, been there - got caught by having mounted a quite restrictive filtering on the catch can - interestingly enough the same catch can on another 3.0 diesel didn't have the same outcome; worth noting it only happened at high revs with the OM606
I have om603 with 7mm elements and a new hx40 with #16 turbine housing with no wastegate. Max boost 1.8 but havent checked the exhaust gas pressure yet. The boost starts spooling up about at 2000rpm. It isnt a normal hx40 bc it is made for some kind of gas powered bus😂 (by holset) The turbine and compressor wheels are different size compared to normal hx40.
Engines are air pumps, faster you can get air in and out the better for power as you can put more fuel in :) if you dont have a wastegate your effectively choking the engine. Then suddenly it cant get it out so it cant get it in.
The frozen condensation in my diaphragm valve on top of my valve cover would ice up when it got below -12. It basically would walk the oil up my drain back into my turbo, blowing blue smoke all the way to work from the crank case pressure. I did short drives, so condensation was more prevalent.
why not pipe it back into the intake if it makes the engine run better? You're saying the engine runs best when the gasses are going into the atmosphere.
go show me a wastegate on any VNT turbo , go on :) ... just pulling your leg, you can run a diesel with no wastegate, but itll have limited power and is just dumb. that said i think it may be common practice on "single speed" diesel engines like generators and the like, but obviously no use atall on a performance diesel.
