I don't know WVO messed up my first turbo, but judging by the pictures it is a likely suspect even though turbos have gone out at 80,000 miles.AnthonyTDI said:I don't get it...
If WVO messed up your first turbo, then what messed up your second turbo? You said that after the first turbo was replaced you stopped using WVO and went back to stock. Which means your second turbo was on diesel or B100 right? Then how did it get chewed up in 1000 miles? What damaged the blades on the new turbo so bad and so quick that needed replacing again?
It couldn't be WVO as you weren't using it on this second turbo right?
Can you explain?
You are correct. I used no WVO with the first VNT-17. It was destroyed by a foreign object. There was probably a shard from the stock turbo somewhere in the intercooler lines and I didn't get it out. It got sucked up on the way to Missouri and fortunately for me shaved the impeller very precisely. All the damage was on the compressor side, exhaust and shaft was fine.
Charlie (Kerma) also said that crankcase oil being blown into the intercooler by the tremendous blowby could have damaged the new turbo (lost 2 quarts going to Missouri). His analogy was rain hitting you on a motorcycle. It hurts. Make it faster and it can cut. Interesting theory but Franko6 and I think a harder object than oil got in there and bounced around especially when you look at the little pits on the turbo intake.
Chalk that up to a big $$$$ mistake for not cleaning my intercooler lines. Charlie helped as best as he could but it still hurt. We didn't make that mistake on the second VNT-17. You could eat out of that intercooler now .
I made some mistakes with my WVO system like oil change intervals. Could I correct those and go back to WVO? Sure. Maybe I will be successful, maybe not. I risked it before but dont want to again. I am willing to make biodiesel. That is also risky but not as much as WVO. It is an experimental fuel and I experimented. I saved thousands and now gave back those thousands. Hey....it was a learning experience and was kinda fun. I had a lot of interesting chats about what I was doing. Frank06 has made me whole again and time to move on.
I am going to really enjoy having compression and Charlie's Aligator tune. Compression is a good thing.
