I have the new intake tube now so oil doesn't drip oil down onto it anymore. But down around the area where the swirl motor is, it has almost 30K miles of burnt, caked on old oil residue/carbon still down there from when it did. I'm thinking it could go out or start acting up at any time. Just wanting to know what to watch for.
start by searching in this forum for the word "swirl" and then sit back and read.
I've read a couple threads now about guys that pressure washed their CRD's engine and reported no ill side effects, mostly after oil leaks. I've briefly and carefully washed the area below my turbo tube just to try and wash away the residue that was on before I bought my Racor and so far I've not had a problem, maybe you want to try and do some washing like that too.
