Can You do engine flush with diesel fuel???

[guywithblack88e30]

Ok so this guy I work with told me a can do that he did this before to his 2000 caddy, and it cleaned it really good. He said that when he drained it it came out dark dark dark black. When u looked inside the with what he he could see it was really clean has anyone tried this on there e30?????

Well, since all you're doing is sending stuff through the cylinders, I guess you could do it without there being too much residual fuel to mess up your engine. I don't know why it would clean anything though.

Find something dirty, pour some diesel on it, and come back in an hour.

Gunk sells an engine flush that works for badly varnished engines, if you have alot of crud and chunky deposits you don't want to use any flush. The flush will break the chunks and it will then get traped in your pickup screen starving your motor for oil. The only time I ever advise an engine flush on a heavily cruded up motor it when you are pullng the oil pan just after the flush so you can get all the crap out that it breaks up out of the pan.

I recently used some "Engine Flush" on my '87 Isuzu Trooper since I was resurrecting an old engine. The guy at Advance Auto Parts said it was mostly kerosene (very similar to diesel fuel). Instructions on container said to idle at 1500-1800 rpm for 5-10 minutes and then change oil. I don't know how it would affect BMW's but it did clean up the oil in my Trooper.

I'd probably only do it if there is sludge/dirty oil in the engine that won't come out with the normal oil change.

Noted.
Guess I'll be doing either this or the seafoam (hell, maybe both) right before I do the oil pan and valve cover gasket next month.

Sucking extraneous things like seafoam / techron / etc into your vaccuum lines and holding the car at idle will ruin your cats if done more then a couple times during the life of that particular cat.

You've been warned.

(As a side note, this procedure works very well.. the cats just dont like it)

Funny, my cat is the reason that my car is so loud (it's gone/separated/rusted/whatever). SOMEHOW it passed inspection last year, but this year, there's no way. So I'm going to be cheap, buy a CatCo Universal, some pipe, and have that welded in (obviously after I do all that other trash)
Thanks for the warning.

So to do this properly, one must disconnect the exhaust.

oooohh that would be soooo awesome. I might just have to do that.
No Exhaust + Seafoam smokeout= AWESOME.

indeed.

thing is though ... if i took it off and ran the car without it, i'd probably be tempted to never put it back on. :lol:

Les keeps telling me that I sound like a civic with a fart can. That's enough motivation for me. I like the way it sounds too.
