Finally got er done.

[jimbyjimb]

Got everything finally finished. Runs a little rougher than before. Took it out and thrashed it like a red-headed stepchild and seems to have cleared some of the crap out and cleaned up idle a bit. I do have a ticking rocker, which is irritating, but some atf oughtta fix that. Everything seems to be fine though, so good stuff!

ATF? Old school trick that MAY have somewhat worked back in the old days when motor oils contained no/little detergent packages. Todays motor oils, especially top quality full{true} synthetics contain a much stronger detergent package than ATF.

Install a full synthetic motor oil and just drive normally for awhile, if it doesnt completely address the issue, research a chemical motor flushing agent

BG Quick clean or MMO.

Or short term high detergent oil changes in combination with the above.

[jimbyjimb]

Old school trick that DOES work. ATF is still thinner and still has more detergents since transmission fluid lasts 30,000-50,000 miles between intervals per MOST maufacturer specs. Every auto transmission I've ever seen apart is cleaner than any engine I've ever seen apart, even with the longer interval and intricate pathways throughout the valvebody. In my experience with motor flushes: they don't work as well as ATF in any vehicle I've ever driven or repaired. The dealer ran ATF through OHC as well as OHV engines for 15 minutes at idle to clean them when there was rocker noise/lifter noise, and I have yet to see it fail whether it be on an 06 or a 66. ATF elimates the varnish which is caused by motor oil, and is much cheaper than flushes that may or may not work. I wouldn't want to run pure high detergent for more than 15-45 minutes since it foams, and that's expensive. I'll admit it if it doesn't work, but has never failed me yet.

On a side note, twice today the car died when coming to a stop, only under rapid closing of the throttle plate. It did run a code, but the code would disappear upon the next startup. I didn't run the code and if it pops up again I have the ECU out and ready, but any idears? I believe the nissan comps have a self-diagnostic check I could run on the systems.. I'll check the book. I think it could be the IAC since one of the hoses I made kinks slightly. Enough to flow air, but is it enough air to absorb the impact of a rapid throttle plate closure? Mainly I'll have to wait for it to do it again and run the code, just putting it out there. There is no stumble, no trying to stay running, it just flat stops running. The tail pipe was a bit smokey low-end, but throughout the day has cleared mostly. Crap built up from sitting I'm hoping over running rich-yet another possible IAC pointer. Seems to do it when it's colder.

Yeah, but that's because there is not internal combustion blow by.

Hope you cleaned the IAC and EGR while you had it apart.

[jimbyjimb]

The EGR was gross, but I doubt that since usually EGR issues make the engine run poor in general. My car runs great, just flat out died out of nowhere. The IAC must have been new since it was spotless, but IAC's dont get too fudged up anyway. If it is the IAC the problem is my hose, which seems a very likely culprit. The metal elbow in the factory hose helps alot, my hose is kinked enough to be a little less than 3/4 open. Definitly cuts flow down a little, if it were much more it would definitly make the car run crappy rather than simply killing it. Then again, it could be a whole host of issues. Maybe it won't do it again. Eh, who knows?

Auto trannies do have wearing clutch pates, however. Those can get real bad when burned. ATF is for a totally different job, much more demand on cleanliness in an auto transmission since a small spec anywhere could ruin it's operation.

[maxnix]

Unless the hose is comprmised, I don't think it would make much difference.

Good job anyways!

[jimbyjimb]

I totally agree, a very insignificant amount, but it could be just enough... if it happens again I'll post results. I really would like to thank the older members here who cataloged their pursuits with the Q. Any mechanic is a fool if he doesn't at least view other people's experiences when available, and your posts made this job much simpler and easier. A very good resource indeed.
