Date: Mon, 21 Jun 2004 11:14:16 -0400 Reply-To: dtlc@helios.net Looking for some advice regarding my '83 BJ60 Last Wednesday the engine started revving quite high at idle, I didn't have time to diagnose it, so I figured I would leave it till the weekend. Drove it for a few days, all highway KM's (approx 250 a day) drove fine on the highway. I helped a friend move on Saturday (about another 250 KM) and then it started acting up. At idle (sitting at a stop light), the engine now revs high, and almost seems like it is miss firing. The smoke pours out the exhaust (white blue) but again...only at a stop. This is very severe, all the cars around me noticed and smelled it (people were not too happy), though I was very happy from the fumes.... Obviously this smoke is the result of burning oil. Aside from a few leaks on the engine, I didn't really have a burning oil problem before, the exhaust was usually pretty white. From what I can tell, the white blue fumes pouring occurs only when I am not revving the engine or actually moving, it only appears when the engine is idling, though I imagine I just can't see the exhaust pouring out due to the sheer speed of my Cruiser (ha ha ha) My completely uneducated guess is that this has something to do with the injection pump, but that is why I am asking you guys, the gurus as I AM uneducated with regards to Cruisers. Help...I want my truck back on the road...and please don't tell me that this is going to cost me $2000 dollars...otherwise I may have to put her out to pasture...sigh... Thanks for your replies. I will be away from my email today, but I'll take a peek later on, I hope I have provided enough information.

It is the governor diaphragm on the injection pump. $20 and some of your time and you will be back in business. Doing a Re&Re on the governor is a bit of a pain (it is a tight squeeze to get your hands in there). Do a search of the archives (http://www.birfield.com/archives/html/dtlc/) for diaphragm and you will find some hints on making the job go smoother. Here is the part number info: >the P/N for the diaphragm is 090580-0041, we sell them for 19.20=20 >each. There is also a P/N for the Denso oil, 995500-0140, we don't have any >stock on that, I think it's around $7 or so for a "lifetime supply" sized >bottle. That clip is from Glenn at Western Turbo. Here are the contact details: >If you want to order call Jaret at 1-800-665-7556 I am not affiliated with them, just a satisfied customer. You can get the diaphragm at any Denso dealer with the above part number. Don't bother going to Toyota for it as they charge about 4-5 times as much for the exact same part. Good luck. Steve.

Get one at your local injection shop for <$30.

The problem is simple, and the fix is cheap, although a bit frustrating... OK, everybody together now... "It's the Diaphram!" Yes indeed, the 3B injection pump is one of the few in the world to use variation between venturi and direct pressure across a butterfly valve to actuate a diaphram in the injection pump which controls fuel delivery. When that diaphram wears out and leaks, you get the high idle/smoking' symptom you've described. The Diaphram cna be aquired from most Denso dealers for aroudn $20, or, in a pinch, from Toytoa for just under $1,000,000, or something like that, but it comes in a fancy Toyta box instead of one of those boring old Denso boxes, despite being the identical part. If you're having trouble finding where to install this new part, start at the throttle body, or the butterfly valve. You'll notice two large hoses going from the throttle body to the back of the injection pump. The diaphram is inside the rear housing of the injection pump, between those two hoses. If I recall, the best way to replace this part is to remove the EDIC motor (unplug the electrics, three 12mm head bolts and detach the arm from the injection pump). This gives you the room to work on the back of the injection pump. Then, if I remember corrently, it's four or so philips head screws to remove the back cover of the injection pump... Carefull, I think there's a spring in there. Then, there's a cotter pin holding the diaphram to the fuel control rod. Take it off, then put this new diaphram on, and put the new cotter pin in place. This is the challenging part, as the location requries this step to be done one handed, backwards, and upside down, with various fender bits stabbing at vital internal organs. In theory, easy, but if this is your first time, budget 2 to 6 hours with aproximately seven hundred trips to the floor to pick up the dropped parts. I like to be prepared and get several hammers near me so I don't have to look around the shop for something to throw to satisfy my anger. After only doing this simple $20 fix once, I now have a policy of replacing the diaphram in any engine I take out of any truck, whether it needs it or not, and if the diaphram needs replacing before the engine get's pulled, well, the engine probably needs to be rebuilt anyway.. don't you think? Good Luck! (It's really not quite as bad as I've said, but it is a test of patience) Peter Straub Date: Mon, 21 Jun 2004 10:31:49 -0600 From: wayne@crushersrule.com Subject: Re: [DTLC] Stick a fork in 'er...she's done???

Toyota charges a ton of money to do the job but then so does most shops. it can be done in 45 minutes if all goes well or it can take all day, and after you have flung your patience across the room maybe take a brake and go at again in a few hours... usually it goes much better on the second try... good luck.
