Date: Wed, 13 Sep 2000 23:21:49 EDT Subject: Re: Heater not heating in Alaska I'm missing somthing here. How is restricting the flow in the bypass hose going to reduce the flow to the radiator? NOw I'll agree that installing an orfice will reduce the flow through the block (when the thermostat is closed). If anything it'll increase the flow through the Rad (when the state is open of course). It's much like parallel circuits in electronics, restrict one path, and the others get more (given the flow is there). George M in Fl.

<< I agree with John here. I'd also like to add this:: Try restricting the bypass hose (the one that bypasses the T'stat). It is about the size of heater hose, but in drastic climates such as in Alaska, it might help to take one end of that hose off and insert a short piece of plastic pipe that would act as an orfice and restrict the amount of fluid that is allowing the coolant to go into the radiator, thereby allowing the engine to cool....

There's more to it than just building a hyd. generator. One source of info claims you need to replace all inside engine components (valves, pistons, ect.) with stainless steel because the burning of hyd. produces water for exhaust instead of carbon monoxide ... NO POLLUTION. Another sourc claims stainless components are not needed if the vehicle is used every day. Experimentation is needed I guess. Be very careful with this kinda stuff. The oil companies and gov agencies DO NOT LIKE this! As a couple examples: ( I forget the exact dates) In the 40's, a canadian named Pogue (I think) invented a vaprorizer carb that got 200 MPG in a V8 Ford. Where is this carb today?? -- The Model T engine was designed with holes in the bell housing which would except cow magnets. Once the engine was started, it would run with no fuel due to magnetic forces. A couple guys once demonstrated this at a alternative energy exibit. That evening, these 2 guys were found, car ran of the road, their throats slit and the engine missing. I'll find that article an post it. -- In the 50's, Rory Johnson invented an electro-magnetic motor the size af a 20" truck rim that produced around 500 HP. Both johnson and his motor mysteriously disappeared. OK, enuff of this.

This is the first one that I've not been able to warm up. It even gets the garage while my wife's new byew-ick stays outside. If I didn't garage the darn thing I'd be a popsicle (exaggeration) and the windows would frost over (reality).

Subject: Re: 400 dyno results Date: Thu, 14 Sep 2000 04:21:39 -0700 In the mid seventies I was a kid working at our family gas station. A Pantera drove in for gas and the owner and I got to talking, since his car had the same 4v Cleveland that I was trying to stuff in my Torino GT. He told me that one of the selling points they gave him to buy the Pantera was a 200mph guaranty. If you take it off the lot and it doesn't do 200, bring it back and get a new one. He said he was never able to go that fast, 160mph, if I remember correctly. Not because it wouldn't do it, but because of nerves and finding a road here in Western Oregon that was straight enough. I've had lots of 351C over the years and I don't know a reason not to use a 4v in a car application. I'd like to see the dyno results for a BUILT 4v 351C and compare that to the 400. I don't drive cars anymore and I would never suggest a 351C for a truck.

Subject: Re: Crossover Pipe for Dual Exhaust in 69 F250 Date: Thu, 14 Sep 2000 09:16:26 -0700 The best header for an I-4 is a tri-Y and single exhaust. This may also be true for the I-6. The pulse phasing improvment you get with this setup overcomes the advantage of two exhaust pipes and at low rpms in large engines this is also true......if you can get the pipes all the same length. I will say that this is for an engine that see's mostly touring use, not racing. High rpm is a different matter. For that you want all single pipes about 2' long, the size of the ports, angling back and down at about a 45 degree angle.......... On an in line engine using a single exhaust is easy but on a V-8 it can be a chore to get them crossed over without adding too much pipe to the off side which is one reason most use the dual and cross over/balance tube method on V-8's. Tri-Y headers may still get you a few ponies on a V-8 too but were invented for 4 bangers to even out the pulses. On a V-8 there are at least two pulses which don't work with this system as well so the effect is less apparent if it even exists. I'm going out on a limb here to say that the tri-y and single exhaust is my recommendation for the I-6 and equal length headers with balance tubes probably will work as well for most people on a V-8 as the tri-y's but the best exhaust I've had on my 460 so far was a cheap Walker two into one system, it even had better top end. (my fuel pump just died though so that may be why I was losing some top end :-)) BTW, equal length headers on an I-6 must be some serious space hogs, eh?

Subject: Re: October 4-Whl&Off-Rd, Thermostat question Date: Thu, 14 Sep 2000 09:31:38 -0700 If we stop and consider what happened inside your engine under each of these situations it's pretty easy to see why they over heat. In every case your engine was making max power......and heat. This is way different from just cruising down the road...... Azie's suggestion was on the mark since the thermostat never opens under the conditions that were described so under cruising conditions the engine never gets hot enough to open the thermostat but I suspect in the case of the cold truck that started this thread there is more wrong. If the hoses are correctly hooked up and the core is the largest one you can fit and it is in good condition and you have used the card board to get the engine temp up all to no avail then your engine is not producing much power and is probably wasting fuel to boot. It could be as simple as a good tune up including rebuilding the carb. An inefficiently running engine produces MUCH less heat. One other suggestion......if the radiator is not properly filled and it's height relative to the engine is not correct the coolant will not flow through the heater regardless. On most of my ford trucks it only had to be down a few quarts to do this.

Subject: Re: Cheater Bars Date: Thu, 14 Sep 2000 09:53:06 -0700 My guess here is that he got them so tight that they cracked and when you tried to back them off the friction in the dry threads overcame the reduced strength of the lugs. As I said, I've used cross wrenches with all my strength to tighten them and never ran into this problem. I now use anti-seize and a 1/2" impact and simply watch the socket so that when it stops turning I quit, I don't keep hammering on it once the socket stops moving. I also do this a little at a time all the way around and go over them about 5 or 6 times, allowing it to get a little tighter each time using a cross pattern to keep the pressure even on the wheel. I use this method on cast, forged and steel wheels with good success. On small vehicles with smaller lugs than my trucks I also stop hammering a little sooner.......it's all feel :-) Of course I'm sure we are all aware that there are different torque capacities in 1/2" impacts too. Some can get stuff pretty tight so you need to learn how your's works and get that feel with your specific tool. Mine is about 25 years old and still working pretty well but I have an auto oiler in my air line and before that I used to squirt some in now and then :-) I'm actually kind of amazed it still works as well as it does :-) There is a torque specified for lug nuts and it is a good idea to use it if you can but as long as you don't over do it they will stay on most of the time.....I've never lost a lug nut in my life and never had a stud break on any vehicle I've had.

There are TWO top-dead-centers (TDC) in the 4-stroke cycle. One is the power stroke (both valves closed) and one is the exhaust stroke (exhaust valve open). If you put the timing mark on TDC, you only have a 50/50 shot of getting the right one. If you get the wrong one, your distibutor will be 180 degrees off. So, pull the number one plug and stick your finger over the hole. Then bump the motor around until the compression pushes your finger off. Then continue to rotate the engine by hand up to TDC (in the same direction of rotation). This should put you on the power stroke without having to pull the valve cover to check the valves. Also remember the distributor gear is spur cut which means when you drop it in, it is going to rotate a little. So you need to start out with the rotor pointed BEHIND the intended mark so that it will rotate into the right place when you drop it in. _ _| ~~. John Strauss \, *_} jstrauss inetport.com

On R&R jobs, I've found it pretty rare that I can achieve anything approaching equivalent degrees of "clean, dry threads" from one bolt to the next. Ever since I twisted off a tranny pan bolt with a torque wrench I've been a little obsessive about this stuff. I quit using the torque wrench so much and try not to work on trannies in the winter time anymore. : ) So if "modern" theory recommends and assumes light lube, in what time frame could one expect printed torque specs to have begun assuming same? I have manuals for, and regularly work on vehicles ranging from the late '60s to the mid-90's. How do I decide which method I ought to be shooting for.

Subject: Re: Cheater Bars Date: Thu, 14 Sep 2000 10:24:36 -0700 Ok, it's really quite simple. I grade 8 bolt will handle so much torque and so much stretch before it becomes permanently damaged. Torque specs take this into account and leave some room for error. Your transmission pan bolt probably had been over tightened at the factory and was already damaged. You would not beleive what they do sometimes to get stuff down the line........ When you torque a dry bolt you are twisting the bolt itself at some point rather than stretching it, this adds additional stress to the bolt and is more likely to fracture it than if lubed. My guess is that most of the documents which state "Clean Dry threads" were in error to begin with. Engineers make mistakes, documenters make mistakes, mechanics misunderstand stuff and when the book gets printed the girl doing the editing rememberd seeing this somewhere so assumes that the draft was in error and the person actualy meant.......... and on it goes. I doubt if the numbers have changed much from one to the other and the fact is that good mechanics have been ignoring the "Clean dry" part of the directions for hundreds of years simply because you just cant get them completely dry most of the time. What I'm saying here is that the torque specs usually have a margin built in so it shouldn't matter, use a little oil or anti-seize on the threads, you'll be glad you did :-) You can tell when a small bolt is not doing what it should and it's time to stop. I use a torque wrench faithfully but I use it as a tool not a master, I'm still the boss :-) If it feels like the bolt is not doing what it should I get out a box wrench and "Test" it. If it feels mushy I get a new one and if it still feels mushy I put in a heli-coil. My bronco has one less clutch bolt in it than it's supposed to due to someone else getting a little too happy with a wrench :-( I didn't have a heli-coil that size handy and wanted it done so threw it together but that's not the right attitude, should have fixed it right :-) One exception though is sheet metal screws. It's better to put them in dry and coat them afterward with a sealer to prevent them stripping. Michigan Pot Hole Jumping, 78 Bronco Loving, Gary :-) > one bolt to the next.
