My cruise hasn't worked since I bought my '87 over 15 years ago. Today I replaced the multi-function stalk, and now it does engage, however it immediately goes to full throttle and accelerates out of control. I tried setting it to 55 and by the time I turned it off it was up to 80. All of my vacuum hoses look good, and the check valve seems fine. Any ideas?

How can I find the dxf file for suzuki ECU ... 33920-71EG0, thanks you..❤❤❤

It always amazed me how GM made some of the best engines ever built and some of the worst ones built sometimes at the same time! The LS is probably the best small displacement gasoline engine ever built. While the 3100, 3400 v6s are in my opinion the worst. I’ve yet to see a stock one that will last more then a hour or two of hard driving before blowing a head gasket or throwing a rod. Even just running one at 3,000-4,000 rpm for an hour or two will result in a blown head gasket. The only fix is cutting the block for orings and installing head studs. Having to run studs, O rings, and copper gaskets on a stock daily driver is absolutely insane, yet GM built millions of these POS’s without fixing the problems for a long time with zero fucks given. This is the same company that gave us the wonderful EMD 567s, 645s, 710s, the 71 series Detroit diesel, the SBC, BBC, and LS engines.

That valve you point out that failed was very common in the year model.

You may have just made up my mind for me. I have a 65 gto and was keen on getting rid of the old 2 speed trans. I have a BOP pattern turbo 350 and an early turbo 700. The turbo 350 is cheaper to rebuild but i also need to raise the rear gear ratio. The turbo 700 would not need a rear ratio change but needs an adaptor plate that looks a bit flimsy. I think i will go with the correct bell housing now to avoid fitting a hinge in my driveline. Cheers.

Thanks for the explanation always good to hear what the engineers were thinking at that time. To me the LS is not worth all the headaches for this older fella. The old way and blocks were easy to work on, etc. Im enjoying learning the 92 tech on my sb 3.1 litre v6 (189 ci) Camaro RS! Very fun motor with good pep and drivability and probably gas mileage. It has the 4L60 - first year for the 700 changeover to 4L60. My car is the only one at any show with original v6 in it. Crossfire injection ( I noticed the Fieros have these engines too - some 2.8). I appreciate you teaching us about these LS motors though! In a few years, no classic car will be without one at the rate people are installing these computer-heavy tethered engines

Wow, what a lot of effort! One note, hopefully helpful to folks checking in 1+ year later: For the lower shift cable, early Mercruisers had a spec of 5-7/8” rather than 6” center-to-center. Around the late 90’s, that changed to 6” instead. I don’t know how you might have gotten an early cable in a newer boat, but they started dimpling them so they couldn’t be adjusted. EXCEPT you can use a 1/8” bit to drill out the dimples (not too deeply) and restore adjustment! On my boat, the upper (remote) cable doesn’t adjust at the barrel nut. That bit just swivels around the cable, but can be clipped at one of two fixed starting positions. The adjustment is made at the cable tip, with a jamb nut. Must be a weird after market thing. It’s given me fits making my adjustments.

Where did you buy that nice sharp corners socket?

Great video! Love the tech info

sbc is way better "structural oil pan" dumb idea lol. As mechanic I can tell you the changes made from the sbc to the LS made it harder to work on. The 2 piece rear main you could change in an hour or two. the one piece rear main takes 4-6 hours because you have to remove the transmission. And why in the world would they design the LS to where when its installed in the vehicle you have to remove the heads to change the cam. I wish they never quit making the sbc.

Back in the 70's and 80's cracked flexplates were pretty common on SBC. Since the LS came out, I have not had a cracked plate. I attributed this to the full circumference of the bell housing. 47 years in GM dealerships, I've seen it all.

I never knew any of this. Great subject and class at GMU!

Great explanation and the drawings really help. Thanks for sharing.

This must be a big part of the reason the LS mains and Rod bearings, seem to last forever, and can take upgrades to 1000 HP and survive! However, in my limited experience the cam bearings don't survive as well, great engines I've put a lot of miles on 6.0's. If I may, what truth is there to GM bringing in some racing engine builders to assist in the LS designs? Thanks

Thanks for the info makes since

I can relate to this because back in the 90’s when I would rip the engines out of these older GM vehicles with our SAS Engine Biter attachment every bell housing would break and just the engine would get ripped out. On GM RWD models from ‘96 on the whole complete powertrain would rip out in one unit due to the full bell housing giving enhanced reinforcement.

what was the torque on the pan bolts?

Great video and with giving so much detail, really helpful. I have a similar problem and am finding the shift lever stiffer coming from reverse to neutral. Works great when out of the water but as soon as the shift interruption plate gets involved when in water it becomes much stiffer. Didn’t realise you can adjust the switch but also think the spring seems overly stiff also. Would be great to see what your shifter travel looks like when under load if possible

People used to have leather belt holsters for slide rules. 😂

Level of sulfur, cleanliness and proper octane BimmerN53

Only problem is “000” you get the numbers easy but the noughts a nightmare imagine mating mistakes of “000” s

Very well done videos thank you keep it up wish you could help with my sons 87 gta 😢

Great video! Only have 30hrs/2yrs on my 4.5, and have been having stalling issues when shifting into neutral on occasion. Had a boat mech change out my prop a few days ago, and he showed me this was the issue. Nice to see a video of it being changed out. He mentioned instead of paying him for a easy job (1 hr minimum charge) I should just do it myself. This video definitely gave me the steps to do it myself. Also, I must add the mechanic said using stabilizer( Sea Foam) specifically will destroy the filter faster which in my case is most likely what happened.

I graduated BSCE in May 1969 and still have my K&E slide rule. I think it was 69 or 70 when HP came out with the 40 or 45 but it was $450. I finally bought a TI scientific calculator for about $30 or $35.

@bitsofwisdom460. Haven’t seen a slide rule in years sir! Just asking - have you ever seen a “spiral” slide rule? It looked like a two stage telescope and you “twisted” one tube in or out of the other to make your calculation. I think the “cursor”/datum line was on the bezel where the smaller tube passed into the larger one. Apparently since the action was spiral/rotary, this effectively increased the potential length of the slide rule - beyond the fully extended length of the tubes. Hence the calculations were more accurate! Probably a specialised type of slide rule for a specific calculating task. Thank you for your video. Stay safe and well.

I was at secondary school in the sixties, and while I did have a slide rule for quick calculations, the calculating aid de rigeur was my log book. All calculations in exams had to show your log working, and wow you had to be good at adding and subtracting to use them quickly. They mainly gave answers to 4 figures which you reduced to 3, but it was possible to find logbooks with more .

An analog computer...a slide rule.

Hi Dan I have a question for you about the charcoal evaporator canister(305 TBI): the other day I found a great ammount of fuel in it and in the vent line from the tank too,my check valves are all new,the Camaro manual says to replace the filter in the canister but mine is sealed at the bottom,no way to open it so my idea is to delete that canister because of safe you know,I don’t want my Camaro in flames for that problem.What do you think?Is it possible to delete that?Thank you.

I still have mine from college days. Bought it in 1968

De e la en räkensticka!

At yard sales and thrift stores once very expensive Eugene Dietzgen Co. slide rules can be had for a couple of dollars. Like a Dietzgen Maniphase Multiplex Vector Type Log Log Rule - Cat. No. N1725. Some of its scales are so small (on the LL3 & LL03) a magnifying glass would be needed to see it well enough to use accurately. I can only use it to multiply and divide. I still have my 6" aluminum Pickett slide rule my mother bought me in High School. Ditto drafting machines and scales for drafting machines.

I have no fans at any speed working. Resistor isnt the issue, replaced the old one, still nothing. Now I've tested my fan speed switch it checks out ok. I'm guessing its not the high speed relay, as none of the speeds work not just the high speed. What should I investigate next?

We called these “ guessing sticks” as you needed to know approximately what the result would be. My maths teacher made us learn the square of every (whole) number from 1 to 20 and every number at 5 increments up to 100 - which also helped when using Logarithms.

I still have my 6” and 12” K + E. Amazing how fast we got with these. I owned an engineering firm for over 30 years and I was always amazed at how my engineers with calculators lost the concept of about what the answer should be, especially orders of magnitude. And trying to explain to the newbies how a six digit answer was wrong when the original data was only good to one or two decimal places. Hard to believe the 747 was designed with slide rules and drafting boards in only about a year…

I believe significant digits and %error were taught in all chemistry and physics classes both high school and college. It is amazing how people conveniently have forgotten and ignored that concept. It is also disturbing how the financial world completely ignores it! They are making business decisions without understanding the accuracy and errors in their numbers.

My grand mother used to work as quality control in one French company that built slide rulers. so yes, I know, I have had free (slide and not) rulers all my life, I am about to retire and still use one of the free rulers that got rejected by QC and she gave to me. I think what you missed to say is that slide rulers were based on logarithms, so it replaced a multiplication by an addition: to multiply 2x3, you aligned the origin (1) of the moving segment to the number 2 on the fixed segment (that is log(2)) and moved the reading transparent bit to the number 3 (log(3)) on the moving segment. Just below that, on the fixed segment, you read 6 (log(6)) because you just added the length of log(2) to the length of log(3). That was the first (and only to this day) practical usage I saw of logarithm. Slide rulers also taught you to think about the result rather than blindly trusting the number displayed by a calculator (and ignoring a possible miss type on the input).

I went through school just after the introduction of calculators into the classroom. I remember the big slide ruler above the chalkboard. Never was taught how to use it but always carious about it. I have pick up couple of the slide rulers from estate sales. I wasn't able to figure out how it is used. Thank you!

When I went to college a slide rule was mandatory. Even when electronic calculators became available we couldn’t use 4:59 them in exams. We had to use a slide rule

I graduated high school in '63. I had a Pickett Trig rule in HS. In the Navy I got a Pickett electronics 'rule and bought a Sun-Hemi 'rule when I got to Japan. I have about 8 or 9 'rules now, 2 of them circular, 1 a binary rule. The nice thing about 'rules is they don't require batteries and you can take the slide out and use it to make a logarithmic graph. They have also outlasted a lot of calculators. The Oughtred Society is THE goto place for Slide Rule info. You can buy many different kinds, even make your own, from Sphere Research in Canada.

I (still) have one - Darmstadt .

yes I had one until my EX walked off with it

I had to use a slide rule throughout my engineering course at college, although we did use hand-cranked mechanical adding machines for one of the exams. Like you, I also had a 6 inch pocket slide rule. It was remarkable how much could be done on these simple devices. I bought my first electronic calculator (a 4 function Casio) in Japan for Y20,000 in 1973, but I still kept my slide rules for a few more years.

Ahhh you are young buck!

Fascinating.

You could do a whole series on the old style calculators. I remember the engineering students walking around with the leather slide rule scabbards hanging from their belts. I got a bamboo slide rule with a plastic covering. It was a log, log, deci, trig unit. The bamboo was supposed to be more accurate than the plastic ones. There were books out on how to calculate how good or badly inaccurate your slide rule happened to be. Problem with the plastic ones was the slide tended to get crooked after a while and your accuracy would be off. Prior to the hand held calculators were the desk calculators running on 110 volts. After you punched in the numbers and hit the calculate key the Frieden units would start to whirr, then go ka-chunk, ka-chunk, ka-chunk unit they finally finished the calculation. Because of the lack of calculators my statistics class had a whole chapter on how to manually sort data. We'd spend hours doing data sorting. Now, you just put the data in an Excel spread sheet, press the enter key and the data is sorted. And, of course, Excel does a lot of statistics work as a matter of course. We'd spend hours looking through a data list to find highest/lowest numbers. Spend a lot of time calculating average. Now, all done in less than a second by the Excel sheet. Ah, the good old days! ... Not!

Used one all through high school, didn't own a calculator until much later.

you don't look old enough to remember those. I was the last in my class to use one (1978).

But I do know that one and one is two / And if this one could be with you / What a wonderful world this would be

this brought back memories for me too as i was doing Industrial arts subjects in high school and all we got was slide rules to do all the calculations. I still have mine in great condition. Its a Kent 309 Student and still works fine. As you mentioned when calculators first came out in the early 70s I wanted one because i was racing pigeons at the time and needed to calculate accurate velocities. I got a remington Casio for christmas . Cost a huge $52 australian back then was very expensive, and it only did the 4 basic calcs. When i went to Uni i got a Texas Instruments Programmable Calculator and that was great. Still have that too and it works but the mag strips (where you saved the programs) don't read to well now.
