Come along with Eric O. at the SMA shop as we have a look at this 2001 Chevrolet 1500 5.3 that came in with a lean misfire. The engine light is on with codes P0300, P0174 and P0171. Ends up not being your average intake manifold gasket leak.

@motorhead6763 7 лет назад

Usually a intake gasket leak leans out only a few cylinders. One can pin down by cylinder efficiency test and or smoke test intake manifold and see what comes out of crankcase. Aluminum intake and heads expand and will seal up only if a piece of the gasket didn't come off from vacuum. Brake vacuum booster also common issue on older stuff. Excellent show. Thanks.

I have a 2001 Chevrolet S-10 4.3L, and it doesn't go into closed loop until around 140* F, which is normal for these vehicles. Mine usually takes around 5 -10 minutes or so of idling to achieve this temp; even less if the vehicle is driven. Maybe only 5 minutes or so when I drive it, of course, depending on ambient air temps. Great video as always!! Really appreciate it!!

@SmittySmithsonite 7 лет назад

I need to get me one of them smoke machines! I never would've found that one, I don't think. Just had a '00 Taurus here, 3.0 DOHC, with the exact codes. I did the ScannerDanner water test, and could hear it getting sucked into the upper intake manifold gasket. The P0300 then changed to a P0305 as it warmed up. Ran real rough cold, and the freeze frame temp was 64° - was confident that was the issue. Ended up doing the lower manifold gaskets too, and the #2 & #3 coil packs, since I had just changed the #1 this summer for a misfire. Checked out the fuel trims afterward, remembering you mentioning that in one of your vids, and they came right down! Was a happy day for me! Things don't normally go that smooth around here, lol. I owe you and ScannerDanner ALOT of beer. ;)

It is cool that he has made a good name for himself. Frustrating for me as I cannot find a SMA type shop in my area. Seems to be the motto around here is Guess not Test. and if you try to get them to own their mistake you get some run-around. Dr. O is a stand up guy!

@xx3868 5 лет назад

as a cheap alternative to the smoke machine, use a fat cigar and a rubber glove over a round part of the suspected pipe system. then blow lots of smoke in till the glove starts to expand and become inflated then squeeze the glove which will force pressurised smoke out of any weakness/leaks if not already leaking out of. Works great!

Most DIYers won't have access to a smoke machine, but that WAS a quick way of finding the leak ! I assume you always verify your repairs, something I am not certain all shops do.

Well, you could always burn a stick of incense for smoke, play some Jefferson Airplane, and mingle with your Zen Buddhist friends..... or not.

@theoldwizard998 7 лет назад

I found a couple of home made smoke machines on RU-vid. The cheapest and simplest was a plastic peanut butter with a couple layers of aluminum foil in the bottom, a low pressure air inlet and a smoke out let. Light one piece of charcoal and place it in the bottom. Add some shredded cardboard and screw on the lid.

@davidhoekje7842 7 лет назад

The way that the short term trim went to -10 and held there, and it jumped out of closed loop, suggests to me that it's a software routine to protect the engine from sudden unexpected operation. I don't know if the -10 short term adjustment was used during the second open loop period, but it seems likely. The behavior looks a lot to me like an intentional routine, maybe to give the O2 sensors time to heat up more.

Hi I am a new subscriber and I am enjoying your thought process and use of tools to logically troubleshoot problems. I am not a mechanic, do not have a shop and am retired. I do look forward to viewing your videos and want to thank you for taking the time to do them, you have become one of my favorite channels to watch. If you have covered this before, if so forgive me for asking, but how do you keep track of all the hardware and parts while waiting for parts and machine shop work and not lose anything? When I work on something, stuff gets dropped, misplaced or I forget where or how it goes back together.

I had this issue on my 2000 silverado, after manhandling the flex tube with intake gasket change. I bought the dormann replacement, which was not formed quite right. I am petrified to bend/contort the tube so it bolts solidly to the block. I have two gigunda zip ties holding it to the oil filler. and natually I broke off the two bolts at the exhaust, which meant for a fun Sunday of drilling in a place where you can barely get a wrench. any suggestions on how to bend this tube and get it properly bolted?

@leebarnes655 7 лет назад

I didn't really catch that part, he did say that they will cause both rich and then lean conditions though. Just be sure to try and blow thru the new one as they often come from the factory already stuck open -- just because it's new doesn't mean it works these days. Cadillac forum had one guy with four new ones before he thought to pucker up and blow thru them, and all were open. Refueling loads the canister with fumes so it's hard to start and when it does finally, the engine revs up out of control so severely that many shut it off, just to repeat this episode several times whenever they fuel up.

@sknemo 7 лет назад

6:50 in Eric says " they usually have other complaints like hard start after filling", or something similar. Thanks for your comments, I'll be checking new ones from now on!
