Need some help, I have an 85 GMC Sierra and it doesn't have any spark, I changed the cap, and rotor, had the coil, and module tested and they tested good. BTW just changed plugs and wires this winter. My next step is to take the entire dizzy out and test the pickup coil. I have taken the hold down bolt and clamp off marked the dizzyand the engine to put it back, but it will not come out of the engine. I have never taken one out before so not sure what to expect. Any ideas anyone?

It just pulls straight up. Has it raised some and feel like its caught or is it still stuck to the block? It will come out

maybe a small pry bar do not use excessive pressure turn engine over until the rotor is pointing at the fire wall and mark the postion on some tape same for the vacuum canister on the valve cover this will make for easy installation

It looks like it is raised up a little and is stuck. I used all the strength i could muster and it wouldn't come up

 

dumb question did you remove the bolt and retainer?

missed that no reason for it to not lift out? maybe try turning the rotor while lifting?

yea that is what I thought. I did turn, well i say I turned it i turned the outer part, not the part where the cap goes. This engine has been in a really long time it seems and a lot of grease on it so I did put some penetrating oil on it tnight to see if that helps in the morning.

The inner shaft that the rotor mounts to will need to turn as you pull up on the outer housing. The gears on the cam and distributor mesh together in there. If you were able to pull up the outer housing slightly, it sounds like it is free of interference. Keep working on it, it will come out.

No the oil isn't old I change it regularly, but i don't know how often it was changed before i got it. It was used on a farm so not sure. but getting ready to try and see what i can do with it. I will update you all when i get done. Thanks for all the help.

Ok all after a little persuasion with a pair of Channel Locks I got the dizzy out. Something that concerns me though is that a lot of the parts were damaged, Like the metal piece was broken off of the cap, the pickup coil the magnet was in half and some of the plastic washers where the springs are right under the cap were broken. Not sure what caused all this to go on, but I got it all apart and am going to clean and replace needed parts and see what happens.

if there is any sideways movment in the shaft, top or bottom. i would replace the entire dizzy(distributor up here) if you marked placement of shaft should be an easy exchange Rob

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.

      Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
