Severe Starter Issues (like this is bad...)

My S10 is a 1995 with a 1996 V6 vortec that I threw an edelbrock intake and 500 cfm carb on.

here is the real kick in rump...It eats starters....literally destroys the solenoid.

When I watch it try to turn the motor over it whins n barely turns the motor then the aperture gear slips n makes a god awful metal on metal bang sound.

So when I get a new starter it is fine for a few starts then the problems reoccur.

Could this be an issue of the motor having too much compression for the starter and it not being able to turn the motor or am I missing something else.

I am just tired of replacing starters.

Did it do this before you installed the manifold and 500 cfm carb?

 

Too much timing?

 

Carb flooding the engine causing hard cranking?

It has never been started with anything other than the intake & carb. It shouldn't be flooding as I have checked for signs of that and the timing is only +3 Degrees according to the markings on the balancer, but I wouldn't understand how timing would effect the starter. Could you explain please??

No insult but are the starters being shimmed correctly when installed? Could be the starters are out of whack when engaging the flywheel. Have you done any other mods to the engine? What kinds of starters are you using, cheap rebuilds don't tend to last in my experience.

The starter has been shimmed correctly according to my friend who is a certified GM mechanic and no offence taken. There are no other mods to the engine and the starter was not a rebuild nor was it a high end starter...would you recommend a starter that is high performance/really good for 4.3L v6.

In the case of a starter, I'd definitely put some money into it everytime. Also if you've replaced the starter a lot, how is the flywheel teeth looking? It's possible your flywheel is getting grinded down (or worse flywheel is loose) and the new starters are helpful for a bit until the teeth on the starter wear down. I'd pull the starter and run the flywheel around and see what is going on, on the engine side. Also before putting on a new starter make sure it is for your exact engine. I don't remember the timeframe but for a while there was the a 4.3 Vortec and 4.3 non-Vortec. You may be getting the wrong parts and the starters is quite matching up to your engine.

Back my days of big high compression V8s, a lot of static timing advance made the engines really hard to crank. Pontiacs were notorious for this. There were even schemes to retard the timing until the engine started. I just made do (still do) with the correct high torque starter, the biggest battery and cables available. Sounds kind of cool actually.

      seat base height *lowering* (base 40/20/40 seat, 2026 1500 WT std cab)

      By bwiese · Posted

      Folks, Have a great new 2026 WT  (std cab, 2.7/4WD) w/base 40/20/40 mech adj bench "fake buckets"  (with lower and upper center console) heavy vinyl seats.  Overall the seats are very comfortable and the vinyl is heavy and appears less likely to 'split out'. Am very tall (6'5")  + a bad back/osteporosis/former hyperparathyroidism so ease/range of movement is a bit restricted.  The truck rides a bit high and I use a nerf step bar w/my left foot to step in, then I put right foot/leg in, drag my butt in  & get seated.  Worked fine in my 2018 RAM quadCab. But I end up dragging my butt over the left raised sidecushsion area of vinyl seat, and due to texture there's fair amount of traction on slide inward.  (ArmorAll didn't improve.) If the seat were even ~1/2" - 3/4" lower it'd be helpful, but base seats just have the forward/backward underseat bail and the side lever for tilt which really doesn't affect seat height.   I really don't want to 'de-puff' the left side sidecushion forming the  fake 'bucket'. I know one company sells 'seat elevator blocks':  but is there a simple way of lowering the height of the driver seat instead?   Thanks Bill W San Jose

      Travel Trailer 2024 2500 HD 6.6 Gas Engine ?

      By Tyler Gibbs · Posted

      The curb weight on a 1 ton crew cab long bed is around 7k lbs.  Now, I don't know where you went to school but 9k is not more than 2x 7k lbs. More than 2x 7k lbs would be 14k+.   With that said, obviously yes you're going to feel a 9k lb trailer when slowing down.  I already said, when accelerating.  When changing lanes?  No.  But if you look at the context of what was quoted, the original person said, "after a mile or two..." which means that would be after the accelerating portion and you're driving a generally steady pace.  Please do learn to read and comprehend.

      Like I've said before. Di and Carbon buildup is not that big of a concern. Engine had minimal buildup, and that engine was obviously not super well maintained. Do regular oil changes, and you're gtg as long as the rest of the truck lasts. Also, the High Pressure FP that people ****** about, but can't tell you why.  Now, I wish they'd trash the variable oil pump. No real world issues with them, but I'll gladly eat whatever miniscule MPG it's saving me in favor of more oil at all RPMs.    Curious to see his assessment of the 7.3 compared to the 6.6. I expect he'll praise the port inj, but from a structural standpoint, the 6.6 is as robust as any engine out there.    Not to take away from the 7.3. I feel it's equally as good as the 6.6.     As to heat on the rear cyls, I'd have to see numerous examples before I'd say it's an issue. Especially not knowing the history of that engine. For all is known, they could have blown a rad hose, and ran it hot, and the 2 rear cyls may be the first to get hot in a low coolant situation, but not be an issue aside from that.
