replaced all the Glows it starts right now , runs well ... also found a short in a wire , now all the gauges work to boot ! Thanks for all you guys help !
Glad to hear it. Also glad you caught it before all hope was lost.
My '90 6.2l has 285k miles. I just wish it had a turbo...
Probably better off it doesn't--a turbo would likely make a high mileage 6.2 more likely to spit the crank out or snap it,or increase blow by problems at the least..
Personally I think the turbos on 6.2's are over rated--the "gains" in power dont always add up...it adds a burden to all internal engine parts from increased heat and pressure,and the life expectancy goes down..I think these engines are better off left naturally aspirated..
I dont know how many miles are on the 6.2 in my pickup,but it sounds like a lot--its a lot noisier than the one in my Suburban with 156K on it..(that one sounds silent in comparison !)..
After reading online how many of these engines have broken the crank or blown head gaskets,and many ran "perfectly" till they went out with a bang due to the crank failing,or cracks in the main bearing webs decided to let loose suddenly,I've become rather apprehensive every time I go anywhere in my truck...(especially when the engine sounds like its already "loose"--hard to say if its "normal" diesel noise,or parts are worn and sloppy)..
I know not every one blows up--but it gives you an uneasy feeling,like you dont dare trust it far from home--but I'm paranoid that way regardless of what I'm driving,but more so in the diesel pickup..
--then I come here and read about guys who drove thousands of miles with zero issues..
..
You should sell it then.
Most broken cranks and mains can be traced to bad balancers. I know plenty of NA 6.2s with broken cranks and poofed head gaskets. A under powered 6.2 tied to a trailer with a soring egt is way worse than a little extra power applied to the internals.

These are the normal 6.2 stories. You don't hear them as often as the horror stories because they are boring and few people care to repeat them. I woke my K10 up from its winter hibernation a couple days ago. Turned the key, fired it up, and carved a bunch of ruts through 10" of snow. It was a blast. But not particularly noteworthy, as that's a fairly normal occurrence for such a rig. So that story didn't get posted (until now). People with problems, OTOH, are much more likely to post up because they are looking for answers and need input from others. So reading forums will give you a skewed perspective on how often these things actually break. You're hearing just the bad stories and none of the normal stories.

Some of them blow up at a young age, and some of them go 400,000 miles (or so I hear from @blazinzuk). Most of them live normal lives and last a normal amount of time. Unless you have some specific reason to think your engine is worse off than normal, you should expect normal life expectancy out of it (though we could bicker about exactly how long that is, as it has a wide range). That doesn't mean it will last forever, but you shouldn't be afraid to drive it down the street. Don't let the horror stories contaminate your expectations. I can find horror stories for any engine model out there. The 6.2 has fewer horror stories than a lot of the engines you pass on the street. You may be one of the lottery winners who does blow out a main bearing web, but most non-abusive 6.2 owners do not encounter this.
You've correctly identified the fears as a paranoia, but don't let that cripple you from getting out and doing things. Cars blow up, and yours will too, if you keep them long enough. But parking it in the shed and being afraid to use it can cause sitting-related issues to crop up. So giving into your fears may indeed cause them to come true.
IMO, most of the noise that a 6.2 generates is a function of exhaust piping. My glasspacked Suburban sounds quite a bit louder than my normally-piped K10. My M1009, with rotted out stock exhaust, is somewhere in between. I'd bet your K20 has a crummy exhaust if it's noticeably louder than your Suburban.
Yep my 6.2 as far as I can tell is a 400k plus mile motor.
I'm looking forward to pulling it and seeing what kind of shape its in.

Also it makes me laugh when guys call a turbo 6.2 a ticking time bomb. Pretty much every motor ever built is a ticking time bomb
It's just that it sounds like it'll grenade any minute,that gets my anxiety level up--also the vibrations a diesel makes,everything "buzzes" in the cab,kind of feels like the engine is bolted in with solid mounts--I realize that's the nature of any diesel,but its still nerve wracking..
I won't sell it,for one not worth much to anyone but me in its present condition,and I just hate selling things period--I don't like unhappy buyers returning with threats to sue,or beat my a$$,after they whipped the truck to death,which has happened before..
I tend to keep things till they are well used up,then part them out and scrap the rest..scrapyards dont want refunds or revenge..
..my pickup 6.2 makes most of its clatter from the front of the engine,probably the injector pump drive and timing chain,and it has some valve tappets that are noisy after every cold start that takes a good 5-10 minutes to fade away--the first few minutes after a cold start is the worst,it sounds "loose" .like a stone crusher..then after it warms up,everything expands some and quiets down some..
...while the Suburban has a "stock" dual exhaust and after I fire that up cold,the engine sounds much "tighter" and quieter than my pickup...
The only thing I hear is the fan,a squealy alternator belt for a few minutes,then its a lot quieter than the pickup...it also feels less powerful and responsive than my pickup too,and the drivers side bank will put out some blue smoke if you hold it at a fast idle...maybe the injector timing has been monkeyed with on the pickup,I never have looked to see if the marks are aligned..
A friend suggested I replace the fuel filter--its been on it a long time,he claims some diesels he's worked on quieted down a lot,after the filter was replaced..I'll probably do that soon...doubt it'll make any difference though..
The harmonic balancers look ok on both engines,they dont appear to be deteriorating or slipped..(but I haven't inspected them REAL close either)..
I do have glass pack duals on the pickup,but its not the exhaust note that worries me...the fact the pickup had been run with used oil for quite some time also likely did it no justice either..but it doesn't blow blue oil smoke,and it must have decent compression because it'll start good cold,even with a few dead glow plugs...(you can tell a few cylinders dont fire at first,then start kicking in)..
...weird thing is when I was adding used oil that likely had some synthetic mixed in, that was a lot thinner than 15W-40,it spun over in cold weather a lot faster,and if anything,ran quieter than it does now,with a fresh 15W-40 oil change...but the oil pressure went scary low in hot weather in drive at idle..now it'll maintain at least 25 at idle hot..
