Well,I hate to say it but at this mileage anything can break! Believe me it happens with my '88 Corsica with over 227,000 miles on it!

You check this....that breaks,you check that...this breaks,see where I'm going here?

I would change out all the filters (fuel,air,oil,trans.,PCV valve) and fluilds (oil,trans,frt.& rr.diff,transfer case,brake,coolant) and also change the belts and hoses (thermostat too!),this would be a good start

You never know when a fuel pump is just going to die sometimes or when a water pump might start to leak or when a starter just isn't going to start!

You just have to fix some things as they break.

I second that! I had a 95 K3500 which started fizzing coolant at the back side of the intake manifold. Truck had 100K miles on it at that point.

 

Had the dealer replace the IM gasket, problem fixed.

 

Plus, had developed a strange 1 qt per 1000 miles oil consumption problem right around the same time. After the IM gasket replacement, no more abnormal oil consumption! I can't figure out why, but facts are facts. After the fix, the truck was back to 1 qt every 5000 miles, like it had been for most of its life.

It is funny you all say that about the 305/350. Back in '96 my'89 caprice did that, and the mechanic just thought it was so strange that the manifold was not warped, corroded (this comment sent me packing) etc... They wanted to charge me 500 bucks for a new manifold and gasket. Needless to say, $90.00 (oil change, coolant flush, and gasket set) and time, I did it myself.

 

That was my how I popped my cherry on major car repair. The only tricky things was remembering to torque down in the correct order, and retiming the beast. Oh yeah, and replacing the heater valve(they don't even use these anymore) that broke in the process.

      NEW TRUCK

      By PunchT37 · Posted

      Get the 5.3. I`m not a Ford guy.😉   I think these L84`s are less problematic than the L83`s. Certainly less than the L87.

      NEW TRUCK

      By PUSSLEGUT · Posted

      I have finally paid off my mortgage and can now purchase a new truck. I would greatly appreciate any opinions on the purchase of a new 2026 GMC Denali 5.3L or 6.2L with the Denali reserve package. I am not interested in the 3.0L.  Or should I go buy a Ford?   Thank, John

      One of the few things I enjoyed about my time in the midwest was taking off on weekend drives. Unlike home, where we are boxed in by mountains and water, those rules don't apply to the inland plains. Roads connect and sprawl everywhere. While Minnesota is flat, it's not completely featureless and there are fast moving rural roads with curves and slight elevation changes. I used to relish heading out in a particular direction with no set destination, no curfew, and weaving through little townships, wherever the roads would take me. Along farms, lakes, or through the deciduous trees... It was beautiful in its own way, and the seasons were so distinct there. Fall drives yielded amazing shows of color and contrast. Summer drives rewarded with the and amber evening glow of the prairie (and lots of juicy bugs).    I do a lot of that here in my home state too. But it's much less mysterious/intriguing. I've traveled most roads in the region, and every road that's fun to drive within a good radius of my house. But every drive, even on the same old roads, is still enjoyable. I know where I can lean hard into the throttle or really throw the car into a curve. There are exercise loops for when I just need to keep certain cars limber, and much longer routes to settle in and enjoy a drive and put some miles on. All the mountains and water make for some really awesome roads for spirited driving. But not all my driving is spirited, for example, that's not really enjoyable in my pickup or this Blazer (that's still here...).   Sometimes a good drive is followed by a ritualistic wash before tucking the car away...

      L8S For 2027

      By C/K Man · Posted

      'GMAuthority' is reporting the 2027 HD's will have the L8S 6.6L gasoline V-8.  There was some talk here about the L8S awhile back.  Not sure what changes it will have now as it seems the 2027 emissions regulations have changed from what was originally proposed.  The big question will be is L8S just a stopgap for the last 2 years of the current T1 HD platform or will it carry forward to the next generation 2029 T1-2 HD's?    I assume the L8S will still be a Gen. V engine.

      New Duramax rumor?

      New engines will still be using DEF. You just won't have the limp modes occurring when you run out of DEF now.
