    Transfer case

    A friend had a 454 in a square body Blazer with the 203 full time transfer case. He would kick the transfer case into low lock and drag race off the stop lights. If the chain held, there was nothing that could beat it off the line. If the chain didn't hold, he coasted to the side of the road and...

    Finally have this girl home, now what?

    I brought home a 90 R1500 GMC which spent it's first 20 years in a heated garage and done funeral duty. The body is perfect. It had two dead misses and needed head gaskets. The windshield, headliner, radiator, alternator, water pump, heater core and fuel pump have been replaced. I also had a...

    Leaking head gasket?

    These used a steel shim head gasket so retorquing the head would not hurt anything. Getting at the lower row of bolts under the exhaust manifold will be very tough though. The oil pressure exceeds the coolant pressure so you can now have oil in the coolant. When engine is off, you should be able...

    How do you feel about this?

    Then it is a garbage picture as the bottom of the lifter should be bright and shiny. That looks dull, black as if it has not touched the cam.

    1986 C10- Is it reliable enough for a daily driver?

    We drive a 90 4x2 Suburban as a daily driver. With the 7004R. 157,000 miles with a new engine at 110,000. It spent the first 25 years, mostly in a heated garage, as a mover for a funeral home. Zero rust and am always getting complements on how nice it looks. I overhauled the engine, just put a...

    How do you feel about this?

    That lifter in the picture is totally junk. It needs a new cam and lifters.

    Best aftermarket antenna option

    My 1990 Suburban came with the fender antenna and not the windshield one. I am kind of in the middle of nowhere and this antenna works great. The oem radio was junk so I replaced with a Honda Civic one that works perfect. Square body radios were well known for dropping channels.

    You do know that turning the light switch left/right makes the dash lights brighter or dimmer?

    Parts suppliers, apples to apples

    The manager of the local O'Reilly's just resigned to go to work for a local manufacturer. No nights, weekends, holidays with more money and better benefits. I hate to lose him but I don't blame him for the move. There is no one else in the store that I trust. It is sad!

    08 Cobalt

    Dorman has turned into a Chineseum graveyard too. They are using cheap overseas parts instead of the quality known for years ago. If Dorman makes it, there was a problem with the original but they are no longer the fix they used to be.

    Air Conditioning leak checking / finding information sharing thread

    This is very simple. If you want to run it, then do. If you don't want to run it, then don't.

    Heat temp gun/correct temp sensor/etc.

    Buy the sender for the 250 I6. The sender should match the truck and not the engine.

    Anyone who doesnt have a service manual read this.

    I am fortunate to be able to write those cheap manuals, only better. I still may pull a book once in awhile, especially for torques. It is no shame. If you are not sure, look it up. When you get to the point when you know most of it, them your body starts to revolt. Wrench and enjoy the results.

    Bed prep if getting spray in liner???

    Nothing will stick to oil, grease or silicone. The metal must be clean.

    How should I solve this starter problem

    Percussion maintenance may free a stuck brush with no troubles ever again. Battery cables are rarely looked at but should be. The resistance test tells it all. Do the voltage drop test or look at the length of the cable and ends with a temp gun after starting.

    Air Conditioning leak checking / finding information sharing thread

    I have found that replacing both Schrader valves in the high and low service ports can help a lot. Those can leak a lot and can easily be changed. I am using mostly dye in my units. It seems to work the best but then I use the soapy water after zeroed in on where the leak is.

    6.2 years to avoid?

    I never had torque to yield head bolts. Mainly used ARP studs.

    Dual tank diesel, where to put fuel pump?

    My 82 6.2 had a lift pump on the engine that worked well for 1/4 million miles. I modified the fuel gauges so I could see both tanks at all times but the switch still changed tank left or right. I ran pure #1 in one tank and premium #2 in the other in the winter. I gets ball bustin cold here.

    1978 K20 Gas Gauge

    99.9% of the time the problem is the sender in the tank or wiring. Virtually never is the gauge bad.

    Water pump questions

    A lack of a thermostat will cause overheating. The water circulates so fast it does not have time to pickup the heat and carry it away. We are in cold winter country and run 195 thermostats year around. An engine must be up to temperature to be efficient and to run right.

    6.2 years to avoid?

    Replace the head gaskets now. Drive it 1,000 miles and re-torque the head gaskets. You will be amazed at how much you turn these bolts. Then drive it 5,000 miles and do it again. Keep doing this until you get no additional movement in the bolts. Now, it will run a long, long, time. I have taken...

    How much more power can a 5.3L make without hurting road manners or gas mileage?

    Cold air intakes are great but must be done right. The usual cheap ones hurt power and mileage as they suck in hot under hood air instead of getting it from the outer fender. Make sure they get their air from outside the engine bay or you are paying to hurt your performance.

    Torque converter 700r4 and TH400

    The 29 mpg was not normal. But it ran consistently at 20 mpg unless it was ball busting cold and running on pure #1.
