The blazer too?

 

I have a 1996 GMC 2500 p/u that I just replaced the intake manifold gasket and the water pump on. I finally got it time and dialed in yesterday. Today my wife tells me her blazer is leaking. I go out and find the same d**n thing that I saw on my truck.

 

 

Looks like a leaking intake manifold. It is a 1996 Chev s-10 blazer. It is 2 wheel drive and has the 4.3 liter v-6. I've got coolant dripping from underneath the engine. It is leaking in front and in back. My water pump has weap holes on the top and the bottom. Both are bone dry. I cannot see any hoses leaking at all.

 

For all you experts....... IS YOUR MONEY ON THE INTAKE MANIFOLD OR SHOULD I LOOK AT SOMETHING ELSE TOO? This was a terribly common problem on my truck which almost made it seem obvious. Does this motor suffer from the same idisynchracy?

 

ALSO If I do have to replace the intake manifold gaskets do I need upper and lower gaskets or are they the same set?

Okay, now I don't believe this. The Blazer is done and is still leaking....a lot....

I'm now thinking either a soft plug at the back of the engine or a head gasket. I had a heater core go out and then another went out 11 mos later. The mechanic told me the cause was electrolysis. Now I'm wondering if this same "electrolysis" has coroded a soft plug.

 

I don't know what to do now other than maybe have a shop do a pressure test to locate the leak. Any ideas? It's coming out so fast that I can't even think about driving it.....

      Do you remember that Harley Davidson was more successful (solvent) when it produced about 60% of the market demand (by design) and forced wait times of up to three years? Even when your turn came around it was, "Take what we are giving you or move to the back of the line and start over". HUGE markup's were 'normalized' and dealer killed. 40% markup and no floor plan? What's not to love? Greed will kill them yet. They have surplus production and customer base is tanking. And still they think nosebleed pricing will work.

      The engine was done as part of the 6.2 recall?   You'd have to see if your VIN also has the 6.2 engine special coverage on it.  Coverage number is N252494003.  If you have this, your engine is covered under this and NOT the GM replacement part engine warranty which is 3yr/100k from the date of install.  The 3yr/100k mi warranty is in effect for non warranty purchases.     This is not any different if it was replaced under warranty without a recall or special coverage.  So if you had a 5.3 and it popped at 3 years in at 50,000mi during the 5yr/60k powertrain, the replacement engine would not get the 3yr/100k, and instead gets the remainder of the 5yr/60k as coverage.     So N252494003 gives 10 years or 150,000mi of coverage, which ever comes first, starting at the vehicle in service date.  So if your in service date is 01/01/2022, N252494003 gives you special coverage of the engine until 01/01/2032 or 150,000mi, whichever comes first.  So if your start date was 01/01/2022, you'd have left 5 years and 4 months (lets round to august 1st), or 62,000mi left of coverage.   So you need to know your in service date to know how much coverage is left.

      Injector update

      By CamGTP · Posted

      Okiee dokie there bud, way to take things to the extreme.   I guess you missed the whole point and take things way to serious. I installed different EV6 style injectors that just so happen to be larger in my car running the same LQ4 engine and with a better spray pattern than the stock style injectors and I noticed no difference in the idle quality. Kinda was my round about way of saying that even if you put the same size but better style injectors in your truck, you will likely see the same thing.    I'm sure you're great to have conversations with in person if that's how you act through a keyboard. One little things sets you off and now I guess my dick is all up in your face.

      I can't believe that could possibly be the case. It should be 36mo/100k miles from installation. Then again, it also seems like since a dealership installed it, it'd all be in the system and you wouldn't need to worry about registering, either. Shows you what I know. 😄 Hope this one outlives the warranty!
