Question about 1999 Pontiac Firebird

1 Answer

I have the crappy Fireturd intake manifold issue...possible blown engine

I have a 1999 pontiac firebird with the intake manifold issue. Replaced the radiator 2 years ago (filled with sludge)... about a month ago noticed the sludge was coming back, and noticed telltale signs that the head gasket might be leaking.
I let my car sit in the driveway for about a week, knowing that it had a manifold or head gasket leak, as I was losing anti-freeze and the last time I started it it was making a ticking noise when it first started up that would go away, I was assuming that was the water that might have been in the piston area. But I decided I better fix the gasket problem before it gets any worse, so
I was going to drive my car from my driveway to my garage so I could replace the intake manifold gasket and head gasket if necessary, However, after trying to start it I heard a Loud BOOM, immediatly shut the engine off, I'm currently crossing my fingers that when I get the spark plugs out that all cylinders have compression, I'm assuming that was the sound of hydrolock and the rod breaking, If its a blown rod, what used engine should I replace it with... there are several online ones...
Thanks for any help...

    How to remove the engine of 1999 Firebird

  • Anonymous Mar 19, 2014

    I was thinking maybe a intake manifold gasket, and hoping not a head gasket. While driving can occasionally smell fuel. Now car has sputtering, and lack of power with accell. I have not owned the car long. I can see brown sludge in my radiator, I am assuming is maybe oil. I need to know where to start to fix the issue, as I need to use this car on a daily basis. Any ideas? Car is a '96 Firebird, 3.8 ltr, 5 spd, 144k miles....

    heads have been replaced due to leakage at guides on 2 different cyls, 1 int - 1 exh. tech thought this was the fix. he then noticed intake manifold flexing down on start up and flexing back up on shutdown, replaced intake says it doesn't do that anymore but still has backfire sound from intake on shutdown.

It can be going out of the exhaust. Fill the radiator up to the neck of the filler. Warm up the engine and let it idle, leave the cap off the radiator and keep it topped up. Check for bubbles in the radiator.
if there are bubbles then you have a cylinder head leak.

Sounds to me like a cracked head and/or a blown head gasket. Is the car low on water in the radiator and if you live in an area that is cold do you have enough antifreeze in the car.

1999 Pontiac Grand Am with "lower intake leak"...What does this mean specifically? Would this mean the intake for the radiator, gasket, or valve?


Usually intake has to do with the induction system, as in intake manifold , The intake manifold can have several types of leaks, the intake can have a vacuum leak, oil leak, coolant leak or a combination of any of the before mentioned....hope this helps,
