#6 of 110 Intake Manifold Gasket
Apr 06, 2007 (7:39 pm)
My 2002 Malibu has 69k miles on it, and today I brought it into my dealer for an inspection prior to a 1500 mile road trip next month. Dealer calls me back and tells me there's oil in the coolant, and the culprit is the intake manifold gasket. WTF?? How does oil/coolant relate to the intake manifold? My son suspected this was BS, so we go down there to see for ourselves. The mechanic said it looked like someone recently poured oil into the coolant reservoir (hmmm, could it have been him looking for a fat commission?). So I raise a little stink, told the service manager this never happened to my Toyota or Honda, and would Chevy cover the cost, as it has only 69k miles? He goes off and thinks it over, punches some computer buttons, and says Chevy will cover it if I pay a $200 "deductible." Otherwise, with the 6.5 hours labor, parts, flushing, oil change, etc., it'd have been over $1100. What do you guys think of this problem? Ever even heard of it before?

I have a 2001 Malibu and at 50K miles I had to replace the intake manifold gasket. Now I have around 100K miles and guess what the same problem is happening again. I have spoken to GM and they have not offered any relief or taken responsibility even though I know GM issued an internal service bulletin about this very problem. So... I have joined a class action lawsuit against GM and perhaps something will be done.

#9 of 110 Engine swap wiring problem
Mar 11, 2007 (8:08 pm)
I have a 1999 malibu and am swaping out the bad engine with one I found from a 2000. The wiring connection for the injectors is different. Does anyone know if someone makes an adaptor for this? Mine has two plugs - one 8 prong plug and one 2 prong plug. The new engine has a single 12 prong plug. Please help!

Can you just put the old injectors in, I doubt you will find an adaptor.
You could try the dealer for a repair plug, but you would need to do a lot of splicing.

I have a 1972 Nova and a 1977 Malibu. I'm trying to still the engine and transmission from from the 1977 Malibu into the 1972 Nova. Does anyone know if the this swap will work? Also if it will work is there any modifications that must be done to the wiring, or anything? Or is it a plug and play swap?

Today I'm told that my 01 Malibu has the gasket problem and I have a big repair bill. Can you give my some info about the class action suit? (Canada) Thank you.

When I took my '97 Olds Cutlass GLS (same as later Malibu) 3.1 L some years ago to a local mechanic that was GM GoodWrench certified, he showed me a pile of gaskets that had been disolved by their long life orange coolant, and strongly advised changing to standard ethylene glycol green coolant. Heeded his advice, and the car has over 150k miles on it with no intake or head gasket problems. When both '05 and '06 Malibu's are out of warrantee, the same change over to "simple green" will happen to them also.

If you haven't finished by now and figured it out, I can say with experience that the swap will work. Depending on whether or not the '77 has the 5 wire distributor, you may want to use the one out of the '72 if it is electronic. Other than that, they are a simple swap out for the V-8 models. Be sure and swap the exhaust manifolds because the Nova pipe out pattern is typically different than the Malibu.
