Question about 1995 Buick LeSabre

1 Answer

I had leaking lower intake seal, pulled it into garage won't star

The lower intake seal was leaking antifreeze. The week before making that repair the radiator sprang a leak, I made it to work before I knew what the problem was. Put a new one on where it sat in the parking lot at work that evening. Drove it fine for about 9 days before pulling it into the garage to replace the lower intake gasket set. Got it all back together and it won't start. We have checked everything but the timing chain and gear. The ex thinks the nylon that coats the timing gear(or whatever it's called) got brittle when the radiator leaked and over the last week of driving, it has crumbled enough for it to get out of time. What do you think?

If the chain gear failed the distributor rotor will usually stutter as the engine is cranked, or, you will show extremely low compression on a comp test. Both are easy to do and I'd do that before continuing with other diagnosis. (also, a bad chain gear will often show up as engine cranking unusually fast)

Transmission rebuilt, leaking at o ring to radiator, now leaking antifreeze intake gasket

While it is possible, any seal could go at any time, I do not blame you for being suspicious. I would check the intake bolts for a loose one (better done before complaining about second leak - little to no chance for a re-tighten if done on purpose). Note: it is possible for a bolt to loosen on it's own. I also suggest taking the vehicle to another garage and explain the situation to them with a request to look for tampering. You might want to speak with the police before taking any further steps in case they wish a report filed.

Lower manifold leak 2004 chevy

If the lower (intake) manifold is leaking, which is very common, then you should either have an external antifreeze leak, or antifreeze into the oil. Oil will not go into the antifreeze. The coolant used in this car (DexCool) does, however, form an oily substance on the surface over time. I would recommend having the antifreeze flushed out, and the reservoir cleaned.

Hey Baptized,
You need to replace ALL the gaskets that seal coolant from ANYTHING... You may have a cracked head, cracked intake manifold,, or at worse a cracked block - between the coolant passages and the combustion chamber area...If you have a aluminum intake and cast iron heads.. this is a potential leak creator when the engine gets hot and cold quickly...make sure ALL the gasket surfaces are CLEAN.. and use:

DO NOT use silicone sealant - period!

I have antifreeze leaking from somewhere in the front. I think it could be the thermostat housing. the leak only happens when the engine is warm and it's not that much of a leak. just enough to have to...

The one definite thing you need to do is to run the engine 'till it begins to leak, turn it off and carefully examine everything and find the source. Obviously, I can't see it but the start of any repair involves identifying what needs to be replaced by looking. Antifreeze will run down to where it can drip off the car onto the ground. Make sure you find the actual source which most often is much higher up on the engine than the point where you actually see the drip. When hot, the coolant is under pressure so before attempting the actual repair wait for it to cool down or you can get burned.

Is it leaking oil or antifreeze?
If it's oil at this location ,it is most likely the seal on the sealed (not used) distributor hole plug.(an easy fix).
If it's antifreeze it will most likely be the gasket between the head and intake.A little work but not bad.You will have to pull the valve covers and the intake but the heads stay on.

My 2000 Park Avenue Ultra knocks when you first start it up, but goes away after it warms up. It is also leaking antifreeze. Do you know what may be wrong?

Late model GM cars are plagued with antifreeze leaks around the Upper Air Plenum gasket and also the Lower Intake Manifold gasket. This is brought on by Dex-cool antifreeze deteriorating the gasket materials. If the Lower Intake gasket is leaking, it may have contaminated your loil with antifreeze. If there is antifreeze in the oil it should show up on the dipstick as a gummy sludge. GM has issued Technical Service Bulletins to their dealerships concerning this issue. Check with your local dealership to see if they will repair it at no charge. There currently is no recall, so they probably won't. In that case, take it to a good garage and have it repaired. Don't wait too long. If the oil is contaminated, it will damage your engine from lack of lubrication.

My Chevy Malibu 1997 has a major problem with leaking in the coolant system. The coolant light comes on and stays on. We put prestone in the recovery system until its filled. The coolant light continue...

I'm guessing that the mechanic fixed a coolant leak around the gasket on the upper air plenum. The gasket leak was probably caused by Dexcool antifreeze deteriorating the gasket material. If that is the case, then the lower intake gasket is probably leaking too. If the mechanic refilled the cooling sysytem with DExcool antifreeze, then it probably destroyed the sealant he used to make the initial repair. I would have the car towed back to the mechanic to avoid any further damage from overheating. Have the mechanic remove the lower intake and check the gasket for leaks. DO NOT refill the cooling system with Dexcool. Use a compatible antifreeze that will work with aluminum engine parts.

2000 chevy impala ls - oil spray under hood inline with serpentine belt

You may have a lower intake manifold gasket leak (or a head gasket leak-slightly less probable) the lower intake can leak onto the serpentine belt and fling oil (and/or antifreeze). The lower intake manifold gasket is usually the culprit here. There is much information about changing it if you are inclined to do it yourself. If not, expect around 800 to 1200 to fix at dealer/mechanic. This is usually accompanied by (but not always) oil in the antifreeze, or antifreeze in the oil...
