More of a mechanics job. Going internal on this job and very easy to mess something up. But if you want to try it, you have to remove everything from top of motor and get down to head gaskets. just flat pieces of metal around where your spark plugs go in. cheap part just expensive labor.

SOURCE: blown head gasket

I would change both, as well as use new head bolts. Make sure your heads are not warped or cracked, especially the one that is leaking. There may not be any need to change the head if it is not cracked. These are prone to blowing a gasket especially after 150K miles or so. It will not cost a huge additional amount to change both head gaskets since the engine will have to be disassembled down to the heads anyway. Hope this helps you, Rick

SOURCE: lower intake manifold gasket leaking 02 Olds Silhouette

This is basicly a very time consuming job rather than a physically hard one to complete. In order to replace the gasket you must remove the intake plenum,throttle body, and misc. vacuum hoses. The wiring harness connections must also be disconnected. Finally the intake manifold is exposed. The bolts holding the manifold to the block are removed exposing the leaking gasket. After removing the push rods and placing them in the correct order to be replaced the gasket and sealants can be removed. Finally replace everything in reverse order. Be sure to consult a GM manual for correct bolt torch specs. The correct specs for the manifold bolts usually come with the gasket. Make sure to change your oil a few times after this job in case any coolant entered the block. Also,change the thermostat and the oil seal on the distributor half shaft cap while you have everything off. Good Luck

SOURCE: how much will it cost for me to get blown head

Never have seen blown headgaskets on a 3800 engine. Buick dealer parts guy over 20 years. You need a new upper intake manifold as it has leaked coolant into the combustion chamber. Also new plugs as you will have to remove them to get the coolant out. Common problem .

Just did the head gasket on a 02 olds silhouette and there is still oil in the coolant could it be the oil cooler leaking into the radiator or is there still a problem with the head gasket

the head gasket is fine you can check this by watching the radiator and oil levels if they dont move at all then there is still oil from the previous blown head gasket in cooling system they do make a supper strong cooling system cleaner for that type of stuff its made by prestone and works really good you might have to use it a few times.

My 02 Oldsmobile Silhouette is over heating what could be the problem

Overheating problems usually warrant some troubleshooting. First, check your antifreeze level. If it's low, replace it, run it for a couple of minutes with your heater on, then recheck it. Next, your thermostat could be stuck. For about 30 minutes worth of work, and about $10 of parts, you can do this replacement yourself. This will usually give you the symptoms of having one coolant hose being hot and the other cool, if it's the thermostat that's stuck closed. The next place to look is the water pump. There aren't too many reliable ways of testing one of these at home, so it's pretty much a replace and pray, because if it isn't, then it's something more serious like a blown head gasket or a cracked head. These last two can disclose their presence by evidence of oil or antifreeze leakage, or white smoke when you first start up your vehicle in the morning, but will not always do this.

2000 oldsmobile Silhouette engine over heating and oil mixing in engine coolant

These two problems are related, your engine is overheating because there isn't enough coolant to dissipate the heat. There are three main causes for coolant in the engine oil:

1. Cracked head
2. Blown head or intake gasket
3. Cracked block.

The gaskets are an easy and relatively cheap fix, the head replacemnet isn't to difficult but will run you more than the gaskets. If the block is cracked (pretty rare) you'll need a new motor because it's going to comletelyu fail sooner or later.

Vehicle is overheating...2000 oldsmobile silhouette

It's possible you have a blown head gasket. In that case, the heater core which is above the engine fills with exhaust and stops working. To verify this condition, check exhaust for excessive white smoke. If leak is still small, it's possible you won't see much. In that case have a shop check the radiator for hydrocarbons (exhaust). If the test shows any in cooling system, you definitely have a head gasket problem.
I'd also check the thermostat. Sometimes it can give similar symptom but more often than not this will trace back to the hg.
