Was the low oil pressure happening before you replaced the head gaskets ? The oil passages between the block and heads could be covered over.

SOURCE: Gents, i have a colt

hi well sorry to say this sounds like you have not cured your head problem, if you feel the top and bottom hoses to the radiator are they rock solid after a short time? if so, this means that the head is still not right and either there is a crack in the block causing it or the cylinder head that you replaced it with needs skimming, this will make no difference removing the thermostat if the head gasket is still not right...hope this helps

Overheating


You have a head gasket problem with the engine generating abnormal pressure, and sending all the antifreeze to the reservoir, thereby leaving the engine running dry; it is dangerous for the water pump to operate with no water.
Drill 3 11/64 or 3/16" holes in the thermostat side facing the engine, making sure not to touch the opening mechanism; this will keep antifreeze always running thereby, compensating for the abnormal pressure regenated by head gasket leak(s).
Your thermostat was never your problem.
In cold weather, 5 degress celsius or under, the thermostat takes longer to open and more antifreeze will be sent to the reservoir leading to an overheating.. Partially cover the radiator with a sheet metal piece to make the thermostat open faster and stay open, as the antifreeze is not being cold that much by cold air. You're fooling the cooling system into warm weather driving.
Don't waste your money buying radiator stop leak or liquids to repair head gaskets; this will only corrode and make your radiator to eventually leak.

Sorry to say the head gasket is still shot, and you probably have cracked the cylinder head too.
The excessive pressure in the radiator and the overheating is compression going from the cylinders to the cooling system. You may not be leaking coolant into the oil as fast as you were, but its still letting compression into the radiator.

How do i fix the low oil pressure issue im having. When i drive, the temp stays normal at 210 but when i idle, it goes up to 260. I was told the oil pressure is low and i needed a new engine


Your engine is overheating, which isn't directly related to oil pressure. I would take the S10 to a reputable/trusted mechanic and have him perform the following tests.
Compression Test Leak Down Test Coolant System Pressure Test Inspect Oil for Moisture (you can do this one, remove the dipstick, does the oil on it look like milk? If it looks like milk it means there is water/coolant in the oil, a sign of a blown head gasket. However not all head gaskets dump coolant into the oil when they blow) Inspect Clutch Fan for proper operation
The mechanic will know what those mean, It sounds like your head gaskets may be blown, which is why the engine would be overheating. Also if the Clutch Fan isn't working properly, it won't pull enough air through the radiator to keep the engine cool at an idle or while sitting still.
If the Head Gaskets are blown, it doesn't necessarily mean you need a new engine.
One other thing to note, when an engine overheats, the oil breaks down and no longer works as good as it used to.

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.
