Exaust intake leaking


It's exhaust manifold. There are two manifolds, the intake manifold in the valley between the cylinder heads, and the exhaust manifolds, one on each side of a v figured engine.

And, yes, a leak in the exhaust or the intake will make it run lean. If the leak is close to the engine, it can do harm to the valves, too. There is a gasket between the exhaust manifold and the engine block. Likewise, there is an intake manifold gasket between the intake manifold and the block.

When I put water in my 97 Tahoe it starts leaking heavily from the caddilac converter and around the muffler and exhaust pipe... What is this a sign of cracked head? Blown head cracked block? Intake...


Sounds like more water than can get out a crack. Check if you have a frost plug on the block has come loose and leaking. There will be about 3 on each side of the engine block, located just below where the exhaust manifold mounts to the block. It's a pretty easy repair, provided there is enough room to work where it is located. Sometimes a smaller such plug will be found on the rear of the engine. The coolant must be leaking externally and running and dripping off your exhaust .

I am losing engine coolant somewhere internaly. Truck is running hot. And my heater is not heating interior of truck


Check for external leaks first then check the engine dipstick to see if engine oil is milky looking. If so the coolant is leaking into the crankcase. If dipstick looks okay it could be leaking at the intake manifold. If it is leaking at the manifold coolant can be drawn into the cylinders and go out the exhaust. Other possibility is blown head gasket, cracked cylinder head or cracked engine block. The reason the heater is not working may be that the level of coolant in the system is not high enough to supply the heater core with warm coolant. Could also have air in the system. Internal coolant leaks will usually not get any better, only worse.

Coolant and water leaks from left side of engine.


Sounds Like you blew a freeze plug in the side of the block.. Check and if so replace. Not very hard to do. Looks like a circle in the side of the block. There will be a few of them..

How to replace the water pump on 1993 oldsmoblie achieva.


2.4 enigine is the harder of the 3 enignes. it will need a timing chain to be removed and a coolant tube in the back of the engine to be removed. this job on the book calls for almost 7 hours.

if its 3.3 or 3100 its alot easier.

3100 is just 4 10mm pulley bolts and 5 or 6 small 8mm water pump bolts.

3.3 is alittle more work, but same concept as 3100 engine. more owkr only cause its in a tighter area.

good luck,
michael
