If pressure builds up in the cooling system as soon as you start the engine, you have a problem. If you're leaking coolant from the oil into the crankcase, you have a problem. If you're leaking oil into the cooling system, you have a problem. If you have low compression on two adjacent cylinders, you have a problem.
Unfortunately, you can't know WHAT the problem is until you remove the head. All of the above problems could be caused by a warped head that resulted in a blown head gasket. All of the above problems can be caused by a CRACKED head that was caused by overheating.
Most of the above problems can be caused by a cracked block that was caused by overheating.
Most competent mechanics should be able to figure it out. Just find someone who has been around for a while and who has a good reputation. That's a job that can only be done locally.
Not likely. In fact, the backyard mechanics' test for a blown head gasket is to drip some oil from the dipstick onto the (hot) manifold. If it bubbles, there's water in the crankcase. Another sign is white smoke in the exhaust.
Because the head gasket is blown.
No it will not. The only thing that will fix a blown head gasket is to replace the gasket.
what are you asking here? PLease be more specific ...like - how do I know if my head gasket is blown, or what do I do about a blown head gasket ......
Sure it will start with a blown head gasket. But, if you continue to run this engine with a blown head gasket you will destroy the engine.
There are several possible indications of a blown head gasket: If the head gasket is blown between adjacent cylinders there will be poor or no compression in either cylinder. Poor compression in any cylinder can be caused by a blown head gasket. That condition can also be caused by a burned valve or piston. Coolant in the crank case can be caused by a blown head gasket. Compression in the coolant can be caused by a blown head gasket. An engine with a blown head gasket usually loses performance and runs poorly or not at all.
Yes, I blown head gasket will definitely effect the emissions.
With a blown head gasket the engine will still run, poorly with issues, but run. A blown engine will not continue to run from that moment on.
No, a normal tune up cannot cause a blown head gasket. A blown head gasket normally is caused by an engine overheating or by a defect in the gasket or head. If it happened right after a tune-up that is just a coincidence.
How much am I looking at for a blown head gasket on a 545.i bmw 2005
No, the only permanent fix for a blown head gasket is to replace it.
You cannot repair a blown head gasket, you must remove the heads and replace the gasket.
