1997 Chevy Tahoe you took it to a mechanic and was told that the number 6 cylinder is getting no compression and that you need a new engine Can this problem be fixed?
It would largely depend on why #6 has no compression. It could be a minor repair or it could be a major repair. If it is a major repair and the engine has high mileage it would be wise to replace the engine only if the vehicle is worth saving.
What are the symptoms car might need new cam belt?
If your cambelt teeth have deteriorated, your engine may have been damaged internally. When the engine is operated using the starter motor then engine may not turn at all, or will turn over quicker than normal because no compression pressure is being built up. Remove the spark plugs and do a compression test, if no compression then the cylinder head may need to be removed for repair. Recommend were any doubt exists that a garage is contacted for further advice.
What is the compression on each cylinder on a 5.7 liter motor?
A new engine would have 150 LBS or more per cylinder. A used engine that runs real good and that has plenty of power should have at least 140 LBS. per cylinder. If there is more then a 15 LB. difference in any cylinder then you will have a rough idle and maybe an engine miss at a idle. That means there is an internal engine problem.
Should you have low compression after a head gasket change?
No, quite the opposite- the idea of gaskets is to ensure that an engine gives HIGH compression. If your car has just had a cylinder head gasket change and you are STILL getting low compression, then this suggests that the problem lies with the cylinder head itself- it may be cracked. Unfortunately there's no effective repair for this, the only solution is to get a new cylinder head I'm afraid.

What causes no compression to just one cylinder 5 Got a 98 Explorer that has fuel and spark but no start Tested compression by hand and 5 has NO compression Reasons why Repairable?
bad valve, bad rings or head gasket. need to do a leakdown test and see where the cylinder is leaking. do a copression test with adding a tablespoon of oil in the plug hole. if you get some compression, it's rings. have same problem with 5.0 in f150. mine bad rings on one cylinder. probable cause would have started with a bad injector leaking fuel and washing oil from the cylinder. then on restart that bore would not be lubed causing premature ring wear. at 150k, time for a new engine.
