That would be impossible. If the head gasket has failed than the only tru fix is to replace it. This would involve an extensive disassembly of the major engine components. There are stop leak products on the market that claim to fix these problems. I can assure you that these are band-aides. As we know they only cover the wound they do not heal it. The only way you could fix it without taking the engine apart is to replace the engine with a used or remanufactured engine. This would still involve the transfer of parts from one engaging to another and the removal and install of the engine itself. Let me know if you have any questions and I'll do my best to answer them. Thank you for using!

Can I repair a bad cylinder without taking apart the motor in a 2000 Monte Carlo?

Are you talking about compression readings? If so, and you only have 30 psi, engine is in serious state of disrepair. The cylinder head will have to be taken off to fix the problem-sounds like a stuck valve, a non sealing valve, or a blown head gasket. There's no way to get to it without removing the head.
Apparently you had a compression test done? If you had done or would do a leak down test of that cylinder, it would pinpoint the source of the problem-whether an intake or exhaust valve, or a head gasket, or piston or ring damage. With a leak down test, wherever the air is escaping from the cylinder points to the source: if for instance, air leaks out the exhaust pipe, you know it is the exhaust valve not sealing in that cylinder. If air leaks out the intake-it's the intake valve.
Air hissing from the oil dipstick tube would mean compression is being lost past the piston rings-going into the crankcase.

My 2000dhs is running hot. I replace water pump and thermostat. iI check the oil there is no water in it to indicate a broken head gasket. i was told about some type of heat sensor on side of the...

Yes, this is very common problem of the northstar platform. Head bolts aluminum thread inside the engine block stretching. Although Cadillac improved it in 2000 year model, it persisted on a lot of cars. You will not see any water in oil, at least for the first 5-6 thousand miles, but it will get worse and worse every time, so aventually you will. Engine will "drink" your coolant and no kind of coolant additives will fix that. Especially big coolant loss will be if you floor your gas a lot. On the freeway however you can go for an about 100 miles before engine will consume most of the coolant and overheats. You need to fix the block, cadillac calls the proces "time sert" - they drill bigger holes in the block, thread it and put inside inserts with outer and inner threads, were your original head bolts will go. Dealer going to charge you $5500 for that, and most mecanics will charge around $3200. That is why so many people selling their caddys cheap on ebay saying that there is a coolant leak somewere. I bought two caddys like that. Now I can fix that kind of problem easy. I bought all of those expensive tools for time serting. And by the way, something I learn the hard way, even if you are mecanic but never ever rebuilded northstar before expect lots of problems and difficulties. Very complicated hi tech engine with balanser shauft. Parts are expensive too, upper set of guskets will cost you about $320 and if you buy all the lower seals too than $500. Piston rings $220 and good luck finding it in autozone. I guess it is time for you to find out how are those used car dealer shues fit you :-)

Where is the head gaskets

This is not a good question to ask.....I take it that you must not be too mechanically offense. is this a v6? A head gasket is between the head(s) and the block. If a head gasket is bad (blown), then it is a very major job to replace. And hoping that your head is not cracked, which is sometimes possible. It is like tearing the engine apart, except for the crank and pistons (bottom engine) head gasket is on the top half of the engine. I would estimate that this job would cost you over $1000. without cost of parts. ???
