I own a 1997 Camaro SS. Standard Transmission. I

clutch pedals are suposed to go all the way to the floor , you sure you dont mean brake pedal (cus thats bad ! ) clutches should travel all the way to floor and release the "grab" of the engine about 2/3 down , this way they are more smoothly allowing shifting thru the gears and not jerking as you shift thru the gears , if clutch pedal does not start to "grab" the engines power by 2/3 off the floor and fully "grab"its power all the way up(slipping) ,and you have a hydraulic clutch (96's do) then the clutch disk may require replacement or there is a oil leak in the clutch/master/slave cylinder , look for small oil leaks from under car in area of foot pedals
clutches should be replaced as an assembly that includes , disk ,pressure plate, throwout bearing , with engine side clutch plate magnafluxed for heat cracks and any hydraulic oil leaks replaced or repaired

Is it engine oil or transmission fluid? Is it driven often or does it sit in the garage? If engine oil, then possibly the rear seal is leaking into the bellhousing as you drive and then draining on the floor after you stop. If ****** fluid, then possibly front seal on ****** is leaking. If car sits for long periods of time the input shaft seal can allow fluid to leak past the shaft. This usually will fix itself when driven. Can't promise it will fix itself permanently. Will not be an easy fix if either seal needs replacing (or cheap).

valve cover gasket may be leaking

Water leaking from between the engine and transmission can only come from one place...there are two welch plugs (freeze plugs), located on either side of the rear cam plug. They rust out and leak. Your transmission needs to be removed to get to them. Sealers will not seal either.
Though they last a pretty long time, I always replace them with brass/bronze ones made for marine engines.Those will outlast the engine!!!
Make absolutely that nothing above the bellhousing is leaking before you do the job....it's too much work to do for no reason!!!

Mounts generally last a long time as long as the rubber portion is not exposed to oil. If there is oil coating the transmission and mount, you may want to try to find the source of the oil leak.

I don't know what engine is in the Z-28 package, but I had a '93 Lumina (3.1L V6) that leaked oil badly from the plate the blocked off the hole where the distributor used to be. (Sometime before '93, they eliminated the distributor and went to coil packs.) Replacing the gasket under this plate solved my problem.

Yes you have sup a bearing thats why the pressuer is high, if you keep running it you will destroy the cam or crank. orkill the pump.

Oil leaks can come from any where. Search for information on tracer dyes on-line. If its from the radiator area and the oil appears red its transmission oil. In most cars there is an area in the radiator for cooling the transmission oil. Try replacing tightning but not over-tightning the clamps in the two small hoses connected to the radiator.

First, do you see oil leaking on your driveway? Have you looked under the car and checked to see if any oil is dripping?A rear main seal will drip down the front cover plate of the transmission sometimes from the inside, appearing like a front seal leak on your transmission but the oil will not be red fluid you would expect if that were the case. I would not worry about rear main unless you see a leak there. Look your entire engine over and check for leaks everywhere. Several small leaks can add up to an overall large oil loss. Correct the larger ones first.
Generally all seals will last far longer if you change your oil frequently using a good quality lubricant. If you are loosing some oil, use one of the oils made for high mile engines. I suggest you use a mild additive like marvel oil 1pint with every oil change...it removes sludge, carbon and varnish buildup without the drawback of knocking it loose all at once, where it could plug up your oil pump screen. (it also smells good) Change oil every 3000 miles for the first three or four intervals, then consider using a good synthetic oil. Synthetics far outperform any other lubricant in every area! Avoid overheating your engine...overheating does more damage to seals than any single other item...When seals get very hot they harden up, crack and fail.
Good luck with your car!!!

you might want to start by taking it to autozone and see if you have any computer codes stored

Make sure it is the oil pan gasket, it is rare they leak, more likely the oil is comming from up top and drainning down on to the pan (since it is lowest point on the engine), have the engine cleaned of oil and then decide where the oil is comming from, if you find it is just a small leak don't worry about it.
