Oil Pan Gasket Reusable?
Ladies and Gents, After looking over the archives, I will ask a more specific question. Does anyone know if the 94 LT1 Oil Pan Gasket is Reusable? I have a front timing cover leak (I think) and it seems that to replace it, you should lower down the oil pan a bit to facilitate in the installation. I have read its possible to do that w/o lowering the pan, but its tough.
I would just change the oil pan gasket too, but since its not leaking, why go through the trouble.
Thanks

Trading Leaks
If you break the seal on the pan gasket you will end up with a pan leak even if you fix the timeing cover leak. 
Go ahead be a big spender and buy a pan gasket 
Besides if you have gone to the trouble to remove the timeing cover and loosen the pan you might as well finish the job

Front of the intake manifold (the RTV used to seal each end of the intake to the block fails over time)
Water pump driveshaft seal (located in the timing chain cover)
Optispark seal (located in the timing chain cover)
Crankshaft front seal (located in the timing chain cover)
None of the above leak locations require you to remove the timing chain cover as all can be R&R'd with it bolted in place.
If you still feel the need to remove the timing cover, then yes, the oil pan gasket should be replaced as well.

Its Probably not the cover gasket itself. Also When I did my head/cam swap I had my cam a tooth off so I had to tear it all apart again and I re used my oil pan gasket cause I thought it would be fine since it only had a few hours on it. Wrong, I have a oil leak from a few spots of the pan now!

Never reuse an oil ban gasket...
This is a cheap item and should not be reused. You are asking for a leak sometime down the road if you do. Clean the entire area, and change the gasket. Just my .02.

A highly respected GM mechanic told me the pan gaskets on a LT1 are reusable.
I had my pan off twice, I reused it once and it didn't leak.
But, if you aren't going to sleep at night, it isn't worth the few dollars it takes to replace it.
