I have a main seal leak... What do you think is a fair price to repair? I have a quote for mid $900 range

Manual or auto trans ?

900 seems high but its not crazy high.

It seems high just to replace seal. Which can be done. If shop is going to replace seal, housing and oil pan gaskets maybe okay. It depends on local labor rates. I would shop around and know exactly what you are getting. The one piece rear main seals don't leak very often. Most leaks come from the top: rear edge of intake described as"China Wall" , oil switch, or valve covers. You may want second opinion. Oil dye and a black light can accurately show were leak is coming from.

Rear main seal replacement is a pretty serious job on a LT1....

Got to remove the trans and TQ converter or trans and clutch/FW assembly.

$900 sounds about right.

As stated make sure it is not the back of the intake manifold/block china rail leaking and then running down the back of the engine/trans..... LT1's are famous for this leak being mis-diagnosed as rear main seal. Fixing that back of the intake leak is a much easier and cheaper job.

I had the manifold seal replaced recently... What is the best way to make sure manifold seal is not leaking? Can I see that from the top rear view with a flashlight?... I'm thinking I should see a wet mess dripping down from somewhere?
Also, I recently had the valve cover seals done so I'm not thinking that's it.
