Hey guy i bought a LT1 out of a 96 impala ss. It has a cold air intake that came with it that cost 350 bucks i looked it up! I start takeing some of the stuff off that i didnt need or want. Well what i found was new gaskets on the water pump then the timing cover? and also the oil pan? Do you think it was rebuilt? Cam swap mabey? Rebuilt? Give me ur guess!!!
thanks

Well, considering these motors leaked oil like crazy, I would say it probably just had a new gasket set put on it.

 

Ya mabey i just seen that the timming cover was taken off and was hopen for a cam swap lol.

i would guess that a cam would be a possibility youll just have to find out when you fire it up.

 

Just wondering if it is a aftermarket cam and if i take the timing cover off will i be able to tell? Will it have a name on the end of the cam?

Well took off the valve cover to see if their was something after market. It dosent look like it but new gaskets.

look all factory even the gaskets

 

The most notorious leak on the LT1 engines was at the rear china wall of the intake manifold. Take off the intake and reseal it all around... new gaskets, and just use a HEAVY bead of silicone on the front and rear china walls. Don't use the rubber gaskets. The back of the intake is the most problematic leak spot. Other than that, its the generic SBC places... rear main seal, and valve cover gaskets.

Timing cover on the LT1 is a heavy cast aluminum peice, so it usually won't leak, but the crank and Opti seals on the timing cover can. You can still get those two seals from GM, which would be a wise thing to do. Don't get those seals anywhere else, they WILL leak if you use the aftermarket seals instead of the GM ones.... I spend 10 hours replacing them, only to have them leak just as bad with the new seals. Put GM ones in - still dry as a bone.
