I replaced both gaskets and tightened them bout as tight as I could get with a 1/4 drive ratchet and the waterpump seeps at the very top just a tiny bit as does the thermostat my mechanic suggested ditching the gaskets and using right stuff? What's the fix here?

 

I used 1/8" on both sides of the thermostat gasket, around the bolt holes in it too... No leaks.

 

The mounting surfaces should be sterile clean in order for any gasket/sealer to work......and since both are aluminum, the bolts should be just snug to avoid cracking the metal and cutting/crushing the gasket. After re-cleaning the mounting surfaces, try new gaskets with a thin film of RTV on both sides and just snug on the bolts.

 

Any tips on not loosing all the rtv tryin to get the waterpump in the proper place?

 

Put a thin film of RTV on the water pump and a thin film on the block. Slip 2 bolts thru the pump, place the gasket on the pump and carefully install the pump to the block. Run the bolts down finger tight then just snug with a wrench/socket.

 

Yeah what djb said ^^^^ works everytime
