hi everyone,

have a coolant leak that has persisted for some time now. coming from thermostat housing. have replaced thermostat around 2 months ago, along with sealing it good. it was ok for about a month, now its started again.
i can only think of 1 possiblity, that the lower edelbrock manifold where the thermostat housing joins to might not be 100% flat, will it need to be machined? any thoughts on price?

also rang dynomotive to ask about fitting 77mm maf & 24's plus retune of unichip. $330 all up. any thoughts on this price?

thanks
james

the thermo housing can be checked with a feeler gauges,if even its flat,use hard flat sanding block and carefully sand the top rotating the direction your sanding,this will get you very flat and seal.use a marker to colour the top first,this will show you when its flat,do the same to the housing cover,gasket and sealer will work.
