Which holes on 350 heads are water jackets and need sealer?
All the head bolts need sealer.
Do the water pump bolts go through the water jacket on a 1979 Chevy 350 when removing bolts water pours out of one of the bolts hole.?
The Edelbrock head have extra holes that connect to the main water passages. I believe the steam holes help prevent any sort of vapor locking in the water jackets surrounding the cyllinder sleeve. Must allow the steam to escape up to the cyllinder heads. Apparantly older 289 and 302's didn't have these. Just don't break off the drill bit like I did!
Edelbrock manifold water jackets on front trickflow heads have front and rear will this warp the heads?
a welsh plug is a plug in the side of the block and the heads. these fill the holes left after casting.they actually allow the sand to be removed that is used during casting so as you have a hollow block which allows for the water jackets. in the USA these welsh plugs are called freeze plugs. they really do not stop the coolant from damaging the block if coolant freezes they are specifically to…
You have 390 ford every gasket you tryed blocks off the water inlet on the front of the block which the block has and the gasket do not provide for what gives?
The circulation of coolant flows from the water pump thru each side of the block towards the rear of block then up into the rear of the heads, then forward thru the heads and up into the intake manifold and out the thermostat opening. The holes in front are blocked to force the coolant out the holes in back of the block into heads.
Water jackets are the hollowed out spaces in the engine block and head through which the coolant flows. In water jackets, waste heat generated by the engine is picked up by the coolant. After flowing through the water jackets, water flows through the radiator. The radiator is basically a heat exchanger which, through a system of tubes and fins, transfers this waste heat from the coolant to the atmosphere. After the water is cooled in…
