Need a little direction on my build. After putting it together I found that I had water dripping into #1
and 3 some how? This was before break in on my test stand. So I either did something wrong or maybe I have a crack. Anyone ever have this issue? Any thoughts would be great before I start taking it back apart.
Not knowing what you did with the engine, did you have the heads resurfaced to ensure they were not warped? Did you have the block checked to make sure it was not warped? Were the surfaces perfectly clean of all gasket material & age old residue?
Were the heads/block magnafluxed for cracks?
Did you match the head gasket up with both the block and cylinder head to make sure all your water holes lined up? Did the head gasket have a front/back or top/bottom positioning - as some do?
Are the alignment pins in the block installed correctly?
Were the heads ported and someone broke though a water jacket?
Did you run a thread chaser down the bolt holes in the block? Did you look in the holes to make sure no debris has fallen into the hole not allowing the head bolt to tighten? Did you put way too much oil on the bolt threads and it has dripped into the bolt hole causing hydraulic pressure not to allow the bolt to seat all the way down into the hole? - also good way to bust a block when the oil gets hot and expands.
Did you mill the head and NOT compensate on your head bolt length and now they are too long and bottoming out rather than tightening? If so, you may have busted the block. Did you use aftermarket bolts? If so, did you get the correct ones? RA IV bolts have a few longer than stock bolts and will not tighten up (ask me how I know). There are different length bolts used in the Pontiac head, did you install them in the correct holes? Did you torque the bolts in sequence and use three different torque values to evenly seat the heads?
Let's start with all that.
