Dear sirs,How do you check if your block is cracked?With heads off or on? Thanks for I have coolant in my oil,Let’s say that after removel of heads And the gaskets are fine then obviously I have a cracked block how do you determine that with the heads off or the heads on ? If the block is the culprit is there any tricks to know for sure?Thanks

I think you there is a tool similar to this that you can plug all the coolant channels and introduce pressurized air. Need to use a heat lamp in the process as well. Then spray soapy water.

95% chance if you have coolant in the oil you have a blown gasket on the front cover. It usually happens when the truck is overheated and the coolant pressure gets too high and blows the gasket out. Very common to have blown head gasket at the same time. You can tell if you have a cracked block by dropping the oil pan and pressurizing the cooling system and see where the leak came from. If it is running out from the timing chain area it is a blown front cover gasket. It is rare but the Intake gasket can blow and leak to coolant down into the lifter Valley. You can also see that with oil pan off. If you take the spark plugs out in the league is running out of the spark plug hole with the piston at the top of the cylinder, you have a blown head gasket. Most common on cylinder one, seven, two, or eight.

Thanks for the insite,It wasn’t over heated that bad.All though steam came out of under neath the hood.I let it cool til next day and it fired right up only to run a few minutes then died,I was going to do a block check on it but I still might that I have heads off.I have a straight edge and going to check for warping.I have a complete kit from Atlanta British and oem bolts this is my first time to under take this task but I can do it.I watched Atlanta British’s 2 part video on how to under take the task at hand,Iam sure glade I have you guys give me very important pointers.Thank you again figured out the o-rings and were they go,Oh one more thing does it matter how the fuel injectors wires go ?or should I mark them in order with tape 1,2,3 so they came from the same injectors? I know the spark plug wires should be marked.Yours truly

You can get rebuilt injectors on EBay very reasonably priced, and a good time for plugs and wires too while the upper intake is off.
I highly recommend molded Valve cover gaskets. The cheapies are a pain in the neck flopping around and the metal rings within the gaskets fall out very easily and can get into the Cylinder head.
I would also highly recommend changing your valve stem seals while the heads are out. I got burned on that and had to do the HG’s twice.
