Rebuild and investigate
 coolant in oil and no oil pressure

Right now the engine is set up for NA naturally aspirated.  I'll be refurbishing it and investigating for reasons that coolant is in the oil and no oil pressure and also setting up for forced induction.

Clean up the major dirt prior to removing the intake manifold.

Very clean inside.

Oil pump drive gear is so worn that there are no gears left.

Crower roller rockers.  I've never seen a set of Crower stud mount rockers.  Nice!

These guide plates located the roller rocker tip dead center on the valve tip.  Pushrods are 7.150"

All looks great.

See how the head gasket blocks off oil drain back at the left (driver's) head.

#1, #3, #5, #7 look pretty normal.

#8 looks like coolant from either head gasket or cylinder crack.  I cannot see a crack although there may be one.

Lifters all pulled out of their bores nicely except #4 exhaust but it feels and looks like all the others.  I don't know the brand of lifter but they all have #538 lazered onto the side of the roller. Oh, and one of the 16 lifters is an odd brand.

Water in the oil crusted up the oil pump pickup.  I still need to remove the pump and spin the pump to see if it seized up and caused the oil pump drive to sheer it's gear.

Yucky crust in the oil pan.

Nice double roller timing set.

Crank sprocket at the zero position.

I like the plugs that were drilled for a tiny oil weep hole.  Kudos and good job to the original machine shop and or builder.

Cam is a billet core.  It's in good shape.

Cam bearings are ok too.
To do:  Remove rotating assembly,
Block to machine shop,
Check for cracks in block,
Hone or bore the cylinders,
New pistons (for forced induction).
New balance,
Refurbish cylinder heads

I am easily impressed.  The shop that did the balance of the crankshaft has a neat and clean method to record the balance bob-weight.

This is piston #8.  For now I think there was a slight head gasket leak.  Little leaks make big messes.  Head and block testing will verify all is good with the heads and block.

Rod bearings are typical for having coolant contamination and some dirt.  But also there is more bearing pounding than usual.  The top bearings on the LEFT bank (1,3,5,7) are worn at the top as if there was some or occasional detonation.

Stock main caps are not the most stiff but this is the most crank-walk I have ever seen. Crank-walk is pitting or cavitation or micro welding.  

So I'll be talking to my machinist friends for advice on this.  Was this caused by tune up? By tune up I mean detonation or just too much power for the caps to hold the crank firmly.

Main bearings Ok with the typical dirt/coolant contamination.

Different views of cylinder #8.  I don't see a crack.
