hey is it possible for the valley gasket to make the oil in my engine milky? as i trying 2 figure out if its a head gasket or valley gasket as i took it apart and the valley gasket did have a few splits and holes in it but my oil on dipstick looked like chocolate milk and under rocker covers there's a build up of sludge under them, i just dunno if its the head or valley.
thanks aaron

Thing is mate, they can both cause coolant in the oil. If the valley gasket is in the state its in then it's a sure bet it's the problem. But........

If the Lower Intake Manifold (LIM) gaskets fail its usually pretty obvious where the gasket has eroded.

If the oil has gone milky but the engine runs and idles fine I'd go with LIM gaskets not head gaskets.

Head gasket failure will normally result in water/steam coming out of the exhaust, I'm not 100% sure but I don't think LIM gasket failure does this.

Leaking/blown inlet manifold gaskets can cause coolant to be expelled from the exhaust, have come across this a few times now with these engines.. The coolant leaks where the gasket sits around coolant port between the inlet manifold and cylinder head, and it leaks into or gets sucked into the inlet runners, then into the cylinder(s) and out the exhaust. If the gasket starts to leak badly, it can cause a hydraulic lock in the cylinder which can bend conrods etc.

grab the right size spanner and see if the inlet manifold bolts are loose . They tend to come undone over time then it leaks .
