Bought myself a Primera P10 today. Knew the engine was in a bad state, but wasn't prepared for what i saw, when i pulled the valve cover..

Car was run a couple of months without engine coolant. Still ran today, just barely though..
Yep, thats a rocker arm laying around in the head. 7 rocker arms are molten, with debree spread around inside the valve cover and head. 3 shims are also missing :26:

You know what... I've been driving this minivan for a bit just for small commutes, and the water pump is out out. Like... no water for 2 months now out. I wonder what the inside looks like on it.

Thats not from overheating. Looks like no one ever changed the oil and all the sludge plugged up the oil holes for the valve train. I have seen so many SRs die this way.

I disagree, that's from an engine that got too hot and began to cook the oil. Then as it cooks it builds up and as you said will clog the oil ports. But even dirty oil doesn't cause this until it gets really hot. You can tell by the way its baked on the walls of the head that it was really hot in there.

Considering the engine beeing driven without coolant for the better part of this summe, I'm pretty sure it was damn hot in there. Actually, in the end the engine was so weak that the owner had to floor it in second to get up even small hills. Since norway prettymuch is made of hills, the poor SR was doomed..

Anyways, here are some more for you :p

This was the worst rocker arm, though most of the stuff on it is sludge

I have to disagree with you. The engine would have stopped running long before it got hot enough to "cook' the oil. Its just sludge. that what happens when the oil never gets changed. Its not baked on the head its just oil stains, all engines that aren't new have oil stains in the heads.
