Any red-flags?
« on: June 15, 2009, 07:46:58 AM »

Here are some pics of my engine's cam and pushrods.  I have no idea what I'm looking at in terms of trouble-shooting so I was wondering if you guys notice anything that would raise any "red flags?"

Like, for instance, there seems to be rust on the sprocket that turns the distributor shaft.  And is it normal for the cam lifters to be streaked in brown, like that?  The engine has about 95K mi on it.

Image order is from engine front, to center, to rear.

If the tops of the lobes are deeply pitted and appear worn, then the cam is done.  I don't see any signs of abnormal wear

Looks like normal wear for a high mileage engine. You may have also had a plugged up EGR system aiding in the sludge development--that's why it looks like it was coated by a can of spray undercoating. Plain old dirty unchanged oil will leave a coating that has the consistency of margarine.
