Another thing that I think is odd is that when the engine is cold there is very little oil mist going out the valve cover, but when it warms there is more.

My friend has the exact same problem with his AAZ. We believe we traced it to worn rings in cyl #1 but have not taken the engine apart to confirm this. We did a wet and dry compression test.

I'm trying to find an inexpensive compression tester to get more insight into this problem.

ebay has some cheap ones that work well.

I just bought one off ebay that I can test through the glow plug threads. I should have it by next week

what grade of oil are you burning?
15w40? or thinner?

I finally got around to pulling the head today. I plan on replacing it with another, but I noticed there was a lot of play in one of the exhaust valves. even with the pressure of the cam on it it moves about 1/4 inch side to side. I think the valve guide is gone. Would that cause this much oil consumption?

yes, and your lucky it hasn't run away. haven't you said that the valveguides were replaced?

TPW · « **Reply #24 on:** July 06, 2008, 03:53:15 pm »

Yes they were just replaced less than 3000 miles ago. What caused them to go out so fast?

gigaz2 · « **Reply #25 on:** July 06, 2008, 04:54:29 pm »

someone put a wrong diameter guide? only a possibility, but either way, the machine shop should be responsible for that.

or an inferior valve guide... magnesium would last a long time

Who sell magnesium guides?

magnesium?

Are you thinking Managese Bronze (CDA 863)? Known as Mag Bronze, Its good for heavy loads at low speed.

The stock Bronze valve guides are actually top notch, it used to be an upgrade for the US built engines to go to bronze valve guides from their POS iron guides.

I don't know what the stock guide alloy is. Befor we condem the stock guides right straight to heck, maybe we should find out what the alloy is. It could very well be mag bronze all ready.

My job involves working with (and knowing, to a certain extent) allot of different alloys.

this ones lasted 3000miles... I doubt they are stock, or someone put the wrong ones in.
