Great write up. I'm curious, how did you narrow the culprit down to the valve stem seals vs other possible causes for oil getting in cylinders?

Two suggestions. Put some lube on new seals before installing them. I use new motor oil. Also it's better to loosen valve adjust lock nut and back off the adjuster before removing rocker assembly. Saving the time it takes to adjust valves is not worth it. Not loosening them makes it harder to install rocker assembly and easier to damage something. Valve lash will/can change removing and reinstalling rocker assembly. Ask me how I know this.

it took me about 3 weeks to narrow it down to valve stems seals. The problem started with me leaving my car idling while I ran in my work to grab a couple things and I came out and it just blew clouds of what looked like white smoke. So initially I thought it was headgasket or my intake manifold leaking coolant. Leakdown test proved it wasn't headgasket and I retorqued all my intake manifold bolts so I knew it was not that. Car didn't smoke again so I figured the problem was gone but then I noticed while filling up I had burned a lot of oil in a short mileage.(quarter of a quart in 250 miles as to where i used to only burn a quart every 3000 miles) So I had recently had my injectors cleaned and it had thrown my tune off(I have kpro) So my car was running really rich. Then I was worried my oil rings had been washed out but my compression rings were still fine.(good compression numbers and leakdown numbers). After all of that I stuck a bore scope down my spark plug hole to take a peak of the cylinder walls were scared. Cylinder walls were perfectly fine but after sitting for two days I could see some oil on the #4 piston on the exhaust side. This is when I was fairly positive it had to be the valve stem seals. If my oil burning issue decides to have stuck around after putting some miles even tho so far it seems fixed the only remaining thing it can really be is the oil rings. Hope this fully answers your question of my stressful journey to finding this problem!

Any news to report on the new valve guide seals reducing your oil consumption?
Thanks for your write up

Mullallyman -- where you at? How's your oil consumption? Any updates?
