I had no idea the forum had this feature until I stumbled upon it today and I was surprised at the quanity and quality of the comments found there. I'd like to publicly thank those who took the time to make them. You know who you are.

Fix fix the mixture problem then inspect for carbon deposits on the pistons and valves. You may not have enought to matter. If you do the best way to clean them is with water injection.

Lol, yeah good stuff. The socket trick is indeed an oldie but goodie. A ball of paper wadded up in the socket keeps the keepers under control too but whatever works.

Lol, this place never ceases to amaze me. I really wanted to see him use that duplex receptacle ;). Btw Ian, valve retainers are called "keepers" over here.

All that is about as valid as believing boost gets you laid. Seems you know as much about oil as you do about women ;)

No....it won't.

A higher cap won't neccessarily raise system pressure. And even if it did why would you think increasing system pressure would make the engine run cooler? All it'll do is raise the boiling point of the coolant.

Wax is an additive?? You'd better check on that ;) The sludging caused by Pennzoil is a problem of the long ago past and it's a good oil these days. In fact, the chemistry of the new Platinum is looking to be a great step forward.

Amen. I can't tell you how many posts I ignore based on this alone. Writing is crafting. It's no different than crafting anything using your brain and hands. Take some some pride in it. Anyone can come across as an idiot you know, it takes no skill at all.

Thats not true with Group IV or V syns. As Geezer says, there is so much myth and misinformation about oil the only way to get the real facts is to study the science behind it in depth. A good place to start is here: http://tinyurl.com/b7kr6

Rotella T 5-40 or Delvac 1 in the summer, German Castrol in the winter.

oneandgone: What's the story on that clear timing cover? Interesting. Where'd you come by that?

Works good. Smells good too. Just be sure to rinse it off well as it's corrosive to aluminum (read the bottle). The military stopped using it for that reason. No longer permitted around aircraft for example.

Say what? You can't test a narrow band O2 sensor using an ohmeter. In fact you can damage it that way. It's always better to test it in the car but the best way to test it off the car is using a voltmeter and a propane torch.

Lol, just yankin yer chain mate. At least you know the difference between a quart and a liter ;)

It does. What part of "the ECU shuts off the injectors during decell" didn't you understand? ;)

By "backfire" I'm assuming you mean muffler explosion. The term backfire refers to combustion in the intact track. ME is always caused by fuel being combusted in the exhaust system. You have a rich mixture, a misadjusted dashpot, an overheated cat due to the rich mixture coupled with exhaust...

Nick: Thanks for your input. No leaks downstream that I can see but that's one reason I need to sample engine out rather than tailpipe. CO is just a bit low (.3%) but I'd expect that with a lean mix. HC is slightly elevated so I'm inclined to think it's a misfire in one cylinder. I have two...

Lol, now hold on....10 quarts and 10 liters aren't the same thing are they?

No kidding. IJ can you confirm?
