Help me think this out.
Unfortunately it looks as though Ford is going to screw me over on the issue I've been going through based on the bull shit LL created. Now I have to fix the car and I'm going to let Paul do it but I'd like to get a feel for what I'm facing.
Symptoms: -Rough idle but smoothes throughout RPM band. -valve chattering -slight oil smoke from from exhaust -noticable power loss from low RPMs but less as RPMs/speed increases. Noticeable things: -no rod/piston knocking - leads me to think there isn't any "severe" internal damage -idle smooths - makes me think it's nothing more than a valve(s) opening/closing correctly --> also makes me think Exhaust valve. Follow me on this and see if it makes sense. Exhaust valve is not closing opening correctly thus not allowing the cylinder to make the normal power; creating a rough idle as the engine is then off-balance. As the rpms increase, the engine doesn't rely on each individual cylinder as much per se. The collective power of the entire engine is greater than each individual cylinder; i.e., inertia. Any thoughts? Am I flawed in my thinking? Another cause? |

Re: Help me think this out.
ok I am thinking that if it is a valve situation like you mentioned, that it is going to be rough at all rpms or at least noticable. Has anyone had the valve covers off and looked at the valvetrain?
Has the car been put on scanner to check for codes?

Valve chatter? When? What RPM? While idling? Quote:

Nathan: How can an offroad pipe cause oil to seep by either the valve guides or the rings?

If you got serious blowby (ie, busted valve stem seals or rings) then it sure won't be a "slight" oiling smoking issue.

Re: Help me think this out.
I dunno, Matt said it was blowing pretty good on the last dragon run. Guess holding 5500+ rpm in 2nd gear down the straights & through the whole 11mi run isnt good on the seals huh
