N62 valve guide seal failure (poll)
 
I'd like to inquire:

How many miles on your N62 engine?

Have the valve guide seals bean replaced?

If yes, what was the mileage at time of replacement?


Very interested to know how many N62 engines have made it to old age without replacing the valve guide seals.

Thx!

2005

144k miles

No seal failure, no smoking

136k on my 04. No smoke with everyday driving, but will smoke some if idling 10 min or more. Im not worried about it until A. It gets to the point where it smokes on regular drives or B. I find a good indy in N.Jersey who has AGA tool and is priced accordingly, considering the time saved using the tool.

105K total miles. 2004 4.4 engine.
I bought it at 85K knowing I would need to do this.
Talked seller down 2500 dollars.

It would puff smoke if extended idle.
Engine did not burn any oil.


Indy did mine a few thousand ago.
No smoke, runs great.
Old seals were hard and not sealing.

109K miles no seal replacement.... smokes like a freight train if I park it more than 3 days.... burns 1 quart of oil every 200 miles if I travel at 90+mph.....got pulled over for a smoke show after it was parked for 2 weeks and gunned it going up an onramp about 3-5 minutes from my house... it passed inspection about 2 weeks before that so I told him I must have gotten some bad fuel... lol

Not old but.....Almost 99k miles now.....and no smoking issue.

Recommend to change engine oil/filter often and clean CCV/hoses with Compressed air.....or replace if necessary.

And don't forget............. drive it HARD every now and then!

98k miles.
Doubt anything has been done valve wise.
No smoke.
