smokes in the morning

[grant]

WHEN MY WAGONEER SITS OVER NITE AND I GO TO START IT. IT SMOKES FROM THE EXHAUST PIPE FOR ABOUT 3 MINUTES.. IHAVE 190.000 MILES ON THE ENGINE. AFTER THE 3 MINUTE SMOKING PERIOD IS UP THE SMOKING STOPS.IS THIS GOING TO BE COSTLY TO FIX... THANKS

Prolly just the valve stem seals. Personally with 190k on the clock I'd leave it for now and wait till you rebuild the motor.
If you do get new seals I wouldn't get the heads totally redone in case you're thinking about it. Fresh heads with all that new compression on a 190k motor will likely blow the oil rings out and then you'll really be smoking...all the time.

Hi Grant! Welcome to the world of FSJ's and this great place to hang out and talk JEEPS (My personal favorite Subject) :D :D
As -joe mentioned valve guides and seals will cause this, you may also notice a puff of smoke when you let off the gas quickly and coasting down the hill. Where in MI are ya

THANKS JEEPMAN FOR YOUR WELCOME TO THE CLUB... I HAIL FROM DETROIT, WHATS THE GOIG PRICE TO REDO THE HEADS...

Grant,
You can change the valve seals without removing the heads. Just need a spring compressor, and an air supply. You bring the cyl. you are working on up to TDC, then pressurize the cyl. using an adaptor that threads into the sparkplug hole. Compress the spring, and remove the keeper. Take the spring off, and replace the valve seal. Goes back the same way. Tools, seals and gaskets might cost as much as $50.00. Not a hard job.

Yes the valve stem seals can be changed with out removeing the heads as mentioned. However, I would run a compression test, monitor oil pressure, decide whether the work is worth it or not. At 190,000 miles I would question putting anything into it. Unless it was serviced regularly, and is in above average condition. I would certainly not redo the heads as in complete head job and put them back on an engine with that many miles on it. Sometimes leaving things as they are is a good thing. ;)

I say a can of "motor honey" for a engine with that many miles. Wait for an overhaul. In school I have a friend who's car burned oil so bad he only put in used oil from other oil changes. Never changed the oil(junker car). He drove it that way for 6 to 8 years that way.(it didn't take that long to get through high school for those who might be wondering ) ;)

THANK U VERY MUCH GUYS... VERY INFORMATIVE

Actually, you can do the job without an air supply. Just use some stiff nylon cord and stuff a good bit of that into the spark plug hole. Then SLOWLY turn the engine over by hand until the cord seats up against the valves--of course, by this time you've already removed the rockers. Anyways...the cord holds the valves in while you change the springs or valve stem seals. Works like a charm and ya don't need a fitting or compressor. smile.gif

I will jump on the "don't bother" team. Two reasons, one, if it only smokes for 3 minutes, then that is a lot of effort to fix a relatively minor issue on a high mileage motor. Second, as others mentioned, if you do have the heads redone, the higher compression will find the next weak link!

True story, my first FSJ was a '78 w/401 TH400/QT w/low range. Since I was moving from KS to CA I decided to sell the truck (sniff sniff). It had one dead cylinder due to burnt valve. The new buyer had a complete valve job done, rebuilt the carb, and had it running like a top. He drove it from KS headed for KY and threw a rod at the MS river! (I didn't feel so bad about selling it then!)

And yes, I DID tell the buyer about the dead cylinder, as well as a professional mechanic's opinion of the dead valve, and the possibility of problems resulting from higher compression.

I can't help but ask. What color is the smoke? And does it run rough? Could be a choke thing if it's black and you smell gas from the tail pipe.

[grant]

I NEVER REALLY PAID ATTENTION TO THE COLOR OF THE SMOKE BUT I WILL CHECK IT OUT AND REPLY BACK. I RUNS ROUGH WHEN I FIRST START IT ESPECIALLY DURING IDLE. FROM THE SMELL IT SEEMS TO BE RUNNING RICH.
