I am pretty sure theres only 26,000 miles. I looked that engine up and down for hours when I first got it and everything lookd original. I called the dealership (whiteside Chevrolet in St. Clairsville ohio) and asked what all was done to it when my mother owned it. They told me that they replace some coolent nipple (metal one to replace a plastic one that broke) they replaced the entire cruise control system, the engine and the engine'* Computer. I asked them how many miles where on it and he says he wasn't sure but they do look for an engine with the lowest miles to put in cars. Plus my stepdad saw the car it came out of and it has like 22,000 miles on it. I used to work for this dealership and there pretty good people. Heres how good they are. This car was sold to my mom AS IS. No warranty. When things started breaking the salesman who sold the car to my mom saw to it that everything was to be fixed at the dealers expense. When the engine went my mom was ready to junk the car cause she didn't have money for a new engine. She called the dealership, who towed the car when it died, and they said they would take care of it. They called my stepdad to look at this engine with them when they located it. He saw the low miles so he said ok. When it came down to the money they sold the car to my mom for , sold as is, and the money they spent to fix it they probalby lost a couple grand.

Sounds like the coolant nipple to the upper plastic intake. The L27'* have had problems with that.

Have you considered trying a can of RESTORE to seal your valve guides? I've had good luck with that product before.

Much of your problem may be the low miles. My car sat for 5 years in storage before I bought it, and it had a few problems as a result. Those seals get dry fairly quickly for lack of use.

Yeah being the car it came from only had 22,000 miles when the dealer pulled the engine and the fact that its a 1994 it must have been sitting for a long long time. It only smokes when you first start it. The last time it did this was I think two weeks ago. Being that it very seldom does this it must not me too bad. Do they get worse if it is the valve guides?

You need to recondition/seal those valve guides. The sooner the better. I really think you can recover it. That restore is good stuff for some things. It'* the only 'mechanic in a can' I'd reccommend.

It'* great for sealing score marks on the cylinder walls of high-mileage cars, but I think it would really do well for your problem also.

It WON'T do you any good if your valve seats are hosed, but that'* not your problem anyway.

Buy a can of the 6-cylinder formula, and follow the directions on the can. It won't hurt anything, and may solve your problem.

Will this Restore stuff work with full synthetic oil? I was thinking of going with Mobile 1 Full synthetic next oil change instead of my usual Valvoline Durablend.

I'd add it now. And run it for the reccommended interval. See how it does before you switch to synthetic. It'* designed to work with dinosaur juice, I think, but it should say on the can. You might even run it for 2 consecutive changes to be sure. Then switch over to synthetic.

I know Valvoline is known for re-conditioning seals, but it takes time.

Thanks guys, glad to be here. Hopefully I'll figure out this profile thing and can share my experiences. Cresting a total count of 60 cars since I started driving in 1976, and still own my first one- a 67 SS Chevelle big block 4 speed, so I know the gratification of taking care of my iron. Back to the problem, I have seen cars after sitting awhile start drying out the gaskets, both externally and internally, which could have led to the problem. So dont discount the condition of an engine because of the mileage, if you store a vehicle for any length of time, it is good practice to start is occasionally, put it in gear to circulate tranny fluid and fire up the air conditioner, alot of the internal seals are self lubricating, and will need a little lubrication to prevent a drying/hardening process. Unfortunately, salvage yards arent in the business to retain items that are still in good shape, they just want to turn them over FAST....so the fresher the iron, the least likely to have problems. It'* still a decent fix if you hafta replace the seals (complexity scale of 1-10 probably a 4) Good Luck!

If it gets worse I will look into getting seals replaced. But since it only smokes once in a blue moon its probably a very small leak. I will try that restore and see if it goes away completely.
