Thread: Newly rebuilt fe390 still smoking after intake redo. Leak Down Test? Wrong pcv valve

Tweet

All I've heard you complain about is a little smoke from one side, and you've confirmed with the leak down test that your rings aren't seated fully. Sure, you can tear it down and start over, but if it were in my garage I'd be taking it out and driving the P!SS out of it for the summer, and if it's still smoking in September buy a new engine from one of the reputable FE specialists out there and start again when it warms up. Oh, forgot you're in Tallahassee - drive it until it quits smoking, or you get sick of it and then buy the new, fully assembled and tested engine.
Sorry, but the answer just seems so logical to me. I'm done, and won't post here again.

Thanks everyone for your replies. No I won't be breaking it down any time soon. I took it out today for a good run and had a lot of fun as I always do when driving it. I'm going to put a few hundred more miles on it and then take some more readings just to see if they're any changes for the better. THe main thing here that I was concerned about is that this engine wasn't smoking in the beginning when it was just starting out getting broke in. This developed after the first couple hundred miles. Maybe this is normal. This is my first rebuild and I have learned a lot from everyone. Thanks for the knowledge you have shared with me. Good Karma coming your way. Thanks for putting up with my ignorance. I hope others will benefit from this.

Thanks Denny. I'll keep my fingers crossed and keep driving.
