Well first, hello to everyone! I just joined today. I've been reading an researching for a while now on posts from you guys and have yet to have any luck. So I figured it was time to join up and get some opinions. I bought a 2000 f-350 a few months ago. It smoked a fair amount. That's why i bought it. I wanted a new project truck. Which has turned into a nightmare. When I bought it, I smoked a good amount at start up and would smoke less after it warmed up. And eventually go away. Had very little blow-by. Passed the oil filler cap test. Since I bought it, I have basically done everything but take the motor down to the very bare block. It smoke like a freight train. When you start it, when you drive it, when its sitting at idle, under a load, all day, everyday. I put a brand new set of injectors, motor craft beru plugs, new VC gaskets with UVC harness, a complete new wiring harness for everything under the hood because the old one was a mangled mess and had way too much electrical tape and zip ties for my liking. Plus I couldn't even get my scantool to connect to the truck cause the computer stuff was shot. New fuel filter. New ICP and plug. New turbo and pedestal (orings between pedestal and turbo leaked, turbo seals were shot, and EBPV was leaking). Also cleaned out the inter cooler that was full of oil before running it again after turbo change. I was using my SnapOn scanner but I stepped up my game yesterday and bough an AE with the enhanced ford setup. Anyway. The only thing I have not done, is a compression test. Which is basically the very first thing I should have tried. I know, I know. I'm not the brightest. Anyways, the truck smokes more than my 90 year old grandma that lives alone with her 83 cats. And for the life of me, I cannot figure it out. I guess you could say I'm avoiding the comp. test because I'm afraid it has a dead cylinder. And I don't want that to be the case. Any ideas?

I think it's time to embrace the suck and check compression.

 

Bad valve seats won't show blowby. Suck it in until your chest puffs up - and while you're looking all manly, check the compression. Nothing excites the girls like a chest-puffed manly man checking compression on a diesel.

 

Well I guess it's time to nut up and do it. I'm just afraid the numbers are going to show what I fear. I've been through 5 different 7.3's. And this will make the first one with a bad cylinder.
