yeah it definitely has a lot of blow by coming back thru the intake, you can see it plain as day when you rev the engine up. when i first heard the symptoms, i wasnt there when it all happened, i was like shoot that motors done, time for a new one, been trying to find a 4bt cummins no luck tho, plus it would be more work than i would want right now.

 

a 4bt would be a really sweet fix. Waiting to put the 6cyl cousin of the 4bt into my 96 Ford. Some day it will happen. Some day

 

yeah im familiar with a 4bt, but they are expensive and hard to find in this area, but it would be a permanent fix for as much as she drives this vehicle haha. It would last longer than the truck itself. I think ill just call the donor vehicle owner, kinda scary no mileage listed in add, so it might be another high mileage motor
