sorry i didnt add enough info. i have 1994 GMC 1 ton with a 6.5 turbo. i have changed filters, remounted the PMD, now i found the leak under the filter housing located on the back of the motor on top. there is 3 hoses that run to it. i have tighten every thing i can get to. i changed the injector pump 6 years ago. so its started this in the last year.
truck is my work horse. going after wood on weekends.
let me know what all i have to do to remove the filter housing to find the leak. do i have to remove the intake manifold? is there a remote filter i can use in place of the orginal?
