Hello All,
I just bought a 91.5 5spd, with some mods. The guy i bought it from didnt seem to know much about the truck, but i got it at a great price! Now for the questions...
It has a leak on number 1 injector, right where the line goes in. what needs done to take care of this?
Driving it home today, i was playin with it a little, and noticed it will build around 30 PSI of boost, which i believe to be a little high for a H1C!
it will smoke on takeoff but definately clears up with a little air, and dont haze at idle, which is all fine with me. just wish i could find out a little more about its history, and what all has been done to the motor.
Thanks,
Wheelo

30psi is a little high (a little out of it's map range) for the h1c but it won't hurt it any and I wouldn't worry about it unless your EGTs are too high.

As for the leak on the #1 injector. I'd make sure the nut holding the injector line on is good and tight. Don't over tighten it though.

Aint 30psi a little hard on the head studs and head gasket? im assuming that the previous owner before the guy i bought it from upgraded them... hopefully.

nah they can take 35-40 typically. there are other variables too though. cylinder pressure is what youd like to know.

At only 30 psi it's fine. Sounds like stock injectors and lots of pump tweaks, or injectors and a stock pump.

I would not drive with a loose feed line it will erode the line or the stick or both just my $0.02

got in a little late tonight,(typical life of a power lineman ) didnt get to investigate much, but i did try to torque the line, and it was already tight. is it a flared fitting or like a compression type? The odd thing is, even with the leak, it dont miss.
Thanks,

It's got a flared end. Maybe pop it off and check to make sure it doesn't have a small piece of gunk stuck between the injector and the flare.
