Head stud help

Dieselroller · Nov 20, 2011

How can you tell if your head studs are bad? When the truck is cold, it has a rough start and wants to buck going down the road until it warms up, then its fine. Anyone know what it can be? No codes or anything else!

Sounds like injector stickage to me. Trow ya some Rev X in there.

Ya I second the injector stickage. What are you running for oil and how long are you running it. How many miles on the injectors also?

Spool valves hate cold weather. When was the last time they were out and serviced?

Dieselroller · Nov 20, 2011

Oil rotella t, and 2000 miles on it. Injectors 120000 miles, never cleaned turbo

Stiction i bet. Head studs have nothing to do with the way your engine runs,

Guess its time for rev x

Exactly what kind of answer are you looking for here, be specific just a bit more man.

STROKER · Nov 20, 2011

I'd give revx a try and see if that helps before you buy new injectors or get yours rebuilt, might be temporary but its a lot cheaper than pulling them

Dieselroller · Nov 20, 2011

Oh, spool valve and sticks. Never heard of it

cfdeng7 · Nov 21, 2011

Sticks = forum slang for injectors

Spool valves actuate the injectors and as they wear/age they tend to stick in colder weather.

Dieselroller · Nov 21, 2011

Oh, ok! Learn something new everyday! What is the spool valve and where is it?

Here's some reading for you

Ok thanks

This sounds just like my truck. I read the link about "stiction" and am now wondering, what is the FICM calibration referred nto in the link, how does a person do this, and what all does it do?

if you need new injectors. and you dont wanna buy aftermarket ones factory ford ones are 250 a piece pending on where you get them. try Sunrise ford. they are a vendor on here and they give 25% discount to forum members. its worth a try

no it's not....good lord man. there are lots of things to look at before throwing new injectors at it.

just try running a thinner weight oil and then some rev x. it's just stiction which is very common in these trucks. mine does it all the time. i'm fixing to put in valvoline extreme blue 5w to help with sticky spool valves. also, check your ficm voltage and see where that's at.
