Got to work on the ST again today. The plan was (that's never a good start, LOL) to replace the #3 injector. While I was at it I was going to install the t-stat housing and do both tensioners. I used the link below as a guide, pretty decent step-by-step.
Everything was going well until I found the injector sleeve for #3 was broken, most likely that was the cause of the misfire.
I wasn't real happy to see that. Looked at rockauto they were between $11 and $18 but I needed them today, so I called a couple parts stores and NAPA had them but they would have them until Monday or I could drive to store. Since it was only 30 miles away I went and got them and found out they thought they were gold sleeves at $42. (sigh) Bit the bullet I wanted to finish the truck today. Got home had to watch a video to see how you install them.
Finished that, installed injector and fuel rail on pass. side. Started on t-stat housing, removed it and went to clean the surface for the gasket...
I don't remember seeing a set pin... Hey why are there only 2 bolt holes I did 3. (sigh) Well, at least there was a good 1/4" sticking out of the lower intake. Got some Vise grips and tapped on the set screws and twisted. 5 minutes later...
VICTORY!!!!
Had to run to the local Ace Hardware and find a M6x1.00x80 bolt.
Replaced the l/s tensioner and then installed the new t-stat housing.
Didn't think much about it at the time but the coolant sensors were kind of loose, didn't think about replacing the gaskets with the o-rings from the plugs. (sigh) Everything when back together really smooth after that and started to refill the coolant. 1/2 way through the 2nd gallon I start hearing water dripping. Look underneath and sure enough (sigh) coolant dripping from front of engine. Grab a flashlight and searched to see if I missed a hose. Nope both coolant sensors were seeping. (explicitives followed)
So, I tried to just loosen intake and get to the sensors but no joy. So, I have to repull the intake on the 4th.
I swear this truck likes to fight me. LOL but I will succeed.
I do have a question though.
I think the PVC valve is bad because 1 and 4 intake runners were oily and gooey on the inside. A sticky gooey. Would the PVC cause this?
