I posted this in the engines forum also.

I have to pull the upper/lower manifolds off to fix a coolant leak. I have 5 of the 6 bolts out but can't see what the bolt in the center needs. This one is accessed through a gap in the aluminum "runners". Is it a hex or what? Anyone know.....

While I'm at it I might as well change out the injectors as this '90 5.8 has 240,000 miles on it!!! Do I just go with stock or aftermarket injectors? How much for a set?

Thanks,

Lance

 

You will need a torx t40 bit for the center bolt. You can get a set of injectors for around 200 bucks.
