    T-stats keep sticking open or closed

    I have replaced the T-stat in my 5.7 3 times in the last 2 months. I have the kind of T-Stat that uses the rubber ring to secure it to the top of the T-Stat housing. The first time I noticed that the engine was running cool. It would only get up to about 120F unless I really ran it 3/4...

    Well per my earlier thread I was changing the bellows and gimball bearing when I found an exhaust shutter/flapper in the exhaust. I saw mentioned a few times on here recently that some shutters were eliminated from the current Y-pipes, and Volvo doesn't use them anymore. So... Do I really need...

    Riser/Manifold leak?

    This is a new engine (in July) that came complete with these manifolds and risers. I noticed a little tiny rust spot about a month ago and it has gotten worse and now as you can see the rust is all the way around where the riser meets the manifold, and you can see where water actually dripped...

    First engine rebuild

    Re: First engine rebuild I went to the machene shop today with all of the pistons. The older guy whom I talked to originally was there. He told me that there was no point in checking all of the pistons. He said I need new ones if 2 are that far off. He also showed me where the rod had been...

    Re: First engine rebuild Ok heres pics of each side of the 2 pistons in question right now. These are the #2 and #8 pistons. The guy at the shop showed me where you can see the piston was rubbing. I think he means rubbing on the piston wall from before. There are tiny grooves or marks that...

    Cobra trim ram(s)

    When I went to my boat yesterday I noticed that there was oily fluid leaking from the drive somewhere. I found out it was from the port side trim ram. I noticed that where the ram enters the cylinder there was a ring shaped piece (seal maybe) that had come off. I slid it back on as tight as I...
