I'm New Here
This is my first post. I bought an RV-4 in June. Love the airplane!![Big grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
It turns out the crankshaft is cracked due to the Nelson Balancing AD.
When it was reground by Nelson Balancing, they gound the wrong radius into the journals and many of the crankshafts cracked. Mine was one of them that cracked. Now I find all for cylinders are cracked as well.
At this point, I am just planning on buying an superior XP-360 or Titan OX 360, assembling it, and using all of my old accessories (the engine only had 250 SMOH. This is what sitting with no use does).
A couple of questions.
# 1 Is the Superior engine the same dimensionally? IE will all my old baffling, exhaust pipes, etc. just bolt on? or will I have to re do these things? I noticed that the Titan engine has tapered barrell fins.
#2 My old engine was an O-360 180 hp. Can the superior be set up to have 180 HP and still run on Auto gas? I have noticed a few different compression ratios.
#3 Any other issues I will have in this installation?
#4 There seem to be a lot of options when purchasing these engines. Roller rockers etc. Which ones are worth spending the extra # on?
BTW : When I get the new engine, I will have a lot of parts for sale. Engine Cases, rear accessory case,yellow tagged camshaft, pistons, valves. Pretty much everything minus the crankshaft, cylinder studs, and accessories.
I will put these items up for sale to fellow RVers.
Thanks for your help.
