My 04 SOHC 4.0l engine has about 200k on it, and I blew the head gasket. When I opened it up I had broken front and rear timing chain guides. I am replacing the timing guides and head gaskets, and I have the heads in the shop right now. I'm trying to get the new crankshaft bolt in the mail because my dealer doesn't stock anything older than 2010. My Haynes repair manual only emphasizes replacing the crankshaft bolt, and the head bolts, but everywhere I look online and on Youtube people are replacing the jackshaft bolts and camshaft sprocket bolts as well. Exactly which bolts need to be replaced, and where can I buy good ones online for the best price? I do not see them on Rockauto. I bought the Cloyes 90398SB timing set, and the Engintech F244k5 upper and lower gasket set, with the Enginetech head bolts.

 

My dealer wanted $300 for 5 sprocket and pulley bolts. They apparently changed the part numbers since 04 so I was having a hard time finding the bolts online myself but I paid $200 for 5 TTY timing bolts on freedomracing.com. I’m sure there’s a better way, but it’s the best I could find. I can’t believe the cam sprocket bolts are $60 a piece. For me, sourcing these damn bolts has been the most challenging part of the rebuild.
