JobU - The top photo is a 2.4L, but the pics you sent me yesterday are 2.5L powerhead. The pics you sent me with the Oil injection check valve and thermal air valve ( hoses goes to carbs from starboard side head) . . . There are no missing hoses in those pics (well somtimes there is a small 6" section of hose on the 2psi check valve that goes to no where). Hope this helps.
