Finally getting to work on my Wilmar Wrangler loader. I'm running into a bit on a issue with the engine. If you go by the number stamped on the block (HA00395N40746H) it comes up as a 4.165. But on the head it has cast into it 4.154. From what I've found these two engines are in the same family and thinking the 165 just has a longer stroke. When I try to search for parts or other info I come up with next to nothing when I search the 4.165 but when I search the 4.154 I come up with everything. Need a water pump, thermostat (didn't have one in it) and upper gasket set. Taking the head to a place tomorrow to get checked over and hoping there is no cracks and if there is that it can be repaired. So far I noticed a crack between the valves on the back two cyl. which from what I've seen tends to be a common spot on any engine. Also it looks like the pre-combustion cubs stamped the head gasket? Engine ran fine but it would fill the coolant with bubbles, I did a band aid fix when I first got it (6 years ago roughly). I've come to rely on the machine way to much so its time to fix it proper.
