I am intermediate level mechanic trying to do an advanced project, the cost of having it done professionally is more than the vehicle is worth so, what do I have to lose?
The mileage on the vehicle is about 85K and it has the 4.0L V6 Flex-fuel, automatic transmission, 2-wheel drive.
While under moderate acceleration and a speed of about 40 mph I heard (and felt) a very strong thud/bang from under the engine and then continuous thunk-thunk-thunk until I was able to pull the vehicle over to the side of the road. I had it towed home. When I tried to remove the oil dipstick it got lodged after about 4" were removed and won't move in either direction now.
I am in the process of disassembling the engine to remove it and then either attempt to repair/rebuild/replace it.
When I dropped the oil pan there was a lot of shrapnel in the pan and a 2" section of a sheared off T-bolt with KX1-920 engraved in the top of it.
When I looked at the upper oil pan there was a 2" diameter hole behind the starter and multiple holes in the upper oil pan, probably the source of the shrapnel.
I just removed the upper intake manifold and stuffed into cavity was an object that looked like a 4 inch thick jigsaw puzzle piece that essentially is a plastic bag with a sponge inside.
When I removed it from the cavity there is a pool of clearish liquid on the bottom with a lot of greenish white crystalline material around the sides of the cavity.
All of the tubes in the intake manifold are heavily carbonized with the exception of #6 (I believe, back driver side) which actually appear to be pretty clean.
I have photos of all of the items that I described but I have not figured out yet how to add photos to my post, this is my first one.
AT this point, I am asking for any guidance on what happened to this engine and what are the chances of repair/rebuild/replace?
Thanks.
