Current Status: DONE! (Day 11)



I have to replace my 16 year old Jeep Grand Cherokee 5.2L V8 engine. It no longer passes emission testing and smokes like a mosquito fogger!

Being this engine swap-out project will take several days I’m going to post each day’s progress below with a DAY Number heading marking each day’s work. Unfortunately this will not be a full tutorial but rather just some eye-candy photos and progress blurbs. You will learn what is “generally” involved in replacing a motor and you may realize it is something you could do someday instead of junking out a nice vehicle and taking on 5 to 6 years of new car payments.

In the past I normally pull my motors, tear them down and replace and rebuild as need be. But that takes a ton of time so for my Jeep I decided to order a fully remanufactured “long block” from Engine House in Phoenix, AZ. They have a great rating with the BBB and everyone I asked recommended them.

Below is a photo of a remanufactured “short block” which does not have cylinder heads installed. With a short block you would have to use your old heads or get new cylinder heads and install them yourself.

I chose to use a new “long block” like seen below which has new cylinder heads already installed. 

If you need new cylinder heads its cheaper to just buy a long block, plus its a big time saver not having to put the cylinder heads on yourself.
