I finally got it all done this weekend. Here is the list;
1) New EGR Valve
2) New PCV Valve
3) New MAP Sensor
4) Billet Tech. Catch Can
5) 16 New Champion 570 Plugs
6) New Air Filter
7) Oil Change (Mobile 1 Synth + Mopar Filter)
8) Serpentine Belts
9) All New Wipers (for good measure)
10) Fomoto Oil Valve
All installed fairly easily. I an not very mechanically inclined. I don't even own a real set of tools. I went to Harbor Freight and bough myself some cheap-o tools to hold me over, plus I bough this spark plug wrench which made my life much easier.
Amazon.com: GearWrench Tools 41740 3-Piece 5/8-Inch Magnetic Universal Spark Plug Service Kit: Home Improvement
I purchased (and used most of ) 3/8" Metric sockets, 3/8" drive deep metric sockets, universal joint set, wobble extension set, 3/8" drive click type torque wrench. Along with funnel, oil drain pan and oil filter cup type wrench.
I didn't take to many pictures because I simply wasn't 100% confident in everything I was doing, I didn't want to spread mis-information by doing a write-up. How ever I will tell you where I ran into some minor issues. I present to you the novice mechanics guide to all the work I just did.
Installed PCV, easy.
Removed air box assembly, easy.
Cleaned throttle body, tedious but easy. Took about 1 hour. Used a few microfiber rags and 1/2 bottle of 91% iso. alcohol. Also used a new crest vibrating/rotating soft bristle tooth brush to get into some tight, more gunked up spots. Worked awesome, just kept dipping the bristles in a cup of alcohol. I'm picky about cleaning. I got every nook & cranny with q-tips. It's shiny and spotless. FYI for anyone who doesn't know much about motors, throttle bodies don't ever fully close, it closes like 98% with a small gap. I thought mine was broke, had to call mechanic friend who backed me off the cliff and told me all was well. Again, this is the novice mechanics guide.
First issue I ran into was removing the studded bolt that holds in the radiator overflow/reserve tank. This was probably just because I didn't have the right tools, my deep well socket couldn't fit and I only had a small box wrench. Tight space made it take longer than I wanted too. But not really a big deal.
Next was removing the old serpentine belt. I was alone and didn't realize how tricky it would be, at least for me, to crank down on the tensioner to loosen it with one hand and try to remove the belt off one of the pulleys with the other hand. I had a fear of slipping off the tensioner and getting my finger trapped between the belt and a pulley. I took my time and was careful, still have all my fingers. A helping hand here would help. If that helping hand could crank the tensioner from under the truck it would make it even easier I suspect. I had the same issues getting the belt back on, just reversed, lol. Don't forget to check all your pulley and bearings. I forgot to and my annoying pulley squeak is still there. Gonna have to get in there again son.
Removed the EGR Breather, easy.
Removed the Alternator (i went this route for the EGR install, I figured the 2 bolts holding the alternator was easier that cutting the tricky EGR bolt. I was glad I went this route. Removal was fairly easy and re-install not bad either. Only issue here was the bottom alternator bolt (on install and removal) was partially blocked by lower radiator hose. Again a helping hand here to push the hose down out of the way would help. I made due by pushing it down with an unused ratchet and kinda crammed it out of the way. Re-install of the alternator took a few minuted to get the bolts lined up and threading correctly but easy once that was done.
Alternator out of the way, install EGR super easy.
MAP Sensor, little mother f-in map sensor. This was the hardest part for me. I'm not super tall, 5'10". Being 6'+ could help this a bit. This little bugger is crammed way in the back of the engine bay, very hard to reach for me. I had a hard time finding it initially, a thread on this forum helped me. Then unplugging the electrical connector was a bitch. I used a long flat head to push the safety pin out (from the passenger side). I actually accidentally pushed it all the way out and lost it. Then I threw a towel over the drivers side fender and leaned all the way (feet off the ground) over the motor, pushed the safety down on the plug with my left hand and gently tugged on the wire/plug with my right. This was a fight, took me a very long time to get it off. After that I had no problem breaking the 2 tabs, rotating the MAP and installing the new one, reconnecting all. I got the old sized one from advancedauto.com. I had no issued with size getting back in, was identical to the one I removed. I think the manufacturer was BDS.
Next was the plugs. I've never done this and was frankly terrified of breaking a plug, stripping something, etc. In all honestly, on the 08 at least with the tools I bought, this was super easy. I was slow, gentile and patient. My plugs (at 50k) had probably never been changed and were filthy. I took all coils off and plugs out on one full side of the engine at a time. Made it easier than doing one coil removal, then one plug removal, one coil removal, one plug removal. Didnt have to change much between ratchets. The I gapped (first time doing) the plugs per the spec. and dabbed on some dielectric. Threaded them by hand then torqued to spec. Re-install of everything went smoothly.
Installed billet catch can, no problem. Had to get some longer hose and made the firewall bracket as described in another thread on this forum. Looks very nice. I'm gonna paint the bracket black. Just wanted to get it on for now.
Putting things back together went fairly well. Like i said getting the alternator to line up and thread was a little tricky, a friend here would help to hold it in place while you bolt it. And the belt, again a friend to hold the tensioner loose while you slip it on the last pulley would help. but i got it done, slowly and patiently, more importantly safely.
Time to fire her up! Uh Oh, rough rough rough idle, check engine lights, bad noises. Shit, bad parts? Did i forget to tighten a plug?....
Nope... Didn't re-clip on of the connections on a coil pack. And didn't plug in the sensor of the air box tube. Unhooked negative battery terminal, connected all the things I missed, waited 5 minutes. Started up strong, codes and lights gone. Ran great. Took it for a 30 minute drive and got some victory slurpees. Coke & Pina colada if you must know.
The last little issue came with my oil change. I bought the mopar kit which came with the Mopar oil filter, I bought a cup type wrench that fit that filter. Well whatever cut rate budget oil change the dealer had on my truck installed a filter with a circumference about 1/3 less than my filter, so my wrench was useless. I went and got the right sized wrench, they are only a few bucks, and got it off. Mopar filter installed with no problem.
Now all done officially. Ride seems smoother, and more powerful. Not by a whole bunch but I think i can see some differences. I'll report back on MPG soon. I was getting about 8.5 city (mostly all my driving, new hemi, heavy foot) 13.5 highway (really only did about 100 highway miles so far). I'm not expecting much, I didn't by this car for fuel economy although my WJ only got 13.8 combined MPG, so I'm used to bad economy. Plus I only drive about 2.5 miles round trip Monday to Friday commuting to the train station. The engine seems to sound a bit throatier, throttle response seems a little better, but this could all be placebo effect because of how hard I worked and how much I wanted to see drastic gains and improvements.
I failed to check my tensioner pulley and all other pulleys, I have a constant squeak that I wanted to address and I forgot. I'll get back in there soon. I can deal for now.
I also have an exhaust leak I need to address. Still deciding on a good muffler (Corsa, Gibson, Flowmaster???) and I'll have it installed and leak fixed (hopefully) at the same time, again, I can deal for now.
Hope this can help someone in some way. If anyone wants pictures of anything specific, like a bolt I mentioned or a location of something let me know and I'll get them.
Next is installing a LED conversion kit for the interior lights, should be here tomorrow.
After that is recovery points. D-Ring Shackle Mounts in the front (im going to paint the brackets black, the D-Rings red.
2005 2010 Jeep Grand Cherokee WK Front Tow Shackle Mounts | eBay
Rear factory tow package with D-Ring. I'm not gonna bother with the wiring for now, I don't plan on actually towing. Just for recovery, bike rack, cargo tray, etc.
Then comes the lift. It's going to be RC 2" Budget boost, Billstien HD all the way around, 1.25" spidertrax spacers, Goodyear Duratrack 265/70/17 on my Factory Everest wheels ( I love their look) & pinch weld mod.
I have a Rola Cargo Basket (from my WJ) that will be mounted when I get the lift also.
I'll keep everyone posted with progress.
