Hey guys and gals, I just recently bought a 2005 Nissan Murano about a month ago. I bought it real cheap with a known engine problem and started a rebuild/engine swap. Here's some pics to get you guys caught up. 20190827_160327.jpg
What it looked like when I bought it.

  2. Used engine I bought, started tearing it down

  4. Full gasket set, Timing kit w/ water pump, brakes disc and pads, spark plugs.

  9. After tearing it down, going to be cleaning it and re-seating the valves. I'll post the after pics..

  13. Before anyone states the obvious, I caught the timing mishap and corrected it. It's now at top dead center..

So I have taking a break from the engine, I still need to finish the bottom part (timing cover bolts, oil pan). I did however start taking apart the front end and started removing the wiring, and parts from the engine.

She is messy.

Problem number 3: CV axle needs to be replaced

Problem number 4: the hose that is hanging in the front is for the oil cooler line, the fitting broke off. Hopefully i can just buy that and not the whole radiator.

Mishap number 5: sway bar link stabilizer nut stripped, had to cut it off.

Day One breakdown complete.
I skipped a day to recoup, come to find that the subframe had dropped about 7-10 inches. Sorry I didn't get pics of it, anyway here is where I'm at currently.

Here's the damage done to the harness nothing serious looks like the plastic only took a beating.

Was it running when you got the car?
Yes, however it sounded like the timing chain was really loose and it started to smoke really bad in about a minute of running. When that happened I pulled the oil stick to check, somehow oil was shooting all the way up the dip stick.

This is where it stands now, upcoming plan for this week is to remove and clean the accessories off the old engine and add it to the rebuilt one. Replace passenger side CV axle, replace both sway bar stabilizer links, replace front abs sensors. If all goes well this week I can start installing the subframe with rebuilt engine this upcoming weekend.

This is an interesting thread, and you're one of the few to tackle this. Dealing with the transverse engine and sub-frame is not for the first-time DIY type. Nice work so far, and I hope it turns out well!

How high would you say you have to jack up the front end to clear the entire subframe along withe engine and transmission from the bottom? Jack stands does not look like its sitting on the pinch welds. Can you measure it from the front pinch weld lift point down to the ground? Thanks.

Did you know the condition of the CVT before starting this project? Sure hope its running right. Good luck.

I've worked on cars my whole life, so I kinda know what I'm doing. However I will say say this is probably the most difficult engine I have ever worked on, I would not recommend this for a first diy'er to tackle a project like this. Everything is quite difficult to get to, there are allot of; plugs, bolts, parts, hoses, and specialty tools needed. Most frustrating is how they designed everything and placed it.

So if read correctly, you have a second engine and you want to scavenge the parts from the original engine to rebuild the second engine which also has problems?
The second engine was bought from a wrecked/totaled vehicle, but not knowing and seeing the condition myself I would rather rebuild it for reassurance. The current engine was said to have a knock, however I believe that to be the timing chain being loose and hitting the timing cover. The smoke and oil coming up the dipstick is a major concern, this maybe caused by a bad head issue or more likely bad piston rings. Either way I felt more confident just starting with something else.

For those who have not done it, there's no big trick to taking a running engine down and checking bearings, cam, cylinder bores, etc. It's all stuff that can be observed and measured. While you're at it, you can pull the heads and have the valves done if needed or the fit strikes.

Getting the engine in and out in the Murano is the REAL PITA.

That's one reason that when it comes to major maintenance I prefer vehicles with linear, not transverse, engines. If you really need to pull one and work on it, a car with an in-line engine is much easier to work on.

Pilgrim couldn't have said it better, the more newer vehicle models get the more complicated they are to work on. Think of it like this... Part A is not working its right there in front you, however Part A is somehow connected to part C but to get to part C you have to remove part B and it's on the back side of the engine blocked by part Z.... and so on and so on.

Welcome to the new world of compact CAD design. "Yes, we can get the bolt out, but we can't leave any kind of clearance to get at it...until you remove these three items!" They forget that there's a human involved, with hands. Got to love it or hate it!

Have a good day.

You said it. Just one example: to me, the height of insanity is the need to remove the intake manifold to replace the spark plugs or work on the back side of the engine. I realize that they were dropping an existing V6 into a new car body, but it's stupid to add hours of labor to a spark plug change or every day maintenance.

I can't single out Nissan, because my wife's 2009 BMW 328ix coupe needs a new valve cover. That's at least a 4 hour job with more wiring and engine parts to remove than I can believe. However, since it's an in-line engine, it's well within the capability of a competent DIY type.

Well finally got around to working on it after taking some time off, little catch up on me...
I got married, got sick, and then recouped. So to catch you guys up on what is going on with there Murano... I have removed the bad engine, the transmission, transfer case, from the subframe. I have added the lower intake manifold, fuel rail, rear exhaust manifold, and torque converter to the rebuilt block. On the subframe I have replaced both control arms and cleaned it up. My next step is to bolt the transmission to the engine, stuff that I still need to repair passenger front Abs sensor, top transmission sensor, passenger CV axle boot, extract and tap some bolts on the exhaust, and subframe.

Here are some pics of the progress..

Wow, the front subframe/front suspension member looks almost new, zero rust! Mine was almost totally rusted out after 16 years on the passenger side from AC condensate. Where did this car live? How many miles?

You sure are ambitious!

Your Murano looks very nice! I really enjoyed my 2003 for 16 years.

That's one thing among many I really enjoy about Colorado....there are no rust problems with vehicles that live in this state.
