So this past week, the wife comes in tells me the check engine light is on in her 2013 Jeep Wrangler (3.6L pentastar, 6 speed manual transmission). Mentally I'm grumbling as this completely destroys my plans on spending the next couple of days on range. I take it down to the local auto parts store to see what the code is.
Oil pressure switch/sensor, or intake /pletanum gasket leak is what it comes out to. For those not familiar with the engine, that switch / sensor is located in the oil cooler/oil filter housing on the top of the motor under the intake, and pletanum (both are plastic molded).
I'm not a automobile mechanic, but I've always been able to keep my vehicles running, and back in the days when it was actually affordable to do so I have rebuilt a engine or two. In the past I have pulled the exact parts off to service/replace that oil cooler. So this wasn't my first dive into this, and was easier than the fuel line that my daughter and I installed when it cracked leaking fuel unto the manifold. Which again same parts come off to fix.
(that one the wife asked me if she could keep driving it? I asked her if she wished to burn the Jeep up. Her eyes widened, hot manifolds, engine blocks and fuel not good combination = engine fire).
Well I didn't think the best strategy would be just to replace the gaskets and see if that was it, with the chance of having to re pull everything to put in the switch / sensor. So sensor / and gasket set. Gathered up the parts, go to the house which was late evening so I just pulled every thing to have access to the switch sensor. The longest tasks was disconnecting the fuel injectors, and the oil pressure and oil temp switches. While not breaking the fuel lines and other connectors. PITA to say the least when one is trying to be careful. once I flipped the intake I seen where this was probably the culprit, gaskets was actually recessed in some areas. OK no problem I think so I set in went to pull the sensor crap special socket. So back I go to get the correct socket, pulled and installed without issue. Set everything back in. Because of my aging years I've lost much of the ability of strength/agility in my hands so I pulled my daughter out to help when I just couldn't reach things. That greatly enhanced the project her skinny hands could get to the areas I would struggle and cuss at.
So I set about cleaning all the mating surfaces installing the new gaskets, Lining everything up, go and grab my wheeler engineering FAT torque wrench to torque the manifold down (15-20 inch pounds is the torque value). Torqued everything down, (then I repeated the exact same error I did last time I pulled those items. failed to connect the vacuum hose to the master brake assembly un beknownst to me at the time).
I fired it up and it throws a check engine light after idling a while, run it down to check the code comes back egr valve. The kid that ran the code goes in, to find the part I stop him ... look that motor doesn't have a EGR valve. It has to be a hose, finally we find the hose reconnect. Bingo success. no check engine light.
The point in all this wasn't to brag on the skill set /knowledge to fix this, nor anything other than in my later sixties this whole process hurt. It didn't matter that I had the know how to fix it. But the pain level today is up there a bit.
My wife said to me I know you still love me as you could have said "Good Luck with that", my response is honey that day is soon coming, there will be a day when I simply can't physically do that any more.
This realization for me is rather a downer to say the least, as I hate the fact that my disabilities are now taking a toll on such activities... Not that I can't do most things but the knowledge that it won't get any better.
Before too much longer the brakes will be due service, That I can still do without much pain as I can get it high enough to actually work on without much pain.
