I think im going to try the kerosene engine flush, pull the oil filter housing and clean it and the add mobile one with a oem filter. If that doesnt work i guess i will buy the .9 bar oil light switch to replace the 1.4bar thats in it right now.

 

Don't bother. The OEM, Bosch, Mann, and even Wix and Mobil1 replacements are cheap. No manufacturer uses K&N as original equipment. There is a reason for that. Although, I've never been a fan of K&N products...

 

Wait, you're trying to diagnose poor oil pressure and you have incorrect sensors installed?

 

Let's talk about this kerosene engine flush. I've heard about it, but I'm scared to death to do it.

What's your procedure for doing this?

 

I first picked up a Mobil 1 filter, but then I realized that AutoZone was running a special on any 5 quarts of Castrol Syntec and a K&N filter for $26.99....I figured K&N would have at least made a good oil filter.

 

But K&N doesn't make good anything.

 

Im still trying to figure out if i have a oil pressure problem or if the incorrect sensor was installed. It never dips below 15 and idle which i thought was fine but the oil light comes on a 25 psi when i start driving. I removed the old switch and replaced with the same part number. Wouldnt you think that 15 psi at idle was sufficent? I thought the spec for oil pressure switch was a little high and then someone mentioned on another forum about a .9 bar switch.

As far as the diesel flush goes it scares the hell out of me also, but a guy i know does it to his 70 something dodge truck and it runs like a top. Im still debating on doing this
