Thread: Regrounding the O2 Sensor

DINO oil probably clogged the squirtes up.. I changed to Mobil 1 about 3 years ago but they were probably partually clogged already.. Its amazing that the detergents in the Mobil 1 didnt keep them clean!! Am I wasting money on Mobil 1??

Oil Squirters.. They squirt oil at the top of each cam lobe for lubrication of the lobe, and surrounding parts.. Their is 2 squirters per lobe for each cam, giving you 8 squirt holes on each side. For the Intake Cam, I had a grand total of 3 squirt holes open (one on lobe 3 and both on lobe 4, lobe 1 & 2 was starving and are now pitted/deterioated from heat buildup). For the Exhaust Cam, I had a grand total of 2 open squirt holes (one on Lobe 2 and one on Lobe 3; amazingly no damage but normal wear). You should change the Oil Squirters every 100k miles (major tuneup). I didnt..

Yes... I know it has nothing to do with it... But, I didnt want to gunkup another O2 sensor with possible exhaust crap until I fix the problems...
I will reinstall once done with my other repairs...



Yep, I forgot about your setup.. But on the SR20DE with EGR blockoff, I thought the ECU would trigger a CEL if you removed the EGR/Canister solenoid. How did you get around it?

Took a look at your build and YES, you do have a very very nice build... Making me thnk I should follow your lead!

There is a resistor that you can use to fake out the egr just like the rear O2 fake out, Thanks Vadim, its been working great.

I know the pain about the squirters... most of mine were VERY clogged at 96k miles, nothing diesel and pressure pushing it all then out.

Hmm but does Mobile 1 have detergents? If not then it wouldn't do anything hehe....



Ahh nice

Alright which resistor did you use for the EGR?

Here is a thread about it, but its a 100k
ohm resistor. If you go to the old forum and search under EGR removal you will get lots of threads.

Hmmm. I didn't get a light when I took all the EGR crud off of my '92. Maybe it's an OBD2 thing?

^It is...........

Sweet thanks

I just reread this thread and came up with a noob question. do you think this mod is obd2 specific or will obd1 cars see similar benefits from going to a 4 wire if they have the ssac? I'm guessing it's going to be the same but would like the confirmation before dropping the $60.

^Not a noob question at all. It is a good one that hasn't been asked. I just think it is a ground issue in general. No matter what car it is. If it doesn't get a good ground, it want get a good reading. It's a lot to factor in even if the O2 does work properly. Maintenance, weight, driving habits, and some MODS will play a factor from car to car. Everybody definitely want get the same results. We are just looking for better results on gas mileage to help fight against the rising prices.

+1 then for this being a benefit to obd1 as well then?

A better Q for me might be will a calum obd1 ve ecu on a swapped VE with a ssac benefit from this mod? Again I'm guessing yes. I've done the ohm check thing per instructions although my $3 harbor freight meter says there's no difference (when it works that is). I'm guessing my equipment is sorry enough not to be able to register the differences
