thats one way, to me its a last resort. I've used a dremel with drill bits chucked in it, picks, and pretty much any implement you can think to get purchase into the body of the thing, its miserable. Once you get the surely hard as a rock o ring out of the hole you remove one of the major things that will hold you up

The dia of the sensor body would allow the sensor to slide in & out without effort, it's the O-ring that would hold it in place. As long as one can get a grip on what's left to rotate it back & forth it will release.

Intercooler is installed we had to do some fab work to make it dual pass. Blow off and wastegate installed, just finishing touches and it’s tuning time.

Could it be done? I've been sorta looking for either a 3.4 or a 3800 series 1 to swap into my Lumina. My dad told me the 3800 is a strong and reliable engine. The only OBD1 3800 engine is from an early Regal right?? Would a 3800 be able to be swapped into my Lumina, and use most of the same wiring and same transmission (4T60)? I've also been looking at possibily doing the 3.4 swap, but (I'm not trying to satrt a flame war) I'd like a little more reliable engine. I know my 3.1 thats in there now is probably the most reliable egnine I've owned, and I'm thinking the 3800 would be decently reliable as well. And no, I don't want to do the #800 Series II Super charged engine swap (L67 right??) just because I don't want all the hassle lol.. So, any insightwould be helpful, and I might start shopping around for a nice series 1 3800 with decently low miles on it. Thanks! - Jeff L.

The 91-95 L27 (3800 Series I) put out 170 HP and 225 lb/ft of TQ. You could always swap in an L36 (3800 Series II) and use the wiring and computer from, say, a 91 Regal with the L27. The L36 puts out 200 HP and 235 TQ, and will run on the older L27's OBD-I computer. IIRC, the L27-equipped Regals received the 4T60-E starting in 91, so you may want to swap in an "E" tranny to go along with that L36 (the 96 Regals could be equipped with the L36/4T60-E combo, but had OBD-II.)
