Front mount guys, need input

[jetmech]

Just a quuick question about the 02 sensor situation with a front mount. I've seen so many people with ORY's and front mounts driving around with their check engine light always on. I know that the cats go away with a front mount install but is it possible to keep that damn check engine light from staying on with a front mount? I'm assuming it can be taken care of with the tune but I honestly don't know. I would go insane driving around with nothing wrong and have the check engine light always on. Thanks in advance.

no problem with o2's here since allen worked on the tune some more....

Oh ok. BTW, where is the best place to put the oil drain on the oil pan?

Front O2's being on doesn't relate to having a front mount. SES light from O2's are usually on due to bad O2's, wrong O2's, exhaust leak, bad wiring, wrong wiring, or with longtube headers, sometimes.
More trucks with longtubes have front O2's causing an engine light vs front mounts.
To answer your question, there should be no reason why you can't having working O2's with a front mount. The rear O2's can be shut off and the fronts still work.
You looking to move that turbo forward?

Yes sir

[bud8fan]

cool...you will love it...

[jetmech]

I'm counting on it

Yeah no O2 problem here either. Also, I have the oil drain located on my front cover right above the oil pan, only because I had it off at the time I was putting the cam in. The oil pan is always the best place though, right in front.

like ducky said, just to the right of the crank pulley, there's enough room for a fitting.
we use 3/4" hose for our drain, but i've seen small 3/8" work as well.

I'll be using AN-10 line for the drain.
Thanks everyone for all the good info
