      It's above the oil level about 2 to 3 inches in the upper part of the windage tray. Next to the oil filter. I may just drill and tap the oil filter and be done with it...LOL

      The problem was getting a drill in there.

      The pipe thread with an o-ring may work? hmmm

      Doubtful. There will be no real shoulder for the o-ring to rest against in the fitting. And there will be no recess cut into the pan metal to allow the o-ring to seat inside and press-fit to a good seal.

      If I were you I would just use some RTV on it. Take the fitting out,splotch some RTV on the threads, and tighten her back in. It might be enough to take up that little extra space and seal the leak. After all, according to your fitting placement, it should be more of a passive leak than a persistent one.

      It doesn't leak when cold or just idling. I went for a 5 mile trip, then crawled under to find a good bit of oil, so it's when I'm driving and the engine oil is warmed up. Can't hurt to try RTV. I guess I'll take the fitting out, clean really good, and re-seal with RTV. Good idea.

      Hind site is 50/50...Using the below would have given the room to do this right. I guess, if nothing else works, I could go to the next sized larger and use a right angle drill attachment to get it straight.

      That's about what my eyesight is now, 20/50 or so.

      Try the Ultra black or copper and see if that does it, I love the stuff.

      The RTV slowed the leak down but it's still there. I thought it did the trick but once the pan heats up the leak starts agian.

      Maybe it did work. After letting it cure for 24 hrs (opposed to 12) I'm not seeing anymore oil. This may of done the trick.

      Rob - I know logging is the best way, but to tell the difference between spark blow-out and detonation, can you examine something (maybe plugs) or know which one it is if I describe the symptoms?

      Basically, at around 3500 @ WOT it's starting to cut out and loose power. I ofcourse get out of it quickly but It doesn't sound like the detonation I've heard in the past. If it is spark blow-out, what would I look for?

      Yeah that RTV takes a while to cure fully.

      To determine what you are encountering I would take your existing tune and drop a bit of spark advance out of it so you know it should not be detonating. If the engine doesn't cut out anymore then it is likely to be spark advance related. If it still cuts out then I would pull your plugs and gap them a bit smaller. If this takes care of the stuttering issue then you know you got it figure out. Then from there I would just methodically add spark advance back into the tune until you start to chatter the valves a bit and then back the timing off a few degrees and set it at that.

      What hardware or software changed in your combo between when it was running well a year or so ago and now that could cause this issue to arise?

      Small changes only. The PCV system is now tied back into the intake pre-turbo in an attempt to create a vacuum to help rid the crankcase pressure. The actual PCV side of the system goes thru a oil-separator then into a oil catch can. The side that use to hook to the stock intake is now going into the same oil catch can. The catch can is connected to the intake pre-turbo. I don't see any traces of oil in the system yet; even the catch cans.

      The pipe section that connects to the turbo was cleaned up (ported). It had a bunch of welds in the exhaust flow before, Especially the waste gate side.

      The back wheels are wider and heavier…not sure if this changes the load enough to make a difference. I can say that it didn’t really help the traction problem. It’s now just a heck of a-lot louder spinning.

      The gas may still be contaminated from sitting for so long.

      Also, it appears I'm running 1 more pound of boost (for a total of 10). Either the crack in the intake (which I fixed) or the cold weather is causing it cuss I didn't adjust it yet.

      I want to run 12 lbs in the future.

      Can the factory fuel system support what's needed for your current turbo setup? As in, do you think maybe it's starving of fuel when you go WOT around 3500rpm? Just a thought.

      Naw, I'm running a walbro pump and 42LB injectors.

      When I get off my rear and log, i'll figure out what's going on.

      Well get off your rear and getting to logging darnit!!!

      Once you get it running good, I'm going to take another stab at what you'll run;) I'm thinking 13.1-13.3's with the little work you've done, but I'm not sure what all you've done.

      I got 4 idle logs and 2 no load rev logs done yesterday. The LTFT was greater than 25% off. I'm not positive why cuss I didn't think the changes I made had that much of an impact. I'm thinking It had to of been the PCV being in a metered system before and now completely separated from the MAF metered air. That and I probably tuned to the intake leak before.

      It's good now and I'm going to spend a lot more time getting the tune nailed perfectly. Not just the WOT part but fast revs, drivability tuning, and more tranny tuning. There’s almost always room for improvement in a tune.


      HAPPY HOLIDAYS EXPLORER FORUM!!!!!!!!!

      Another 8 logs done and it's dailed in pretty well. But I most say, when the pump stopped, oil got in the piping, which then got into the intercooler, and I refuse to take all that piping back off to clean. I've had to clean the MAF 4 times and I think most of the oil has blown out. It's just a pain when you get oil in the cold side cuss of it getting on the MAF wires and skewing the numbers.

      I'm getting some weird readings up high at WOT...For a minute, I thought I had pegged the BA2600 Meter but found out it was a skewy number. I'd like for someone more experienced to view it if possible. Let me know and I'll post it.

      My suggestion is that you take the time to clean your piping out. After all, how long is it going to take? Probably a few hours at the longest. At least that will eliminate one more factor in what could be causing your skewed readings.

      I'm fine tuning the timing curve, and during this process, I've for sure made the valves cladder. The first time I tuned, I never got the valves to cladder before calling it quits. This time I kept going until I got the noise, then backed out.

      The AD counts are running up higher than ever (900 range). The load is reaching 1.8 to 1.9

      It's running good. The drivabilty is great. It feels as if it pulls all the way thru the RPM range and doesn't feel like it's falling on its face above 5000 RPM.

      Also, any pictures of the new wheels?

      I've only got the back ones on at this time. Money was low so I skimped and purchased used tires for the front. Went to have them mounted and found they were dry rotted. So, i'm waiting for the right time to buy the front tires.

      I'll see if I can get a quick video up soon.

      Just had a coupler blow off @ WOT. Imagine trying to listen for ping and then hear a burst sound. Excuse me while I change my pants.

      Yes, there is one place where the end of the pipe doesn't have the rolled lip to stop the coupling if it starts slidding. This is where it came off but an easy fix. I was up around 11 lbs when it blew so that's part of it. No problems

      so what did you end up doing for a bottom end? did you go with the custom pistons and sbc rods? im looking for a budget way of building the bottom end of my 94

      The bottom end is still stock. I wound up putting it back together to try and blow it up first, before I rebuild the motor. (j/k) Plus it cost alot and money is allocated elsewhere for the time being.

      I'm not sure there is a budget way of building this motor; it's going to cost. But I've managed to get it in the low 13's as is.
