    Blow by coming from beneath turbo.

    I just did head gaskets on my idi, and now there appears to be blow by coming from underneath the turbo. It also looks like the pedestal may be leaking oil. ATS turbo for those wondering. The grommet in the valley pan was replaced. Not sure what's going on here. Any thoughts? Maybe just the...

    How do you remove an ATS 093 turbo?

    I have removed the turbo bolts mounting it to the pedestal. I have removed all but two bolts to the down pipe elbow. I have removed two bolts holding the up pipe on. I cannot remove the last 6 bolts to get the up and down pipes off. The two on the back side of the up pipe, I can only get a...

    Pushing coolant out the overflow.

    Well, my truck runs great, but it's pushing coolant out of the overflow, and will overheat because of that. Truck has a new water pump, and I replaced the radiator cap just out of curiosity. Didn't change anything. The coolant system pressurizes instantly after starting. There is no cross...

    Truck cranks slow after sitting.

    After sitting for a few days, my truck well crank really slowly. Still starts great, just sounds like the starter isn't getting full voltage. Maybe an off key draw?

    Coolant leak.

    After fixing the coolant leak at the upper radiator hose, I have another leak. This time, the coolant is dripping from the oil pan, and seems to be coming from somewhere below the heads. The oil cooler is wet, but I'm not sure if the coolant is coming from there. So my thoughts are it...

    EGT gauge weirdness.

    A little while back, my egt gauge Started to randomly drop to zero while running down the freeway. A quick thottle blip would make it work again. Now, It will drop to zero if i get on the throttle. It's a gauge marked with ats on the bezel. No idea on the brand. What could the deal be?

    Leak from upper radiator hose on the thermostat housing.

    Has anybody ever cracked their thermostat housing? I put a new upper radiator hose on my truck when I replaced the t stat, and now it's leaking down the housing from the hose. I'm going to take the hose off tomorrow hopefully (it's cold here) and clean it with a scotch brite pad, but I'm...

    E4OD slow take off.

    When I first start the truck in the morning, I put it in reverse, and push the throttle, the truck moves, but almost like it doesn't have the normal amount of power. If I let up, then go again, the truck moves in reverse normally. This only happens when it's cold out, and I wonder if the...

    Water injection vs. intercooler.

    So at this point, I want to add either an intercooler of water injection. I've read a little on the subject, but I was hoping to get some information from those who have experience. If I were to do the water injection, I'd likely do the splash system from the article here. So, I'm...

    EGT Behavior.

    So whenever I search EGTs, I get a bunch of discussions on what is considered max, sometimes including cruising EGTs. This is useful information, but I would like to know something different. What happens to your EGTs when you pin it to the floor from a stop? What are your EGTs by the time...

    IP turned up.

    I turned up my IP today. Two flats. Yes I have a pyro, don't worry. So, for testing purposes, I tied my wastegate shut, and ran the truck unloaded. I had to work to get it to break 9 psi of boost, and 9 was all I could squeeze out of it. Turned the pump up, major difference. The truck...

    Coolant temps.

    I finally fixed my upper radiator hose leak. First it was leaking around where it attaches to the thermostat housing, new hose and cleaned that up. Then it started leaking at the radiator. Turns out the paint on the new radiator was flaking off, causing sealing issues. So I pulled the hose off...

    Where to go from here.

    Alright, I've got a pyro that reads from the crossover pipe just below the flange of the driver side manifold, I've got a mechanical boost gauge attached at the intake hat. Gauges are covered. Truck is timed to 8.4* using a kent moore meter and the pulse method thanks to JohnZ. Unloaded...

    Park to drive without brake pedal.

    I noticed today that I don't have to press the brake to shift into drive. Were these trucks just this way, or do I need to fix something? I could just imagine my wife running something over because of this. LOL

    Idiot added SCA without testing.

    So, a friend was asking about SCAs today. Told him about them. Mentioned I likely needed to add some. Failed to mention test strips. Well, this guy grabs a bottle of VC8 from the local ford dealer, and adds it to his coolant without testing. I know this isn't a good idea, but does he need...

    Boost gauge sender sealing.

    I'm about to install a boost gauge, and I'm going to install the adapter in the snail of my ATS turbo using the plug that's there. My question is, should I seal the adapter somehow? If so, what should I use? Probably a stupid question, but I can't find the answer.

    Revised junkyard cowl intake.

    Ok, I posted my first cowl intake in another thread. I used dryer venting and it was ugly as sin, and not very servicable, as removing it would crush the vent. The original below. I really like the cowl intake, so I went to the junkyard and found this. That's the intake hose from a...

    Cowl air intake.

    I built an intake similar to the hypermax intake today. Man, what a difference. Better throttle response, feels like more power. But man, cutting the hole for it was a pain. I cut a 4" hole to the passenger side of the brake booster with a hole saw. Darn spot is not flat. Anyway, used a...

    Flashers stopped working.

    All four flashers stopped working today. Brake lights and everything else works fine. Might mention that when I am stopped, turning on the flasher turns off the brake light. Also, it seemed the signals flashed pretty slowly prior to this happening. Possibly the flasher relay? The hazards...

    Hex plug with spring in master cylinder, what is it?

    There's a hex plug that goes into the master cylinder, that the rearmost line connects to. What is this plug? And how in the world do you install it? Seems like it sticks down in the piston bore on the new master cylinder, can't seem to get it installed.

    Injector wont thread in.

    So, I'm replacing an injector due to the old one cross threading, and the new one starts into the threads easily, then stops. I haven't tried going beyond this, but it definitely isn't all the way in. This doesn't seem normal, but I don't know. Maybe I have the washer in there crooked? I...

    Leak keeps coming back.

    I did a return line kit on my injectors. Finally got them all to stop leaking, then take the truck today, and it started leaking on the two injectors closest to the cab. This is after two days of chasing down leaks, using two different sets of o-rings. I lubed them with motor oil when I set...

    Poor mileage.

    I have only managed to get as much as 12 mpg in my truck so far. I have so far changed a filthy air filter, and replaced the fuel filter. The truck runs fine, isn't really lacking for power, and the EGT gauge doesn't show anything abnormal according to the forum. I also drive the thing...

    New to me truck.

    Just bought this 1991 F350 with an ATS turboed 7.3 Here's the only picture I have of it. It does not have the camper on it though. It has an EGT gauge, but I think a boost gauge would be helpful as well. I guess the EGTs run just shy of 400 degrees during normalish driving. Not sure...

    Which ATS turbo is this?

    Going to be buying this truck in the next few days. It's the 91' I had mentioned in another thread. Crew cab, long bed, 4x4, ATS turbo. Anyway, I'm curious which model ATS turbo kit is on this truck. Here are some pictures. (Full size for detail.) Also, what is that little...
