    Looking for a turbo setup for a 6.9 / 7.3 idi

    for 9-10 lbs of boost the head bolt issue is a non issue with modern headgaskets also there is a thing called head studs you know ARP if you stud a 6.9 and decompress them can run around 25lbs of boost and not pop head gaskets on a 6.9 just so you know I am no noob to these engines but am...

    1990 F250 good fuel pressure no start.

    have you tried pull starting it if its a manual and if not might try WD40 down intake and a rag with small amount of gasoline on it in front of the air breather to fire it off and run it long enough to prime system other than that block the bypass port of the filter housing that goes to the...

    How hot is too hot?

    yes I blocked the bypass behind thermostat and removed the check ball in the thermostat neck so always have a steady amount of fluid bypassing to the radiator so no air can build up once our engines are warmed up the thermostat never fully closes it always stays partially open. So pressure...

    This does not look good

    a simple hand held wire brush will remove it the thing he needs to worry about is making sure he adds the friction modifier and the synthetic 75w-90 gear oil and of course re sealing the pinion and cover.

    This does not look good

    okay first off replace the pinion seal and reseal the cover and fill with 75w-90 synthetic gear oil and add the friction modifier to the gear oil you have a trak lok which is a posi lock it has a clutch pack on both sides of the spider gears to me it looks like you simply had some moisture in...

    I Need Piston Rings

    o.040 is going to be difficult most are now 0.025 then 0.050 the hastings 0.050 part# is 2D569350 and that is the good set with same first and second ring gap not the one with the 2nd ring gap of 0.060-0.070 https://www.hastingspistonrings.com/wp-content/uploads/2020/07/diesel-catalog.pdf look...

    IDI Guy Stumped

    I bet with the new pump your getting more pressure faster and at higher lvls than the old one causing injectors to pop early alot of hot pumps do this but stock they do just fine been there done that pull the injectors pop test them and set them to 1750psi-1850psi I like 1800psi myself for...

    Running hot and losing 1/2 gallon of oil per tank of fuel

    the blowby is why i say not likely turbo a turbo wont make blowby unless you have a leak in the system aka rings or piston is only way it would cause blowby or a blown intake gasket blowing boost directly into crank case but these motors dont make boost idling so only place blowby can come from...

    Running hot and losing 1/2 gallon of oil per tank of fuel

    if you got that kind of blowby you either got stuck / broken rings or a cracked pistons these motors cannot take the fuel / heat like a direct injected diesel our motors run super high compression and our pistons are cast pistons without a steal top so they swell in the bore when get hot and...

    Starting fluid: how bad is it really?

    I have used a small handheld propane torch many times light it up set near inlet of intake and crank and off she goes and if is really stubborn just use propane and no flame let it run for about 15-30 seconds into the intake then crank and usually off it goes the additional heat helps start the...

    Bronco Fuel Tank Install

    You can return directly back into the feed line I do this to help with fuel filter warming in cold weather along with simplicity and my feed fuel temps never go over 125f so it seems to work well been doing it for years on many of my builds so there is no need to return to tank honestly and for...

    Bronco Fuel Tank Install

    I would have to look back in my posts in past I linked all the info before makes models you name it but currently dont have the time to do so got a crazy project going that will likely be very special in our IDI world. you can get replacement gasoline ones for these old fords just got to...

    Help!!!! 6.9 won't start!!

    Dirtydiesel21 I bet Lifters when you took it apart I bet you left the lifters un tensioned and they locked pumped up from theyre internal spring pressure this is holding valves open when they should be closed. I just went thru this myself on one of my motors and I am here in florida where...

    How Many Flats??

    When you ask about how many flats alot is at play at what elevation / what Injection pump model & version ( reason being high viscosity or low viscosity version flow much differently on modern diesel) / then condition of your injectors ( aka pop pressure and are they leaky or not along with...

    1994 7.3 IDI Squealing/whirling Turbo

    I advise a simple rebuild of injectors or atleast a pop test and calibration can get the pop tester for like $70 on amazon or ebay and it is simple to do the resetting of the pop pressure via reshimming the injector nozzles you want them within 50psi variation between them and OEM is 1750psi pop...

    1994 7.3 IDI Squealing/whirling Turbo

    Yeah the turbo isn't really making much noise outside of the norm from my experience but I did here a bit of slobbering like you might have a lack of compression on a few cylinders and this could be a injector issue aka bad injector pop pressure or a few dribbling injectors outside of that it...

    Broke on the side of the road after putting in new tank

    Do you still have the dual fuel tank selector valve in the loop if so remove it since are using a single tank also I have had the pickup on end of sending unit in tank crack and cause a slight air intrusion issue if is questionable remove it altogether and use a piece of fuel line to replace it...

    How hot is too hot?

    when you crank up the fuel on our motors and go into mountains under hard load aka low air density our EGT's spike fast causing coolant to boil ( because alot of coolant in the head is used to cool the exhaust ports ) very often risking the thermal runaway. I have had this happen to 10 motors of...

    How hot is too hot?

    all motorcraft / international thermostats for our motors have the plug system hince why these are all us true 6.9 / 7.3 idi guys recomend is the motorcraft / international thermostats for this reason but this system can fail us when steam and air are in the mix due to flash cooling causing the...

    How hot is too hot?

    That myth has been proven false coolant cannot flow to fast for the transfer that is a old wise tale regardless the same amount of heat is transferred albeit at a faster rate when the flow is increased the old wise tale about coolant moving to fast thru block and thru rad is false that has been...

    How hot is too hot?

    The heater core is a bypass and the upper rad hose housing above the thermostat is a bypass also so it isn't a complete bypass and the issue isnt the Tstat blocking it when its open its when steam aka a overheat come into play causing the thermostat to close due to flash cooling the back side of...
