    Freeze plug tool

    Justin from R&D IDI Performance uses a modified hole saw to convert the block from the disc-style freeze plugs to the cup-style kind that can be driven in with a socket or anything. Here’s the video where he goes over the process if you want to go that route: (Freeze plug stuff starts right at...

    IDI marine engine questions

    I haven’t dug into it yet since the initial inspection, but I’ll definitely check the piston part numbers to verify whether I can use them. I did see the boat and it was a single engine center console, hopefully that means the engine spins the right direction.

    Showerhead filter alternative?

    I’m 90% certain that the ohms range on the sender/gauge is different on the bullnose trucks than it is on the brick/aero nose ones. I think the 10-73 ohms is only for the earlier trucks

    IDI marine engine questions

    I went and picked it up today, and there’s good news and bad news. The good: - The guy had the heads gone through and resurfaced before he discovered the cracked and irreplaceable exhaust manifold, so I have a good set of heads! - I got a parts manual for the marine IDI engines, so I can...

    Fresh build, smoke, stumped

    That is interesting about the required fuel pressure at the pump. The Stanadyne DB2 manual calls for “greater than zero” to 5 psi for a stock pump, but I know the govt manuals for a HMMWV call for 4-8psi like Justin does.

    IDI marine engine questions

    I reached out to the guy and if all goes well I’ll go pick it up this weekend. I’ll check any part number I find to see how they cross reference.

    IDI marine engine questions

    That’s what I’m thinking too. This is a really good point, I will try to find out. Thanks for the good points guys, I’m leaning towards picking it up.

    IDI marine engine questions

    I came across a 7.3 IDI boat engine locally for $250. The guy is selling it because the water-cooled exhaust manifold cracked and apparently they are impossible to find. I’m interested in building an engine to drop in my truck, but I want to ask the group whether it would be a mistake to pick a...

    “Need help using my DTI 3300s timing meter on my 6.9 IDI.”

    The only way I got the probe to work was to jam it all the way in until it touched the balancer. When I let go it sprung back a tiny bit so it wasn’t actually touching, but ended up as close as possible.

    Return line question

    I forgot to add that there are other olive seals in the fuel system, so you might as well replace them all. Russ (Russrepair.com) includes them in his return line kit, but I can’t remember if he sells them separately as well. I bought viton ones when I did it instead of standard rubber. Look up...

    Return line question

    That fitting is different depending on the year of your truck. If it has a steel hard line leading from the IP return to that fitting, you will have a rubber “olive” seal that is supposed to seal the connection. There’s a good chance that olive seal is cracked and old (mine was hard as a rock...

    Power Steering Pump

    Gandalf, have you checked to make sure that your rear brake shoes are working correctly? There was a thread a while back about how many of them were cast incorrectly, causing them to only slightly expand and not grab the drum with enough force to provide stopping power. I ask because I swapped...

    Oil change for ZF-5 Transmission

    I dug up Redline’s technical information sheet, which has some good info for those curious. Here’s the link: https://www.redlineoil.com/Content/files/tech/Manual_Transmission_Tech_6.20_.pdf Here’s a quote about MTL’s similarity/differences to Dexron 4: “In transmissions which recommend...

    Oil change for ZF-5 Transmission

    I used to advocate sticking with ATF since that’s what Ford recommends, until I found out that ZF-5 transmissions are actually used in many other vehicles all over the world. They’re even in Chevy trucks down in south america. ZF recommends their own fluid called “ZF Ecofluid M” which is a...
