    Is my problem using non-TTY head bolts

    lol, you mean you don't turn 90 degrees after they break right? yes ARP bolts aren't torqued to OEM specs on the 4.0 OHV cause there aren't any OEM specs for non-TTY bolts , but i thank you for the attachment. i had not seen that before. and yes i did use assembly lubricant if anyone cares...

    Is my problem using non-TTY head bolts

    Good to know. I did torque step wise initially, the re-torque was one step up, but only roughly 10 ft/lb. Given your info I think it would be reasonable to go to 100 lb/ft and re-evaluate. Thanks.

    Dipstick with 4.0 OHV with SOHC oil pan/cradle swap

    After finally finishing my 4.0 ohv rebuild, I am at the point of finally firing. I reused the ohv dipstick tube and dipstick and I suspect I should have done the SOHC dipstick. Hitting the full on the OHV dipstick & tube I believe is overfilled as it appears the rear main seal is leaks out til...

    I'm in the process of rebuilding my 4.0. I have the updated rear main seal and a low mileage crank in good condition, no scoring on the crank. Can I skip the repair sleeve and just install the new seal?

    rod oil squirter orientation

    slowly assembling my 4.0. there doesn't seem to be any clear direction on which way the rods should be installed. would seem to me that the rotation of the crank would dictate all the oil squirters face the same direction:icon_confused: wondering what people here who rebuilt have done. anyone...
