    Lb7 hg/injector replacement

    So I've got it on a stand and it's about to get worked on. I'm putting a rear main on it while it's out to stop that leak. My question to you guys who have done this before me. Can I reuse the exhaust plumbing gaskets? They look fine but idk. Also can I reuse any other gaskets other than hg and...

    I will let you know as soon as I pull the head. I've got it on a stand but it's dry here now and I do dirt work.. So it's on hold. I did pull all exhaust pipes and harness off and yep right hand bank manifold full of coolant.

    @dirtymaxo3 I may need a set after I smacked my #8 piston and hydro locked it. I tried to move it 20 feet to the lift. Man I hope I didn't hurt that rod. It was stil locked while I was removing the converter bolts. Locked with normal rotation the last few degrees but turned all the way...

    Lb7 drinking coolant

    Holy crap my list just got long. It also has a leaking rear main I've been putting off and will do it now. My next question is should I just pull the engine. I have a twin post lift in my shop to make removing the trams much easier for rear main install but with all I now face it may be easier...

    Lb7 drinking coolant

    Water in oil at all that's what is strange. I guess if it's a head gasket the location of the leak could be away from the oil passage. I'm tearing it down today. I'm putting all 8 injectors In and have been looking at so cal diesel standard flow Bosch. Any suggestions on injector type?

    Lb7 drinking coolant

    First I will say I've been reading for hours on here about injector/injector cup replacement. I've learned a lot and will repair myself. Still things are still bothering me.. What I have is an lb7 with 320k miles. I first noticed raw fuel from exhaust. I figure stuck/broke injector. Next it...

    Lb7 primer pump rebuild

    I have had an issue with loosing prime from time to time. While using the hand primer the other day I noticed diesel and air bubbles coming from under the pump assembly between the filter housing and pump. After disassembly I see that all I need is the one o-ring that seals the plunger to the...

    01 2500 6.6 A/C charge capacity

    Thanks. Yes I have a vacuum pump and gauges. I service all our equipment and trucks. But peterbilts hold 3 to 4 pounds! I usually watch the gauges on big trucks if I don't know the capacity. 250 on high side is cut off or cuts on fan then down to 75 or so gets it pumping again. I've just never...

    LB7 leaking like a Detroit..

    Well the main reason I think it's the rear main is because oil drips from the bellhousing. But I will double check because ANYTHING is possible. Also oil is looking as it should, reasonably thick, black, and no diesel smell. Also oil level is not increasing. It drops pretty fast from the...
