Simple fix in the cab that eliminates a bit of the slop. I heard of this before but never done it. Then stumbled on this short YouTube video…

My nephew has the 1986 6.2 k2500 and handshaker transmorgifier. the occasional trail is the worst of it the truck should get. Even mix of city/hiway driving and he doesn’t try to go fast. No towing to speak of, occasionally (once a year for 30 miles) a car trailer with a pickup on it. It’s...

Looking for a pic to help a guy, I stumbled on this video. Anyone interested in dual alternators ought to pull all the part numbers off this video and save them. It might be a good idea if someone writes them down and posts them here somewhere in case the video gets taken down.

https://hummernetworkforums.com/threads/free-engines%E2%80%A6.250838/ So I spoke to Grayman. He met with a guy who owned a hummer business and is selling the lot of hummer parts apparently. None of the UROVA parts are there- all that was sold long ago. This would be more a reseller business...

Over on hummernetworkforums.com a guy with 6.5TD centermount engine is for sale. He blew a head gasket, one head toast, other one cracking between valves could be brass sleeved and ran 100k or so. The block is a May 99 so supposedly latest version GM ever made. You’d have to verify cylinder...

I looked, but am bad at finding old posts. It has been too many years since I was modifying these oil pumps. I know the stuff about die grinder work on the ports for under the 4wd adapter/ and the block itself getting the port edges smooth & rounded over. But I can’t remember or find my...

A few of us have made headers at some point. Incredible tedious. Time to look at the lowest cost kit how to make everything fit I have seen yet. Also would work for custom exhaust if they have the sizes available… https://www.centurialinc.com/exhaust-tech/starter-kit

Been a while since posting, and maybe this is something good to add to the “new guy check list” for them to learn. There is a million fuel additives that do different things. The one I recommend for the Stanadyne ds4 is the Stanandyne Lubricity formula in the purple bottle. Below I will add a...

If anyone has a block where you can post pics, or anyone better at google searching than me (almost everyone probably-haha) I would like to see some oil squirter pics please. I have my 99 van block that should have them but getting to that engine is a nightmare currently. Thanks!

My intent is to link together the most useful turbo threads for people trying to determine turbo comparisons into one thread rather for reference. Kind of a turbo sub thread in the performance section. If you come across any comparison threads you feel relevant, please add the link. A...

My nephew has lost his in the shuffle, any pictures of what this one looks like would help. if anyone has a spare layin around they are willing to part with it would be cool.

I never noticed we don’t have a specific thread for tools. Anyways- a buddy sent me a link to see this tool in action. An Engine hoist tilting tool. I am planning on building this one last engine and never again so I will not buy it. But if I figured I would still be doing more engines I...

I kinda like it. Never seen one quite like that before…

4L80E transmission cooling line bypass valve is a part all hmmwv and civilian Hummer, Hummer H1 have (idk about H2, H3). On hummernetworkforum.com the discussion about this valve came up. I never noticed it on any GM rigs, or anything that the 4L80E went into outside of a hmmwv/Hummer. It’s...
