Been a hectic calving season around here, about all I got done on the Jeep was read, post some, and inhale parts prices and sources! I believe I finally have 'the' final list of parts ready to send in! Yippee. I guess I can go a year without health insurance. Still looking for my previously purchased Stage II kit, and motor mounts.. They'll turn up, someplace weird, like the glovebox I verified I do not have a cracked cylinder liner.. just a scratch that really caught the light funny. I used my SuperScraper(tm) to prep the block deck. I really love that scraper! It's a wood handled flat bladed scraper, with a carbide tip. It absolutely chops through rust and gasket material, right down to the base metal. Neat thing about it, even on aluminum surfaces, it's very forgiving. Almost impossible to get wreckless with it. If it ever gets 'dull', just send it in to the company and they'll put a new edge on it. Even brand new, it doesn't feel 'sharp'. My machinist was bragging his has scraped over 300 engines, and still has the original edge. Just don't drop it. Carbide is not shock resistant at all. I held the shop vac just ahead where I was scraping, and 99% of the debris got sucked up before it could fall into oblivion... or worse! I'll post the parts list and grand total soon. |

I've dealt with wood machining for a dozen or so years, so have some experience with carbide vs steel. There are various grades of both, but generally carbide is brittle and lasts 2-3+ times as long as steel before needing sharpened, but will never take as fine (sharp) an edge as good steel. Carbide is preferred for large long component runs for it's resistance to glue-line imprinting and long lasting edge, but shatters easily. For specialty items or small runs with exotic woods, knife steel is preferred to lower the possibility of wood grain tearing or splintering causing reject components. |

The cutting carbide, a 'square' much like a keystock, is brazed to the tool. It doesn't feel 'sharp', it's weird to explain! All I know it's the most durable, safe way (me and the parts) to 'really get it done' I've found! |

Parts are trickling in! Already had the rockers on hand, ARP's showed up yesterday. Waiting on; 'Good used head' (take-off from a warrantee/test/development engine) with very low hours. Been tested and checked. My machinist is swamped for another 2 months.. so this will have to do for now. Gates TB kit minus the water pump. They only offered the OEM version, and their aftermarket one didn't have some hole or boss for a bracket. Weird. Anyway, I'll score a Graf pump elsewhere, considerably cheaper than the OEM pump. Head removal gasket kit Includes HG, intake, exhaust, injector washers and O-rings, turbo to manifold gasket, turbo oil feed return grommet. I think the WP gasket too, but that should also be included in the pump. Front and rear crank seals. So far, I'm $1450 'deep' This includes shipping and bank wire charges to England. My local bank wanted 60 bucks for the 'fees'.. I found an online wire service that did it for 9 bucks. So, at this time, I'm at $1450 for 16 rockers 1 head gaskets ARP's both crank seals TB kit. Before I checked the box for which HG I need, I measured everything and confirmed I do indeed need a 1 hole gasket. I've never worked on an engine without first confirming the liner is sitting up to spec.. This one is no different. If they aren't where they need to be, or sunk, there are other issues that need addressing long before the head is bolted on. All 4 were in spec; zero to .0019 protrusion. Anyway, since I had my measuring tools out to measure liner protrusion, I went ahead and measured the pistons for their protrusion. Bingo. all in 'spec' for the 1 hole gasket Love it when everything is copasetic to the chart!! I'll have pics of this procedure next time. |

Great post rancherman. Especially on measuring and selecting the correct thickness head gasket based on liner and piston protrusion. One size DOES NOT fit all! Measurements and Clearances DO matter! |

Very Good writeup! Thanks for sharing. And as I have stated in some of our back and forth PM's; there is a reason for all the measurements and clearance requirements per the FSM. Building an engine and using the correct factory specifications and specified parts and gaskets based on real numbers is the main difference between shade tree mechanics and professional mechanics who strive to do it properly every time. Keep us posted as to your findings and progress. I hope you find no surprises going forward... |

Well, after dropping 'big bertha' on my right foot this afternoon, I managed to break 2 toes. So i'll be hobbling around for half the summer.. I did however get the adapter plate built to hang the engine on before screwing up the rest of the day! So much for 'professionalism' I built the engine stand to support 3000# large diesels.. and itself pushes 800#s.. There are no wheels, (main caps need to be 550 ft lbs on some of my engines, so definitely need something that stays put!!) so the only way to move it is by forklift, or today, roll the cherry picker into it, snag it, and wheel it around via the picker's wheels, then set it down where I need it. I didn't see that the stand was hung up on the cherry picker leg... and basically free fell the last 6 inches when I didn't see the carry chain was unhooked. I'm just glad it didn't 'separate' those toes from the rest of me! I'll be real interested in the imprint pattern on the liner shims.. especially the ones that are below spec. I'll spare you the 'imprint' pattern of my toes.. |

ohhhhhhhh, man I sympathize. Done my share of " What the heck did I do that for?" things. Glad you didn't lose any bodyparts. |

OUCH!!!!! I know that hurt like hell. Sorry for your misfortune, be careful going forward. Remember, "All accidents are preventable". Yea I know, a little late..... |

THAT is COOL!! EDIT: The engine stand... (The toe causes sympathetic pain) I've never seen one held that way, but can see the advantages! |

Thanks! quite common in the big diesel world.. hanging them from the side.. The really big brutes (900 cu in and up) will also have a mirror support that supports the far side too. This should help with crank extraction; go vertical, and simply snatch it out the top. I have a 'work step' that attaches to those open tubes on the top of the stand.. I'll stand on it and simply reach down and pull the crank straight up and out.. no rips, tears, or snags! Hopefully, I won't have to report a failed back flip attempt! |

I love the side attach on the block, only way to go which will allow complete access to both ends of the engine for crankshaft extraction.... SWEET!!!! But that Toe picture ain't pretty!!!! |
