DAWGTOY Puppy Mill Maker   Joined: 14 Nov 2005 Posts: 2684 last saturday steven brought me his old mill--the one with the homemade side inspection hole. sunday i tore it down. besides having a broken rod and trashed crank i think i discovered what might have caused the problem. whoever put in the last timing chain put the wrong bolt in the oil pump (the only one thats important) which bound up the timing chain tensioner causing the chain to slap around grinding off most of the timing chain guide bolts. (steel backed dual row) i think that pieces of bolts somehow got in the # 1 rod bearings and caused the bearing to fail breaking the rod. when the rod broke the piston must have shot up in the cylinder and then the intake valve hit the piston bending the valve. i've never seen a steel backed guide break like this one--the whole mounting plate was broken off and the guide itself was just grinding around on the timing chain. every thing is going well on the replacement engine. the block, head and crank are at the machine shop awaiting service. the cam and rockers look as good as any i've ever torn down but the valve adjustment screws will need replaced. (they are pitted bad on the bottom). it's always good when the cam and rockers are good cause rockers are pricey and i really don't think the replacements are very good quality.(unless they are factory replacements) this engine will end up being 20 over in bore size and 10-20 over for the crank and rod bearings. i'm gonna balance the rotating assembly and gasket match the intake and exaust ports--polish the valves and do a mild pocket port job. should end up being a nice stock runner. keep in mind steven that if you want a different cam we'll need new rockers as well. i won't put used rockers on a new camshaft no matter how good they look. have you found a header yet? let me know what you find. i finished balancing the rods. they are ready to go. new small end bushings and they all weigh within .5 gram of each other. as soon as i know for sure what size the pistons and rod bearings need to be i'll order the rebuild kit. should know somthing a little later this week. dawg btw i got pix of all this on my camera so you can see what i'm talkin about. _________________ new crawler in the works.

The bottom flange has been cut off but that's no biggie. _________________ DAWGTOY wrote: We need healthy gals in our sport.

StevenK Webwheeler   Joined: 09 Jan 2012 Posts: 34 Location: Burnsville, NC Thanks for the update. Sounds like the last owner made a pretty big mistake with that bolt. Makes me kinda leery about other areas of the truck. Robert: Are these the headers you were talking about? http://dougthorleyheaders.com/products/searchType/vehicleSearch/year/1982/make/TOYOTA/model/TRUCK/sfID1/9/sfID2/40/sfID3/39 Doesn't have a picture on the website, so I'm not sure if it is tri-y or not. I'll go with your judgement on the cam/rockers. I really don't have the knowledge base to make that call. All I want is a good long, reliable life out of the engine. If the current cam/rockers will provide that, I'm fine with keeping them. If not, feel free to replace them.

DAWGTOY Puppy Mill Maker   Joined: 14 Nov 2005 Posts: 2684 over the weekend i disassembled the rocker shafts. soaked everything in gas overnight. then spent a couple hours with a brass brush, bore brushes, steel wool and a air blower to clean em up. everything looks like new. i'll need to get new valve adjustment studs as these are pitted bad where they ride on the valve. the block will be 20 over in bore size. i'm still waiting on the crank. slowly coming together. dawg _________________ new crawler in the works.

DAWGTOY Puppy Mill Maker   Joined: 14 Nov 2005 Posts: 2684 yesterday i picked up the rebuild kit. includes all gaskets and seals--rod and main bearings 10 over-- new pistons and rings 20 over---timing chain and guides (steel backed dual row). i still need an oil pump--i'll get it later. last night i finished polishing the valves (weight balanced to within .5 gram) weighted the pistons,rings,rods,bearings,piston pins and clips so i have an overall weight to give the machine shop so they can balance the crank. the block should be finished bored today. i'll leave the front cover and valve cover with them to be cleaned when i pick it up. it'll be good to get the block back so i can start cleaning and painting it. after the machine shop is finished balancing the crank i can start assembly. tonight i'll finish gasket matching the ports, clean, lap in the valves and reassemble the head. it's gettin there. dododawg _________________ new crawler in the works.

DAWGTOY Puppy Mill Maker   Joined: 14 Nov 2005 Posts: 2684 cool thanks for checkin on it. lets see -- what did i do last night.not a lot to the engine work. i did take the carb off the intake so i could clean it up well. i finished tearing down the old block and put it in the junkyard. i had a little help last night so we unloaded my truck, parked the rv in it's spot and started tearing down the trailer. seems like i did somthing else in regards to the rebuild but it escapes me at this time. today i pick up the block. the reassembly process begins. i'll make sure to take plenty o pix for ya. when you come down next time bring your laptop and you can put the pix on there. the pix are split between two memory cards (one ran out of space) so bring your card reader. if you don't have one maybe we can get them straight off the camera. dawg _________________ new crawler in the works.
