The size, number, and positions of the oiling holes in the rocker shafts were designed by Toyota engineers. In all the years I've been around the 22s, I've NEVER heard of or read about anyone saying that the shafts or the rockers have inadequate oil lubrication.Perhaps LCE's shafts are designed with a better or more advanced level of engineering? Toyota has designed and built this type of engine for 5 decades... so what does LCE know that the world's best automotive engineers do not?What proof does LCE have that their design is superior to Toyota's, or that Toyota's stock design is inadequate for sufficient lubrication? LCE has a good reputation as a Toyota engine engineering company? Perhaps they do know and have proof that their design is better and provides some level of longer life or reduced wear for the rockers and shaft.I'd like to see the proof.Gnarls.
Realized over the weekend that I need fresh head bolts.
For online, engnbldr is a good source and price.Gnarls.
The 20-22R head bolts are not torque to yield, and Toyota does not advise replacement evertime the head is removed.I have reused head bolts for years unless they are rusted, and then I replace them with used ones!In todays world of fancy engines, almost ever engine uses torque to yield headbolts The machine shop was playing it safe when they told you to replace them. Look them over carefully, and if they look good, you know what I would do.75 to 84' head bolt 12x1.25mm thread 166.5mm long90910-02058 list $4.66 times 10=$46.60
I'm not experienced with 1985-95 headbolts vs 79-84...
OK then if Marlin said it I will use a decent set from one of the blocks I tore down this year.
I was tired this morning, it was 20 degrees and the wind was blowing like an essobee, so I decided to do some light work. Consolidated the greasy boxes of parts in the house, then I dug up a couple oil pans. I was really considering using the later model because it has a flange intended for FIPG instead of a gasket, but the drain plug on the early style still has me hooked. The old one has a nice fat, hard to strip, 19mm head plug with a big fat drain hole that drops your oil in a few seconds.In this case I say older is better. Sraped all the sludge off of the pan. The whole project took about an hour from finding to cleaning.New time: 32.5 Hours
I have both oil pans sitting around, and I think even a 2wd one. I will be using the tiny drain plug one with the FIPG seal...it drains quick enough and I already painted it lol
you painted the block heater man.
