Today I used my friend's contraption/bushing/thing to reface the broken bolt in the engine mount. Then bought some new bits and drilled through the bolt with a 5/16". Took a long time. Not sure how true or square it is. Now I have to wait for him to come and try to remove what is left of the bolt.
It wasn't true/square. Used heat and an extractor without success. Drilled out larger and then pushed out pieces what was left of it (out the back), which took threads with it. Photos of largest chunk attached. So we will have to use an insert. I expected as much.
Finished the valve adjustment. So now clearances are as follows:
1in .006/.008 2in .006/.006 3in .007/.007 4in .008/.007
1ex .009/.009 2ex .009/.009 3ex .008/.008 4ex .008/.008Replaced spark plugs. One was slightly overgapped. None looked all that bad, but all replaced with new. Changed all the gaskets, put back on cam over, put back exhaust cam sensor with oversized O ring. Changed oil, cleaned throttle bodies. Tons of reassembly left to do, some day, so it can be tested.
Noticed the right fan has a little grinding noise when free-spun, the left one doesn't do that.
