G'day Fellas.
Haven't done anything on the A's lately except for starting to pump the oil around.
The rHonda has the lump out and top end off after finding #4 was 30lb down on compression. It's been a battle as I thought it was a ring problem (oil squirt down the plug 'ol and it came up) but all looked good there. Found a leaky valve so lapped it in. On assembly I found the guide had lifted a mm
. These were new guides fitted 50,000Km ago. Decided to heat the head on the BBQ to 200C and push it back down. It didn't want to drop so put it up to 300C. It now dropped in easy. It wasn't till assembly (valves, springs, collets on 16 of the little buggers) I noticed a few of the seats had dropped a tad. OK, if I put it back in the BBQ at 350C the springs will pull the seats back in. It did but now had to lap all the valves back in and replace the seals again.
So yesterday with the head on the bench I bolted the cams in to adjust the shims (had already bought a kit of 26 @ $330) and got'em spot on with only one problem. Two of the cam cap bolts wouldn't tension up to 10ft/lb. Bugga, back apart again to helicoil those. All back together, now waiting on a set of std rings coming from Holland
Makes working on our A's a walk in the park.
Cheers
