Timing chain guides were well and truly stuffed. Most of the passenger side (driver's side for you yanks) guide was in the sump and the other side was broken in half. Surprisingly enough, the chain itself was actually within the limits of stretch. The timing case is pretty well cactus with a notable amount of corrosion through the coolant galleries - most notably a hole in the neck - as well as two rather deep gouges from the timing chain and the oil pump mounting face being scored from the pump picking up some foreign body. Pulled the pistons and rods out, which revealed a very light gouge in the #2 rod journal and some light scoring on the rearward side of the #2 cylinder. Measured the end gaps on the two compression rings on #2 out of curiosity to get a 0.95mm top ring gap and a 0.40mm second ring gap. The top ring is about 0.5mm more than the maximum service limit and the second ring is only just
within service limits. The coolant galleries in the block have quite a bit of crap caked down the bottom and the drain plug was redundant as there is a heap of caked up sludge which has formed it's own watertight seal. The sump is also dented badly enough to warrant replacing. The oil pickup is still good, but will benefit from a good clean to purge any crap it may have picked up.
The cylinder head seems to be in reasonable shape as it looks as though it was reconditioned or replaced with a fresh head at some point, though I am a little dubious about the threads on #4 spark plug hole. Rockers and rocker arms seem to be in pretty good condition, which is ideal. One of the camshaft caps was missing one of the little locating pin/dowels for some odd reason.
So the plan is to order some new 0.5mm oversize pistons and rings, a new oil pump and sump, as well as a bunch of odds and ends, including some locating dowels for the timing case and the camshaft cap in the head. I'll wait until I get the pieces to the machine shop to get some feedback on whether or not I'll need to worry about undersized bearings. I'll also be getting all the nuts/bolts and all the various brackets and mounts that I pulled off gold zinc plated for that factory fresh finish. I'm also planning on getting the valve cover vent welded shut and a -6 AN fitting welded where the PCV mounts.
That's about it for now. More to come over the next couple of weeks.
