Heads and valves oh my

Using our new tool, we were successfully able to remove the valve springs, keepers, and valves. ¬†Although we’ve yet to measure anything, not a single valve had any issue with the seat or clearance. Only one valve has a slight mushroom on top of the head so we need to lightly grind it down so that we can remove it.

Even though these are 882’s with 76CC, we’re still going to reuse them in this rebuild ūüôā Rather than take them to a machine shop for¬†tanking, we opted to clean them ourself by soaking them in purple power for a week. ¬†They came out great, in our final wash before assembly, we will ensure rust and any residue is removed.

Needed More Tools

The valve spring remover I have right now requires too much patience to use. It’s one of the small hand-held types that hook onto the spring with 2 legs, and you crank down the compressor by hand. ¬†Sometimes it falls right off, other times it just stares at you doing nothing. ¬†So I opted to replace it for a more useful, sturdy one. ¬†The bearing tool is only for SBC but it was dirt cheap and until I can find a better one on craigslist, it got the job done.

Finally getting into it

Unfortunately, I’ve been spending all my spare time either at baseball or working. ¬†However, we’re¬†getting back into the groove today.

Cracked the heads off and pulled off the oil pan – it’s a 4 bolt main (figured), and visually looks great. ¬†We rotated the pistons again and watched for knocking and clearance on the rods – no knocking and the clearance looks perfect.

A few piston skirts appear to have rubbed against the bore – I¬†think they collapsed, but won’t know for¬†sure until I measure. ¬†The bores otherwise still have crosshatching which is slightly surprising. ¬†I really want to reuse the pistons and rings and am hoping I don’t need to bore this. ¬†There is a ridge at the top of each cylinder bore, so again, assume we aren’t having to bore this out, honing will clean that up.

The cam is getting thrown away – 2 of the lobes are practically round!

Because of all the sludge, we pressure washed the block thoroughly with hot water and purple power degreaser.

We are going to remove the bearings a different day.
