So my trusty old 1700 supersprint xflow is showing signs of age. I did a compression test and #1 cyl is very low (in fact, they're all low). Readings were #1 to #4 (in bars on a Gunson compression tester) 5, 6, 6 and 6; with oil down the bores, 6, 8, 8 and 8. That doesn't sound good Symptoms are a chuffing & misfire at " class="smiley" />, and a truly horrible lumpy red paint job.
First, the HMR lump. I intend doing as little as possible on this engine.
1. Strip off the old paint on the block, repaint
2. Since the head is off, remove timing chain cover, ensure cams set properly for TDC
3. Get head gasket, clean & refit head
4. Fit new clutch, clutch plate (I have these already), spigot bearing
4. Replace water pump, dress with carbs, alternator etc from existing engine.
Questions; Since it's sat for a while, what else should I do to make sure it doesn't blow up on first crank? What gasket would be recommended? Any other stuff I should do? I did think of removing the sump & new gaskets as there's a slight weep, but I want to stop short of re-ringing, deglazing etc.
Once that's in, I'll look at the original engine and assess my options when it's apart. Again, what should I be looking for?
Got the rebuilding an xflow book btw.
