I fixed it today, I waited all week because I had other stuff to do, and because I have the shop to myself Saturday (it's closed).
That way I can work without interruption.
I don't mind if customers talk to me
on their dime; when they ask me something I put my tools down and answer their queries. When the conversation stops, I pick up my tools and continue working. Meanwhile the clock is ticking.
I know the sound of a conrod knock a mile away.
Unfortunately when I first heard it I was 300kms away.
I kept it under 4500rpm and rode it home because I felt like it.
This is what I found when I ripped it apart this morning:
The left side shells were toast, right side was like new.
The left journal was crappy lookg but had not overheated, and no deep scars.
I don't know what caused this, both journals were squirting out tons of oil when I spun it with the starter.
Maybe it was a material defect.
I don't recall ever seeing a chunk like that missing from a shell that lacked oil.
I polished it with a shoelace wrapped around it and Mothers chrome polish.
Now it looks like this:
It should last a long time, I am giving myself a 5yr/100.000km warranty (parts. labour and towing) on the repair,
If I did this type of repair for a customer I would warranty it for 5 minutes or 5 feet (
excluding parts, labour and towing).
Because I felt like it, I checked the valves and guides; lapped all the valves, guides are perfect.
Before smashing it back together I installed the SS pushrod tubes I've had sitting around for ages, just for bling.
THEN, I changed the oil and filter, and guess what I found....
