Need advice regarding low compression/white smoke (1 Viewer)

How does one rotate the engine manually? Ugh I’m lame... spark plugs removed just don’t see how to manually turn things.

Starter works well

So I did it while running my intake valve on #5 is loose. I was able to fit the 0.011 in there and spec is 0.008

Ooh good news! After adjusting intake valve I got 130 on cylinder #5!!! Now to put everything back together and take it for a little spin.

And strangely my spark plugs are burning more normal beige color now. Wonder if the altitude caused them to burn a bit richer.

Low compression white smoke? Granted I'm late to your thread.....sounds like a hairline crack, not in head, but perhaps the thermostat housing...I just completed rebuilding my upper and lower engine while its all in the truck. found the crack on the lower water outlet housing, and the two front headbolts were a full turn loose....

valves were adjusted fine and the engine ran great to redline (often)..... then one day in late August....wham! overheated and boiled out my coolant, right near San Ramon/580 westbound. Just about all my coolant was gone from steaming out through front cylinder and the tiny crack... So good luck and check the torque on headbolts, since you have the valve cover off so often

BTW, hope to meetcha at Fort Point on Sunday to witness the Toolbox handoff

I need to lower my oil level too. Will do that this weekend before the Cross Country Expedition into San Francisco. Maybe I’ll try one of the steep hills there and see if I get that white smoke...

I have a pretty much new thermostat housing that would be shocking if it were that. But anything’s possible.

I didn’t check my head bolts probably should’ve done that since I had things apart. This was my first time taking the valve cover off in quite some time. I’m hoping that my valve adjustment was the trick. I’ll keep an eye out for other signs.

Great hope to see you Sunday!
