Puff of Blue Smoke in between gears? Valve seal question.

Post by lostboy »

I get a puff of blue smoke in between gears following a high vacuum situations it seems. It's pretty thick, but dissipates quickly.

Im hoping it's just the valve seals. I am going to do the seals with the heads on the engine.

Should I upgrade the valve springs while I'm at it to some dual springs? Its a 61. I know I've seen here that the early single springs are quite weak. Thanks

Before tear down, a compression test and leak down test on any low compression cylinders is appropriate.
