1999 Camry, no compression in Cylinder 1?

Cylinder 1. With the timing belt off, I rotated the crankshaft, and got no change in pressure, no matter how many times I rotated the crankshaft.

chance of getting the compression stroke...

Oh I think I know why I have no compression. Gauge threads aren't for my Camry. Only 1/2 turn and the hose comes out. Taking the 50-50

Unless you think you have a blown head gasket, I wouldn't worry about compression. How many miles does this thing have on it?

I was hoping to use the compression tester to find TDC, as the Haynes manua l suggested.

I took the 50-50, figuring if worst comes to worst, it just won't start, bu t the car started right up! (I used the old timing belt for the test.)

If I'm off by one timing belt notch, will fuel economy suffer? I was going by the marks on the crankshaft gear, since I read somewhere that the notch on the crankshaft pulley can be off because the rubber on the pulley deter iorates... and I think that happened in my case.

you need to get it exactly right, something will suffer if you don't, drivability, idle, power, fuel mileage... probably all of them.

Yeah... I tried the engine again when it was 15 degrees *after* TDC, and to my astonishment it sounded just fine, like you'd never know it was off... I found that disturbing.

Then of course I set the timing belt to TDC.

astonishment it sounded just fine, like you'd never know it was off... I found that disturbing.

They will often sound fine off by that much at idle. You would surely notice less power driving though.
