Checking compression
Hi guys, wanted to ask if I would be able to check the compression with both of my cams off. I got a 1.6 LT dual oh VTEC/ '95 Del Sol
I'm removing the head to check if any of my valves are bent after the timing belt broke.
I did try to install a new belt, and the motor did run afterwords, but not too good though...
Had to advance the timing all the way, to be able to drive the car. I suspect I have low compression because of bent valves.
Also, do you guys know a way to get to the lower intake manifold retaing nuts (can't even get my hand in there to check!) Thanks

With both camshafts out, aren't all four valves on all combustion chambers closed?
If I where to remove the all four spark plugs, and alternatively hook up the compression gauge to each chamber, shouldn't I be able to measure compression when the piston is on TDC? Thanks

Just wanted to see what kind of compression I have, before I take the head out, mh...mh... I mean off.
Do the valves have guides? is there a good chance that the bent valves have bad guides also? Some time ago the timing belt broke on my Alfa Romeo GTV, and that's exactly what happened: three bent valves and their respective guides had to be replaced! Thanks
