Yanmar 3ym30f valve adjustment while installed

I do it in conjunction with an injector cleaning, cause I donít have a way to decompress the engine. Removal of the injectors of course wonít allow any compression.
Then Iíll use a plastic straw to determine TDC as my crankshaft timing marks are covered with a Serpentine belt kit.

But itís easy find TDC of a cylinder using the straw as an indicator of piston placement and TDC is easy to determine because both valves are a little loose, if TDC exhaust, they wonít be.

Now if you have indirect injection this isnít likely to work cause you canít get to the piston tops.
If you use an indicator like a plastic straw, be sure to use something that canít harm the piston, nor can be broken off.

Of course you can always download the engine manual and do it the right way, the procedure in the manual.

Don't get hung up on an actual clearance. Pick a feeler gauge to use as a Go/no go gauge.
