How to set Valve clearence in Mitsubish Lance 1987 Engin model G15B


When Piston 1 is at TDC, (timing points inline), both valves are closed and there should be a gap, say 12 thou on exhaust and 8 thou on inlet. Turn the engine until Piston 2 is at TDC, (both valves closed as with number 1) and adjust, keep going until all pistons have had the clearance set.

What is the clearance between the rocker arm and the valve spring in a GM 2.2L motor


there is no specification for what you want
the valve clearance is between the end of the rocker arm and the end if the valve stem
the stem end is proud of the spring retainer so if your rocker arm is touching the spring retainer , you have a big problem as for the procedure it is set out in the workshop manual but if you don't have a manual it can be done like this
you will need the firing order of the engine first
now adjust no 1 piston valves when the next piston to fire has the valves in the rock position
that is the exhaust valve just closing as the inlet is just opening a bit of movement of the crank makes either valve move up or down
adjust no 1 piston valves
now move on to the next piston to fire and adjust the valves that were rocking
follow that procedure until all the valves are adjusted
for example
on a 4 cylinder engine with a firing order of 1--3--4--2
bring up no 1 piston and adjust the valves when the valves on no 3 piston are rocking
next piston to fire is no 4 so adjust no 2 piston valves
next piston to fire is no 2 so adjust the valves when no 1 valves are rocking
the procedure is the same for engines with any number of cylinders

How do I adjust valve clearance on 912/3 deutz engine


firing order is 1-2-3
so when no 2 cylinder valves are in the rock position ( exhaust closing at the same time as inlet is opening) that will be no 1 piston tdc compression stroke adjust the both valves to the specification
.006" both valves
when no3 piston has valve rock adjust no 2 cylinder valves
when no 1 has valve rock adjust no 3 cylinder valves
go google and type in valve clearance of deutz 3 cylinder engine
there is another method explained where inlet of one cylinder and exhaust
this is done with one full revolution of the crank

I had a broken timing belt and replaced the heads, valve stems, seals, gaskets and springs. how do I time the piston to valve clearance to prevent kissing.


you don't change the piston to valve clearance
the valve timing does that as it opens and closes the valves so that the piston doesn't hit it
all the details for timing the valves are in the workshop manual as you have not bothered to include the make, model ,year and engine type in your post

How do you check the valves on a 1993 onan 24 horse motor


MEASURE AND ADJUST VALVE CLEARANCE 1. Turn the flywheel clockwise until the intake valve opens and then closes. Continue turning flywheel until the TDC (top-dead-center) mark (A) on the flywheel is upward. Both valves (B) must be closed and the piston (C) must be at the top of its compression stroke. If the valves are open, the piston is on the exhaust stroke and the flywheel must be turned one revolution
2. Measure valve clearance using a feeler gauge. VALVE CLEARANCE SPECIFICATION Item Specification Intake Valve (A) . . . . . . . . . . . . . . . . . . . . . . . 0.13 mm (0.005 in.) Exhaust Valve (B) . . . . . . . . . . . . . . . . . . . . . . 0.33 mm (0.013 in.)
3. If necessary, hold tappet and turn tappet screw to adjust valve clearance

How to adjust travel


1 intake down
2 compress up
3 power stroke down
4 exhaust up




if you start with you start with the piston just a couple of degrees past TDC (top dead center) so that it has started its return down


now set the valves so they are closed:
if you have an adjustable valve clearance's then your clearances should be noticeable like 10 thousands ( you should be able to move the lifter ( rocker arm ) and it will be loose up and down


with the spark plug still out; so you can see the piston coming to TDC and passing it to come down


turn the flywheel and watch the strokes and the condition of the valves


1 just past tdc, the intake valve opens and the piston goes down for the intake stroke


2. jst as the piston comes around BDC the intake valve should close and return to tdc with all valves closed ( the compression stroke )


3 just past TDC the ignition will fire and the piston will return down with both valves closed( the power stroke)


4 just past BDC the exhaust valve opend , the piston travels up and completes the exgaust stroke.




and after completing the exhause stroke and arriving at tdc the intake valve opens and you start over again 1,2,3,4

Timing belt not broke, but engine has no compression on a 1997 chrysler sebring.


You have a zero clearance engine, meaning there is no room for clearance between the pistons when they're up and the valves are closed. If the belt broke there is a high probability that the valve(s) came in contact with the pistons and caused significant damage to the valve, valves, or cylinder head.

get the engine on top dead center, take valve caps off turn over engine slowly until intake valve just closes u will be close to top dead center there. then i use a small long screwdriver i put in sparkplug hole and turn engine very slow when piston just startes to go back down i adj valves. intake valve 3 thousands and ex valve 5 thousands
