1995 jeep 4.0 valve train clearance

What year is the vehicle? Most modern cars often don't need the valve clearances adjusted. They are fitted with Hydraulic 'Tappets' that automatically adjust to suit the valve clearances as the engine warms up. You can usually tell by looking at the valve rockers. Hydraulic set ups don't have adjustment screws fitted to the ends of the rocker.

Valve lash is the end of the rocker arm and the valve stem clearance between. When the engine is running, due to the thermal expansion and contraction, if there is no gap between the rocker arm and the valve stem, rocker arm swells, the top valve open, the impact of engine power and economy. Engine valve clearance will be different, usually when the car is cold, the intake valve 0.08-0.10MM, clearance exhaust valves 0.10-0.12MM Car Diagnostic Tool

if it does not have hydraulic adjusters then .012" inlet hot and .014" exhaust hot. If it has hydraulic adjusters then the noise will be from worn rocker shafts and rocker bushes.

There is no torque spec for rockers. You tighten until there is no backlash, then preload another 1/4 to 1/2 turn. With #1 at TDC on the compression stroke, you adjust #1 by this procedure. You can also adjust intake valves on #'s 2, 5 & 7 as well as exhaust on 3's 1, 3, 4 & 8. Then rotate the engine until #6 is TDC on compression stroke and adjust intakes on #'s 3. 4. 6 & 8 and exhaust on #'s 2, 5, 6 & 7. Good luck.

Take the rocker cover and the upper timing belt cover off.
Set No 1 Cylinder to TDC - use the markings on the cam spocket to get this - and confirm it's on the compression stroke by check both inlet and exhaust valves are closed and on the heel of the cam.
In this position, check rockers 1,2,4 and 5.
Take care with the feeler guage to make sure you're right under the pad under the adjuster screw properly and completely passing under it, not sticking part way.
Rotate the engine (crank shaft) 360 degrees. This should bring No 4 to TDC - confirm that both inlet and exhaust valves are closed and on the heel of the cam.
In this position, check rockers 3,6,7 and 8.

Clearance for Intake and Exhaust is 0.25mm at normal engine operating temp.

Don't forget to fit a new rocker cover gasket and half moon seal (use something like Hylomar to help make sure the half moon is sealed properly - usual suspect when rocker cover leaks at the back of the engine).

This is the specs for the 4H Diesel engine:
Intake valves clearance cold 0.4mm(.016inches)
Exhaust valve clearance cold 0.4mm(.016inches)

make sure engine is warmed up. Put cylinder one at top dead center,remove the valve cover,loosen all adjustment lock nuts,adust intake and exhaust valves on cyl #1 and intake valve on #2 and exhaust valve on #3. now rotate crankshaft 360 degrees clockwise, now adjust intake valves on cyl#3 and cyl #4 and exhaust valves on cyl #2 and cyl #4.now tighten lock nuts and install valve cover. specs are intake valves 25mm clearance and exhaust 28mm clearance, use a feeler gauge,heres a picture to show you where to check clearance.

You have hydraulic lifters which are not adjustable. Torque setting for rocker bridges is 19 foot lbs. If valvetrain is noisy, lifters or cam need replacement, unless rocker pivots are visibly worn.

According to http://freespace.virgin.net/tommy.sandham/databook.htm# Rocker Adjustment, the cold clearance is .008" intake/.018" exhaust in the non-GT 1500cc, and .012" intake/.022 exhaust on the GT. Sweet little car!!!

On the intake 0.0008 or 0.0020 (it's in between these 2)

this is for the stem to guide clearance. (for the intake)

The Exhaust 0.0018 to 0.0030 stem to guide clearance.
