Question about Suzuki Sidekick

1 Answer

I just rebuilt my Sidekick engine, four cylinder 8 valve Sidekick. I had NAPA rebuild my head. After putting it all together I adjust the 1,2,5, and 7 valves at TDC, but when I rotate to do 3,4,6 and 8, number 7 has at least a half inch clearance between rocker arm and valve. After adjusting 3,4,6 and 8, and rotating back to TDC number 2 has that large clearance between rocker arm and valve. I checked the Crank shaft marker and the Cam marker and they are aligned at TDC. Any idea???

    Hey Biggdex35. Thanks for the response. Their not hydralic valves. Its just a 4 cylinder 8 valve overhead cam. I really believe my cam is off, but acording to the marks on the engine both the crank and cam are both dead on at TDC. If you get any ideas let me know. Im lost at the moment...

Did you pump up the lifters with oil? They are what oils the valves. As the motor runs they act as pumps and hydrolic shock absorbers at the same time. They pump oil up through the push rods. So when you try to adjust them they collapse and don't fill back up.

A drill press and push rod is the best way, tighten the pushrod into the chuck. Leave it off. then place the lifter in a small bowl of oil and press it down with the lever on drill. do it over and over until it gets hard to pump.

Need to know valve adjustment for 2012 ram 3500 turbo deisel and do you have to adjust the exaust valve n if so what is the spe. Tk. Joey


The 24-valve overhead system is a "low-maintenance"
design. Routine adjustments are no longer
necessary, however, measurement should still take
place when trouble-shooting performance problems,
or upon completion of a repair that includes removal
and installation of the valve train components or
injectors.
(1) Disconnect battery negative cables.
(2) Remove cylinder head cover (Refer to 9 -
ENGINE/CYLINDER HEAD/CYLINDER HEAD
COVER(S) - REMOVAL).
(3) Using the crankshaft barring tool #7471-B,
rotate crankshaft to align damper TDC mark to
12:00 o'clock position.
(a) If both number one cylinder rocker levers are
loose, continue to next step.
(b) If both number one clylinder rocker levers
are not loose, rotate crankshaft 360 degrees.
(4) With the engine in this position, valve lash can
be measured at the following rocker arms: INTAKE
1-2-4 / EXHAUST 1-3-5. Measure the valve lash by
inserting a feeler gauge between the rocker arm
socket and crosshead (Fig. 32). Refer to VALVE
LASH LIMIT CHART for the correct specifications. If
the measurement falls within the limits, adjustment/
resetting is not necessary. If measurement
finds the lash outside of the limits, adjustment/resetting
is required.
VALVE LASH LIMIT CHART
0.152 mm ( 0.006 in.)
MIN.
0.381 mm (0.015 in.)
MIN.
0.381 mm (0.015 in.)
MAX.
0.762 mm (0.030 in.)
MAX.
note:
If measured valve lash falls within these
specifications, no adjustment/reset is necessary.
Engine operation within these ranges has no adverse
affect on performance, emissions, fuel economy or
level of engine noise.
(5) If adjustment/resetting is required, loosen the
lock nut on rocker arms and turn the adjusting screw
until the desired lash is obtained:
² INTAKE 0.254 mm (0.010 in.)
² EXHAUST 0.508 mm (0.020 in.) Tighten the
lock nut to 24 Nm (18 ft. lbs.) and re-check the valve
lash.
(6) Using the crankshaft barring tool, rotate the
crankshaft one revolution (360°) to align the
damper TDC mark to the 12 o'clock position.
(7) With the engine in this position, valve lash can
be measured at the remaining rocker arms: INTAKE
3-5-6 / EXHAUST 2-4-6. Use the same method as
above for determining whether adjustment is necessary,
and adjust those that are found to be outside of
the limits.
(8) Install the cylinder head cover (Refer to 9 -
ENGINE/CYLINDER HEAD/CYLINDER HEAD
COVER(S) - INSTALLATION).
(9) Connect the battery negative cables.

Installed new piston rings and gas is getting inside oil


valve not closing is from a bent valve. Black soot is from over fuelling and incomplete combustion. Oily chamber is oil from the rings. It si possible that more than one valve is bent as it occurs from turning the engine over without letting of the rockers when adjusting the valve timing.

Is there ANY other engine that will fit in a 2002 jeep liberty limited? 3.7L v6... need a whole new engine


3.7L EKG Powertec, engine. SOHC with roller followers,
did you check compression, or just P030x codes???????
and what if its just a stuck valve or collapsed lifter
why not ask for help in diagnosis?
compression bad? on one or more? cylinders, post #
pull the Valve covers, see if there are broken valve springs
or bad cam lobes, or lifter bad? (motion)
if it didnt burn oil , try rebuilt heads.?

ran for 12 years, so what is the mileage>? 300k?
Oil changes, at 5000 ?

the 3.7 may fit...says wiki.
warning, some engine blocks may NOT be same. (filter mounts, engine mounts) check first.
but you can find this at any engine builders web site. (google them)
ive swapped many and engine, even wrong engines.?grin
there are always choices, i always have and had spare cars.
so down time is never an issue for me.
but others yes. (rent a car is one option while fixing another)
1: if the block is bad get a short block.
2: if the heads are bad get yours rebuilt , or exchanged.
3: if you blew the engine to total destruction, pistons hit valves? (rare)
then get a used engine, or buy a rebuilt.
or pull yours and take it to any top machine shop and drop it off.
bingo, fixed and cheap too. no middle man, to rip you.

history.
The 3.7 liter PowerTech V-6 engine is, essentially, the 4.7 V-8 with two fewer cylinders.
then later, morphed to the Pentastar V6. (today's motor)
cast iron block, (lasts long time, easy to bore and rebuild)
no rubberband cam belts, real chain, drive.
2 valves per cyl. making head rebuilds fast and cheaper.
forged pistons, not cheap cast.
MOPAR is not POS.
ask engineer Brian Crothers

I run the 3.8L in my 08 JK.
its a real low tech, push rod motor. (ended in 2011)

id fix mine, if it failed
my guess is it is head failure, , so get the newer
rebuilds with pinned, valve guides and run it.

Valve settings


- Pull the hand brake and put transmission in neutral.
- Remove spark plug cords.
- Remove the spark plugs.
- Remove the Tappet cover
- Lift up the left front wheel.
Cylinder number 1 is toward the pulleys and belts side.
- Rotate the crankshaft anticlockwise with socket and extension rod and bring the valve tappets (intake and exhaust) No. 4 cylinder on dancing position.
NOTE: THERE ARE OTHER WAYS ALSO TO ADJUST THE FOUR VALVES AT A TIME. BUT AS DIY FOLLOW THE FOLLOWING METHOD TO AVOID ANY CONFUSION.
- Adjust the valve clearance of number 1 cylinder.
Valve clearance:
Intake 0.18 - 0.22 (cold) Exhaust 0.25 - 0.28 (cold)
- Rotate the crankshaft anticlockwise to bring the valves of cylinder 2 on dancing position and adjust the valves of No. 3 cylinder.
- Similarly rotate the crankshaft to bring the valves of No. 1 cylinder on dancing position and adjust the valves of No. 4.
- Rotate the crankshaft anticlockwise to bring the valves of cylinder No. 3 on dancing position and adjust the valve clearance of No. 2 cylinder.

Will a broken timing chain on a 2000 Lincoln ls mess up the motor


Yes, normally what happen is it throw out the valve timing. That is, one or two piston could be effected here with its related intake and exhaust valves. What could happen, broken piston tops, bent valves or broken valves.


Since, the 2000 Lincoln has a 4.6 litre V8 engine it will double over head cams. This mean each side of the engine on this V8 has it own camshaft. Also, Ford could have installed a cam brake, that is if the timing is lost, it will stop all valves in both heads to a close position. I hope so, some 4 cylinder have this option.



If the engine doesn't have a camshaft brake then major overhaul. It would be easier to buy an rebuilt factory engine to install. A good engine remanufacture that rebuild engine for Ford, Chevy, Dodge, and other auto manufactures would be you best bet. In other words, they rebuild those engines the way Ford wants them to be rebuilt. Best of luck. GB...stewbison

Timing belt broke...was told i need new engine..is this right?


The 2.4L four has a belt and is not an interference engine according to the Gates timing belt application chart for your vehicle (check it out on Gates.com.) The 2.7L V-6 doesn't show that it needs a belt--so it has either a timing chain and gears or just gears. If the belt broke on the 2.4L four, you should be able to put on a new belt and go. The engine should not be damaged.

If the timing chain on the V-6 broke then engine damage may have occurred. Chain engines are sometimes not listed as interference because breaking a chain is so rare. The damage would probably be bent valves and damaged piston tops. The labor involved in repairing all that might cost more than just getting a rebuilt engine and putting it in.

V.w.jetta gas eng. timing belt broke ? .shut engine off then wood not start . dealer says needs head work ? bent valves? without disasembling is it possible valves never came into contact with pistons ?


Hi, im afraid i can only give you bad news im afraid, if the engine was running even on tick over when the belt snapped then this would have caused the valves to smash into the pistons as the top half of engine would have stopped spinning leaving at least 2 valves in the out position but what causes the damage is the bottom half of the engine, as their is no weight on the cams to keep them turning they stop at once but the bottom half the crank has a big weight called the fly wheel now when the belt snapped the cams would have stopped dead but the crank would have carried on turning under its own weight and this is what causes the piston or pistons to hit the valves this then causes the valves to bend and all the valves will need replacing and the whole top end rebuilding with new seals and the new valves and valve seats will need grinding in.

how ever as its only usually the top half that gets damaged you could save yourself some time and money by calling a local breakers yard and see if they have a cylinder head lying around or even a whole engine as the cost of rebuilding you head and engine would cost more than it would to get a second hand cylinder head or if you didnt want to take any chances look into getting a whole engine.

look at the costs involved get a quote off you garage for the head rebuilt and new valves, tell them worse case if it needed complete head rebuild with all new valves and valve seats and all the seals get a price on the whole job then ask them how much it would cost if you supplied a working cylinder head or even whole engine then compare the prices and check with some breakers for cylinder head prices or engine and you should find that a second hand head will work out cheaper than having yours stripped and rebuilt with new parts.

let me know how you get on or if you need further assistance ok

please rate this solution as i have a whole page of unrated posts, thanks
