My car is the SE model. It will not start. It has gas and fire. What is the best way to check the timing with out pulling down the motor? Also, the motor is a 3.0 dohc.
Do you
have the same problem?
Yes
No

Hi and thanks for using 2CarPros.com.

If you are concerned about timing, honestly the best way is to check the timing chain, but that would require removal of the timing chain covers and inspection. However, if you want, you could do a compression test. If the timing is off, the compression will most likely be low. Here are general directions for checking compression:

If you find that one of the three timing chains could be an issue, here are directions for removal and replacement. They are quite extensive, but can be done in the vehicle. The first twenty four pictures correlate with removal of the chains and water pump which I would recommend you do at the same time.

Position upper timing chains on idler sprockets by aligning the mating marks on the idler sprockets with the gold mating marks on the upper timing chains.
Install oil pump drive spacer, front cover and alternator adjusting bar.
Before installing front cover, remove all traces of liquid gasket from mating surface and grooves using a scraper and then completely clean any oil stains.
Also remove traces of liquid gasket from mating surface of cylinder block.
Apply a continuous bead of liquid gasket to mating surface of front cover.
Use Genuine Liquid Gasket or equivalent.
Wipe off excessive liquid gasket.
Install oil filter bracket.
Install oil strainer.

Set No.1 piston at T.D.C. on its compression stroke.
Install oil pan.
Install water pump.
Before installing water pump, remove all traces of liquid gasket from mating surface and groove using a scraper.
Also remove traces of liquid gasket from mating surface of front cover and water pipe.
Apply a continuous bead of liquid gasket to mating surface of water pump.
Use Genuine Liquid Gasket or equivalent.
Install water pump pulley.
Install water pipe.
Turn crankshaft until No.1 piston is set at approximately 120° before T.D.C. on compression stroke to prevent interference of valves and pistons.
Install cylinder heads with new gaskets.
Before installing cylinder head gaskets, apply a continuous bead of liquid gasket to mating surface of cylinder block.
Be sure to install washers between bolts and cylinder head.
Do not rotate crankshaft and camshaft separately, or valves will strike piston heads.
Tightening procedure:
Tighten all bolts to 39 Nm (4.0 kg-m, 29 ft-lb) .
Bolts of A type: Turn A bolts 65 to 70 degrees clockwise with Tool or suitable angle wrench.

Please keep in mind, the directions also include replacing head gaskets which you will not be doing.

I hope this helps. I realize it is extensive, but if you find a chain has jumped, I figured I would give you the directions.

Take care and let me know if you have questions,

Joe
