Who here done Timing Chain in SOHC, I can only find DOHC in archives

[lbrowne]

I'm pretty sure its close to the same procedure for dismantling everything. Fan, coolant hosing, intake, all that jazz to be removed.

I just can't find a write up on the SOHC. I know I have to take the oil pan off, which I hear can be a pain for the DOHC...is it the same for SOHC?

If anyone has done this before please fill me in.

Thanks,

Ive done it with the engine out of the car. Of course i was rebuilding the whole engine at the time, so that made it easier. Heres some things to remember:

Your goal is to remove the front cover, so you will have to remove the oil pump (there is a bolt hidden behind it). I believe you can get away with leaving the oil pan intact AS LONG as you remove the bolts that hold it to the front cover and somehow break the gasket sealer between the two. Again, i did this with my engine out of the car, but looking at it i dont see why it cant be done. Once the front cover is off you can remove the chain.

By now, its not 100% necissary to have the engine at TDC, because now you can loosen all the camshaft rocker arm retaining bolts to fully close all the valves. This way, you can rotate the crank and cam seperate of each other. The #1 cylinder is at TDC when the tooth on the crank sprocket points straight up. The cam is at TDC compression when the tooth points straight up. Now notice there are 2 dots, one at the 3 o'clock on the cam sprocket, and one at about the 5 o'clock on the crank. There are 2 silver links on the timing chain, these should match up with the 2 dots.

When reinstalling your oil pump, be sure to turn the shaft to align the matchmark on the gear shaft with the one on the pump. Lastly install the distributor with the rotor facing the #1 plug tower (about 5 o'clock) and make sure the half moon on it will mate with the half moon on the oil pump shaft. Use a good silicone sealer to seal it all back up. I would even disconnect your ignition coil wire and crank the engine over a few times before i started it.

This is by no means a complete write up. You should DEFINATELY get a FSM, or at least the Chiltons, they do at least have an exploded view of the engine outter accessories, which is what you are looking for.

Hope this helps some. Good luck!

well i have a chiltons, and i'll be referencing it quite a bit.

should i have to remove the front swaybar?

Only if it becomes absolutely necessary to remove the entire oil pan. In that case you will have to loosen the engine mount bolts and jack up the engine from the bottom to gain some clearance.

I have done this but it was on my pickup. I know the oil pan really doesn't NEED to be removed, but there is a silicone gasket that once the seal is broken would be difficult to replace. Besides it gives you the opportunity to clean out any debris or sludge that may have collected in the bottom of your pan. Or you can do what I did and give it a nice coat of paint that shows your attention to detail. Another thing is since you have the engine torn down do some internal mods if you have the cash. I put a Nismo hi-performance cam in my KA equip'd 95 Pickup.

Hi -

I did this job on my SOHC 240 about a month ago, and damn, all I can say is that it is a ***** of a job. Anyways, you don't have to take the oil pan all the way off, all you should have to do is take out the front-most four screws on the pan. The front cover is connected to the pan just by those screws and a bit of silicon.

If you got any other questions, let me know. And have fun prying the front cover off
