Hi...
It´s not a simple question... Confused

To check the timing, you will have to take your car front end out... Shocked

(As if, you were to change the cambelts). Start by taking the hood out, remove the front grille, raditator fan and radiator...

Then remove the belts for the water pump/alternator, power steering, and a/c (if your car is eqquiped with these). Remove the timing belt covers. Now you can see the cambelts. Cool

Next you will have to rotate the crankshaft until the cylinder Nº1 is at TDC.-To do this, remove the plastic cover, next to the distributor to see the markings on the flywheel (AHH i forgot Embarassed

; you also have to take the plugs out, and the distributor cap). Put your car in 2nd gear and push it gently, till the mark T is aligned with the small triangle. When this is done, the rotor arm, will be pointing to cylinder nº1 (Right bank, front one).
Now take a look at the cam pulleys. If all is ok, the markings, on them will also be aligned. (T marks, on the pulleys) Very Happy

.
If the timing is not correct, you will have to proceed as if you were to change your cambelts. Now, here starts the dificult part Shocked

. If you are not very gifted with your hands, you should stop here, reassemble all back on your car and go to an trusted mechanic. Confused

Hope this helps

Hi!

Well, it sounds pretty easy, but even though I only have 2 thumbs (instead of 10) on my hands, I think I'll let a mechanic take a look at it next week.. Wink

But thanks for the instructions! Very Happy

Regards,

ste dee · Guest

i ve got the same problem slightly different( ecu and cat model)
my 33 doesnt like starting when warm if ihave drove the car for a bit and then stop for an hour or so it stutters like crazy and pops and all sorts once it has run for a bit it settles down, im going to try messing with the throttle sensor
thanx

Yesterday I tried changing the TPS, AFM and the ECU..Nothing happened!! Confused

I'm afraid, that the next step will be fitting a lambda probe and 8 new lifters at cylinder 1 and 3... Rolling Eyes

And if that doesn't work either, I think I'll have to change some injectors. Evil or Very Mad

By the way, is it possible to mount the flywheel in a wrong position, so that it looks like the timing is correct but isn't because the cylinders dont match with the flywheel??
And is it possible to the adjust the ignition just by removing the distributor-cap and move the little stick inside..?

Just a few more things I'll check before dissambling the engine..again! Evil or Very Mad

Hi

...
Sorry to hear about your problems Sad

Have you checked the Rpm/timing sensor? It´s located between the engine/gearbox (on the flywheel), in the left side... Confused

It is worth to have a look, because your next step, will be disassemblig the engine... Evil or Very Mad

Also before changing injectors, you can measure their resistance with an multimeter (14/18 ohms) Idea

Hi,

I suppose that if the RPM-sensor was broken, the engine would run bad at all RPM. But it’s worth a check...

I've just checked the ignition, but to me it seems like the firing order is 2-1-3-4...But I think I will mention it to my mechanic and let him do the job! Shocked

Btw. can you (or anyone else) tell me where the different cylinders are placed? I've always thought, that 1 & 3 were on the LH (from inside the car) and 2 & 4 on the RH. But according to different topics I've been reading lately, it's seems like there is a bit of confusion about this...

While reading topics about this, it appeared that some have experienced wrong oil causing the noisy tappets (which I still see as the most likely reason for my rough running engine). But even if the oil was wrong, I suppose that the cams would still push the tappets and force them to open the valves completely, wouldn’t they!? Or have I misunderstood the way the tappets work..? Rolling Eyes

Regards Mads

As for the oil subject - I forgot to mention, that there is a lot (!!) of mayo in the oil-filler tube... Confused

doh!
could be a head gasket. i had a 1.5 s2 twin carb, with a blown gasket. it popped and banged all over the place.

get a compression test. cheap and fast way to check if there is a problem.

does the overflow water tank have oil in the water? this is another sign that there could be a blown gasket. (but best to get a compression test to make sure)

there is a way to get the error codes (sorry i cant remember how for the 33) from the ecu. this will tell you if something like the o2 (lambada) sensor is dead or any other part of the system. do a search as i know this has been covered before. 'error codes' or simething like that should turn up what you need.

good luck!

Hi...

The firing order is 1-3-2-4. (Cylinder nº 1-Front right / Cylinder nº2-Front left / Cylinder nº3-Back right / Cylinder nº 4-Back left)--This from the inside of the car.
As for the mayo in the oil filler tube, this is quite normal Sad

(not nice to see but normal). This usually happens when car doesnt get propperlly heated, used for short distance runs, and not a problem if the car doesn´t drink oil.
