number on block?

[Terry_samurai]

Hi all,

I would like to know what the numbers mean on the side of a cylinder head? I have a 1.6 8V vitara engine in my samurai and the head went on it so i went to scrappy got another head and put it on started then died so played with the dizzy and it would only tick over if was all the way towards the dash but is ticking over at about 2500RPM I had a look at the blocks and on the inlet manifold side the number/letters on old/nackered block are 60A sp-1 and on the scrappy block i got the numbers are 60A sp-2 and the anus is doing about 50mph max at a push have to drop it down to 4th to get up the smallest of hills. Im not happy i want my anus back to how it was. please please help me . so any help would be great.

Many thanks.

It sounds like you don't have the timing right between the crankshaft and the camshaft. Maybe something got bumped while you were installing the timing belt...

In order to get everything exactly right, you need to:

BE SURE THAT YOU REMOVE THE ACCESSORY BELT PULLEY ON THE CRANKSHAFT BY REMOVING THE 5 SMALL BOLTS THAT HOLD IT IN PLACE. DO NOT REMOVE THE LARGE CRANKSHAFT BOLT IN THE CENTER! (Sorry, It's a "thing" I have about how too many blocks have been ruined because someone needlessly removed the big bolt and did not get it back on tight enough...)

1. Set the camshaft and the crankshaft so that the marks on the face of the pulleys are straight up.

2. Using the Samurai Manual (yes, it'll work for the 1.6 in many instances too), carefully re-install the timing belt and hand-turn the engine CLOCKWISE with the crankshaft bolt (17mm, I believe) to properly tension the belt.

3. Continue to turn the crankshaft until the marks on the face of the pulleys are straight up as in the first step.

4. Remove the valve cover and carefully examine the cam lobes to determine which cylinder is at Top Dead Center (TDC) with the valves closed - TDC Ignition. The ones with both lobes pointing away from the vave stems is at TDC Ignition. It will be either the #1 or the #4 cylinder. (My bet is #1...)

5. Reinstall the distributor so that the rotor points to the TDC Ignition cylinder's sparkplug wire point. This may take a few tries to get it to line up... Don't forget to try to install the distrbutor so the adjuster bolt is near the center of the adjustment range!

6. Replace the valve cover and wire up the rest of the sparkplug wires in proper order .

Unless I am a complete moron, your engine should start right up and is ready for fine timing adjustment!

I hope that this helps!

sorry to be a dumbass but how do you then fine tune the timing.?

With a timing light hooked up to your tdc ht lead 1or4. Whatever one of the two you have set it too, most likely #1

Set it to 10degrees btdc then shine it at the timing marks on the flywheel through the bellhousing and adjust the dizzy to the point that the timing marks line up as it is flashing.

You'll see what I mean as you are doing it.
