Facing the engine, look down at the top, left of the crank pulley. You will see a post sticking out of the block. With the engine running, if you shine a timing light at the post you will see six notches on the pulley itself, right at the edge of the belt. Going from left to right the notches represent 10ATDC, TDC (red), 10BTDC, 20BTDC, 30BTDC, 40BTDC. The Top Dead Center notch is actually painted red, all the others are either rust or grease colored depending on how bad you valve cover gasket is leaking. Keep in mind this is only for the initial timing at idle of 20BTDC. Any rpms beyond idle and the ECU takes over the ignition timing, you have very little control here. The method for setting is to unplug the throttle pos. sensor, set idle to 650 and set to 20 BTDC. When you reconnect the TPS the rpms should increase to 750. Either way 750 is your optimal rpm and all adjustment must be done with the TPS disconnected, only disconnect and reconect the TPS with the ignition off. Never yank it or plug it in while the car is running. P.S. Try to keep all of your fingers here, its a tight spot to see down to those marks. ---Brandon Garretson ------89 240SX
first, remove the spark plug from #1, bring piston to TDC(you can see the piston in the hole or use timing marks on dampener pulley) then remove dist. cap, where the metal piece faces is #1 then goes counterclockwise 3 4 2. then you can turn the distributor itself to tweak timing once the car is running
It could be the timing chain guides. 240sx engines are notorious for this. The timing chain guides are made of cheap plastic and they wear out and break off after time. When the engine is started, the pieces get kicked up from the bottom of the oil pan and make a racket for a while. I don't think is causes much harm, though.
