issue with timing- distributor being replaced
well, i had to replace my distributor. it was my first time (i'm a diesel guy and this is my first gasser).
how do i set timing after replacing a distributor? i DO know how to successfully use a light, but read on.
i was reading the directions that came with the unit and it says not to start my engine with the timing incorrect or i could harm my engine
now.... how in the hell do i set my timing with my engine not running!?
also, any tips on installing my distributor? should i apply dielectric grease anywhere, and where?
the car has been off the road for some time now and this is the last thing i need to do to get her running, the quicker the reply the awesome-r

Re: issue with timing- distributor being replaced
first off rotate engine to # 1 cylinder tdc on the compression stroke this is important you can tell by the movement of the rockers opening and closing , then find the point at wich the tistributor rotor is aligned with the #1 spark plug terminal on the cap , so when you install the dissy you have the #1 piston at tdc and the #1 terminal is aligned with the rotor this gives you a rough idea of 0 degrees timing and you should be able to start you car saftly i've done it this way 5 0000000 times and never any problems just be sure not to run your engine with timing less than 2 degrees btdc for it wont hurt it to run it like this for a few minutes but u don't wanna do any driving with the timeing set incorrectly cuz u could do some harm and will prolly run mad lean and will run kinda shitty unless ur running 14.5:1 compression . and there you go very easy compared to diesel ehh only the fuel pump to adjust the timing GOOD LUCK

sorry to be such a simpleton... my engine is in my car. how would i rotate my engine so cyl 1 is TDC with the engine in? i've only done it with an engine out of the car.

Re: issue with timing- distributor being replaced
If you do not have a breaker bar or the big socket, you can always "bump" the starter several times (with the coil disconnected) to turn it to #1 TDC on compression stroke. You just need to seriously only "bump" the key to turn the engine only a few degrees at a time.
Hope this helps.

Re: issue with timing- distributor being replaced
yeah, but the distributor isn't tightened down and the dist. advance moves so how can i tell if its actually at 1 on the cap? when i put my dist in the rotor button is pointing straight to the front of motor dead center.
