Hello Oldsmobile enthusiasts. I have an issue with my 73 engine tues over but won't start up. I check spark it's there I check fuel is there. Timing marks were off but did step by step and put them as close as possible . cam mark at 12oclocl and crank at 6. Went and tryed and start and nothing. Help please any ideas or tips are apreciarse...

 

Is the firing order wired CCW? Did you find #1 TDC, set the rotor position, and wire from there? If yes, then rotate the distributor clockwise a bit while someone cranks the engine.

 

Yes the firing order is correct 1,8,4,3,6,5,7,2...I'm give that a try later on today... Are both valves suppose to be close at tec??

 

Did you get it started?

 

Unfortunately no sjay1989...all it gives me is a puff of smoke and small explosion...not giving up yet tho I'm taking a break and doing some research.

 

Yes both valves should be closed at #1 TDC on the compression stroke and the rockers/valves should not move if the crank is moved slightly in either direction.

At the same time the valves on #6 should be closed but open with any movement in either direction of the crank.

 

That's a great tip sugarbear ..as I said I was doing some research on line a as well on the Chilton books a guy said timing marks on olds engine line up but the top timing marks at 12oclock and the bottom also at 13 o'clock but I seen that on YouTube I try cross reference but no luck..ill try posting the link..thanks again for the tip bud

 

Why do I get the feeling we are not being told everything ? A total of 4 posts and all 4 are on this thread. No posting on the Newbie forum. Cam/crank timing marks ? How would you see them if the engine was assembled?
Timing marks were off but did a step by step and put them as close as possible. What "timing marks" are you referring to ?
Are you sure you are on the compression stroke for #1 ? How did you determine that you were on the compression stroke ?
When did the engine run last time ? What have you done to it since it ran ?

 

Well oldster thats as much as i know . guy o bought it from got the car the same way dead engine he said he didn't lay a hand on the car . now it does have bent pushrods on on cylender #2 only all rockers lloverá great. And i am new here lol guy suggest to sing up and get some info. I took the engine apart to see if the timing was right do that itll turnover but won't start.and yes i did do the step by step part..as for the timming marks on both the top gear and the small bottom veas. Yes both valves are closed at tdc. And Well i still have it apart....

 

Was the timing set changed? Bent pushrods mean something crashed inside the engine in most cases.

 

When you have old gas it’ll back fire and bend the pushrods. I’ve seen it happen more than once.

 

You need to find the guy who owned it before the guy that sold it to you. You have an engine of unknown condition. You have 2 bent pushrods. Have you set the ignition timing ? How long do you plan to run the engine without coolant in the block and heads ?

 

@2:20 is this tru??? Thoughts ? And I appreciate the tips guy��

 

You can install it with the crank at 12:00 and cam at 6 or 12. The difference is whether the engine is firing on #1 or #6. Depending on how its installed, you would have to turn the crank one full turn to install the distributor.
