Ok, here's a pop quiz and the winner gets a slab of cold, tasty, Fosters Lager.  :thumb:

How many days does it take to time a car with a timing light and marks on the damper?   :bolt:

Hey Fitzy, don't worry about the timing taking so long, look on the bright side, it has 50 psi of oil pressure when cranking the starter, so if it ever does run, you at least know your oil pressure will be good.  :thumb:

Nice footage of a dashboard that needs some love, a pair of wipers, the hood, and the neighbour's house.

And there seems to be an engine running in the background.

Fitzy stop your  :cry:  What's wrong now ? .

We got the idle timing within 1 or 2 degrees of being perfect using the timing by "video" method, and it instantly starts and idles on its own after 20 seconds and there "was" no popping and it idled bitchen as seen in the last 10 seconds of the video i posted.

I had him start at what seems to be 12 degrees btdc [dont ask, long story] . It started after maybe 10 seconds of grinding and it barely idled and was slightly rough, so it needed a little more advance . I had him advance it to 16 degrees btdc and that was noticeably better and is what you see in the video . The idle is a hair low, but the way it idles is how that cam I had him get should idle cuz its moderately nasty and has .021" of lash.

After getting the idle timing correct, I had him move the plug wires so he could rotate the distributor so he would have a lot more room to adjust the timing before the dist cap hold down hit the intake . i then had him reset the timing to 16 degrees btdc and let it idle then had him advance the timing a little while it was idling . he said that it now ran rough at 16 degrees and advancing the timing made no difference . so now it ran rough at 16 but it didn't 30 minutes earlier so i had him check the plug wire routing again and it was fine.

I was then going to have him pull the plugs and take photos of them so i could see if any looked loaded up or if they were moist which would suggest water or oil, and was going to check the gaps etc, but before i had him do that, I had him look at the new oil and it has water in it, however, he didn't run the new oil in the engine to clean out the watered oil, he simply put the new oil in, turned the engine over a few times thinking that was enough to clean it out then drained it then put new expensive oil in it, so now I have no idea if the the oil is contaminated from the previous watered oil or if it still has a water leak.  :shrug:

The first intake gasket he installed was not done quite right, however, due to circumstances, we were not able to determine if it was the cause of the leak . He did have water in some of the intake ports after he took the intake off but i have no idea if that was because he did not drain the rad far enough or what . Maybe it was leaking and maybe it wasn't but something was leaking because there was definitely a boat load of water in the oil.

I then had him buy a special "fool proof" intake gasket and he said he followed my instructions to the letter . The original moron that built the engine got a flexible Fel-Pro 1250 gasket to leak, so based on all of this, it seems highly unlikely that the intake is now leaking.

I also mentioned to him back around page 1 that he will need an MSD box.

If you take spark plug photos, I need 4 in each photo from exactly, either of these angles with the electrodes all pointing the same way . The picture you take must look exactly like either of these . if it does not, it is useless.

Only 4 plugs in each photo.

Put the number of the cylinder on each plug with a felt pen as you take it out so you know what cylinder it came out of.

Line the plugs up in order 1, 2, 3, 4 then 5, 6, 7, 8.

If you put them on a piece of paper, you can also put the number of the plug on the paper so I can see which one it is.

Please do NOT clean or dry the plugs until I tell you it is ok to do so.

TIMING

WHAT NUMBER IS THE WHITE LINE ON THE DAMPER DRAWN ON?

I forgot what the timing was in the last video you sent me . I think it was 278 so I have no idea how we got to 282.


OIL

If you want to see if it has a water leak, you can buy the dirt cheapest oil and filter you can find, so Supercheap is your friend.

Don't forget that your car is at an angle, and that I mentioned that some of the oil might be sitting trapped in the rear of the oil pan because of the angle . If this is the case, there might have been a liter of watered oil left in there when you changed and this would certainly be enough to make your new oil look watered even if there isn't a leak, so as I said yesterday, don't jump to conclusions, only testing may tell us if you really do have a leak or not.

0. Carefully measure the water level in the rad . It should be around 25 mm below the bottom of the filler neck . If it is low, fill it to the correct level then measure it.

1. Buy 10 qts and two filters.

2. Loosen drain plug and let some oil dribble into a clear container . I want to see it there is any pure water that has sank to the bottom . After this, put the new oil and filter in.

3. After we fix the spark plugs, reinstall them into the same holes they came out of.

4. Set the timing to the timing mark at 276 or 278 [I forgot].

5. Take a video and start the engine.

Pump the gas half way to the floor twice then hold it down 1/4 of the way.

Start engine.

After it starts, hold the throttle down for 30 seconds a little farther than you did in the last video . I want it to rev higher than it did in the last video.

After 30 seconds, let it idle and walk to the back of the car and hold the phone around 3 feet away from the exhaust pipes for around 10 seconds.

After this, walk to the front of the car and video the engine for around 10 seconds like you did the last video.

After this, open the throttle quickly for a second . I want to see it it spits or sputters or hesitates etc . You can do this from under the hood or inside of the car or from both positions . If you do it under the hood, be careful of the fan blowing stuff into your eyes, especially blowing the gas around that is under the car.

6. Turn engine off.

7. Stop video.

8. Post video and wait for reply.

9. You can measure the water level again after the engine has sat for at least 30 minutes.

Just to clarify  :smile01:

All i did was drain the contaminated oil and change the filter and re fill it with new oil..

I assume i should have flushed it once or twice before i refilled it with the right oil ?

Only plugs that had a slight bit of moisture on them were 3 and 6. Others could have dried i suppose..

We did have the timing at 278 but you had me make a mark at 282 and we were working off that..  :shrug: :shrug:

when did you put the plugs in?

i cant see any wetness the white paper is making the camera make the end of the plugs too dark.

as i mentioned yesterday, you needed to run the engine at maybe 1500 rpm for maybe 15 minutes to get the oil warm and wash the watered oil off of all the surfaces and get it out of the lifters.

i said you may not currently have a leak since you did not do that because there might have been enough watered oil left to make the new pennrite look watered like it does now.

Plugs are about 5 mths old but they were only in for a week or so. I cleaned them completely till they were almost spotless.

That build up is just from the hand full of times we have been starting it etc. I cleaned them again only a few days ago..

The mark was at 278 but you had me move it to 282 and we were then working off that..  :shrug:

So the mark timing is on 282 in the video or 278?

WHICH PLUGS LOOKED MOIST/WET?

WHAT IS THE PLUG GAP?

The build up is from the crappy race carbs which look cool but work bad under 3000 rpm with big cams, but thats' ok, it s a "race car".  :thumb:

Now that we have the idle timing correct whatever it may have been at, the plugs "may" not get so black, however, my guess is that the carbs will need some tuning.

The dirty plugs may have been causing the miss and popping you heard.

At this point, I would clean the crap out of the plugs, then set the gap to .038" then reinstall them into the same holes.
