Ha! Sorry for your frustration.

Check the fuel pressure when it only cranks.

Any tears or cracks in the s-boot?

Are you still running points?

so, as is a common theme to my post, I take a break from chicken coup building and try again to start.

It starts, doesnt rev up, and stays running...but poorly and smoking. The engine never really smoked unless it had been a few weeks starting.

I didnt have the timing light out or anything ready to test/set timing, but a quick turn of the dist. did improve idle slightly. but it was still a lot of smoke from tail pipe.

What next? reset points? adjust timing? I may need a quick tutorial on setting timing with a dwell. Ive only set by light.

I was just about to say , I surrender and tow it to a local shop (though I realllly didnt want to).

So close,,,cant quit now.

other tidbit: There does seem to be a very small fuel leak on the ground below the #1 cylinder...but it is dry up top at the injectors,,,,

What color is the smoke?, white?, blue?, black?, purple?

white/gray, more white than gray.


per your suggestion I kept at every vacuum hose .The hose from the s boot to the aux regulator was a bit short so it didnt seat into the elbow at the aux reg too well. I cut some new hose and that helped!

seems there is a bit of an oil leak both sides that wasnt there before the engine was pulled. I havent traced it. The pushrod tube seals were replaced, I could have medded that up.

Starts and runs strong --although not totally smooth--but lots of grayish white smoke.

I did adjust valves while engine was out also. Could way out of whack adjustment (maladjustment) be a culprit in the smoke?

Valve adjustment shouldn't cause smoke, it could just be burning off buildup from sitting. The leaks may be valve covers not seated properly. Did the engine use oil prior to removing it?

Never used oil in excess and left very very minimal oil drops on ground.

Ill check the valve covers. Leak only happened after it ran.

The tin under the pushrods is still off so Ill try to see if the leaks are from the tubes.



Thanks!!

sometimes an engine will get laid at an odd angle when out that lets oil flow past the rings into the cylinder then exhaust.

it did tilt off to both sides (sometimes for a few minutes) at different times while using the ATV jack to lift the engine back into lace

havent drove it yet, but ran it for a few minutes...smoke slightly lightened after a few minutes...shut it down to take pics of the oil leak:

The oil that is leaking is coming from area circled in the image below. The oil smells slightly of gasoline.

Going to back it out of the garage and maybe drive it a bit during lunch.

The fuel smell in the oil is worrying me

still dripping a bit of oil (with a gas smell to it),,but smoking much less now...

The engine starts easily. But the idle does seem high and at times seems to slowly idle faster...

In another thread it was suggested to someone that a leaky valve gasket (vacuum leak?)can sometimes cause a higher idle. This could also be where my oil leak is coming from.

In what order should I do the following?

timing, adjust idle, re-adjust valves

Also if its idling too high will that affect the ability to set timing?

I will also see if adjusting the throttle/accelerator cable helps...

Fix the throttle cable, then wipe it down and run it some more to hopefully see where the leak originates. Your circled spot doesn't look like a valve cover or pushrod tube problem, it's more likely blowing forward from somewhere on top of the engine, like the breather tower base gasket, or the oil pressure sender.

You are correct about the timing, an idle over 1K rpm will skew the settings, try and get it down first. If you haven't messed with the speed screw on the throttle body, and it idled well before you removed it then it's something else you've disturbed during the re & re, a vacuum leak is still #1 suspect IMO.

might want to shine a light down where the oil sender is up top and see if it is oozing oil.

breather gasket is new. Off tomorrow show I should be able to do the above if I run out of light this evening.

is the slight smell of gas in that oil a big red flag?

And thanks again!!!!

It doesn't matter if it's new, look at it anyways. Gas smell is odd, but isn't pointing to one particular cause yet.

If you set your timing at full mechanical advance, 28° BTDC @3800+ rpms with the hose(s) off, a fast idle speed will not throw the timing off.

What happens to your idle when your remove the oil filler cap?

As suggested do check your oil pressure switch for leaks as they are notorious for oozing out oil.

engine was out but other than peripherals (plenum, air handler FI etc.) it was intact\...wasn't disassembled. was just out to freshen up the visual bits and to replace gas tank
