Re: Finding TDC for leak-down test

Just for context, are you asking these questions because there's something about your situation that would make hearing these sounds difficult?

Re: Finding TDC for leak-down test

I have an OTC 5609 cylinder leak tester, and the plan was to go to TDC and use regulated airflow to find out not only where the leak is but how severe. This will help me determine the cost/benefit...

Re: Finding TDC for leak-down test

I think it's still common practice in a lot of applications.

Re: Finding TDC for leak-down test

I agree, but my ability to diagnose visually is limited by experience, so I'd prefer to proceed carefully via quantitative analysis.

I feel like I got my answer with the crankshaft pulley rotation...

Re: Finding TDC for leak-down test

Thanks, I've already done compression and vacuum tests. These tests diagnosed 45 psi compression on #2 and loose valve guides overall. The purpose of the leak-down test is to see whether #2's issues...

Re: Finding TDC for leak-down test

I actually bought one of the dual-gauge leak-down testers, got the adapter, the whole nine yards. Just wasn't sure how to position the piston where I need it.

Re: Finding TDC for leak-down test

So the rotation of the crankshaft pulley would be:
TDC cylinder 1: 0 (with timing gear at dimple)
TDC cylinder 2: 180
TDC cylinder 4: 360
TDC cylinder 3: 540 (1.5x around)

Is that right?

Finding TDC for leak-down test

Hi folks,

Getting ready to do a leak-down test to check for valve issues on cylinder 2. What's the easiest way to find TDC on cylinders other than #1?

The only way I've thought of so far is to...

Re: Ammeter needle movements

It should move slightly negative most of the time when you turn the key. This indicates that the points are closed. This is why they say not to leave the key on without the engine running for more...

Re: Compression Test

Might be valves with those numbers. Like Mulletwagon said, possibly not worth fixing unless it's showing up in other ways.

Re: 6.1 High Compression Head

Maybe better phrased as "compression and airflow" after all, when you switched to the downdraft carbs I'm guessing you installed a new intake manifold.

Compression alone will improve performance...

Re: 6.1 High Compression Head

Upon inspection, it looks like dyno 1 is without the timing adjusted. Dyno 2 shows numbers that are closer to the Piranio numbers, though still lower.

I feel like there's enough unknowns about how...
