I know this isn't the right place to post this but does anyone know where I could get a quality leakdown tester for a good price ? (other than Snap-On)

Get a Snap-Off I mean Snap-On. They are around 250.

 

work great too!

 

I should have said 'other than Snap-On'. I know they work great but they're on the pricy side. Any other sources ?

 

Summit $65.99 Part #900010

 

You can make you own for even less.

 

Do you know what parts are required ? Seems that I've seen most of
the parts displayed at Home Depot or Sears.

If I can't find the parts, I'll just buy it from Summit

build your own tester

I bought this Leakdown tester from Summit. Which end is the input and which is the output (into the spark plug sockets)? lol I think the red hose screws into the spark plug sockets but im not sure if its fitted to the leakdown tester on the right side in hte picture. I called summit and the way the guy from summit described it - the peice where the red hose is fitted to is the input and where youd plug in a compressor hose.

And what size is the threading on the red hose? Called summit and they dont know. 14mm and 18mm is the other end that goes into the spark plug sockets not the hose diamater.

 

Is it just me or does that look like a compression tester and not a leakdown tester? I've never seen the 2 gauge deal but it sure is damn similar if it is actually a leakdown tester. And how would it determine where its leaking from?

 

The two gauge version shows you input pressure, as well as pressure lost.


How do you determine where its leaking from?

Intake = intake valve
Exhaust = exhaust valves
Oil cap = rings

 

yo i had questions!

 

The way its pictured in your thread above is correct. The red hose goes to the sparkplug hole. The 2 pieces look like adapters for different spark plugs holes.

The compressed air fits in near the regulator.

If i get a good compression test reading.. is there any reason to do a leak down test?

 

No. Leakdown testing indicates what % of leakage you have in each cyclindar and it can also be used to help determine where the leakage is occuring.

 

i tried to build my own it didnt really work at all. i ended up just using a friends later down the road. for the money i spent i could have bought one off ebay.
