What is a decent air compressor on a budget.

@ryanhunt881 Жыл бұрын

@Brandon Weiss I have the craftsman 150psi 6gal pancake compressor and it works pretty good. I got mine for about $100 + another 20 or 30 for hoses etc. It works great for this kind of thing or airing up tires using an air blower and more light to medium duty stuff, just don’t expect to run a impact or anything large like that on it. Most grinders and cut off wheels are recommended to use on a larger compressor because of air capacity and run time but I have a cheap harbor freight angle grinder that works pretty decent on mine.

Anyone attempting to upgrade there truck past the simple cold air intake should own one of these testers. I ripped apart my ERG/ intake to be cleaned. Once put back together, my turbo whistled. This helped me track down a torn hot side boot and metal gaskets on the intake/ egr that I needed to replace/clean. Thank you

Good idea, but when are the exhaust valves could be open leaking out the air, sometimes you can't get enough pressure in the system to really see the leaks, best to put a plug right before the throttle body then test again

About to build this set up to test my Hot Rodded 12 valves RV's intercooler plumbing. It has 3" tubes but same concept. I will be also building a 2" set to test the radiator too, but will use water nozzles instead of air. Mainly because I want to flush out the radiator and engine before I get it ready to run. Funny how your video just popped up today after looking for parts to build one yesterday.....

For anyone in my situation, I ended up buying a 3" O.D. section of exhaust tubing, and used a hole saw to make a cap for it and welded it up. Worked great. Though I discovered you have to vacuum test your vacuum actuator to properly diagnose function, as that ended up being my issue.

I wouldn't use that rubber coupling for this tester. Those are only designed for like 3-4psi and is the reason why it's swelling up when you put 10psi in it. But it's a really good way of finding boost leaks quickly and cheaply!

@trackmedixuk 2 жыл бұрын

From what I have read, if the pressure guage is not attached to the cap it won't be a true psi reading. I personally thought the pressure guage on the gun would be good enough ?

I removed it cleaned everything up just in case and put it back on as tight as I thought would be safe and then tested again. If it's still leaking keep tightening. Be careful not to bend anything those clamps are very strong and could bend your piping.

@@jcbenson01 they're not equal in this regard. The terms boost leak and vacuum leak mean the same thing. Either the engine is in vacuum or pressurized under boost. If air is escaping, you're testing for leaks within that closed system, and therefore testing for a vacuum leak. AND a boost leak, simultaneously.

Doesn’t the air just go out the exhaust valves that are open if you try and pressurize the whole piping and intake manifold itself? I’d you start at the turbo inlet or turbo outlet? Where is your air source?

@juiceofsapho Жыл бұрын

From the video it is obvious he connected the adapter to the intake of the turbo (which normaly connects to the air filter hose), the turbo output is usually placed bellow the intake. It shouldn't make any difference I guess, beyond that it is probably easier to connect it to the intake of the turbo rather to the output hose of the turbo. The inlet engine valves "should" be all closed when the engine is shut down, since the last compression stroke that finally stops the engine should prevent that piston from reaching it's TDC, making all other pistons somewhere "in between" their TDC and BDC positions. Based on this, there should be no place for air to go from the point of connection to the turbo, except for the leaks of course ;) I am not 100% sure about this second part though, perhaps somebody here could verify it?

The intake valves will always be closed when the exhaust valves are open and vise versa.

@@austinsherwood7188there is a moment where both intake and exhaust valve is open at the same time, it’s when the piston is at the top dead center (not ignition time)

@aacar4095 3 ай бұрын

Thanks for the replies! So I talked to a company that manufactures a similar but more fancy version of these, and they said the valves shouldn't both be open (may depend on vehicle). They said start by removing the oil cap and going up to 5 psi, see if there are big leaks, and if so, try putting the cap on and seeing (carefully) if pressure builds up (indicating a bad pcv valve). If all is good, keep going up to 10, then 15. Nice looking units they sell at turboboostleaktesters
