Here is a video on performing a compression test on an engine to assess it’s mechanical condition. An engines ability to compress air and fuel is directly proportional to it’s performance since an engine is nothing more than an air compressor once you take away all the controls. A compression test is a good general test that will give you an idea of the engine’s overall health but it does not give specific information on what the problem is should there be one, for that a “leak down test” would be required, here is a link to that video. www.youtube.com However if you find yourself looking for the source of a performance problem with an engine, this is a great place to start. This test is often overlooked in favor of looking at the fuel or ignition system, I think that’s a mistake, if an engine can’t perform mechanically no amount of electronics will make that better. Recently, I hit the 500 subscriber mark and I’d like to thank all of my subscribers past, present, and hopefully in the future for that. I enjoy making these videos and the fact that you seem to like watching them means a lot to me. So, thanks for subscribing, rating, and commenting, those little contributions make it all worth while. Visit me at EricTheCarGuy.com ericthecarguy.com Also see the video I did, “Octane Ratings and the 4 Stroke Engine Cycle” for more information on how compression works and why it is important. www.youtube.com Thanks for watching andstay dirty ETCG Due to factors beyond the …

Follow me on Twitter @kyletwentytwo PS Vita remote play NOTE: I couldn’t connect to the media server because that was the wrong one! (Yeah, I’m dumb) Media server DOES WORK REMOTELY 
What if you don’t torque the rocker arm down to the right spec? Would that give you a hesitation on acceleration?
hey eric i have a srt 4 neon im going to do a compression test today. the reason being intermittently at idle my car is burning oil any ideas. has 124K nd runs good just burning oil blue smoke not good thanks
Wish u were local to me so you’ll b my go to guy for all my service needs…I enjoy watching all your videos
@greatdane114 Just 1 bar difference would be enough to show some kind of problem. You need to start using a smaller fraction. That is why most working preasures are done in PSI, Pounds per Square Inch. 1 Bar is about 14.5 PSI. Just 1 bar difference is 14.5 PSI, I would be looking for less difference than this. Also remember to do the test cold, and then run the engine and do it hot.
@rushymoto (continued) But this would not test the real integrity of the engine but just give me a comparison between cylinders. I am really only needing to check for valve damage due to the timing chain jumping a tooth on the front cam shaft. I am making the maximum effort to try and avoid taking the cylinder head off as I hate working on modern cars, To little room for my fingers.
Can you please tell me what kind of preassure I can expect form a Diesel test? I have the Ford 4 cylinder common rail diesel that is the 2.0 litre and having the timing chain. Installed in a Mondeo. (UK name) I was thinking I could turn up a solid adaptor to extend up from the injector hole up to the outside world that has space inside its tubular shape to add to the combustion chamber, reducing the compression ratio and thus allowing me to use my tester that is for a gas engine.
Real good video, I learned a lot from it
I have a 1997 Honda Prelude 2.2 vtec. I got 18 / 17 / 18 / 18 (bar)
(18 bar = 261 psi and 17 bar = 246 psi)
What does this mean please? This is really high isn’t it?
hi ericthecarguy did you pull out the fuel pump fuse or relay
i got a question, a new chevy 350 just buuilt, 2 weeks later, some lifters leak down, ive replaced them again, same thing, any helpfull advice???? thanks
good videos…its you and scotty kilmer head to head now..oth of you are very well explained and presented…Blessings
Hi ericthecarguy i ask you do i need hold wide open the throttle because i saw another video
that this guy put the pliers to hold the throtle is neccesary??
Hi Eric-
I have an 84 Bronco with a 351 Cleveland with 4V heads. I’m going to do a compression test. Should the engine be warmed up prior to doing it? Also, should all the plugs be removed before doing it? Would you know about what amount of compression that I should be expecting if all the valves, head gaskets and rings are all right? Thanks
@vTeChRDC5 k20 type r? what exact engine code is that? If you can figure out what compression ratio that engine has you can use a conversion calculator to calculate the amount of psi it should be pushing out.
Thanks for the help
Ah not to worry.. I found the manual for the car, it said test at normal operating temperatures
Hi, should a compression test be carried out when the engine is cold or up to operating temps?
Found the video very interesting ! ive learned a lot from your video ! thank you
Good video! Subscribed
Very nice breakdown Eric. Learned a lot from it and will apply the same steps in my shop. You earned another subscriber.
@Choirboyjr11 business,more profit if a bigger component is sold than a little one like a sleeve.
thanks for the videoes.
Eric the fun guy
how come auto manufacturers don’t sleeve engines in the first place like some diesels so instead of boring it out or junking a block you can just replace the sleeves?
very informative,i dont kno how some pple can thumbs down this vid maybe they are mechanic that work at the dealer or shops haters lol.
I have a 150cc gy6 engine in my scooter. It misfires at higher speed/rpms.
It starts very good, idles nice and has good acceleration. But when I get up to near top speed (40mph +) it starts to misfire.
If I had a burnt valve, would it still start and run very good, only to start misfiring at higher speeds?
Could the valve gap being off .001 in. be enough to make it misfire like that?
Thumbs up if your gf broke up with you because she saw on your Facebook status “I <3 Vita!” and asked “Who the fuck is Vita??”
Jk, I’m still single.
NBA 2K12 (and any other game) are not supported because the PS Vita hasn’t been released to the public yet. There is supposed to be a patch sometime around the February release that will allow you to play almost any game with remote play from your PS3.
@Potatopoison Yes
I pre ordered my vita already and now I can’t wait till Feb 22!!
you can connect to a media server via remore play you just havent got it set up properly on your PC.
@Shuturmouthyounglady i have a 3ds and i love it but that doesnt mean im not getting the vita in my opinion the vita is better than the 3ds!
How about the L2 and R2?
I dont want a vita because the 3DS is out and owning.
vita should be thrown in the dump.
want a vita soooo bad
Can’t play disc on vita from remote play. But what about playing the downloaded ps3 games on remote play?
I know killzone 3 works on vita remote play but does something like cod work? Please respond!
could i do this if i was not in the house like in the car or somewhere else?
@ncaissie what u mean
Let psx game die already.
@lorenzodabeast I think you mean sexy.
if they would release nba 2K and Fight Night then i’ll buy this one.
thumbs up if you think the ps vita looks sick
@zpennant Just swing it over your shoulder so it doesn’t fall in.
@H8Me909 no, as it is the same format as the “Dark Souls” game he tried…but then again, like he said, developers could add extra code to certain games to allow for remote play support…we shall have to see
Nothing different to the psp’s
@zpennant holy shit me too. I thought I was the only one who was germaphobic about that shit
Will mw3 work on remote play?
You have a cool voice and a cool white ps3.
@zpennant ur dick must be pretty small if it only reaches the iinside of ur toilet bowl!!! hahaha!!!!
@tirpakdaniel Hey dude, you can check my channel for facebook video of PS Vita. I have made an in-depth internet video focusing on flash and facebook PS Vita.
