[@mattschamel6550]

This video is 8 years old and I'm just now seeing it!? Awesome video! Extremely informative! Thanks!

[@honeybadger2332]

Even though this video is 6 years old it was the most informative video I have seen yet. Good job!!

[@basementblues9681]

Amazing film Justin, good to see Blackline Racing is still active, "Good Road"

[@markporden5794]

Best video I have seen on the subject of engine engine testing ever

[@chrisburnsed6349]

Fantastic explanations. Clear and easy to understand with no irrelevant bs. Great job

[@ElJeffe_]

One of the best videos Ive ever watched on any topic. Top notch. Thanks!

[@bonnieslocum]

You explain things so well Justin. I'm no mechanic but have always been interested in knowing more about it. I'm always surprising people by attempting to do mechanic work on my car myself by learning from You Tube videos. I've even been successful a few times. I need videos like this. You are so easy to understand. I feel the confidence to do it myself with your instruction.

[@Michael-xe3jf]

Amazing video 😮you made the most sense and I learnt more in this video than anything else I have read.👍👍 I have a 1981 puma gti from Brazil and I have lack of power at different rpm’s. I am new at this but thank you 🙏

[@bedlamite42]

23:30 NO! The stock threads are not pipe thread, they are M10x1.0. If you thread an NPT gauge into it you can damage the threads and cause an oil leak.

[@Fatcatbaz]

Justin I realise that this video has been on KZbin for two years now. However I have only just stumbled across your video. I need to say that this is the most informative video that I have ever seen on compression and leak-down testing. Really well delivered and it gives me the confidence to start carrying out these tests for myself. Kind Regards Barry

[@unclesolomon6029]

I've watched a whole bucketfull of VW videos and this is way above all the rest. Justin, thanks. I am inspired by your knowledge, preparation and thoroughness.

[@jeffetzel850]

One of the best informative videos. To help you buy a motor.

[@vivauruguay]

Very clear and down to the point I have learned a lot and this will help me to complete my 66 vw.

[@laytonturpin6957]

Concise and to the point. I’ve been building internal combustion engines for the better part of 45 years. You hit every nail on the head. I hope the business in the background is yours. You’re going to do excellent! I enjoyed your movie thoroughly. Take care!

[@romandolan7809]

Watched this again after about a year, makes more sense to me now. Really great info vid, but not sure how much of this could be done before buying the motor

[@kennethmaser1767]

Thanks Justin, Great info for testing that engine. We just picked up a 72 VW dune Buggy and I will be sure to check these things out when we start on the engine.

[@michaelboisselle8590]

Awesome video thanks for the detailed information

[@malcolmyoung7866]

Great video, Justin explains the process and what to be aware of very well. Think many of my friends who have aircooled VW's could benefit from this. Going to subscribe...

[@ranzamaceanruig]

Phenomenal video. Easy to follow and understand. Thanks for a ton of great info Justin!

[@secondlooksformen3836]

Great testing, top job

[@chuckcafiero4546]

do a tutorial on all types and mods of the air cooled vw oiling systems.

[@johncollins5552]

Excellent video. I used a compression tester last year and didn't know the throttle had to be opened.I know now.In future could you do a common bolt on upgrade comparison for stock,before and after for exhaust vs quietpack,1.25 rocker vs 1.4,single carb vs dual.That would take the guesswork out of buying parts!

[@ShamWerks]

Great vid, thanks for all the valuable information! :)

[@creativespark1539]

one of t he best videos out there good info Thanks

[@hamlulit]

Amazing explanatory video! thanks

[@richardwarnock2789]

Justin pretty good information!!, Just wondering about those sumps added on I made the pick up tube drop lower inside the screen filter wondering is neasary to do that and used adjustable oil pressure relief valve to this at the time was a 1835 build engine?!

[@SRV-gi7vr]

Great video. I have a couple of questions for you. I need to change my valve guides and was wondering how many thousandths loose do you ream the guides. Should I purchase adjustable reamers or the drill bit type reamer? Once I remove the old guides and mic them, should I replace them with .001 or .002 over? Thanks

[@washingtonfootballfanwgil8392]

I own a 78 convertible. I don't have the first clue what you're explaining. I'm trying to learn from scratch.

[@directsound]

Can you do this if you drained the oil?

[@harryloibl5183]

Cool thanks buddy

[@Michael-xe3jf]

You just got a follow 👍👍

[@coupe481234]

Do you rebuild engines . I've got a bare block made in Mexico.?

[@frankiebernard576]

great video

[@ericgraff2976]

Great info man

[@paulgarza8389]

now that my 1600 engine is out and i am going to replace the passenger side head due to a stripped plug thread....do i have to remove the fan shroud to gain access to the upper nuts on the head ?

[@daos3300]

great vid. other ideas? anything you've got!

[@andrewoneill5003]

Great “movie” very helpful.

[@harryloibl5183]

Is it okay to use a striker crank on a original magnesium case thanks

[@craig265]

I bought a new set of Pacino's from CB performance heads and I live in Sacramento CA. The first two months seem to be great. Now the car runs really sluggish and it's summertime. I'm curious is there a shortcut to finding out if the heads are cracked. Without taking the heads off the heads off ?.....

[@MrGarcon98]

QUESTION PLEASE i watched a video from drag racing tv here on utube and they are saying on a dual case 1600 oil pressure relief in the front NOT TO USE A GROOVED PISTON ? do you know why not ? thank you october 2020 thanks in advance ,,,,

[@SpangeBatta]

hi justin great video! only 1 question! can you do a compression test on the engine by cranking it over yourself? im building a type 4 2257cc stroker vw engine but i only have a engine stand NO GEARBOX AND STARTER or do i need a special RPM to get ik goinG? i have new /rework heads and pistons en liners but no good compression! do you need to oil the liners and pistons first to get compression? thanks joris de vet // the netherlands

[@MrGarcon98]

how about some videos on vw front beam work any good vids worth listening to ? like the death wobble and cure !

[@noahriedel801]

Can someone please explain the hot maroon color stuff that's on the head where the manifold and exhaust bolt??????

[@dublininnis9695]

Well done is all I can say

[@carlosz7208]

Great video. Does the engine have to be cold or warm when doing the compression test?

[@ahmedelwensh9320]

Good question, i hope u got the answer But in my opinion, it's not that hard not to test twice, cold and hot .

[@JoshDavis-m9b]

I done a compression test on my 1835 and now it won't start.

[@blacklineracing]

If it ran beforehand and all you did was a compression test then most likely the problem will be with spark plug wires installed on the wrong plugs. Also make sure you have a rotor in the distributor.

[@bearvw1966]

Justin, where is your location?

[@paulgarza8389]

how come you did not follow a career in music like your dad ?

[@frankiebella5745]

come to my house do my Porsche 911 😀👍
