Diesel Engine Compression Testing

[@DolphinDivingChamp]

Do you have to bottom out the fitting in the glow plug hole? Every single kit comes with a super short 12mm fitting thats definitely not gonna bottom

[@MarcoPereiraFerramenta-Online]

I've measured compression with this on several engines and haven't had this problem yet.

[@nickcurry5871]

.what is the accepted or normal range "psi" for Diesel engines?

[@MarcoPereiraFerramenta-Online]

In this engine it must be between 290psi and 390psi. But it depends on the engine , but in general a diesel engine has between 250psi and 400psi

[@nickcurry5871]

@@MarcoPereiraFerramenta-Online gotcha! i'll have mine to for a compression test next week. hopefully it will turn out healthy. i have a 2001 isuzu crosswind 4JA1 engine. Thanks again and keep safe!

[@surfreadjumpsleep]

Would you also do a wet test on the cylinder with 200psi? I read that a wet test will help you distinguish between bad cylinder / piston rings and the valves.

[@MarcoPereiraFerramenta-Online]

Hello in this case dont need to do a wet test, whit this values You Need to take the cilinder head off to se what is wrong whit the engine.

[@tiago10alves10]

Does that kit can be also used for petrol?

[@MarcoPereiraFerramenta-Online]

No, this is just for Diesel engines. The nosel and the Scale are diferent for petrol engines.

[@endlasaisreenivasulureddy823]

Is this placed in the glow-plug hole sir?

[@MarcoPereiraFerramenta-Online]

Yes, in this case it is on the glow plug hole. But you can mesure it by the injectores.

[@conmanumber1]

When gauge fail make sure you go to engineering supplier and get a calibrated Wika German made gauge.

How to prevent engine from not starting on other cylinders?

[@MarcoPereiraFerramenta-Online]

Hello. I turned off the diesel supply.

[@TomSon-ej3pw]

@@MarcoPereiraFerramenta-Online I've got high pressure pump and in that case it would work dry. I guess there must be some relief valve that could be opened instead.

[@bachirhassaine7668]

Thanks

[@lukey3507]

Shouldn't it be done wet & dry to test the piston rings

[@JD-xt8cj]

I know my service manual for my diesel says NOT to do the wet test

[@danmcnelly5901]

Did you do this on a warm engine?

[@MarcoPereiraFerramenta-Online]

Hello. No, the engine was cold.

[@Aquintal30]

This kit doesn't have an adapter to my renault megane and I purchased one, now how can I get one adapter??? That's a Hard one....

[@MarcoPereiraFerramenta-Online]

I bought this tool over the internet. I do not know if it has an adapter for Renault megane, I have not yet had to use it in any of those cars. Try to find it through the internet you might find it.

[@Aquintal30]

Marco Pereira I don't find it anywhere.... Unfortunetly.....

[@MarcoPereiraFerramenta-Online]

If you do not find it you have to try to make one.

[@Aquintal30]

Marco Pereira I will try, but that's not easy

[@MrJohnthefarmer]

You could try contacting 8milelake.com. This kit looks like theirs.

[@happyReek]

Who made the compression test kit?

[@MarcoPereiraFerramenta-Online]

This has no brand, I bought this tool over the internet.

[@happyReek]

could you tell me where to buy?

[@MarcoPereiraFerramenta-Online]

I bought mine on Ebay .

[@MrJohnthefarmer]

I purchased a very similar one on amazon. Just got it today. Worked well.

[@fulanito494]

How do you disable the injection to avoid engine start? thanks

[@MarcoPereiraFerramenta-Online]

I turned off the diesel shut off valve

[@gheorghinacov6008]

You could disconnect the electrical connections from the injectors.

[@ww07ff]

@@MarcoPereiraFerramenta-Online Is it at the high pressure pump?

[@TheDannydoe]

I normally just disconnect the fuse for the fuel pump. Takes 5 seconds and is easy to manage.

[@henriasi]

@@TheDannydoe Thats OK for petrol engines. Not a good idea for diesels.

[@bensaadabdessamed9308]

How accurate is this

[@MarcoPereiraFerramenta-Online]

Hello . Here it is not a question of precision or accuraci, what matters most when one measures that all are more or less equal.

Yes number 3 had a problem, as you can see in the video there was no compression as in the others.

[@SimpleDudeDoStuff]

[@loganlupi3695]

That's not how you do it you must take first stroke reading first then the then the build up

[@alexk581]

thumb down for not explaining and not providing any comments if you can't speak at least provide some comments

[@SuperBC10]

Maybe - but in all seriousness IF you are watching this then you are obviously a pretty competent DIY mechanic/potcher. Therefore no dialogue is really necessary. A beginner wouldn’t be able to comprehend that the glow plugs are coming off and probably wouldn’t even know that a diesel car has them (DI engines excepted of course).
