Mulitfuel compression check

Any body out there made a compression tool out of a injector, if so how well did it work and what are the details, thanks.

We made a air injector to change out one of the valve springs . Just make shure you tap deep so the fitting has lots of threads and don't be in the line of fire when you go to use it. We had no problem but do be careful.

Thanks for your time.

I have heard of a compression testing kit that threaded into a glow plug home. I am not certain, but I would imagine that they must make a kit for non-glow plug trucks since it is really an essential test to determine the balance internally of an engine in terms of wear.
I would stop at a truck shop that repairs and possibly rebuilds diesels and see if you can borrow, or rent theirs.

I was think someone on the site made on using a injector, I could be wrong,nothing came up using the search.

Hi Kip;
No doubt you would have to utilize the injector bore to access the combustion chamber. The trick is to have a gauge that reads upwards of 600 psi or so to get a reading and one that functions like a comrpession gauge would be most useful as it records the highest deflection.
Best of luck

You can borrow my injector/ tester if you pay shipping both ways or I can look to see if I have an old injector you can make your own.

I had talked about making one this summer when the deuce was dead. I ended up not making it because, with some help fom the site here, I removed head from ass and figured out I had put the HH on backwards. If it becomes necessary, pm me and I'll see about finishing it. - Andrew

would like to see a picture, I have plenty of spare injectors, Floridianson, thanks for the offer, have you built one yet, or was yours purchased?

 

[Floridianson]

My friend built it.

 

[kipman]

Do you have time to take a picture and post it up?

 

[Floridianson]

It is 60 miles from here but you just dismantel the injector guts and tip then blind tap the head for the fitting.

You might also just be able to use the thread size that is on the head and bushing up to the correct size of the fitting you will be useing. That way no dammage is done.

That answers my question, thanks.
