Results from Compression Test

Hi guys,

Had my new '94 EF Falcon serviced today and got a compression test done while they were at it. When I picked my car up my mechanic had gone out so I didn't get the chance to ask him about my compression test results, I'm just wondering if I could get some comments on the results :)

Cylinder 1. 125psi
Cylinder 2. 100psi
Cylinder 3. 100psi
Cylinder 4. 115psi
Cylinder 5. 110psi
Cylinder 6. 105psi

Thanks for all your comments,

Nick.

Re: Results from Compression Test

The variation is normal and acceptable. I can't however comment on the actual absolute figures as I only know what my figures were on the 8.

Re: Results from Compression Test

Yeah I would have taken a stab and said that they sounded a little low. My windsor ranged from 160psi to 175psi from memory. I'm assuming that this was a dry compression test?

Ummm i have no idea :)
My mechanic rang me a little while ago to give me the run down on the service and to apologise for not being there, he said around 105psi is the norm, also said I picked up a little gem too :)
Got a new surge/overflow tank for no charge aswell because mine was leaking air around the cap and I happened to give him a carton for some weekend work he did for me on my old car :)

Re: Results from Compression Test

yea depends on what tester they are using there are different ones that give different readings.. I got one done on my ef and got 115 for every one then got it done when my cvar got serviced 3 days after and got 190 for every one... best bet is to ask mechanic that did the test ... (which u have done )

Lovin the manual xr6!!!

Re: Results from Compression Test

Basically as long as they're even it's OK.
100 range is probably a little low, but not too bad in my experience.

Re: Results from Compression Test

The pressure tester I used was "snap-on" brand.
