We had our car compression tested in two reputable shop
1st shop reads
175.120.175.175
2nd shop reads
250.225.250.250
The car is 6 years old and 100T plus km reading
This two shops are good and reputable dito sa site so I won't mention the name
Baket magkaiba ng reading? is there something wrong with the car?

The simple test (i think) is to remove the cylinder head, turn it upside down and pour water on the valves (of cylinder 2) and wait. If water drains, then it's a leaking valve. If water doesn't drain, it's faulty piston rings.
As for the readings, I don't know if the difference is still within tolerance though.

November 20th, 2010 09:23 PM #3did the two shops mentioned here used the same setup and procedure to get the readings? did they use identical compression test equipment?
but one thing is obvious, both have low readings shown in cyl 2.

November 24th, 2010 11:03 AM #11Hi Malamang bro mali ung 2nd reading, baka mahina na ang spring ng gauge nun.
Kapag nasa 200 + ang compression cgurado mag piping ang makina sa unleaded gasoline.

December 17th, 2010 07:16 AM #12the compression can change from shop to shop. i wouldn't really worry about it since it might be different procedures and testers. what's obvious from both tests is that there's a cylinder down on compression so that's what you should be looking at.
