7MGTE Cressida compression figure?

[Cuthbert]

Hey what compression values should I get when testing a 7MGTE? Anyone know where I can buy a cheap compression tester? eg. supercheap? will they work well enough.

i think its around 150psi? yeah cheapo will do, get one that screws in tho not the ones with the rubber dick u just hold down.
also make sure your batteries good for all that cranking.

thanks, you get a rep point for that one.

I got 195 psi, I cranked each cylinder about 7 times, is this too much or is there such a thing as too much?

[RA35GT]

While it does seem high but theres no saying how accurate the gauge is.

Whats important is that all cylinders read approximately the same when using the same gauge.

[Cuthbert]

The gauge was borrowed from a Mechanics workshop, should have asked him how to use it I guess. Borrowed from a friend's friend.

All were basically the same, one was about 190 so all good.

seems high but a cold test will usually give a higher reading too,

All the instruction manuals i've read with comp testers say crank 4 times only
